Formula of grass carp feed

Abstract

The invention relates to the technical field of feed processing, and particularly relates to a formula of grass carp feed. The grass carp feed is prepared from the following raw materials in parts byweight: 20-30 parts of soybean meal, 30-35 parts of rice sprout meal, 12-15 parts of meat and bone meal, 4-5 parts of rape-seed cake meal, 8-10 parts of silkworm chrysalis meal, 4-5 parts of fish meal, 3-4 parts of barley flour, 2-3 parts of fiveleaf gynostemma herbs, 1-2 parts of amino acid, 2-3 parts of sophora flavescens, 2-3 parts of borreria stricta, 2-4 parts of hawthorn roots, 5-7 parts ofkelp base, 2-4 parts of sunflower leaves, 1-2 parts of phlegmariurus petiolatus and 1-3 parts of phagostimulant. The feed has a reasonable formula, can meet the requirement for grass carp growth at different stages, and can be used for effectively improving the meat quality and nutritional value of grass carp, promoting growth of grass carp, enhancing the skin anti-bacterial performance of grass carp and reducing the incidence rate of grass carp.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a grass carp feed formula. Background technique [0002] Animal husbandry is an important part of modern agriculture. In the process of agricultural modernization, the proportion of the output value of animal husbandry to the gross national output value will gradually increase. At the same time, with the development of the national economy and the improvement of people's living standards, the social demand for livestock and poultry products also shows a gradually increasing trend. The feed industry is an important part of the animal husbandry industry. It is not only an important bridge connecting the planting industry, livestock and poultry breeding industry and animal product processing industry, but also ensures the supply of livestock and poultry products, maintains the safety of livestock and poultry products, and builds a healthy and orderly modern animal husbandry ...

Problems solved by technology

In recent years, with the development of the aquaculture industry, grass carp farming has become a traditional grass feed feeding method, which has been transformed into a feeding method based on concentrate and supplemented by green feed. The growth period of grass carp has also been shortened from two years to one year. The economic benefits have been significantly improved, but due to the high-density breeding conditions, the physique of grass carp fed with concentrated feed has decreased significantly, and the excessive breeding density will cause stress, reduce the resistance of fish to diseases, and lead to low survival rates. During the process, it is vulnerable to red skin disease, gill rot disease, enteritis disease and hemorrhagic disease. These four diseases are called "four diseases of grass carp". The outbreak of these diseases will bring a devastating blow to the grass carp breeding industry. Therefore, the large-scale and high-density farming of grass carp is greatly restricted.

Long-term practice has shown that injecting antibiotics into grass carp can prevent the "four diseases of grass carp"; however, these antibiotics will enter the human body along with people eating various fish products, which indirectly leads to the abuse of antibiotics and may cause a variety of drug-induced diseases. There may even be multidrug-resistant "superbugs"
