Rapeseed is the most widely used oil crop in Europe and it is an ideal raw material for the production of biodiesel. Because of a high nutritional value and a relatively high omega-3 fatty acids content, rapeseed cake can be used in poultry nutrition for the enrichment of meat and eggs. Therefore, the aim of this study was to determine the possibility of using rapeseed cake in diets for turkeys for the purpose of enriching turkey meat with omega-3 fatty acids. In the study, 120 male day-old Nicholas 700 turkeys were used and randomly divided into 3 groups, each group with 4 replications (n= 10). The control groups of turkeys were fed on compound feed without rapeseed cake and the experimental groups were fed with 5 or 10% share of rapeseed cake in compound feed. Based on the results obtained, we can conclude that the share of rapeseed cake of 5 or 10% in the compound feed did not cause any adverse impact on the performance of turkeys. Also, we established that there was an increase of the amount of omega-3 fatty acids with increased share of rapeseed cake and there was a positive trend of a decrease of the ratio of omega-6/omega-3 polyunsaturated fatty acids. Positive financial effect of fattening can be expected, because rapeseed cake is a cheaper source of protein in comparison with the commonly used soybean meal. Therefore, rapeseed cake can be recommended in fattening of hybrid turkeys, with a share up to 10% in the compound feed.

Upotreba pogače uljane repice već godinama predstavlja veliki izazov istraživačima i nutricionistima glede njenih udjela u krmnim smjesama za različite kategorije peradi. Cilj ovog istraživanja bio je utvrditi utjecaj 0, 5 i 10 % pogače uljane repice (domaćeg kultivara Bristol) u krmnim smjesama na proizvodna svojstva 120 Nicholas muških purana podijeljenih u 12 skupina do dobi od 9 tjedana. Završne tjelesne mase iznosile su 6598, 72, 6701, 25 i 6510, 53 g, gledano po tretmanima. Udio pogače uljane repice od 5 % doveo je do značajno (p0.05) signifikantne. Konverzija krmne smjese na kraju istraživanja (redoslijedom po tretmanima) iznosila je 2.52, 2.33 i 2.26, dok je mortalitet purana bio 2.5, 0 i 5 %. Iz svega gore navedenoga vidljivo je da se pogača uljane repice može preporučiti u udjelu od 5 % u krmnim smjesama za tov hibridnih purana.

Hrvatsko peradarstvo ima dugu tradiciju i solidnu sadašnjost te dobru podlogu za razvitak, a obuhvaća gotovo sve vidove proizvodnje kao što su: uzgoj i držanje rasplodnih nesilica hibrida teških pasmina, valionice, tov pilića, purića, pačića i guščića, klaonice peradi, uzgoj i držanje rasplodnih nesilica hibrida lakih pasmina, uzgoj konzumnih nesilica i proizvodnju konzumnih jaja, sortirnice, te tvornice stočne hrane. Pozicija peradarstva unutar cjelokupnog stočarstva Hrvatske glede zadovoljavanja vlastitih potreba i pokrića uvoza izvozom je vodeća. U radu je prvenstveno analizirano kretanje broja peradi, proizvodnje i potrošnje peradarskih proizvoda, te izvoza i uvoza. U razdoblju poslije 1991. godine broj peradi u Hrvatskoj se u prosjeku smanjivao 3, 1 %, proizvodnja prirasta peradi 0, 6 %, a proizvodnja kokošjih jaja 1, 2 % prosječno godišnje. Tijekom analiziranog razdoblja saldo trgovinske bilance peradarskih proizvoda RH bio je pozitivan, s izuzetkom 2002. godine. Vrijednost izvoza peradarskih proizvoda povećavala se 3, 7 %, a vrijednost uvoza 5, 3 % prosječno godišnje. U ukupnoj vrijednosti izvoza peradarskih proizvoda najveći udio činile su prerađevine na bazi mesa peradi, a u vrijednosti uvoza rasplodni materijal. Osnovni problemi s kojima se susreće naše peradarstvo su dosta različiti, a proizlaze iz dva segmenta istog: nekoliko krupnih subjekata koji posluju na razini cijele Hrvatske i u inozemstvu na jednoj strani, te veliki broj malih obiteljskih gospodarstava lokalnog značaja. Veliki proizvođači mesa peradi i jaja bore se s osuvremenjivanjem tehnologije, sve većom konkurencijom i općim gospodarskim uvjetima u Hrvatskoj, a obiteljska gospodarstva uz prije navedeno i s udovoljavanjem brojnim zakonskim domaćim i EU propisima, kao i s neujednačenošću proizvodnih kapaciteta, nabavnim cijenama, uvjetima plaćanja, nesigurnim tržištem itd. Uzevši u obzir opći svjetski trend rasta peradarske proizvodnje i hrvatsko peradarstvo ima dobre izglede za razvoj i širenje, pa i manji broj sitnih obiteljskih gospodarstava u sektoru organsko biološke proizvodnje novih prepoznatljivih proizvoda na bazi naših domaći vrsta i pasmina peradi.

