Effects of Different Fatty Acid Sources in Milk Replacer on Growth Performance, Digestion and Metabolism of Sucking Calves
摘要
Abstract
The objective of study was to determine the effects of butterfat replaced by coconut oil or palm oil in milk replacer on growth performance, digestion and metabolism of sucking calves. Sixty newborn Holstein calves were randomly assigned to one of five groups. Calves in different groups were fed five isonitrogen and isoenergetic replacers with different butterfat sources,which were as follows:1)butterfat as sole fat sources in milk replacer;2)50% butterfat was replaced by coconut oil;3)100% butterfat was replaced by coconut oil;4)50% butterfat was replaced by palm oil;5)100% butterfat was replaced by palm oil. The trial lasted for 56 days. The results showed as follows:1)at 14 to 56 days of age,the replacement of coconut oil or palm oil at 50% or 100% did not significantly affect average daily gain, dry matter intake, feed efficiency, and diarrhea rate(P>0.05);2)serum total cholesterol,triglycerides,high density lipoprotein cholesterol,low density lip-oprotein cholesterol and free fatty acid contents were not significant affected by the replacement of coconut oil or palm oil at 50% or 100%(P>0.05);3)the apparent digestibility of dry matter, organic matter, ether ex-tract, calcium and phosphorus, and energy utilization rate were not significant affected by the replacement of coconut oil or palm oil at 50% or 100%(P>0.05). The change of fatty acid composition by replacement of butterfat by coconut oil and palm oil in milk replacer has little effect on growth performance,digestion and me-tabolism of nutrients of sucking calves.关键词
