Effects of dietary soybean phosphatides on performance and blood biochemical parameters in lactating cows
摘要
Abstract
The experiment was conducted to study the effect of dietary soybean phosphatides on the performance, metabolic parameters, blood biochemical parameters and the optimal dose of soybean phosphatide of dairy cows during early lactatation. Eight primiparous healthly Holstein cows were selected in a replicated 4×4 Latin square design, and assigned randomly into 4 groups each with 2 replicates. The treatments were the diets with 0% , 1% , 2% or 3% soybean phosphatide ( DM basis) , respectively. The results showed that dietary soybean phosphatide level did not affect dry matter intake ( DMI) (P>0. 05) , but increased the feed efficiency, significantly in the group of 2% soybean phosphatides ( P<0. 05). Compared with the control group, the milk yield, 4% FCM, daily milk fat yield and daily milk protein yield in the group of 2% soybean phosphatides were also significantly increased ( P<0. 05 ). However, milk composition and somatic cell count ( SCC) were similar among groups (P>0. 05). Diets with 3% soybean phosphatides significantly decreased the apparent digestibility of ADF ( P<0. 05) and extremely increased serum triglyceride levels ( P<0. 01). Therefore, soybean phosphatide supplementation in diets could improve milk performance, health status, immunity function and feeding profit. The optimal dose of soybean phosphatide in diets was 2% ( DM basis).关键词
