摘　　要：研究在相同营养水平下不同水平膨化血粉对雏鹅生产性能和营养物质表观代谢率的影响。试验选用300只健康、活泼的1日龄豁眼鹅,公母各半,体质量(78.68±2.95)g,随机分为3组:膨化血粉1.5%组、3.0%组和4.5%组,每组设5个重复,每个重复20只鹅,试验时间28 d。结果表明,膨化血粉3.0%组效果最好,与膨化血粉1.5%、4.5%组相比,平均雏鹅日增体质量分别提高9.40%、13.27%(P<0.05),料重比分别降低3.69%、2.34%(P<0.05),CP、ME的表观代谢率分别提高3.30%和3.08%、1.95%和2.46%(P<0.05)。在该研究条件下,建议雏鹅日粮中膨化血粉的适宜添加比例为3.0%。The objectives of the present study were to investigate effects of different Levels of expanded blood meal on production performance and apparent metabolic rate in gosling.Three hundred 1-day-old Huoyan geese with(78.68±2.95)g body weight(female∶male=1∶1) were randomLy assigned into 3 groups,5 replications each group,20 geese each replication.1.5%,3.0% and 4.5% expanded blood meal were added to the 3 groups respictively at the same trophic level.The experiment lasted 28 days.The results indicated that the best effects were achieved by 3.0% expanded blood meal diet.Compared with 1.5% group and 4.5% group,the average weight gain(ADG) in 3.0% group was separately improved 9.40% and 13.27%(P<0.05),the feed to gain ratio(F/G) in 3.0% group was separately decreased 3.69% and 2.34%(P<0.05),the apparent metabolic rate of CP,ME in 3.0% group was separately improved 3.30%,3.08%,1.95% and 2.46%(P<0.05).It is suggested that the optimal supplementation of expanded blood meal in the gosling diets be 3.0%.
