摘要
选择 90头母猪 ,随机分为 3组 ,每组 30头 ,分别饲喂含 4% ,6 %及 8%粗纤维的饲粮 ,以探讨不同纤维水平对母猪繁殖性能的影响。试验表明 ,含 6 %纤维的饲粮组与含 4%纤维的饲粮组相比 ,前者显著提高了母猪产仔数 ,但各组间仔猪初生重无显著差异。不同的饲粮纤维水平对母猪及仔猪的血清生化指标没有明显影响。
Ninety sows were randomly divided into three groups with 30 sows in each to study the effects of different levels of fiber in the diet on their reproductive performance. The sows were fed with diets containing 4, 6 and 8% of fiber. Compared with the diet with 4% fiber, the diet containing 6% fiber improved litter size at birth. No significant differences were observed in the experiment for birth weight of the piglets. Fiber level in the diet did not seem to influence the serum biochemical parameters of the gestating sows and their piglets, either.
