摘要
试验旨在研究青贮玉米混合型颗粒饲粮对籽鹅生长性能、屠宰性能、器官指数及血清生化指标的影响.试验选取28日龄籽鹅60只,随机分成2组,每组3个重复,每个重复10只鹅.对照组籽鹅饲喂基础饲粮,青贮组籽鹅饲喂青贮玉米混合型颗粒饲粮,试验期42 d.结果显示,两组籽鹅生长性能和器官指数无显著差异(P＞0.05);与对照组相比,青贮组籽鹅的半净膛率显著提高了 3.57％(P＜0.05),血清谷丙转氨酶活性显著降低了41.44％(P＜0.05).研究表明,在籽鹅育成期饲喂青贮玉米混合型颗粒饲粮对生长发育无负面影响,并有助于提高屠宰性能.
Abstract
The experiment aimed to study the effects of silage corn mixed pellet diet on the growth performance,slaughter traits,viscera indexes,and serum biochemical indexes of Zi geese.A total of 60 Zi geese at 28 days of age were randomly divided into two groups with three replicates in each group and 10 Zi geese in each replicate.Zi geese in the control group was fed a basal diet,while in silage group was fed the silage corn mixed pellet diet,with the experimental period of 42 days.The results showed that there was no significant difference in growth performance and viscera indexes between the two groups(P＞0.05).Compared with control group,Zi geese in the silage group semi-eviscerated rate significantly increased by 3.57％,and serum glutamic-pyruvic transaminase activity significantly decreased by 41.44％(P＜0.05).The study indicates that feeding silage corn mixed pellet diet in the Zi goose breeding period has no negative effects on growth and development,and is conducive to improving slaughter traits.
