酿酒酵母培养物“乐华康肽”对樱桃谷肉鸭生长性能的影响

The Effects of Yeast Culture＂ Novaculture＂ on Growth Performance of Cherry Valley Ducks

为研究酿酒酵母培养物乐华康肽对樱桃谷肉鸭生产性能的影响，试验选择1日龄樱桃谷肉鸭雏320只，公母各半，按公母比例，随机分为2组，每组4个重复，每个重复40只鸭。试验组饲喂基础日粮，对照组在基础日粮基础上添加5％乐华康肽，并调整营养水平使营养水平与对照组接近。结果表明：试验组肉鸭与对照组肉鸭采食量差异不显著（P〉0．05），试验组肉鸭体增重显著高于对照组（P〈0．05），试验组料肉比显著低于对照组（P〈0．05）。表明酿酒酵母培养物乐华康肽能促进樱桃谷肉鸭的生长，提高樱桃谷肉鸭饲料利用率，降低料肉比。

A total of 320 1 - day - old cherry valley ducks were randomly divided into 2 treatments with 4 replicates of 40 each. Male and female in half, according to the proportion of male and female. The control group was fed with basic diet, the experimental group was fed with basic diet supplemented with 5% novaculture. The results showed that：The average feed intake of experimental group was not significantly higher gain of the treatment group was significantly than control group （ P 〉 0. 05 ）. The average weight higher than control group （P 〈 0. 05 ）. The feed con- version rates of 5 % novaculture group were significantly lower than control group （ P 〈 0. 05 ）. It was eoncluded that 5% novaeulture with basic diet could significantly promote growth, improve feed utilization and reduce feed conversion.
