The aim of this study was to analyze the overall welfare state on Serbian dairy farms, as well to suggest measures for its improvement. The assessment was done according to Welfare Quality® Assessment Protocol for Dairy Cows on 16 selected commercial farms in which the cows of Simmental and Holstein-Friesian breeds were reared (N=4833). Welfare state on each farm was evaluated by relevant measures that indicated insurance of appropriate feeding, housing, health and behavior as basic principles of welfare. Overall score (0-100 points) enabled finally categorization of farms into one of four welfare category (not classified, acceptable, enhanced and excellent).Based on results, half of the farms were assigned to acceptable, and other half to enhanced welfare category. Housing conditions on the majority of farms (63%) were assessed as unacceptable (≤20 points) due to poor hygiene and discomfort. Cows were kept tied continuously on more than one third of farms which together with lack of pasture (17 days/year on average) restricting their comfort and freedom of movement. This may be also linked to low scored behavioral insurance (32points), especially inability to express its natural forms (6.7 points).Health condition was estimated as acceptable, but endangered welfare by high incidence of laminitis (38%), distocya (4.2%) and mortality (6.7%). Commonly performed dehorning procedure (79%) without anesthetic/analgesic application caused pain and stress in affected animals. Overall assessment score (2.5/5) showed the need for improvement in all areas of dairy cows' welfare, especially in terms of their housing and management., Cilj ovog istraživanja bio je da se analizira stanje dobrobiti na mlečnim farmama u Srbiji, kao i da se predlože mere za njegovo unapređenje. Ocena stanja dobrobiti obavljena je putem Protokola za ocenu kvaliteta dobrobiti mlečnih krava na 16 odabranih komercijalnih farmi na kojima su gajene krave simentalske i holštajn-frizijske rase (N=4833). Stanje dobrobiti na svakoj od farmi procenjivano je na osnovu relavantnih pokazatelja koji ukazuju na stepen obezbeđenja odgovarajuće ishrane, uslova držanja, zdravlja i ponašanja kao osnovnih principa dobrobiti. Ukupan skor (0-100 poena) omogućio je konačnu kategorizaciju farmi u jednu od četiri kategorije stanja kvaliteta dobrobiti (nezadovoljavajuću, prihvatljivu, odgovarajuću i odličnu). Prema rezultatima istraživanja, jedna polovina farmi svrstana je u kategoriju prihvatljivog, a druga polovina farmi u kategoriju odgovarajućeg kvaliteta dobrobiti. Uslovi držanja su na većini farmi (63%) ocenjeni nezadovaljavajuće (≤20 poena) zbog loše higijene i diskomfora. Na više od trećine farmi krave su držane vezano tokom cele godine, što udruženo sa slabom primenom ispaše (17 dana/godini prosečno) značajno ograničava njihov komfor i slobodu kretanja. Ovo je svakako u vezi i sa niskom ocenom obezbeđenja odgovarajućeg ponašanja (32 poena), posebno kada je u pitanju mogućnost ispoljavanja njegovih prirodnih oblika (6.7 poena). Zdravstveno stanje u proseku je ocenjeno kao prihvatljivo, ali su visoka incidenca laminitisa (38%), otežanih telenja (4.2%) i mortalitet (6.7%) prepoznati kao glavni činioci rizika po dobrobit. Uobičajena praksa izvođenja obezrožavanja (79%) bez primene anestetika/analgetika na farmama u Srbiji uzrok je bola i stresa kod životinja. Prosečan skor celokupno ocenjene dobrobiti (2.5/5) ukazuje na potrebu za unapređenjem u svim segmentima obezbeđenja dobrobiti mlečnih krava, posebno menadžmenta i uslova držanja.

