摘要
随机选取20头约克夏哺乳母猪,按胎次配对随机分成2个处理,每个处理10个重复,分别饲喂可消化赖氨酸水平为0.95%(A组)和1.05%(B组)的2种日粮,考察不同氨基酸水平的哺乳母猪日粮对母猪和仔猪生产性能的影响。试验结果表明:①与A组相比,B组母猪的生产性能没有明显提高;②与A组相比,B组仔猪的初生重、断奶重和日增重分别提高了5.40%(P<0.05)、16.57%(P<0.05)和19.76%(P<0.05)。因此,哺乳母猪日粮中赖氨酸水平的适当提高能显著提高仔猪的生产性能。
A single factor design was conducted to explore the effects of the level of lysine at 2 doses on sow and piglet performances. 20 sows from Yorkshire breed were randomly divided in-to 2 treatments. The level of digestible lysine was set to 0.95% （group A） and 1.05% （group B） respectively. Results showed that the higher dietary digestible lysine level （group B） do not have significant effect on the performance of sow, but it increased significantly the birth weight, weaned weight and ADG （P〈0.05） of piglet with an increase of 5.40%, 16.57% and 19.76% re-spectively. In conclusion, the increased digestible lysine （1.05%） in lactation diets could im-prove the performance of piglet significantly.
