Feed improving digestion and absorption capabilities of silver carps

Abstract

Feed improving digestion and absorption capabilities of silver carps is disclosed. The feed includes, by weight, 40-45 parts of soybean protein, 15-25 parts of soybean phosphatide, 3-7 parts of table salt, 3-7 parts of a vitamin supplement, and 1-3 parts of L-alanyl-L-glutamine. Beneficial effects of the feed are that materials are easily available, the feed is safe and nontoxic and the feed conversion ratio of the silver carps can be significantly increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture feed, in particular to a feed for improving the digestion and absorption capacity of silver carp. Background technique [0002] Silver carp, also known as silver carp, water carp, jumping carp and silver carp, belongs to Cyprinidae, Cyprinidae, and is one of the four famous big fishes. Silver carp is a typical filter-feeding fish. It mainly eats zooplankton in the fry stage, and gradually turns to eat phytoplankton when it is more than 1.5 cm long. It also eats soy milk, bean dregs powder, bran and rice bran, etc., and prefers to eat artificial microparticles. Compound feed. [0003] The body is flat on the sides, slightly taller, fusiform, blue-gray on the back, white on both sides and abdomen. The head is large. The eyes are set low. The scales are tiny. The horny ridge in the middle of the abdomen extends from the bottom of the pectoral fins to the anus. Pectoral fins do not extend be...