Three farms of dairy cows (A, B and C) were observed for health disorders of dairy cows and suckling calves. Farm A is farm with tied system of rearing, with 1100 cows, while farms B and C have 400 and 600 cows kept loose with outdoor pens, respectively. Data regarding welfare criteria of dairy cows (health, feeding, housing and behaviour) were collected and analysed through Protocol of Welfare Quality (2009). Health disorders of dairy cows and suckling calves were collected and statistically analysed by chi-square test (X2 test). Welfare of all of three dairy farms were assessed as acceptable, meaning that provided welfare conditions meet the minimum requirements of animals. Principle of provision of good health was rated as acceptable (≥20 points) on farm A, while on farms with loose system (B and C) overall health rated as excellent (≥80 points). Occurrence rate of reproductive, locomotor, skin and claws disorders and digestive and systemic disorders of dairy cows and calves up to 4 months old were very different between three farms (A, B, C) with X2-values of 2901.71, 252.02, 204.08, 1152.31 and 184.23 respectively; α (lt) 0.01). According presented data, it is obvious that the majority health problems were observed in tied system of rearing, on farm A, such as reproductive disorders and mastitis, as well as injuries and bad body score and lame cows. The most serious health problems of the calves were diarrhea and bronchopneumonia of different etiology., Tri farme muznih krava (A, B i C) su analizirane u pogledu zdravstvenih poremećaja i dobrobiti krava i teladi. Na farmi A je zastupljen vezani sistem držanja sa 1100 krava, dok se na farmama B i C sa 400 odnosno 600 grla, krave drže slobodno. Podaci o dobrobiti mlečnih krava (zdravlje, ishrana, smeštaj i ponašanje) su prikupljeni i analizirani primenom protokola za ocenu kvaliteta dobrobiti (Anon, 2009). Poremećaji zdravlja krava u laktaciji i teladi su prikupljeni i statistički analizirani hi-kvadrat testom (X2 test). Dobrobit na sve tri mlečnih farmi je ocenjena kao prihvatljiva jer zadovoljava minimalne zahteve životinja. Princip obezbeđenja dobrog zdravlja je ocenjen kao prihvatljiv (≥20 bodova) na farmi A, dok je na farmama sa slobodnim sistemom (B i C) ocenjen kao odlično (≥80 poena). Pojava reproduktivnih, lokomotornih, digestivnih i sistemskih poremećaja mlečnih krava i teladi do 4 meseca starosti se veoma razlikovala između tri farme različite veličine i sistema uzgoja, sa x2-vrednostima 2901,71, 252.02, 204.08 , 1152,31 i 184,23, redom (α (lt) 0,01). Prema iznetim podacima, češća pojava zdravstvenih problema je uočena u vezanom sistemu uzgoja, na farmi A, u pogledu reproduktivnih poremećaja, mastitisa, povreda, loše telesne kondicije i hromosti krava, kao i proliva i bronhopneumonija teladi različite etiologije.

The social rank refers to the relative position of an individual animal within the dominant hierarchy developed in a group. In rams, social rank is mostly associated with body mass, body size and body condition. However, although the body mass is generally considered as one of the main determinants of social rank, only few studies have been carried out for the purpose of associating of the social behavior and body development of these animals. Objective of this research was to determine how the ram body development measures relate to establishment of social hierarchy. Social rank was established using food competition test at the age of animals between 4 and 17 months. Testing was done on total of 20 male animals of which number 12 animals were selected for further testing (6 dominant and 6 submissive animals). Body mass and testicular circumferences were measured at the age of 4, 7, 12 and 18 months, and linear body measures were taken at the age of 12 and 18 months. Dominant males had higher body mass and greater testicular circumference. The social rank had no significant effect on linear body measures of rams, except for chest girth (P (lt) 0.05) in both control periods. Body mass was moderately to highly positively associated with studied body parameters. Significant positive correlations were established between body mass and body length (r=0.58; P (lt) 0.01), chest width (r=0.44; P (lt) 0.05), chest girth (r=0.65; P (lt) 0.01) and testicular circumference (r=0.62; P (lt) 0.01). Results obtained in this study indicate that it is justified to observe the body mass as one of the main determinants of social rank, as well as the possibility of earlier maturation of dominant animals., Socijalni rang se odnosi na relativnu poziciju individue unutar dominantne hijerarhije koja se razvija u grupi. Kod ovnova, socijalni rang se najviše povezuje sa telesnom masom, veličinom tela i telesnom kondicijom. Međutim, iako se telesna masa generalno smatra jednom od glavnih determinanti socijalnog ranga, malo je istraživanja sprovedeno u cilju povezivanja socijalnog ponašanja i telesne razvijenosti ovih životinja. Cilj ovog istraživanja bio je da se utvrdi na koju način se mere telesne razvijenosti ovnova odnose prema uspostavljanju socijalne hijerarhije. Socijalni rang utvrđen je pomoću testa kompeticije na hranu kada su životinje bile u uzrastu od 4 i 7 meseci. Testiranje je obavljeno na ukupno 20 muških grla od čega je za dalje ispitivanje odabrano 12 grla (6 dominantnih i 6 submisivnih). Telesna masa i obim testisa mereni su u uzrastu od 4, 7, 12 i 18 meseci, a linearne telesne mere su izmerene u uzrastu od 12 i 18 meseci. Dominantna grla su imala veću telesnu masu i veći obim testisa. Socijalni rang nije imao značajan uticaj na linearne telesne mere ovnova, izuzev na meru obima grudi (P (lt) 0,05) u oba kontrolna perioda. Telesna masa bila je umereno do visoko pozitivno povezana sa ispitivanim telesnim parametrima. Značajne pozitivne korelacije utvrđene su između telesne mase i dužine trupa (r=0,58; P (lt) 0,01), širine grudi (r=0,44; P (lt) 0,05), obima grudi (r=0,65; P (lt) 0,01) i obima testisa (r=0,62; P (lt) 0,01). Rezultati koji proizilaze iz ove studije ukazuju na opravdanost posmatranja mase tela kao jedne od glavnih determinanti socijalnog ranga, kao i na mogućnost ranijeg sazrevanja dominantnih jedinki.

