随着我国畜禽水产养殖业的进一步发展,优质动物蛋白的短缺日趋严重,进口鱼粉的价格不断上涨,进而使养殖业成本增加,效益下降。一些不法商贩对进口鱼粉掺杂、使假,对养殖业的损害更大。为了寻求进口鱼粉的理想替代产品,中国农科院北京海淀国际农业开发中心与黑龙江省临江高蛋白饲料厂联合研制生产了《雅迪喜》(原爱迪喜)PY生物活性蛋白粉。该产品菌体蛋白含量高,可消化率高,氨基酸比例适当,富含多种维生素,有促进生长,免疫功能强的功效。我们进行了用进口鱼粉和《雅迪喜》PY生物活性蛋白粉养鱼的对比试验,现将结果报告如下。1 材料与方法1.1 试验地点及鱼种
With the further development of livestock and poultry aquaculture in our country, the shortage of high-quality animal protein has become increasingly serious. The price of imported fishmeal has been on the rise, further raising the cost of aquaculture and reducing the efficiency. Some unscrupulous traders doping imported fish meal, so that the fake, greater damage to the aquaculture industry. In order to seek the ideal substitute for imported fishmeal, the Chinese Academy of Agricultural Sciences Beijing Haidian International Agricultural Development Center and the Heilongjiang Province Linjiang high protein feed plant jointly developed and produced “Yadi” (formerly IDI) PY bioactive protein powder. The bacterial protein content of the product, digestible high, the proportion of amino acids appropriate, rich in vitamins, to promote growth, strong immune function. We conducted a comparative test of fishmeal with imported fishmeal and “Yadixi” PY bioactive protein powder, and the results are reported below. 1 Materials and methods 1.1 test sites and species
