Abstract : |
The study was conducted to determine the effect of probiotic based on Lactobacillus sp. on performance and health status of Holstein male calves. 12 (3 days old) calves with average initial live weight 35 kg were assigned to the control and the group with probiotics applies. All calves were weaned at 60th day. Twice daily, during the time period till weaning they consumed 228 whole milk. Calves of probiotic group received 2 g probiotic daily with the morning milk. The results showed that there were no differences in daily gain, roughage, concentrate or total feed intake, feed to gain ratio and weaning weight. Calves fed with probiotic were healthier than the control calves. Three calves from control group and one calf from probiotic group were died from scour and/or bloat. In respect to diarrhea and bloat cases, probiotic group was superior to the control. It would be concluded that the probiotic administration before weaning could improve calves health and decrease mortality and veterinary cost. , The study was conducted to determine the effect of probiotic based on Lactobacillus sp. on performance and health status of Holstein male calves. 12 (3 days old) calves with average initial live weight 35 kg were assigned to the control and the group with probiotics applies.
