提高稻壳粉饲用价值研究

A Study on Improving the Feed Value of Ground Rice Husk

根据稻壳粉的化学特性和育肥猪生长营养需要特点，研究以含粗纤维４０％的稻壳粉为基础饲料原料，加入“５１８”添加剂预混料，平衡其营养成分，提高了其饲用价值，使育肥猪日增重达６２０ｇ，料肉比为４９５∶１，增重１ｋｇ耗饲料成本为２０８元，取得了较好的社会效益和经济效益。

The feed resource based on ground rice husk with a crude fiber content of 40% was studied. Through adding in additive premix 518, its nutrient contents were in equilibrium and its nutritive value was improved. So the daily liveweight gain of growing finishing pigs was up to 620 g, the feed conversion efficiency was 4.95∶1 and the cost of feed consumption was 2.08 yuan per 1 kg liveweight gain.
