Embodiment 1

[0037] An environment-friendly river crab feed is made from the following raw materials by weight: 15% of high-quality fish meal, 3% of blood meal (AP301), 5% of squid paste, 17% of soybean meal, 3.64% of peanut cake, 6% of rapeseed meal, and 20% of cotton meal %, wheat 10%, sorghum flour 15%, soybean lecithin 2%, fish oil 1%, soybean oil 1%, phytase 500U / Kg (adding carrier to account for 1% by weight), calcium dihydrogen phosphate 1%, arginine Acid 0.1%.

[0038] The productive test found that after adopting the feed of the present invention to raise for 3 months, the average weight of river crabs was 146g / only, the feed factor was 1.3, the deposition rates of N and P were respectively 29% and 28%, and the river crabs fed faster. Its cost is 3541 yuan / ton.

Abstract

The invention discloses an environment friendly river crab feed, which consists of fish meal, blood meal (AP301), cuttlefish cream, soybean meal, peanut cake, rapeseed meal, cottonseed meal, wheat, strong flour, granulesten, defatted rice bran, corn gluten feed (DDGS), malt root, fish oil, vegetable oil, phytase, calcium biphosphate and special phagostimulant for the river crab. The utilization rate of the feed for the river crab can be improved by adopting the environment friendly river crab feed of the invention, thereby promoting the benefit of breeding, reducing the loss of nitrogen and phosphorus in the feed and improving the water quality of the breeding.

Description

technical field [0001] The invention relates to a feed specially used for river crabs, in particular to an environment-friendly feed for river crabs, which is especially suitable for improving the water quality of river crab culture and discharging tail water up to the standard. Background technique [0002] River crab is the freshwater crab with the largest output in my country. Its edible part has a protein content of 14%, a fat content of 5.9%, and a carbohydrate content of 7%. It contains a variety of amino acids and vitamins, and is the crown of conventional aquatic products. important aquaculture species in the basin. With the progress of society and the needs of the vegetable basket project, its production significance and economic benefits have been fully affirmed. In 2005, the output of river crab in my country reached about 450,000 tons, and the breeding area has a tendency to further expand. [0003] Because river crabs are active at night, are timid, eat slowly,...