Cilj istraživanja bio je usporediti učinkovitost restriktivne hranidbe u ljetnim mjesecima uz dodatak Bio-Mos-a na proizvodne rezultate tovnih pilića gledanih preko ostvarenih tjelesnih masa, konverzije krmnih smjesa i mortaliteta. 360 (Cobb 500) jednodnevnih (muških + ženskih) pilića slučajnim je izborom podijeljeno u dvanaest skupina po 30 pilića. Istraživanje je trajalo 38 dana i bilo je podijeljeno u dvije faze: 1. faza od 1. do 18. dana i 2. faza od 19. do 38. dana, a tijekom istraživanja pilići su konzumirali krmne smjese starter (21, 80 % s.b.) i finišer (18, 83 % s.b). Hranidbeni tretman tijekom istraživanja bio je slijedeći: četiri skupine (K) bez tretmana, četiri skupine (P) s restrikcijom hrane u 4. tjednu od 25% i u 5. tjednu od 20% u odnosu na (K) i četiri skupine (PBM) s istim tretmanom kao i (P) uz dodatak Bio-Mos-a, 2.0 kg/t (0-18 dana) i 1.0 kg/t (19-38 dana). Prosječne tjelesne mase u dobi pilića od 38 dana iznosile su 2.52, 2.27 i 2.35 kg. Konverzija hrane je u istraživanom periodu iznosila ; 1.77, 1.74 i 1.70 kg/kg. Mortalitet je iznosio 7.5, 5 i 1.7 %. Pilići kontolne skupine ostvarili su očekivano najbolje (p>0.05) tjelesne mase, no pilići iz skupine (PBM) imali su najbolju konverziju hrane i najniži postotak mortaliteta, što opravdava restriktivnu hranidbu te korištenje Bio-Mos-a, poglavito tijekom ljetnih mjeseci.

Zagorje turkey became known in Croatia during the past four and a half centuries. The content of total fat and composition of fatty acids in breast muscle (m.pectoralis superficialis) were measured in Zagorje turkeys from free range rearing and free choice feeding. 144 young turkeys were divided into two groups (C and E), each comprising of 72 birds (36 males+ 36 females). For the first four weeks turkeys were fed a starter diet (25% protein), then grower diet (23% protein) for the next four weeks. From week 9 to 24 of age turkeys were free choice fed whole corn grain (C) or grounded corn (E) plus soybean meal with vitamin-mineral mix. At the same time birds grazed on pasture. Total lipids and fatty acids composition of breast meat of 10 samples (5 male+5 female) were analyzed. Absolute values of majority of fatty acids in the experimental birds are similar to those in commercial hybrid turkeys. Level of decosahexaenoic (C22:6n3) acid was for approximately 100% higher in breast muscles of female Zagorje turkeys, when compared to commercial hybrids. Effect of sex and treatment on level of n-3 polyunsaturated fatty acids was established in breast of Zagorje turkeys.

The aim of this research was to investigate the effect of free-choice feeding and feed restriction on the performance of 302 free-range Zagorje turkeys, divided into two control (male C1 and female C2) and two experimental (male E1 and female E2) groups. First four weeks turkeys were fed a starter diet (24.2% CP) and the next four weeks grower (21.8% CP). In the following 4-month period turkeys were grazing on pastures with supplemental free-choice corn and soybean meal with vitamin-mineral premix. The level of nutrition of the experimental groups was 30% lower than in groups C1 and C2. The body weight of turkeys on the end of experiment was: C1-5853.8, C2-3391.9, E1-6010.6 and E2-3323.4 g. FCR over the whole 4-month period was 6.53, 7.50, 5.05 and 6.40. Ratio of corn: soybean meal consumed was similar, ranging from 1:0.46-1:0.48. Mortality was 3.84, 0.00, 2.56 and 3.84 %. Dressing percentage was 73.2, 70.5, 72.4 and 71.4 %.

The subject of this research is the nutritive effect that different quantities (10 and 20%) of dried olive cake had on total proteins and the proportion of individual proteins, on triacylglycerols, on total cholesterol, HDL and glucose in the serum of fattened rabbits following a 56-day experiment. The experiment involved 60 rabbits, divided into three groups: a control group (C) and two test groups (E1 and E2), each comprising 10 males and 10 females. Throughout the experiment, rabbits in group C received no olive cake in their feed; group E1 rabbits were fed a feed mixture containing 10% of dried olive cake; group E2 rabbits received a feed mixture containing 20% of dried olive cake. After the 56th day of the experiment, blood samples were obtained by cardiac puncture, and specific heamatological variables, total proteins and their fractions, triglycerides, total cholesterol, HDL and glucose were established in the serum. The results obtained show no significant differences in the concentration of total proteins, albumin, alpha1, alpha2, beta and gamma globulin in the serum of rabbits in control group and in the two test groups. Similarly, no significant differences were found in the concentration of serum triacylglycerols and glucose between group C rabbits and the two test groups. However, group E1 rabbits did show a significantly lower concentration of cholesterol compared with those in group E2; group E1 rabbits also had a significantly (P
