苎麻叶饲用效果及苎麻叶配制浓缩饲料的研究

苎麻叶按干物质计算含蛋白质在20%以上,可作各类畜禽的饲料,用鲜、干苎麻叶进行兔、鸡、猪的饲养试验表明,用鲜叶喂肉兔,其增重效果和饲料报酬优于牛皮菜和蕹菜;用占日粮4%和8%以上的苎麻叶干粉饲喂肉鸡和蛋鸡,对增重、性成熟和产蛋等均无不良影响;生长肥育猪的日粮中加入15%的苎麻叶粉,平均日增重和饲料消耗与对照组相近,用苎麻叶粉配制浓缩饲料喂生长肥育猪,平均日增重可达617～626 g,材肉比为3.27:1和3.48:1,优于普通配合饲料。

A STUDY ON THE FEEDING EFFECTS ANDCONCENTRATED FORAGE OF RAMIE LEAVES

Dry ramie leaves contain more than 20% protein which is available todomestic animals and poutry. The study shows that the weight-increasing andforage reward of pork rabbits fed with fresh ramie leaves are better than thosewith swamp cabbage and chard, no reverse effects exist in the weight-increas-ing, sex-maturing and egg-lay of chichen and hens fed with 4% or 8% ofdried ramie leaf powder in their daily feed, containing 15% of ramie leaf powderin the daily feed of porkers causes no difference from CK in mean daily weight-increasing and consumption ratio of forage and porkers fed with forage con-taining concentrated forage of ramie leaf powder gain daily 617~626 g inweight, produce 3.27:1 and 3.48:1 of stuff/pork ratios which are lower thanthose with common balanced forage.
