Compound feed of grass carp in fingerling period and preparation method thereof

Abstract

The invention provides a compound feed of a grass carp in a fingerling period and a preparation method thereof and the compound feed can be used for solving the problems of prevalent diseases and high mortality of the grass carp under the condition of high density cultivation. The compound feed is prepared from the following raw materials in percentage by weight: 2.5-3.5% of Peruvian fishmeal, 12-15% of soybean meal, 27-31% of rapeseed meal, 12-15% of cottonseed meal, 7-8.5% of vinasse, 9-11% of corn germ meal, 4.8-6% of wheat, 12-15% of wheat bran, 0.15-0.3% of table salt, 1.8-2.2% of soybean oil, 1.4-1.6% of monocalcium phosphate, 0.18-0.22% of choline chloride, 0.02-0.05% of microecology, 0.02-0.04% of bile acid, and 0.9-1.1% of premix. The compound feed provided by the invention is scientific in proportion and simple in preparation, and can be used for reducing the use of antibiotics and positively affecting the growth performance of the grass carp as well as improving the economic performance.

Description

technical field [0001] The invention relates to a grass carp feed, in particular to a grass carp species compound feed and a preparation method thereof. Background technique [0002] In recent years, the aquaculture industry has developed rapidly. In order to pursue high profits, farmers have continuously increased the nutritional level and stocking density of feed to pursue higher growth rates and economic benefits, resulting in frequent fish diseases and high mortality during the breeding period. , especially grass carp. [0003] Traditional grass carp feed cannot meet the growth needs of grass carp under high-density and high-nutrient farming conditions. In order to pursue a fast growth rate and improve the nutritional level of grass carp feed, especially the level of crude fat, the excessive accumulation of nutrients in the abdominal cavity of grass carp, fatty liver and other nutritional diseases often occur, resulting in a decline in the body condition of the cultured...
