蝇蛆粉对肉鸡生长性能和死亡率的影响

Effect of house fly larvae meal on growth performance and mortality of mountain chickens

本试验选择了270只健康1日龄二郎山山地鸡,按初始体重无差异原则随机分为3组,即对照组、4%鱼粉组、4.5%蝇蛆粉组,分小鸡(1～21日龄)和中鸡(22～42日龄)年龄段测定各组鸡的生长性能指标及死淘率。结果表明:添加4.5%蝇蛆粉组相对于添加4%鱼粉组而言,在小鸡和中鸡阶段更能显著提高肉鸡的生产性能,同时降低其死淘率。可见,蝇蛆粉除了能够满足雏鸡的营养需要外,还具有鱼粉不具备的优势。

In order to determine the growth perfmTnance, mortality rate about＇ the stage of small chickens （l-21-days-old） and the stage of middle chickens （22-42-days-old）, 270 male mountain chickens of one-day-old were randomly divided into three groups, the basal diet supplemented with 4% fish meal and with 4.5% house fly larvae meal. The content of ration was same in each group. The results showed that 4.5% house fly substituting protein feed were significantly higher than those of fish meal to improve the growth performance and reduce the mortality at the stage of small chickens and middle chickens. So, in addition to meeting chickens nutritional needs, the house fly larvae meal had the advantages that fish meal without.
