Application of rubber seedcake in megalobrama amblycephala formula feed and formula of megalobrama amblycephala formula feed

Abstract

The invention relates to an application of rubber seedcake in a megalobrama amblycephala formula feed and a formula of the megalobrama amblycephala formula feed, belonging to the technical field of aquaculture. Rubber seedcake partially takes the place of a composite plant protein source formed by bean pulp, cottonseed meal and rapeseed meal and is added into the megalobrama amblycephala formula feed, The formula feed comprises the following raw materials by weight percent: 3-6% of fish meal, 7-12% of bean pulp, 12-22% of cottonseed meal, 12-22% of rapeseed dregs, 13.5-40.5% of rubber seedcake, 8-12% of wheat middling, 5-17% of wheat bran, 1-4% of soybean oil, 0.3-0.5% of soybean lecithin, 1.0-1.8% of monocalcium phosphate, 0.05-0.1% of vitamin C phosphate, 0.1-0.2% of choline chloride, 0.01-0.03% of ethyoxyl quinoline, 2-3% of zeolite powder, 0.2-0.4% of salt, 1-3% of bentonite, 0.5-1.0% of mineral substance gunk and 0.5-1.0% of vitamin premix, and the sum of the weight percentages of all raw materials is 100%. As the rubber seedcake is fully employed to be the protein raw material of the megalobrama amblycephala formula feed, the protein sources in shortage such as the bean pulp, the cottonseed meal and the rapeseed meal are saved, and the feed is free of harmful effect on megalobrama amblycephala; meanwhile the formula cost is lowered, the feed coefficients are reduced, high cost performance is achieved, and the culture benefits of megalobrama amblycephala are increased.

Description

technical field [0001] The invention relates to a compound feed for bream, in particular to the application and formula of a rubber seed cake in the compound feed for bream, 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 my country's aquatic products mainly comes from the aquaculture industry. At present, my country's aquatic product aquaculture production 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 and soybea...

Problems solved by technology

[0004] In the prior art, patent CN101194669A relates to the process of using rubber seed cake (meal) to produce protein feed, but does not involve the ratio and efficacy of rubber seed cake (meal) replacing other protein raw materials; patent CN101473889A involves the use of rubber seed kernels to prepare protein feed The formula and method of raw materials, but it mainly uses rubber seeds to prepare protein feed raw materials, rather than directly using rubber seeds as protein feed

In view of the obvious differences in the tolerance and utilization efficiency of anti-nutritional factors contained in rubber seed cakes of different species of animals, the dosage given in the existing formula as a protein feed raw material to prepare aquatic feed is extremely unreasonable and cannot meet the needs of aquaculture
