Specific large-scale grass carp puffed compound feed and preparation method thereof

Abstract

The present invention relates to a specific large-scale grass carp puffed compound feed and a preparation method thereof, and belongs to the technical field of aquatic product puffed feed production. The feed comprises 10-35 parts of soybean meal, 10-35 parts of rapeseed meal, 5-15 parts of cottonseed meal, 8-15 parts of DDGS, 5-15 parts of rice bran, 8-20 parts of flour, 3-8 parts of cassavas, 3-8 parts of sorghum, 2-4 parts of soybean oil, 1-3 parts of calcium dihydrogen phosphate, 1-2.5 parts of bentonite, 0.05-0.2 part of 98.5% lysine hydrochloride, 0.01-0.05 part of Kelikang (a feed additive), 0.05-0.1 part of choline chloride, 0.3-0.5 part of multivitamin premix, 1.0-3.0 parts of compound mineral premix, 0.01-0.05 part of antioxidant and 0.1-0.15 part of mildew preventive. The provided large-scale grass carp specific floated and puffed compound feed aims at the situation that no specific feed is provided in the breeding process of the large-scale grass carps currently. By combining the nutrient demand and digestive physiology demand characteristics, the puffed compound feed can greatly improve the breeding efficiency under the premise of not affecting the production performances.

Description

technical field [0001] The invention relates to a grass carp feed and a preparation method thereof. More specifically, the invention relates to a special buoyant puffed compound feed for large-scale grass carp and a preparation method thereof, belonging to the technical field of production of puffed feed for aquatic products. Background technique [0002] grass carp( Ctenopharyngodonidella ) is a typical herbivorous fish, belonging to Cyprinidae, Cyprinidae, Yaluo subfamily, and Grass carp. Grass carp has always been the freshwater fish with the largest production and consumption in my country. In 2014, the national grass carp aquaculture output was 5.37 million tons, accounting for 18.3% of the total freshwater aquaculture production in the country (China Fishery Yearbook, 2015), and occupies an important position in my country's agricultural economy. . Grass carp is cultivated in all regions of the country, with the two lakes and Guangdong and Guangxi as the main breeding...

Problems solved by technology

[0007] The present invention aims to solve the problems of increasing liver and gallbladder load during the growth process of large-scale grass carp and low economic benefits of breeding due to the common use of grass carp breeding feed in the prior art, and the unreasonable and unscientific formula of the existing large-scale grass carp feed In order to solve the problem, a special buoyant extruded compound feed for large-scale grass carp is provided. This invention is based on the characteristics of large-scale grass carp’s utilization of protein and carbohydrates, especially the characteristics of strong utilization of carbohydrates. Based on the existing research In terms of scientific selection of protein and starch raw materials and their proportions, while reducing the formulation cost, the nutritional and physiological characteristics of large-scale grass carp are maximized, which not only ensures the healthy growth of large-scale grass carp, but more importantly, can greatly improve the economic benefits of farming
