Application of rubber seedcake to oncorhynchus mykiss mixed feed and formula of feed

Abstract

The invention relates to an application of a rubber seedcake to an oncorhynchus mykiss mixed feed and a formula of the feed, and belongs to the field of aquaculture techniques. The fixed feed comprises the following components by weight percentage: 15-20% of fish meal, 6-10% of corn protein powder, 7-10% of soybean protein concentrate, 13-18% of bean dregs, 9-12% of rapeseed dregs, 7-10% of cottonseed dregs, 5-15% of the rubber seedcake, 1-7% of wheat middling, 10-12% of bean oil, 0.3-0.5% of soybean lecithin, 0.7-1.5% of monocalcium phosphate, 0.05-0.1% of vitamin C phosphate, 0.1-0.2% of choline chloride, 0.01-0.03% of ethoxy quinoline, 0.5-1.0% of a mineral premix compound, and 0.5-1.0% of a vitamin premix compound. According to the application and the formula, short protein sources such as the bean dregs, the cottonseed dregs and the rapeseed dregs are saved; the cost of the formula and the coefficient of the feed are lowered and reduced; the feed has a high cost performance; the aquiculture benefit of oncorhynchus mykiss is improved.

Description

technical field [0001] The invention relates to a compound feed for rainbow trout, in particular to the application and formula of a rubber seed cake in compound feed for rainbow trout, and belongs to the technical field of aquaculture. Background technique [0002] With the improvement of people's living standards, people's demand for aquatic products is increasing. In recent years, the increase of aquatic products in my country mainly comes from the aquaculture industry. At present, the production of aquatic products in my country has accounted for 72% of the total output. With the development of aquaculture industry, the demand for compound feed raw materials is increasing. my country is a country with a shortage of protein resources, and the shortage of feed protein sources is particularly prominent. There is a gap of more than 25 million tons of protein raw materials every year. In recent years, the market prices of conventional protein raw materials such as fishmeal a...

AI Technical Summary

Problems solved by technology

Rainbow trout is a carnivorous fish. Its feed generally uses conventional protein raw materials such as fish meal, soybean meal, cottonseed meal, and rapeseed meal as the main protein source. The protein content in the feed is required to be more than 40%, which reduces the breeding benefits of rainbow trout.
