Uzgoj i othrana podmlatka predstavlja jedan od najvažnijih razdoblja u govedarskoj proizvodnji. Teladi je potrebno osigurati najbolje moguće uvjete života te voditi računa i o njihovom zdravstvenom stanju. Temeljem proizvodnih, zdravstvenih i ekonomskih učinaka othrane na punomasnom mlijeku do različite starosne dobi u pokusu je sudjelovalo 30 teladi Holstein pasmine. Telad je raspoređena u tri skupine po deset životinja, a vrijeme trajanja pokusa je 60 dana. Telad skupine I konzumirala je punomasno mlijeko do 30.dana, telad skupine II do 20.dana a telad skupine III do 10. dana. Do kraja pokusa sva su telad hranjena mliječnom zamjenicom. Kroz pokusno razdoblje na teladi u pokusu praćeni su osnovni tovni pokazatelji (tjelesna masa, prosječan dnevni prirast, konverzija iskorištenja tekuće hrane), učestalost proljeva te izračuna cijene kilograma prirasta po skupinama. Dobiveni rezultati tjelesne mase, dnevnog prirasta i konverzije tekuće hrane teladi, pokazali su najbolje vrijednosti kod teladi I skupine. Rezultati zdravstvenog stanja ogledan kroz učestalos pojave probavnih poremećaja, pojave proljeva, dodatno potvrđuju i pozitivan zdravstveni učinak kod teladi u skupini I. I na ovaj način se potvrđuje prioritet mlijeka u odnosu na mliječnu zamjenicu. Nižom cijenom prirasta dokazana je i ekonomska opravdanost upotrebe punomasnog mlijeka., Growing and, nutrition is one of the most important parts of cattle production. Calves is the need to ensure the best possible conditions of life and lead a major concern for the state of health. Based on production, health and economic impacts nursed the whole milk to different age groups in an experiment involving 30 Holstein calves. Calves is distributed in three groups of ten animals and the duration of the experiment was 60 days. Calves Group I consumed the whole milk to 30 days following, calves Group II to the 20. On the calves of group III to 10 the. By the end of the experiment all the calves fed milk replacer. Through trial of calves was monitored by analyzing fattening indicators, the incidence of diarrhea and price calculation pounds of gain per group. The results of body weight, daily weight gain and conversion of liquid feed calves, showed the best values in calves and groups. Results health status Viewed frequency with the occurrence of digestive disorders, diarrhea, further confirmed by the positive health effects in calves in group I, and in this way confirms the priority of milk compared to milk replacer. Lower price growth was demonstrated and economic justification for the use of whole milk.

Važnost pravilne tehnologije uzgoja teladi proizlazi iz izravnog utjecaja na proizvodna i reproduktivna svojstva te vijek eksploatacije odrasle životinje, a kako je tekuća komponenta najskuplja hrana, važan je i ekonomski učinak uzgoja. S ciljem da se usporedi proizvodni, zdravstveni i ekonomski učinak uzgoja teladi na punomasnom mlijeku do različite dobi, proveden je praktični dio istraživanja na 30 teladi holstein pasmine. Telad je raspoređena u tri skupine (10 životinja u skupini), a razdoblje pokusa obuhvaćalo je vrijeme od teljenja do 60. dana. Telad I. skupine konzumirala je punomasno mlijeko do 30. dana, telad II. skupine do 20. dana, a telad treće skupine do 10. dana. Potom su do 60. dana svi konzumirali mliječnu zamjenicu. Učinak predloženih tehnoloških rješenja othrane teladi u pokusu analiziran je praćenjem osnovnih tovnih pokazatelja te učestalosti pojave proljeva, kao i izračunom vrijednosti cijene kilograma prirasta po skupinama. Rezultati statističke obrade tjelesne mase, dnevnog prirasta i konverzije tekuće hrane teladi tijekom prvog mjeseca pokusa pokazali su najbolje vrijednosti kod teladi I. skupine, što je bilo statistički visoko signifikantno (P, Determination of correct feeding regimes for calves is very important as it directly influences calves’ productive and reproductive traits, as well as duration of adult animal exploitation period. As the liquid feed is the most expensive component, its importance also has an economic aspect in calves rearing. The experiment was carried out on 30 Holstein calves with the aim to determine productive, economic and health effects of feeding calves with whole milk in different periods. Calves were divided into three equal groups (10 calves in each group). Experiment was carried out in the period from calving up to the 60th day of calf ’s age. All groups were given whole milk, however, duration of whole milk feeding differed among groups. Group 1 consumed whole milk from birth up to the 30th day of age, group 2 from birth up to the 20th day of age and group 3 from birth up to the 10th day of age. Afterwards, all groups were fed with milk replacement formula up to the 60th day of age. Suggested technological solutions in calves feeding within this experiment were analyzed through evaluation of basic fattening characteristics, monitoring of diarrhea occurrences and calculating costs per kg of weight gain per each group. Statistical analysis referring to calves body weight, daily gain and liquid feed conversion during the 1st month of experiment proved the best values for group 1, which were statistically highly significant (P