In this paper are described the most important stressors in intensive sheep production on farms and pastures. Stressors on farms and pastures mostly originate from adverse housing conditions, improper zootechnical procedures, veterinary procedures (treatment, vaccinations, blood tests, surgery), animal husbandry procedures (labeling, weaning, grouping, shearing, shortening the tail, hoof care), unsuitable weather conditions (extreme heat and cold) and insufficient nutrition. The paper puts out special emphasis on the consideration of period of life in which sheep were subjected to additional loads and susceptible to effects of these stressors, such as birth, juvenile period, puberty, oestrus, advanced pregnancy, parturition and the puerperal period., U radu su opisani najznačajniji stresori ovaca u intenzivnim uslovima proizvodnje na farmama i pašnjacima. Stresori na farmama i pašnjacima najčešće potiču od nepovoljnih uslova smeštaja i držanja, nepravilnih postupaka odgajivača, veterinarskih postupaka (lečenja, vakcinacije, vađenja krvi, hirurške intervencije), zootehničkih postupaka (obeležavanje, odbijanje, grupisanje, šišanje, skraćivanje repa, obrada papaka), neodgovarajućih klimatskih uslova (ekstremna toplota i hladnoća) i neodgovarajuće ishrane. U radu se poseban akcenat stavlja na razmatranje perioda života u kojima su ovce podvrgnute delovanju dodatnih opterećenja i podložnije delovanju ovih stresora, kao što su rođenje, juvenilni period, pubertet, estrus, visoki graviditet, porođaj i puerperalni period.

Agriculture of the Republic of Serbia is going through significant reforms in legislation and agricultural policy, during this EU preaccession period, in order to comply to one of the most important EU policies - Common Agricultural Policy (CAP). The potential and tradition of Serbia in production of beef, on one hand and EU market needs on the other, impose the need for timely preparations from the legislative and technological aspect and human resources. Present study gives the review of major legislative regulations and main parameters of SEUROP beef classification system in sense of definition, presentation and categorization of carcass, as well as criteria in conformation evaluation and fat cover of the carcass., Poljoprivreda Srbije u pretpristupnom periodu EU, prolazi kroz značajne reforme zakonodavstva i agrarne politike kako bi se prilagodila jednoj od najznačajnijih EU politika- Zajedničkoj poljoprivrednoj politici. Potencijal i tradicija naše zemlje u proizvodnji junećeg mesa sa jedne i potrebe tržišta EU sa druge strane, nameću potrebu za blagovremenim obavljanjem priprema u zakonodavnom, tehničkom i kadrovskom smislu. SEUROP standard je koncipiran da omogući 'zajednički EU jezik' koji opisuje kvalitet junećih trupova kao i analitiku baze podataka o životinjama, rezultatima klasifikacije i cenama što je od velikog značaja za primenu različitih mera podrške na tržištu unije. Obzirom da ovaj sistem podržava isplatu odgajivačima prema kvalitetu trupova, ovo je i važan instrument kojim se podstiče rad na unapređenju genotipova, ishrane i tehnologije u govedarstvu. U radu je dat pregled najvažnijih zakonskih regulativa i osnovnih parametara SEUROP klasifikacije junećeg mesa u smislu definicije, prezentacije i kategorizacije trupa kao i kriterijuma u oceni konformacije i prekrivenosti trupa lojem.

