本试验旨在分析和测定全粒木薯的常规养分及其生长猪消化能(DE) 、代谢能(ME) 。试验选用体重为(51.9±1.8) kg的“杜×长×大”三元杂交健康去势公猪12头,采用交叉设计并分配3种饲粮。饲粮设计采取等比回归法,包括1组玉米-豆粕型基础饲粮和2组由全粒木薯分别等比替代15%、30%基础饲粮的试验饲粮,所有饲粮中除待测原料外,其余能量原料间均保持着相同的比例;回归过程以全粒木薯摄入量为回归因子,对生长猪DE、ME摄入量作回归方程,进而得到全粒木薯生长猪DE、ME。结果表明: 1)全粒木薯总能为15.02 MJ/kg,干物质含量为88.58%,粗蛋白质含量为2.62%,粗脂肪含量为0.62%,粗纤维含量为17.66%,粗灰分含量为...

The digestible energy ( DE) , metabolizable energy ( ME) of full cassava pellet for growing pigs were determined using regression method. Twelve " Duroc×Landrance×Large White" castrate male pigs with an initial body weight of ( 51. 9 ± 1.8) kg were allotted to one crossing﹣over experiment design in which as﹣signed to 3 diets. There were 3 diets in each experiment consisting of a corn﹣soybean meal basal diet and 2 test diets. The test diets consisted of each of the 2 full cassava pellet samples that partly replaced the basal diet at 15% or...
