利用畜禽粪肥养鱼,是我国池塘养鱼的一大特点,它具有化害为利,变废为宝,以肥代饵,净化环境等优点。我们在1983—1984年,进行了用鲜鸡粪养鱼,再拿部分小鱼喂鸡,循环利用饵料的试验。结果如下:1、鸡粪中含有较好的营养成分试验用配合饲料的营养成分经过测定后,采取单个笼养,然后收集排出的鸡粪,进行分析。产蛋鸡吃进配合料与排出鲜鸡粪的比例为1:1.2～1.3。由于鲜鸡粪含水分80%,吃进干粉料与排出的干鸡粪比例为1:0.28,两者的营养成分如表1、2:
The use of livestock manure fish, pond fish is a major feature of our country, which has the harm for the benefit, turning waste into treasure, to feed on behalf of the bait, environmental purification and so on. In 1983-1984, we conducted experiments that used fresh chicken manure to fish, and then part of the fish fed chickens to recycle the bait. The results are as follows: 1, chicken manure contains better nutrients Nutritional components of the test compound after testing, take a single cage, and then collect the discharged chicken manure for analysis. The proportion of laying hens fed with ingredients and discharged fresh chicken manure is 1: 1.2 ~ 1.3. As the fresh chicken manure contains 80% water, the ratio of dry chicken manure to dry powder discharged is 1: 0.28, the nutritional contents of both are shown in Tables 1 and 2:
