Abstract

The invention discloses an extruded biological feed with a function of improving immunity of river crabs. The extruded biological feed comprises the following components in parts by weight: 5-20 parts of fish soluble, 1-10 parts of earthworm pulp, 5-20 parts of 43 bean pulp, 0-40 parts of rapeseed meal, 0-30 parts of cottonseed meal, 8-20 parts of flour, 10-30 parts of rice bran, 0-3 parts of fish oil, 0-2 parts of soybean oil, 1 part of river crab gunk, 0-0.2 part of kosteletzkya virginica tuberous root powder. According to the extruded biological feed with the function of improving immunity of river crabs, disclosed by the invention, specific raw materials and ratios are selected according to bio-utilization efficiencies of the river crabs to different protein sources and amino acids, so that the equilibrium of the amino acids is realized; the immunity of the river crabs is greatly improved, the organism disease-resisting capability is enhanced, and the morbidity of the river crabs is reduced, so that the rate of survival is increased; the mean weight, the food coefficient and the rate of survival of the river crabs are remarkably increased, and the cost is remarkably lowered, so that the extruded biological feed has a very wide market prospect.

Description

technical field [0001] The invention belongs to the field of breeding, and in particular relates to an extruded biological feed for improving the immunity of river crabs. Background technique [0002] River crabs are also called "crabs" or "hair crabs", and belong to the crustaceans of the phylum Arthropoda. The carapace formed by the combination of the head and the chest is square and hard. There is a pair of eyes on the front of the body, and two pairs of very sharp crab teeth on the side. The first pair of appendages of the crab are called chelicerae, and the surface is covered with fluff; behind the chelicerae, there are 4 pairs of walking legs, with flat sides and longer; the abdominal limbs have degenerated. The male and female of the river crab can be distinguished from its abdomen: the abdomen of the female is round, and the abdomen of the male is triangular. [0003] River crab is the freshwater crab with the largest output in my country. It is deeply loved by co...
