本试验研究了用木薯皮粉(CPM)替代玉米对生长猪的屠体、器官和病理特性的影响。选用24头16周龄长白×大白猪，分别饲喂CPM替代玉米的0、10、20和30%水平的4种试验日粮。日粮等氮等能，CP含量为16%，MJME为12.08MJME/kg。每种饲料被喂给一组六头猪。结果表明，随着日粮中CPM水平的提高，屠体重量和背脂厚度降低。心脏、肾脏、肝脏和脾的重量(以体重百分比表示)在CPM含量为30%的水平上显著较高。同样，饲喂30%CPM饲料的猪的肾脏表现出肾小管的变性、坏死和扩张。同一只猪的肝脏出现胆管扩张、纤维化和小叶间隔增厚。试验结果表明，CPM可替代生长猪日粮中玉米含量的20%，且对猪的屠体、器官和病理特性无不良影响。《农业科学》2005年第4卷(1)：第1-4页
An experiment was conducted to investigate the effects of replacing maize with Cassava Peel Meal (CPM) on the carcass, organ and pathological characteristics of growing pigs. Twenty-four 16-week old pigs of Landrace x Large White breed were raised on four experimental diets where CPM replaced maize at 0, 10, 20 and 30 percent levels. The diets were formulated to be isonitrogenous and isoenergetic containing 16 % CP and 12.08 MJME/kg. Each diet was fed to a group of six pigs. Results indicated that carcass weight and backfat thickness decreased as level of CPM in the diets increased. Heart, Kidney, Liver and Spleen weights (expressed as percentage of body weight) were significantly higher at the 30 percent level of CPM inclusion. Likewise, Kidney of pigs fed the 30 percent CPM diet showed degeneration, necrosis and dilatation of the tubules. Liver of same pigs had bile duct dilatation, fibrosis and thickening of the interlobular septa. It was concluded that 20 percent of the maize content of the diets of grower pigs can be replaced by CPM without any deleterious effect on the carcass, organ and pathological characteristics.
