不同饲养方式对江南白鹅生产性能和屠宰性能的影响

Effects of Different Feeding Modes on the Productive Performance and Slaughter Performance of Jiangnan Goose

[目的]比较不同饲养模式下肉鹅的生产性能。[方法]选用3 600只江南白鹅,随机分为4组,分别采用舍内地面+舍外运动场+河流(Ⅰ组)、舍内地面+舍外运动场+小水池(Ⅱ组)、舍内网架+舍外运动场+河流(Ⅲ组)、舍内网架+舍外运动场+小水池(Ⅳ组)4种方式进行饲养,研究不同饲养方式对江南白鹅生产性能和屠宰性能的影响。[结果]采用舍内网架+舍外运动场+河流饲养方式的Ⅲ组江南白鹅的体重显著高于其他组(P<0.05),Ⅲ组江南白鹅的上市体重高于其他组,但差异不显著(P>0.05);各组江南白鹅的死淘率差异不显著(P>0.05),Ⅲ、Ⅳ组江南白鹅的死淘率略低于Ⅰ、Ⅱ组,Ⅲ组江南白鹅的死淘率低于Ⅳ组;各组屠宰性能无显著差异(P>0.05)。[结论]舍内网架+舍外运动场+小水池的饲养模式是较理想的饲养方式,可进行推广应用。

[Objective] The aim was to compare goose production performance under different feeding modes.[Method] 3 600 geese were randomly divided into 4 groups, adopting four treatments including the inner ground ＋outside the stadium ＋river（Ⅰgroup）, inner ground＋outside the stadium ＋small pools（Ⅱgroup） , inner network frame ＋outside the stadium＋river（Ⅲ group） , inner network frame ＋outside the stadium＋small pools（Ⅳ group） , effects of different feeding modes on the productive performance and slaughter performance of Jiangnan goose were studied.[ Result] The weight of Jiangnan goose in inner network frame ＋outside the stadium＋river（Ⅲ group） was significantly higher than that in other groups（P〈0.05）, while there was no significant difference（P〉0.05） when they were on the market;the dead rate of Jiangnan goose in each group was no significant difference（P〉0.05）, the dead rate of goose in Ⅲ and Ⅳ group was slightly lower thanⅠ, Ⅱ group, the dead rate of goose in Ⅲ groups was lower than Ⅳ group; there was no significant difference of slaughter performance in each group（P〉0.05）.[Conclusion] The inner network frame ＋outside the stadium, small pools of feed pattern is a more ideal way of breeding, which can be applied to the actual feed.
