摘　　要：本研究旨在探究山羊日粮中添加不同比例啤酒糟对育肥山羊生长性能、血清生化指标、屠宰性能和肉品质的影响。随机选取24只身体状况良好、体质量相近的3月龄简州大耳羊羯羊,分为4组,分别饲喂添加0、42.90%、48.00%、53.00%啤酒糟的日粮。试验周期为70 d,其中预饲期14 d,正式期为56 d。结果表明,与对照相比,在日粮中添加48.00%啤酒糟处理的山羊只均经济利润显著提高,并且该处理对血清生化指标、屠宰性能和内脏指标无不利影响,还在一定水平上改善了山羊肉品质。综上所述,本研究条件下,在简州大耳羊羯羊日粮中添加啤酒糟的最适比例为48.00%。The aim of this study was to investigate the effects of different proportions of brewer’s grains on growth performance,serum biochemical indices,slaughter performance and meat quality of fattening goats.Twenty-four 3-month-old Jianzhou Da’er goats with good body condition and similar body weight were divided into four groups and fed with diets supplemented with 0,42.90%,48.00%and 53.00%brewer’s grains,respectively.The experiment lasted for 70 days,with a pre-feeding period of 14 days and a formal period of 56 days.The results showed that compared with the control,the average economic profit per goat was significantly increased by adding 48.00%brewer’s grains to the diet.This treatment had no adverse effects on serum biochemical indices,slaughter performance,and visceral indices,and improved the meat quality of goats to a certain extent.In conclusion,under the conditions of this study,the optimum proportion of brewer’s grains added to the feed of Jianzhou Da’er goat was 48.00%.
