不同阶段饲养法对肉鸡生产性能的影响

摘要

This experiment was conducted to investigate the effect of different segments feeding method on growth performance in broilers.150 1-day-old Rose broilers were randomly divided into 3 treatments with 3 replications,of 15 each. Two phase,three phase,six phase feeding method were adoped.The experiment period was 42 days.The results showed that:compared with groupⅠ,the average daily gain (ADG)of treatment Ⅱ siginificantly increased and feed to gain ratio (F/G) significantly decreased in the whole experiment period (P < 0.05).The results indicated that treatment Ⅱ was proved to be the best.%为研究阶段饲养法对肉鸡生产性能的影响，试验选择1日龄罗斯308肉鸡135只，随机分为3组，每组3个重复，每个重复15只。Ⅰ～Ⅲ组分别采用两阶段、三阶段、六阶段饲养法。饲养42 d，测定各生产性能指标。结果表明：试验全期，Ⅱ组日增重较Ⅰ组显著提高（P＜0.05），料重比显著降低（P＜0.05）。由此可见，三阶段饲养法效果最好。
