过瘤胃脂肪对林麝体重、血液指标和产香性能的影响
Effects of Rumen Protected Fat on Body Weight,Blood Indexes and Musk Production Performance of Forest Musk Deer
摘要
Abstract
This experiment was conducted to investigate the effects of diet supplemented with rumen protected fat on body weight,blood indexes and musk production performance of forest musk deer.Sixty-three healthy male musk deer[body weight:(8.0±0.5)kg]aged 2 to 10 years old were divided into 7 groups with 9 repli-cates per group and 1 musk deer per replicate.The control group(group A)was fed the basal diet,and the ex-perimental groups were fed the basal diet supplemented with 4(group B1,short-term),4(group B2,long-term),8(group C1,short-term),8(group C2,long-term),12(group D1,short-term)and 12 g/d(group D2,long-term)rumen protected fat,respectively.The experiment lasted for 121 days in the short term groups(groups B1,C1 and D1)and 195 days in the control group and long term groups(groups B2,C2 and D2),containing a 15-day pre-trial period.The results showed as follows:1)at the end of the experiment,the body weight of forest musk deer in each experimental group was higher than that in the control group,but the difference was not significant(P＞0.05).2)The dry weight of musk in group C2 was increased significantly with the control group and groups B1,B2 and D2(P＜0.05),but there were no significant effects on the fresh weight,the contents of moisture and musk ketone of musk(P＞0.05).3)There were no significant differences in the contents of serum insulin,testosterone,total protein,albumin,triglyceride,total cholesterol,glucose and urea among all groups(P＞0.05).Serum non-esterified fatty acids(NEFA)content in groups B2,C1,D1 and D2 were significantly decreased compared with the control group(P＜0.05).In conclusion,under the condition of this experiment,diet long-term supplemented with 8 g/d rumen protected fat can increase the body weight and dry musk yield of forest musk deer.[Chinese Journal of Animal Nutrition,2025,37(2):1210-1220]关键词
