| 摘 要： | 试验研究 3种营养需要模式对 8～ 2 0kg断奶仔猪生产性能、胴体品质和胴体瘦肉生长的影响。结果表明 ,采用建议的营养需要模式配制的饲粮饲养仔猪 ,获得的生产性能、胴体品质、胴体瘦肉增重和无脂瘦肉增重以及胴体瘦肉成分优于或接近于采用NRC( 1998)营养需要模式配制的饲粮、极显著优于采用中国 ( 1987)营养需要模式配制的饲粮。根据本试验结果认为 ,建议的营养需要模式更适合杜× (大×长 )断奶仔猪的需要。

Effect of Three Nutrient Requirement Patterns on the Performance, Carcass Traits and Lean Meat Gain of Weanling Piglets |

| Abstract: | Sixteen 7-day-old goslings were randomly allotted to control and enzyme treated groups.The diet contained 45% barley and it was added 0.1% Biokyowa enzyme preparation for treatment group in experimental phase(7～21 day).At day 21,the goslings were slaughtered and the intestinal chyme samples were collected for determining.The results are as follow:In control group,the viscosities of intestinal chyme were increased significant from duodenum to ileum.The pH of chyme between duodenum and jejunum was not significant (P>0.05).The viscosity of ileal chyme was higher than those of duodenum and jejunum by 17.61%(P<0.01)and 37.15%(P<0.01),separately.Also the pH of duodenal chyme was lower than those of jejunum and ileum by 0.75%(P>0.05)and 5.92%(P>0.05).In treatment group,the viscosity of intestinal chymes had same tendency as that of the control,the viscosity of duodenal,jejunal and ileal chyme were lower by 17.61%(P<0.01),37.15%(P<0.01)and 59.46%(P<0.01)than those of control,separately.Whereas the pH of duodenum,jejunum and ileum were lower than that of control by 4.21%,4.18% and 3.79%(P>0.05).These results show that enzyme preparation can affect the characteristics of intestinal chyme by relief the anti\|nutritional action of β-glucan in barley ,so that to improve the rice\|bran based diet reverse rate and benefit quick growth of gosling. |
