三种蛋白质饲料对雏鹅生产性能和表观代谢率的比较研究   摘要:选用300只健康、活泼的1日龄豁眼鹅(Anser cygnoides Linn. var domestica cv. Wulong),公母各半,体重78.68 g±2.95 g,随机分为3组,分别是添加血粉3.0%组、膨化血粉3.0%组和鱼粉3.0%组,每组5个重复,每重复20只雏鹅,试验期28 d。研究在相同营养水平条件下,相同比例的血粉、膨化血粉以及鱼粉对雏鹅生产性能和营养物质表观代谢率的影响,以及膨化血粉替代鱼粉的可行性。结果表明,与血粉组相比,膨化血粉组与鱼粉组的料重比分别降低了13.28%、14.11%(P<0.05),平均日增重分别提高了18.65%、19.99%(P<0.05),营养物质中性洗涤纤维、酸性洗涤纤维、粗脂肪、粗蛋白质、钙及能量的表观代谢率显著提高,其中粗蛋白质的表观代谢率提高幅度较大,分别为7.45%、8.25%(P<0.05),但膨化血粉组和鱼粉组间差异不显著(P>0.05)。说明饲养效果以鱼粉组最好,膨化血粉组次之,血粉组最差;以3 %的膨化血粉等比例替代鱼粉在雏鹅日粮中是可行的。   关键词:雏鹅;膨化血粉;生产性能;表观代谢率   中图分类号:S835.4+5;S816.48文献标识码:A文章编号:0439-8114(2011)04-0790-04      Comparative Study on Production Performance and Apparent Metabolic Rate of Three Protein-feed Diets in Gosling      ZHANG Hai-tang1a,LIU Chang-zhong1a,CUI Jian-xun2,LI Guo-ming3,WANG Zi-liang1a,WANG Shu-yun1b   (1.

Wulong) with body weight of (78.68±2.95)g (females∶male=1∶1) were randomly assigned into 3 groups and each group with 5 replications. 3.0% blood meal, 3.0% expanded blood meal and 3.0% fish meal were added to the 3 groups respectively at the same nutrient level to study the apparent metabolic rate of different protein-feed diet and their effects on the production performance and to investigate the feasibility of the expanded blood meal on goose. Compared with the 3.0% blood meal group, the F/G in 3.0% expanded blood meal group and 3.0% fish meal group decreased by 13.28% and 14.11% (P<0.05) respectively, and average daily gain increased by 18.65% and 19.99% (P<0.05) respectively, the apparent metabolic rate of NDF、ADF、EE、CP、Ca、ME were significantly higher. The apparent metabolic rate of CP in the two groups were 7.45% and 8.25
