| 摘 要： | 降低料肉比，可以在饲喂量一定时多生产猪肉，提高生猪生长速度，既减少生产成本，又提高利润。本研究在配方发酵生物饲料的基础上，采用单因素试验和响应面中试优化，获得继续降低料肉比饲料饲养最佳优化参数为日粮赖氨酸10 g+蛋氨酸5 g、日饮小分子活性水用量1.0 L、日粮生物有机硒（以Se计）1.5 mg+维生素E 150 mg、日粮柠檬酸14 g，可将料肉比降低至2.4161：1，较大幅度降低了饲养成本，显著增加了利润。不仅如此，从试验饲喂开始到结束，没有一头试验猪患过疾病，表现抗病性强、精神好、食欲旺盛、皮毛油光发亮、猪肉鲜香，提高了养猪场和养猪户的收入和养猪抗风险能力。

| Abstract: | Reducing the feed-to-meat ratio can produce more pork when the amount of feed is given,and increase the growth rate of pigs,which not only reduces the production cost of pigs,but also increases the profit of pigs.On the basis of formula fermentation biological feed,single factor test and response surface pilot test optimization were adopted to obtain the optimal parameters for feeding feed with continuous reduction of feed meat ratio,including dietary lysine 10 g+methionine 5 g,daily dosage of small molecule active water consumption 1.0 L,diet biological organic selenium concentrations of 1.5 mg+VE 150 mg,diet citric acid 14 mg,the ratio of feed to meat could be reduced to 2.4161:1,which greatly reduced the cost of raising pigs and significantly increased the profit of raising pigs.Not only that,from the beginning to the end of the experimental feeding,none of the experimental pigs had any disease,and showed strong disease resistance,good spirit,good appetite,fur shiny and smooth,pork fresh fragrance,increased the income of pig farmers and the ability of pigs to resist risks. |
