两种育雏方式对半番鸭生长性能的影响研究

Study on the Effects of Two Kinds of Brooding Way on the Growth Performance of Mule Ducks

为了研究不同育雏方式对半番鸭生长性能的影响,选择1日龄半番鸭雏鸭,采用地面平养和网上平养两种育雏方式,饲养管理条件相同,计算各处理组的日增重、料肉比、生长均匀度及疾病发生率等指标。试验结果表明,与半番鸭地面平养育雏相比,6周龄时网上平养育雏鸭平均体重提高246g(P<0.05);料肉比降低0.25(P<0.05);6周龄雏鸭均匀度提高了6.21%(P<0.05);网上平养育雏组球虫病及呼吸道疾病发生率显著低于地面平养育雏(P<0.05)。

In order to research the effects of different brooding ways on the growth performance of mule ducks, chose 1 day old mule ducks, used two brooding ways of floor-rearing and net-rearing, in the same feeding and management conditions, calculated the daily gain, the feed gain ratio, the growth uniformity, the incidence of disease, and so on indexs in each treatment group. The test results showed that, compared with floor-rearin, the average weight of mule ducks by net-rearing at 6 week old increased 246 g （P〈0.05）, the feed gain ratio reduced 0.25 （P〈0.05）, the growth uniformity of 6 week old increased 6.21%（P〈0.05）, the incidence rate of coccidiosis in chicken and respiratory diseases by net-rearing were significantly lower than by floor-rearing（P〈0.05 ）.
