Effect Of Different Proteins In Milk Replaces On Healthy Growth And Weaning Of Calves

The purpose of study is to compare the effect of Different Proteins in Milk Replaces on Healthy growth and weaning of Calves.Total of 72 Hostein dairy calves were randomly divided into three groups. Body weight and size were detected at d 0,11,25 39 and 60 after birth. According to the standard of weaning is daily intake exceeds 900 g during three days, the weaning ages were recorded. The fece scores were done everyday. The results showed that the weight when born in different treatment is not significant difference. The weights of calves in control are higher than other two treatment (P<0.01) at age of d 60, but weights in MR-P are higher than MR-M (P<0.05). The body height from three treatment are not different significantly. The chest circumference from control is larger than other two treatments (P<0.01). The intake of one week from MR-P and MR-M is higher than control from d 53 to 60. Weaning age of calves from plant protein treatment is not different to milk protein treatment (P>0.05). Before weaning, the fece score of MR-P is higher than MR-M (P<0.05). Althrough there was no significant effect of different proteins in milk replaces on the production of calves, plant protein led to higher rate of diarrhea.
