摘　　要：为了探讨饲料不同粉碎粒度对育肥猪生产性能的影响,于4个代养场分别选取30、72、20、20头健康育肥猪进行了4轮同一日粮不同粉碎粒度(1.5和2.5 mm)的饲喂试验,试验组育肥猪饲喂平均粉碎粒度为1.5 mm的日粮,对照组育肥猪饲喂平均粉碎粒度为2.5 mm的日粮,试验期分别为22、30、36、43 d,测定分析了育肥猪的生产性能。结果显示:用平均粉碎粒度为1.5 mm的日粮饲喂22 d的试验组育肥猪料肉比增加,为负效应;饲喂30 d和36 d时料肉比降低,为正效应;饲喂43 d时料肉比显著降低,为显著正效应。说明饲料粉碎粒度影响育肥猪料肉比,但其应用效果与持续使用时间有关。In order to study the effects of feed particle size on the performance of fattening pigs,30,72,20 and20 healthy fattening pigs were fed with four rounds of the same diet with different feed particle sizes(1.5 mm and2.5 mm),the fattening pigs in the test group were fed diets with an average feed particle sizes of 1.5 mm and the control group were fed diets with an average feed particle size of 2.5 mm for 22,30,36 days and 43 days,respectively.The results showed that the feed-meat ratio of fattening pigs fed a diet with an average feed particle size of 1.5 mm for 22 days was negative,the feed-meat ratio of fattening pigs fed 30 days and 36 days was positive,and the feed-meat ratio of fattening pigs fed 43 days was significantly lower,for a significant positive effect.The results showed that the feed particle size affected the feed-meat ratio of fattening pigs,but the application effect was related to the duration of use.
