Abstract :

The aim of this experiment, evaluated effects of the use of milk replacer compared to cow's milk on health, weight gain, dry matter consumption and blood metabolites. In this study, 20 male and female calves Holstein (average weight 42 ± 4.2) in a completely randomized design were tested. In this experiment two treatments were used, which included a treatment group were tested to milk replacer and received treatment, including two control groups who received cow's milk. Both treatments until day 21 milk cows were fed only with a treatment from day 21 until a lactation milk substitute can be used and treatment 2 (control) after 21 days of taking milk to cow milk were using. The results showed that significant differences in daily gain among treatments were observed, but in terms of numerical treatment 2 slightly higher. Among the amount of blood metabolites in blood globulin calf milk substitute that had consumed significantly higher (0/0099s Pr> F) TNEFA treatment that a successor had consumed milk, close to significant level than the control group was lower (0/087ns Pr> F), other metabolites in blood, a significant difference between treatments did not exist. Between treatments daily dry matter intake was not significant, but the number of calves that had replaced milk consumption was higher. (733 grams compared to 728 grams).
