褪黑激素对獭兔生长性能及皮毛质量的影响
Effects of Melatonin on Growth Performance and Fur Quality of Rex Rabbits
摘要
Abstract
A single-factor experiment was designed to study the effect of melatonin on growth performance and fur quality of Rex rabbits.A total of 200 healthy growing Rex rabbits at the age of 55 to 60 days with similar body weight were randomly divided into 4 groups with 50 rabbits per group.Rex rabbits in the control group were fed a basal diet, and the others in the experimental groups were fed the diets which concluded different levels of melatonin (10, 25 and 40 mg/kg, respectively).The experiment lasted for 99 days.The results showed that at 60 to 150 days of age, the average daily gain of experimental groups was significantly higher than that of control group (P<0.01), the ratio of feed to gain of experimental groups was significantly lower than that of control group (P<0.01).At 90, 120, 130 and 150 days of age, the hair density of experimental groups was significantly higher than that of control group (P<0.01).The pelt thickness in buttocks, shoulder and belly of 40 mg/kg experimental group was significantly lower than that of control group (P<0.05 or P<0.01).The results showed that melatonin can improve the average weight gain of Rex rabbits, reduce the ratio of feed to gain, and at the same time increase hair density, which is helpful to the skin of early maturity.[Chi关键词
