摘要 本研究旨在探索不同处理和不同品种鹅对玉米干酒糟及其可溶物(DDGS)真代谢能(TME)和常规养分的利用率。试验分别选取150日龄健康五龙鹅(小型)和青农灰鹅(大型)公鹅各24只,各设4个处理,每个处理6只。处理1直接强饲玉米DDGS,处理2强饲玉米DDGS并添加微量元素、维生素,处理3强饲玉米DDGS并添加玉米淀粉,处理4强饲玉米DDGS并添加玉米淀粉、微量元素、维生素。试鹅单笼饲养,每天强饲120 g,采用全收粪法测定真代谢能和养分利用率。结果表明:五龙鹅、青农灰鹅品种内4个处理之间TME,粗蛋白质(CP)、粗脂肪(EE)、氨基酸(AA)、酸性洗涤纤维(ADF)、中性洗涤纤维(NDF)、粗纤维(CF)、钙(Ca)、磷(P)利用率差异均不显著(P>0.05);处理1、4的青农灰鹅TME极显著高于五龙鹅(P<0.01),处理4的青农灰鹅CP利用率为70.81%,显著高于五龙鹅(P<0.05),处理3的青农灰鹅EE利用率也极显著高于五龙鹅(P<0.01);处理1、2、4的五龙鹅NDF利用率显著(P<0.05)或极显著(P<0.01)高于青农灰鹅,处理2、3、4的五龙鹅ADF利用率也显著(P<0.05)或极显著(P<0.01)高于青农灰鹅,4个处理的五龙鹅CF利用率均显著高于青农灰鹅(P<0.05)。结果提示,鹅对玉米DDGS的养分有较高的利用率,同品种不同处理下鹅对玉米DDGS的TME、常规养分利用率差异均不显著,不同品种的鹅对玉米DDGS的养分利用率存在一定差异。 The study was conducted to explore the true metabolic energy(TME) and the availability of conventional nutrients of corn distillers dried grains with solubles(DDGS) for Qingnonghui geese and Wulong geese with different treatments.For each breed,twenty four healthy male geese at the age of 150 d were selected,and were divided into 4 treatments with 6 replicates each and 1 goose in each replicate.Geese in treatment 1 were forced fed corn DDGS,treatment 2 were forced fed corn DDGS with microelements and vitamins,treatment 3 were forced fed corn DDGS with cornstarch,and treatment 4 were forced fed corn DDGS with microelements,vitamins and cornstarch.The goose was raised in a single cage individually and forced fed 120 g of feed every day.All feces were collected to determine the TME and the availability of nutrients of corn DDGS.The results showed that no significant differences were found in the TME and the availability of CP,EE,AA,ADF,NDF,CF,Ca and P among the 4 treatments of each breed(P0.05).However,the TME of Qingnonghui geese in treatments 1 and 4 were significantly higher than that of Wulong geese(P0.01).The availability of CP of Qingnonghui geese in treatment 4(70.81%) was significantly higher than that of Wulong geese(P0.05),and the availability of EE of Qingnonghui geese in treatment 3 was significantly higher than that of Wulong geese(P0.01).The availability of NDF of Wulong geese in treatments 1,2 and 4 was significantly higher than that of Qingnonghui geese(P0.05 or P0.01),the availability of ADF in treatments was 2,3 and 4 was significantly higher than that of Qingnonghui geese(P0.05 or P0.01),and the availability of CF in each treatment of Wulong geese was significantly higher than that of Qingnonghui geese(P0.05).The results suggest that the corn DDGS has a very high efficiency of nutrients utilization for geese.No significant differences in the TME,the availability of nutrients of corn DDGS is found within the same breed of geese,but some differences in the availability of some nutrients of corn DDGS still occur between different breeds of geese.
