湖羊羔羊早期断乳(7日龄)后代乳粉饲喂效果研究
Study on milk replacer for early weaning (7-day old) Hu sheep lambs
摘要
Abstract
The experimental early weaning (7-day old) Hu sheep lambs were randomly divided into groups of A and B and they were feeding with milk replacer A and B for 38 days,correspondingly.Milk replacer A contains high crude protein and high crude fat,and milk replacer B contains high crude protein and medium crude fat.Results showed that the average daily gain of the lambs in group A with feeding of replacer A for 1-45 days was not significantly (＞0.05) lower than that in the control group A1,while the average daily gain of the lambs in experimental group A with feeding of replacer A for 30-40 days was significant higher than that in control group A1.In group B,the average daily gain of the lambs was significantly (P＜0.05) lower than that in the control group B1.As regard to body measurements,the height of the lambs in A and B had no significant difference (P＞0.05) compared to those in the control groups of A1 and B1.At 20 days of age,the chest girth,body length and cannon circumference of the lambs in experimental group B were significantly (＜0.05) lower than those in the control group B1.At 30 days of age,the chest girth of the lambs in experimental group A and B was significantly (P＜0.05) lower than that in the control group A1 and B1,respectively.The measurement results showed that the growth speed of the lamb body in experimental group A was quicker than that in experimental group B,but the turning point where the growth speed was falling occurred later than that in experimental group B.The result indicated that milk replacer A is better than milk replacer B for the growth of early weaning (7-day old) Husheep lambs.关键词
