Problems solved by technology

However, in recent years, due to the influence of water quality and nutritional factors, the liver of tilapia generally turns yellow during the high temperature period from July to September every year, the feeding rate decreases, the growth rate slows down, and the fish body declines due to physical decline. The susceptibility to pathogens such as Streptococcus has increased, and once the disease occurs, it may cause serious economic losses in farming

Abstract

The invention provides an assorted feed for preventing the liver of a tilapia from becoming yellow. The assorted feed has balanced nutrition, and has good growth promotion effect to the tilapia on the basis of meeting normal growth nutrition demands of the tilapia, feed coefficient is reduced, and water deterioration or standard exceeding of water quality cannot be caused easily; meanwhile, serum bilirubin content of the tilapia in a high-temperature feeding period can be reduced effectively, and hepatoenteral circulation of bile is promoted; and activities of glutamic oxalacetic transaminase and glutamic-pyruvic transaminase of serum of the tilapia in the high-temperature feeding period are reduced, and activity of lysozyme of the serum is increased.

Description

【Technical field】 [0001] The invention relates to a tilapia feed, in particular to a compound feed for preventing tilapia liver from yellowing, and belongs to the field of aquaculture feed. 【Background technique】 [0002] Tilapia is a tropical fish belonging to the cichlid family. It has the characteristics of fast growth, white meat, and survival in poor water environments. It has a wide range of diets. Tilapia has strong disease resistance and can adapt to a wide range of environmental conditions. It is widely cultured in South China, with an annual production of nearly 1.5 million tons. With the development of artificial breeding technology and feed nutrition technology, the whole process of feeding commercial extruded feed can fully meet the normal growth needs of tilapia, and can obtain good breeding economic benefits. However, in recent years, due to the influence of water quality and nutritional factors, the liver of tilapia generally turns yellow during the high tem...