The aim of this study was to find out is it possible to presume success of boars sperm cryopreservation, based on controlled exposure to heat stress and to investigate in vitro quality parameters of frozen/thawed sperm of previously selected 6 boars with good results (group 1) and 6 boars (group 2) with bad results on thermo resistance test (TT). In this investigation, ejaculates of 12 chosen of 75 AI boars (Landrace, Large White, Pietrain and Durock breeds) from SVC Velika Plana (Serbia) were used. Tolerance to heat stress was performed by Schaetz (1963) method. Ejaculates were extended with Androhep plus (1:1) and kept during 60 minutes on 41oC. In cryopreservation of boars semen Westendorf et al. (1975) method, modified by Bwanga et al. (1990). Very significant changes of progressive motility rate were observed after spermatozoa exposure to controlled thermal stress. High correlation coefficient of progressive motility rate of both groups of boars, but higher in group 2 for progressive motility rate after thawing and after heat stress treatment was established. Average progressive motility rate of all 12 boars did not differ before and after thawing. Presence of boars of all breeds represented in the SVC (Large White, Landrace, Duroc and Pietrain) in both quality groups confirms the assumption that suitability for cryopreservation of sperm is individual trait. According data analysis, sperm deep freezing success requires previous selection for potential donors, which have to be consider standard quality parameters testing and controlled stress exposure tests., Cilj rada je da se ustanovi da li moguće odrediti da li je sperma nerasta pogodna za krioprezervaciju da se na osnovu izlaganja spermatozioda kontrolisanom toplotnom stresu i da se ispitaju in vitro parametri kvaliteta odmrznutog semena dve grupe od po 6 nerastova čije je seme dobro (1. grupa) ili loše podnelo toplotni stres (2. grupa). U istraživanju su korišćeni ejakulati 12 od 75 nerastova rasa: landras, veliki jorkšir, pijetren i durok (L, J, P, D) iz SVC Velika Plana, odabranih na osnovu testa termorezistencije (TT) i svrstanih u dve kvalitetne grupe. Ispitivanje stepena termorezistencije ejakulata u razređenju Androhep-om plus 1:1 60 minuta na 41 oC, je izvedeno metodom po Schaetz-u (1963). Duboko zamrzavanje sperme odabranih nerastova izvedeno modifikovanim postupkom po Westendorf-u i sar. (1975) i Bwanga-i i sar. (1990). Rezultati TT ukazali su na vrlo značajne promene progresivne pokretljivosti spermatozoida posle izlaganja kontrolisanom toplotnom stresu. Ustanovljen je visok koeficijent korelacije kod obe grupe ali ipak nešto viši kod nerastova 2. grupe za odnos procenta progresivne pokretljivosti spermatozoida posle odmrzavanja i progresivne pokretljivosti posle izlaganja temperaturi od 41oC. Prosečna progresivna pokretljivost spermatozoida svih ispitivanih nerastova se nije značajno razlikovala pre i posle zamrzavanja. Slučajni raspored nerastova svih rasa zastupljenih u SVC (Jorkšir, Landras, Durok i Pijetren) u obe kvalitetne grupe potvrđuje pretpostavku da je pogodnost sperme za krioprezervaciju individualna osobina. Za uspešnu krioprezervaciju sperme nerastova je neophodna prethodna selekcija potencijalnih donora na osnovu rezultata ispitivanja standardnih parametara kvaliteta i testova u kojima se spermatozoidi in vitro izlažu različitim kontrolisanom stresu.

