饲料油菜FTMR的羔羊强度育肥效果研究
|
摘要
为研究饲料油菜发酵全混合日粮(FTMR)的羔羊强度育肥效果,本试验选取2.5月龄的湖羊40只,随机分为2组,每组20只,公母各半。试验组饲喂以油菜为主原料配制的FTMR日粮,对照组饲喂以青贮玉米为主原料配制的TMR日粮。预试期15 d后称初试体重,正式期90 d,每15 d称重,记录采食量,计算平均日增重。结果表明:湖羊母羊采食量、体重和日增重在两种日粮间无显著差异(P> 0.05);而试验组公羊采食量显著高于对照组(P <0.05),75 d后体重和日增重都显著高于对照组(P <0.05)。根据日增重、采食量、饲料成本、活羊价格计算育肥收益,油菜FTMR日粮育肥湖羊公羊和母羊的收益都高于对照组。因此,饲料油菜FTMR日粮用于羔羊强度育肥效果较好。
This study aimed to explore the effect of forage rape on growth performance in lamb intensive finishing.A total of 40 Hu sheep aged at 2.5 months were randomly divided into two groups,each group had 10 males and 10 females.The sheep were raised in four pens.The sheep of the experiment group were fed with fermented total mixed ration(FTMR) which was mainly made from forage rape while that of the control group were fed with TMR which was mainly made from silage corn.The experiment lasted 90 days after 15 preliminary feeding.The body weight was measured every 15 days,and the feed intake was recorded.The results showed that there was no significant difference of feed intake,body weight and average daily gain between the experiment group and the control group in ewes.However,compared with the control group,the feed intake in the experimental group was incerased(P < 0.05),and the body weight,average daily gain were increased significantly after 75 days.The profit based on average daily gain,feed intake,feed cost and sheep price was calculated.The profit of the finishing ewes and rams fed with FTMR was higher than sheep fed with TMR,especially better for rams.All the results indicated that FTMR which was mainly made from forage rape may be good to intensive finishing lamb.
