摘要
研究表明笼养肉鸡的鸡粪中粗蛋白含量比平面养的高１６．４７个百分点，而粗纤维低９．１２个百分点。用鸡粪喂猪，其饲料报酬同加入鸡粪的比例呈正相关，如日粮中添加３０－６０％鸡粪，其饲料报酬提高１５．３２－５５．３２％；同样加入４０％鸡粪喂猪，鸡粪经发酵的饲料报酬又比不发酵的高９．６２％。为使育肥猪得到较好的增重，还应将日粮的营养水平调整到接近饲养标准，猪鸡联养规模，一个专业户一次批量以肉鸡１０００－１５００羽，联养生猪１０－２０头为宜。
The results
of experement research showed that the contents of crudeprotein and crude fiber of the fowls
excrement from cage rearing were higher and lowerby 16.47%and 9. 12%,respectively,than that
from plat rearing. The feed conversionwas positive related to the content of fowls excrement in
diet. Additiving 30%-60%offowls excrement to diet increased the feed conversion bv l5.32%-55.
32%. At the 40%of fowls excrement in diet,the feed coversion was increased 9.62%by
fermentation offeed.The level of nutrition in the diet ought to be exchanged to the standar of
feeding.Appropriate united raising scale was 1000-1500 fowls and 10-20 pigs.