The effects of general and special biosecurity measures to prevent introduction of infectious agents in a dairy farm or its spreading from farm were analyzed in details in this paper. Investigations were conducted on five different dairy farm production with different technology and capacity using a questionnaire method (Hristov and Stanković, 2009), as well as scrutinizing their positions in relation to possible sources bio-risks from the near and far away environment. Test results showed that there are serious shortcomings on all observed farms, regarding the possibility of introduction of infectious agents in the production herd, and its possible spread to the environment. Although all fenced and a position of the most of the farms mostly favourable, there are some serious threats to the herd health and farm production, regarding open space and lack of green belt, the uncontrolled presence of wild birds and rodents in facilities and even in feed storage, as well as contact of the employees with other cows not belonging to the farm., U radu su detaljno analizirani efekti preduzetih opštih i posebnih mera biosigurnosti koji se odnose na sprečavanje unošenja infektivnog materijala u farmu muznih krava ili njegovog širenja sa farme. Ispitivanja su obavljena na 5 farmi muznih krava različite tehnologije proizvodnje i kapaciteta metodom upitnika (Hristov i Stanković, 2009), kao i sagledavanjem položaja farme u odnosu na moguće izvore biorizika u bližoj i daljoj okolini. Rezultati ispitivanja ukazuju da na svim posmatranim farmama postoje ozbiljni nedostaci u pogledu mogućnosti unošenja infektivnih agenasa u proizvodni zapat, ali i njegovog mogućeg širenja na okolinu. Iako su sve ograđene, a položaj većine ispitivanih farmi uglavnom povoljan, otvorenost prostora i nedostatak zelenog pojasa, nekontrolisano prisustvo divljih ptica i glodara u objektima za držanje krava pa čak i smeštaj hrane, kao i kontakt zaposlenih sa drugim govedima koja ne pripadaju farmi predstavljaju ozbiljnu pretnju po zdravstveno stanje zapata i proizvodnju farme.

This paper gives a detailed analysis of the applied biosecurity measures in the production of boar sperm at a swine reproduction center. Biosecurity indicators (existence of a written biosecurity plan, isolation, introduction of newly acquired animals into the herd, herd health, assessment of the personnel attitude towards equipment, traffic control, attitude towards visitors, feeding and watering control, manure management, disposal of dead animal carcasses, attitude towards other animals, rodents and birds control, sanitation) were viewed and evaluated by rating scale: (5) - excellent, (4) - very good, (3) - good, (2) - sufficient, (1) - insufficient, there are resources for improvement (0) - insufficient, with no resources for improvement. Obtained data were analyzed in the SWOT process, taking into account all the strengths, weaknesses, threats and opportunities for improving the biosecurity level. The situation in the center is rated as very good, with an average rating of 4.15. However, one disadvantage is serious and related to the boar facilities isolation possibilities, taking into account their location and the presence of two types of male breeding animals (boars and bulls) in the same location. Newly acquired breeding animals are purchased from various sources, but with a rigorous regime of control and not at the same time., U radu je detaljno analizirana primena biosigurnosnih mera u proizvodnji sperme nerastova u jednom centru za veštačko osemenjavanje svinja. Sagledani su i procenjeni svi indikatori biosigurnosti (postojanje pisanog plana biosigurnosti, izolacija, uvođenje novonabavljenih životinja u zapat, zdravstveni status zapata, ocena odnosa osoblja prema opremi, kontrola kretanja i prometa, odnos prema posetiocima, kontrola ishrane i vodosnabdevanja, izđubravanje, uklanjanje leševa uginulih životinja, odnos prema drugim životinjama na farmi, kontrola populacija glodara i ptica, sanitacija), i ocenjeni prema skali ocena: (5) - odličan, (4) - vrlo dobar, (3) - dobar, (2) - dovoljan, (1) - nedovoljan, ima resursa za poboljšanje, (0) nedovoljan, nema resursa za poboljšanje. U razmatranju rezultata primenjena je SWOT analiza i utvrđene prednosti, nedostaci, rizici i mogućnosti za podizanje nivoa biosigurnosti. Stanje u centru je ocenjeno kao vrlo dobro, uz prosečnu ocenu 4,15. Međutim, jedan nedostatak je veoma ozbiljan i odnosi se na mogućnost izolacije objekata, uzimajući u obzir njegovu lokaciju i prisustvo dve vrste muških priplodnih životinja (nerastova i bikova) na istoj lokaciji. Nove priplodne životinje se nabavljaju iz različitih izvora, ali uz rigorozan režim kontrole i ne u isto vreme. Svakako, izmeštanje objekata za držanje priplodnih nerastova na drugu bezbednu lokaciju predstavlja složen ali prioritetan zadatak, kojim bi se otklonile brojne pretnje po proizvodnju sperme.

