一种环保型泥鳅饲料养殖效果初探

Study on the Culture Effect of An Environmental Friendly Loach Feed

随着社会公众对水质保护的日益重视,环保型饲料的研究逐渐成为热点;通过对环保型泥鳅饲料、旧配方工艺泥鳅饲料、品牌饲料A、品牌饲料B、品牌饲料C 5种饲料进行养殖对比试验,比较了环保型饲料的养殖效果。结果表明,环保型饲料在饲料利用率、回捕率、饵料系数、饲料出鱼重、平均增重方面优于其他4种饲料,并与旧配方工艺饲料、饲料B、饲料C差异显著,但与饲料A差异不显著。环保型饲料比旧配方工艺饲料在平均增重方面提高了18.12%、饲料利用率提高了21.69%、饵料系数降低了17.46%、饲料出鱼重提高了21.39%、回捕率提高了20.79%。

With more and more attention to the protection of water quality from the public, environmental friendly feed has become a hot research topic. The breeding experiments of five feed groups fed with environmental friendly loach feed, old formula loach feed, branded feed A, branded feed B and branded feed C were conducted to test the effect of environmental friendly loach feed. The results showed that the feed utilization rate, recapture rate, feed coefficient, fish/feed weight and weight gain of environmental friendly feed was better than the other four kinds of feed, which was significantly different to old formula loach feed, branded feed A and branded feed B compared; while not significantly different to branded feed C.Compared to the old formula feed group, the weight gain of environmental protection feed group has increased by 18.12%;feed utilization rate has increased by 21.69%; feed coefficient has decreased by 17.46%; fish/feed weight has increased by21.39%; while recapture rate has increased by 20.79%.
