Abstract

The invention discloses a compound feed for grass carps and a preparation method thereof. The compound feed is prepared from the following raw materials by weight percent: 16% of wheat, 17% of 46% of soybean meal, 5% of full fat soybean, 13% of 40% of cottonseed meal, 10% of common rapeseed meal, 8% of Indian rapeseed meal, 9% of full fat rice bran, 2% of soybean oil, 0.3% of plant extract, 2% of monocalcium phosphate, 0.1% of 60% of choline chloride, 12% of distillers dried grains and soluble (DDGS), 5% of Chinese fish meal, 0.2% of salt, 0.2% of complex vitamin premix and 0.2% of complex mineral premix. The preparation method comprises the following steps: weighing the raw materials by weight percent and throwing the raw materials into a grinder to be ground; and throwing the mixture into a granulator to be granulated after mixing. The compound feed and the preparation method have the following beneficial effects that the nutritional requirements of the grass carps are met on the basis of lowering the feed cost, the normal feed intake of the grass carps is ensured, development of intestinal tracts of the grass carps is promoted and the utilization rate of the feed is increased.

Description

technical field [0001] The invention relates to a fish culture feed, in particular to a grass carp compound feed and a preparation method thereof. Background technique [0002] The nutritional value of Indian rapeseed meal is very high, the crude protein content is about 35.0% to 45.0%, the amino acid is relatively complete, and there are almost no limiting amino acids. Compared with other oilseed meal protein, the content of methionine and cystine in rapeseed meal protein The lysine is slightly lower than that of soybean, and the biological value of its protein is 3 to 5, which is higher than that of soybean protein. In addition, the calcium, phosphorus, and magnesium in rapeseed meal are three times that of soybean meal, and the selenium is eight times that of bean cake. It is also rich in iron, manganese, copper, zinc and other elements. Rapeseed meal is also rich in vitamins and minerals, making it an inexpensive and readily available source of high-quality feed protein...
