Low-phospholipid medium-growing freshwater shrimp feed

Abstract

The invention discloses a low-phospholipid medium-growing freshwater shrimp feed. The feed consists of the following components in percentage by mass: 15 to 16 percent of fish meal, 12 to 13 percent of fermented bean pulp, 15 to 16 percent of bean pulp, 13.95 to 25 percent of wheat flour, 10 to 11 percent of rapeseed meal, 10 to 12 percent of cottonseed meal, 3 to 4 percent of rice bran, 3 to 4 percent of squid meal, 2 to 3 percent of shrimp shell meal, 2 to 3 percent of zeolite powder, 1.4 to 2 percent of calcium dihydrogen phosphate, 0.5 to 1.0 percent of soybean phospholipid oil, 0.05 to 0.1 percent of lysolecithin and 1.0 percent of premix. The feed is used for medium-growing freshwater shrimps with body lengths of over 2.0 centimeters; and the consumption of phospholipid is reduced in the feed, and the consumption of cheap raw materials such as the rapeseed meal, the cottonseed meal, the wheat flour and the like is increased, so the cost of the feed is reduced and the benefits ofan enterprise are increased under the condition that survival and growth are not affected.

Description

technical field [0001] The invention relates to a feed for freshwater shrimp cultivation, in particular to a low-phospholipid low-phospholipid feed for middle-aged freshwater shrimp, which belongs to the technical field of feed production. Background technique [0002] Phospholipids play a very important role in the nutritional metabolism of shrimp. They can emulsify and promote the digestion and absorption of fatty acid bile salts and fat-soluble substances, effectively promote the absorption and transportation of cholesterol in feed by shrimp, and improve the growth and survival rate of shrimp. However, the ability of shrimp to synthesize phospholipids is very limited and cannot meet the needs of metabolism. It must be added in an appropriate amount in the feed, generally 2% to 3%. However, the price of phospholipids is too high at present, and the price of phospholipid oil for feed has reached 6500. Yuan / ton, which has brought great cost pressure to feed enterprises. Co...