Evaluation of conformation and fat cover of beef carcasses has great importance in modern systems of carcass quality evaluation. In this way, adequate price is achieved for every classified carcass side according to market demand. In this paper, the effect of experimental crossing of Domestic Simmental breed with Charolais and Limousine breed (N=96) on conformation and fat cover was investigated. Evaluation was carried out on the whole carcass and partially for certain parts of carcass according to special evaluation pattern/form (1-5). In regard to evaluation of carcass conformation, statistically significant differences (p (lt) 0,01) were established between crosses and Domestic Simmental breed. Crosses with Charolais achieved the highest score for conformation (3,94), the highest score for round conformation (3,77) and shoulder (4,06). Considerably more fat tissue on outside of the carcass was determined in Domestic Simmental breed (3,44) compared to crosses with Charolais (3,27). Presence of fat in pelvic cavity was more expressed in Charolais (3,34) and Limousine crosses (3,28), with better score for covering of kidneys (3,50 and 3,53) compared to Domestic breed (3,17)., Ocena konformacije i prekrivenosti junećih trupova lojem ima veliki značaj u savremenim sistemima ocene kvaliteta trupova. Na ovaj način postiže se odgovarajuća cena za svaku klasiranu polutku prema zahtevima potrošača. U ovom radu ispitivan je uticaj eksperimentalnog ukrštanja domaće simentalske rase sa šarole i limuzin rasom (N=96) na konformaciju i prekrivenost junećih trupova lojem. Ispitivanje je obuhvatilo ocenu pomenutih osobina na celim trupovima kao i parcijalno na određenim delovima trupova a prema odgovarajućoj linearnoj skali ocene (1-5). U odnosu na ocenu konformacije trupova utvrđene su statistički značajne razlike (p (lt) 0,01) između meleza i domaće simentalske rase. Melezi Šarolea postigli su najbolju ocenu konformacije trupova (3,94), konformacije buta (3,77) i plećki (4,06). Značajno više masnog tkiva na spoljašnjem delu trupa utvrđeno je kod domaće simentalske rase.(3,44) u poređenju sa melezima Šarolea (3,27). Prisustvo masti u karličnoj šupljini bilo je izraženije kod Šarole (3,34) i Limuzin meleza (3,28), sa boljom ocenom prekrivenosti bubrega (3,50 and 3,53) u odnosu na domaću simentalsku rasu (3,17).

The most significant welfare problems in dairy calves in intensive rearing conditions have been investigated in this paper. These problems mainly result from inadequate intake of colostrum (separation from the dam), inadequate ventilation (resulting in inappropriate airflow, low or high temperatures, high humidity and poor air quality), poor floor conditions (wet floor, without bedding), inadequate monitoring of health, exposure to pathogens causing respiratory and gastrointestinal disorders and occurrence of iron deficiency. In addition, on cattle farms in our country welfare problems in calves originate from continuous restocking (no 'all in - all out') and mixing calves from different sources, as well as insufficiently balanced solid food, insufficient access to water and generally poor response of farmer to health problems, especially necessary dietary changes. A special welfare problem is insufficient floor space allowance which results in calf's discomfort., U radu su istraženi najznačajniji problemi dobrobiti kod teladi u intenzivnim uslovima gajenja. Ovi problemi su uglavnom posledica neadekvatnog uzimanja kolostruma (odvajanja od majke), neadekvatne ventilacije (dovodi do neodgovarajućeg protoka vazduha, niske ili visoke temperature, visoke vlažnosti i lošeg kvaliteta vazduha), loših uslova poda (vlažan pod, pod bez prostirke), neadekvatnog praćenja zdravlja teladi od strane odgajivača, izloženosti patogenim mikroorganizmima koji izazivaju respiratorne i gastrointestinalne poremećaje i pojave nedostatka gvožđa. Pored toga, na farmama u našoj zemlji problemi dobrobiti kod teladi potiču od kontinuiranog korišćenja staja (ne 'sve unutra- sve napolje'), mešanja teladi iz različitih izvora, kao i od nedovoljno izbalansirane čvrste hrane, nedovoljnog pristupa vodi i generalno lošeg odgovora farmera na zdravstvene probleme teladi, a posebno neophodne promene u ishrani. Poseban problem dobrobiti teladi su nedovoljne površine individualnih boksova koje rezultiraju u neudobnosti teladi.

