Abstract:

The effects of pasteurized colostrum on growth performance and development of the gastrointestinal tract of calves were studied in this test. Twenty healthy newborn Holstein calves with similar body weight were randomly divided into two groups. The calves in control group were fed non-pasteurized colostrum while that in experimental group were fed on pasteurized colostrum. The experiment lasted for 90 days. The body weight,average body gain (ADG),average daily feed intake (ADFI),F/G and diarrhea rate were determined and at 0,30,60 and 90 days old,the body indexes were measured. The results showed that compared with control group,the ADFI and ADG of calves at 90 days old in experimental group were increased 1.74% and 2.33% (P> 0.05),and cannon circumference and body length were increased 2.68% and 1.41% (P> 0.05),while the diarrhea rate and F/G were decreased 0.67% and 2.40% (P> 0.05).There was no significant effect of pasteurized colostrum on the complex stomach weight,small intestine weight and small intestine length (P> 0.05). However,the ratio of complex stomach weight to body weight in control group was significantly higher than that of experimental group (P< 0.05). In conlusion,the pasteurized colostrum had a positive impact on growth performance for calves in 90 days old.
