摘要
选择体重６５千克左右的杜洛克×大约克×长白杂种肥育猪１８０头，随机分配到三个饲粮营养水平，在炎热环境（白天平均温度２７．８２℃）饲养。结果表明，在炎热环境条件下，采用含３．２兆卡消化能／千克、１６％粗蛋白、０．７９％赖氨酸的饲粮饲养，可取得较好的生产性能和经济效益。
One hundred and eighty cross-bred pigs weighing 65kg each of Duroc×Yorkshire×Landrace were selected and allotted at random to three levels of dietary nutrient to be fed in a hot ambience(average temperature is 27.82℃ in daytime). The experiment result showed that better production performance and economic benefit could be obtained in hot ambience by using diet containing 32 Mcal DE/kg, CP of 16% and lysine of 0. 79%.
