Effects of Milk Replacer on Growth Performance and Plasma Biochemical Indices of Qianbeima Lambs
摘要
Abstract
This study was conducted to evaluate the effects of milk replacer on growth performance and plasma biochemical indices of Qianbeima lambs. Forty healthy lambs with similar body weight were randomly assigned to 4 groups with 10 lambs in each group. Lambs in control group and groups 1, 2 and 3 were 1 of 4 diets diffe-ring in milk replacer level at 0, 2%, 4% and 6%, respectively. The results showed as follows:1) the supple-mentation of milk replacer significantly increased dry matter intake ( supplemented at 2% to 6%) , and apparent digestibility of dry matter ( supplemented at 4%) , crude protein ( supplemented at 4%) , neutral detergent fiber ( supplemented at 2% to 6%) , acid detergent fiber ( supplemented at 2% to 6%) , ash ( supplemented at 2%and 4%) in diet, as well as absorbed nitrogen ( supplemented at 2% to 6%) , retained nitrogen ( supplemented at 4%) , digestibility of nitrogen( supplemented at 4%) , net protein utilization ( supplemented at 4%) and bio-logical value of nitrogen ( supplemented at 4%) ( P<0.05);2) The supplementation of 4% and 6% milk re-placer significantly increased average daily gain ( P<0.05) , and reduced feed to gain ratio ( P<0.05) . 3) The data of whole period showed that the supplementation of 4% milk replacer significantly increased total anti-oxi-dative capacity and the activities of superoxide dismutase, catalase and lysozyme ( P<0.05) , and decreased the contents of malondialdehyde and urinary nitrogen ( P<0.05) , but had no effects on glucose content and the ac-tivities of glutathion peroxidase and alkaline phosphatase in plasma ( P>0.05) . The results indicate that dietary supplementation of milk replacer can improve average daily gain, nutrient digestibility, reduce feed to gain rati-o, and was beneficial for protein efficiency, plasma anti-oxidative capacity and immunity improvements for Qianbeima lambs. Overall, it is suggested that the supplemental level of 4% shows the best performance under the conditions in the present study.关键词
