摘要
研究了日粮中菊苣鲜草与配合饲料的比例对鹅生长发育以及养殖经济效益的影响。结果显示:饲养21日龄鹅6周后,对照组(菊苣∶饲料=0∶1)鹅的增重率显著高于各试验组(P<0.05),试验组1(菊苣∶饲料=4∶1)与试验组2(菊苣∶饲料=8∶1)之间差异不显著;对照组的胸宽、龙骨长和胫围显著大于试验组2(P<0.05),各组之间其他体尺指标差异不显著;各组之间鹅的肌胃指数、总肠长、小肠长和盲肠长呈现显著差异(P<0.05),其他内脏指标差异不显著;试验组2的养殖经济效益最高。建议鹅日粮中菊苣与饲料的比例为(4~8)∶1。
This experiment was conducted to study the effects of different chicory and formula feed ratios in the diet on the growth and cultivation benefit of goose.The results indicated that: after six weeks' rearing of 21-day-old goose,the weight gain rate of goose in the control group(chicory∶formula feed=0∶1) was significantly higher than that in various test groups(P0.05),while test group 1(chicory∶formula feed=4∶1) and test group 2(chicory∶formula feed=8∶1) had no significant difference in goose weight gain rate.Breast width,keel length and shank girth of goose in the control group were significantly higher than those in test group 2(P 0.05),and other body-size indexes in each group was not significantly different.Gizzard index,total intestinal length,small intestine length and cecum length appeared significant difference among various groups(P0.05),and other gut indexes had no significant difference.The rearing economic benefit of test group 2 came to the highest among different groups.We suggested that the suitable chicory and formula feed ratio in the diet was between 4∶1 and 8∶1.