The subject of this research was to determine the effect of the housing system on quality of welfare of dairy cattle in Serbia. Study was realized on six farms, capacity of 30 to 900 cows, with loose and tie housing system. Assessment of the welfare quality parameters was done by using the Welfare Quality® Assessment Protocol for Cattle, 2009. Results of the research show that the welfare quality of dairy animals is under the significant effect of housing system, and that loose system has the advantage when it comes to comfort around resting, easy of movements and health condition of cows. Share of not lame cows (81%) and cows with no lesion (86%) was significantly higher (p (lt) 0.01) in loose system. Indicator values: duration of lying down movements (6.53 sec), lying down movements with collisions (18.7%) and lying outside lying area (28.4%) in tie system were significantly higher (p (lt) 0.01) compared to loose system indicating the inadequacy of the housing and lack of comfort. Analysis of indicators associated with cow hygiene (dirty legs and udder) and diseases (dystocia) points to significant gaps in management in both housing systems which represent significant threat to cow welfare quality., Predmet ovog istraživanja bilo je utvrđivanje uticaja sistema držanja na kvalitet dobrobiti mlečnih krava u Srbiji. Ispitivanje je obavljeno na šest farmi, kapaciteta od 30 do 900 krava, sa slobodnim i vezanim sistemom držanja. Ocena parametara kvaliteta dobrobiti obavljena je korišćenjem Welfare Quality® Assesment Protocol for Cattle, 2009. Rezultati istraživanja pokazuju da se kvalitet dobrobiti mlečnih krava nalazi pod značajnim uticajem sistema držanja kao i da slobodni sistem ima prednost kada su u pitanju udobnost/komfor tokom /ležanja, lakoća kretanja i zdravstveno stanje krava. Udeo krava bez znakova šepavosti (81%) i krava bez lezija/povreda (86%) bio je signifikantno veći (p (lt) 0.01) u slobodnom sistemu. Vrednosti indikatora: pokreti krave tokom leganja (6.53 sec), pokreti krave tokom leganja gde dolazi do kolizije sa drugim grlima (18.7%) i ležanje izvan površina za ležanje (28.4%) u vezanom sistemu su signifikantno veće (p (lt) 0.01) u odnosu na slobodni i ukazuju na neadekvatnost smeštaja i nedostatak komfora. Analiza indikatora vezanih za higijenu krava (prljave noge i vime) i bolesti (distocia) ukazuje na značajne propuste menadžmenta u oba sistema držanja, koji ozbiljno ugrožavaju kvalitet dobrobiti krava.

Preservation of necessary level of swine herd health status is the most important aspect of bio-security, farm production and successful welfare protection. It involves a list of bio-security measures which must be essential part of production technology, including good rearing conditions and other prophylactic measures appliance. According to previously performed investigations, a list of elements required to establish standards for bio-security for particular pig farm was created. The list includes elements related to assure spatial., microclimate and hygienic conditions for pigs rearing, care, nutrition and watering, surveillance, regrouping and transport of swine, disease outbreak control, barns equipment and production process organization which are performed by veterinarians and zootechnicians. Bio-security standards must concern necessary level of swine herd health status and organization, size and type of operation and anticipate all compulsory measures for health control and disease spreading prevention, particularly those whose outbreak must be reported. In bio-security plan structure present epidemiological situation, potential herd health and production threats, as well as possible solutions must be concerned., Očuvanje potrebnog nivoa zdravstvenog stanja populacije je najvažniji aspekt očuvanja biosigurnosti i uspeha proizvodnje, kao i dobrobiti svinja, i podrazumeva niz biosigurnosnih mera koje moraju biti sastavni deo proizvodne tehnologije, uključujući dobre uslove smeštaja i držanja i primenu profilaktičkih mera. Na osnovu sprovedenih istraživanja je sastavljena lista elemenata neophodnih za uspostavljanje standarda i izradu planova biosigurnosti za konkretnu farmu svinja. Lista sadrži elemente koji se odnose na obezbeđenja prostornih, mikroklimatskih i higijenskih uslova gajenja životinja, negu, ishranu i napajanje, nadzor, pregrupisavanje i transport životinja, mera za sprečavanje pojave bolesti, opremanje staja i organizacija tehnološkog procesa proizvodnje, koje sprovode odgajivači, veterinarski i zootehnički stručnjaci. Standardi biosigurnosti moraju uzeti u obzir neophodan nivo zdravstvenog stanja zapata svinja, organizaciju, obim i vid proizvodnje na farmi i predvideti sve neophodne mere za kontrolu zdravstvenog stanja zapata i sprečavanje unošenja i širenja infektivnih bolesti, posebno onih čije se postojanje mora prijaviti. Pri izradi konkretnih planova biosigurnosti mora se uzeti u obzir trenutna epizootiološka situacija, ali i predvideti potencijalne pretnje po zdravstveno stanje i proizvodnju na farmi i moguća rešenja.
