摘  要：
本试验为研究以青刈黑麦为纤维原料的大体积日粮对母猪繁殖性能的影响而设计。以消化试验测定青刈黑麦草粉的数据为基础 ,配制粗纤维含量依次为 3.65% ,7.69%和 11.9% 3种日粮处理 ,其主要营养物质日采食量相同。不同日粮处理对总产仔数、产活仔数、出生窝重、2 1d窝重、断奶窝重和断奶仔数的影响均不显著。从仔猪 2 1d窝增重来看 ,处理 2组比对照组和处理 1组约高 10 %。处理 2组仔猪的生后生长速度相对提高。总之 ,青刈黑麦草粉大体积日粮粗纤维水平在 12 %左右时 ,对繁殖性能无不利影响

摘  要：
A feeding trial was conducted to determine the effect of feeding forage rye hay based diets on the reproductive performance of Duroc sows.Three diets were formulated on the basis of major nutrients contents of forage rye hay measured by the digestible trial.The crude fibre contents were 3.65%(control), 7.69%(treatment 1) and 11.90% (treatment 2) respectively in these three diets. The daily feed intake of the main nutrients was almost the same for the three diets. The effect of the different diets were not signifficantly different on total number of piglets born, number of piglets born alive, the litter weight at farrowing , litter weight at 21d after farrowing, litter weight at weaning and the number of piglets weaned. The value of the litter weight gain at 21d in treatment 2 group was 10% higher than that in control and treatment 1 group. The litter weight gain in treatment 2 was relatively improved. It could be concluded that there was no negative effect on the reproductive performance for sows if the crude fibre level was increased to about 12% in the diet containing forage rye hay.
