1、配制仔豬15-35kg的配方思路：一、根據(jù)仔豬體重的查看飼養(yǎng)標(biāo)準(zhǔn)如下：肉脂型生長育肥豬的營養(yǎng)需要量(表一)飼料需要項(xiàng)目單位體重階段10—2020—35 預(yù)期日增重g420.00500.00能量需要采食風(fēng)干料kg0.911.60消化能MJ12.6012.97消化能Mcal3.014.96代謝能MJ12.1012.05代謝能Mcal2.894.77蛋白質(zhì)需要粗蛋白質(zhì)g173.00160.00賴氨酸g7.106.40蛋+胱氨酸g4.604.20蘇氨酸g4.604.10異亮氨酸g5.004.60礦物質(zhì)需要Cag5.805.50P
