饲草型全混合日粮对羔羊增重、屠宰性能及经济效益的影响
|
摘要
为了研究饲草型全混合日粮对羔羊增重、屠宰性能及经济效益的影响,试验选取小尾寒羊与乌珠穆沁羊杂交一代6月龄公羊28只,分为6个处理组和1个对照组,每组4只羊,分别饲喂不同配方的饲草型全混合日粮和对照日粮,进行为期63 d的饲喂试验,测定和统计了初始体重、终末体重、总增重、宰前活重、胴体重、屠宰率、总采食量、日采食量、日增重、日粮单价、日投入、日利润。结果表明:处理4组的饲喂效果最好,总增重、宰前活重、胴体重、屠宰率分别达到了15.20 kg、45.35 kg、24.75 kg和54.58%,日采食量、日增重、日投入和日利润分别为1.54 kg/只、0.24 kg/只、3.04元/只和0.60元/只。说明紫花苜蓿、燕麦草、玉米胚芽粕、玉米秸秆、酒糟蛋白饲料(DDGS)和天然牧草按照20%、20%、24%、6%、24%、6%的比例混合饲喂羔羊,增重效果明显,屠宰性能最佳,经济效益最大。
In the experiment, twenty eight 6-month-old rams were selected from the hybrid generation of Han sheep and Wuzhumuqin sheep, and they were divided into 6 treatment groups and 1 control group(CK), with 4 sheep each, which were fed with different formulas of TMR diet and control diet. Feeding tests were conducted for a total of 63 days. The initial weight, final weight, total weight gain, live weight before slaughter, carcass weight, slaughter rate, total feed intake, daily average feed intake, daily average weight gain, unit price of diet, daily average input and daily average profit were measured.The results showed that the group 4 had the best feeding effect. The total weight gain, live weight before slaughter, carcass weight and slaughter rate reached 15.20 kg,45.35 kg,24.75 kg and 54.58% respectively. The average daily intake, average daily gain, average daily input and average daily profit were 1.54 kg, 0.24 kg, 3.04 yuan and 0.60 yuan,respectively. It indicates that when alfalfa, oat grass, corn germ meal, corn straw, legume protein feed(DDGS) and natural pasture are mixed in a ratio of 20%, 20%, 24%, 6%, 24%,and 6%, the weight gain,slaughter performance,economic benefits effect are best.
