The effect different milk replacer on the production characteristics of calves

Abstract

Provedeno je istraživanje s ciljem usporedbe mliječnih zamjenica različite hranjive i energetske vrijednosti. Pokus je proveden na 51 teletu holstein pasmine ženskog spola podijeljenih u kontrolnu i pokusnu skupinu u trajanju od 59 dana. Tijekom pokusa praćeni su tjelesna masa i utrošak mliječne zamjenice te su na osnovu dobivenih rezultata izračunate vrijednosti prosječne tjelesne mase, prosječni dnevni prirast i konverzija mliječne zamjenice. Dobivene vrijednosti prosječne tjelesne mase na kraju pokusa bile su više kod kontrolne skupine kao i vrijednosti prosječnog dnevnog prirasta, statistički značajnih razlika nije bilo. Konverzija mliječne zamjenice bila je niža kod pokusne skupine.A study was carried out to compare milk replacer of different nutrition and energy values. The experiment was performed on 51 female holstein female breeds divided into a control and experimental group for 59 days. During the experiment, the body mass and the consumption of the milk substitute were monitored and on the basis of the obtained results the average body weight, mean daily growth and conversion of the milk substitute were calculated. The mean body mass values obtained at the end of the experiment were higher in the control group than in the mean daily value increase, statistically significant differences were not observed. The conversion of dairy vice was lower in the experimental group
