Special environment-friendly high-yield feed for gold Ctenopharyngodon idellus

Abstract

The invention discloses special environment-friendly high-yield feed for gold Ctenopharyngodon idellus. The feed is prepared from the following raw materials in parts by weight: 20-40 parts of corn flour, 10-20 parts of purple sweet potato flour, 10-15 parts of soybean protein powder, 8-15 parts of rapeseed cake, 2-5 parts of spirulina powder, 1-4 parts of vivipara pulp, 2-9 parts of marine red yeast powder, 1-8 parts of beer yeast powder, 2-8 parts of peanut oil, 0.1-0.8 part of choline chloride, 0.05-0.2 part of astaxanthin, 0.1-0.5 part of anti-mildew agent, 0.05-0.1 part of multivitamin and 0.03-0.15 part of composite mineral. According to the special environment-friendly high-yield feed for gold Ctenopharyngodon idellus, the nutrient ingredients are scientifically matched according to the living habits of gold Ctenopharyngodon idellus, and the growing speed of gold Ctenopharyngodon idellus can be accelerated. Meanwhile, the utilization rate of gold Ctenopharyngodon idellus in feed protein and energy is improved, the discharge of N in metabolic waste of gold Ctenopharyngodon idellus is reduced, the pollution to the culture water environment is reduced, and the harm of ammonia and nitrite nitrogen in aquatic water to gold Ctenopharyngodon idellus is reduced. The feed is also capable of improving the utilization of phosphorus in plant raw material, reducing entry of phosphorus into culture water environment, improving the culture environment and preventing eutrophication of the water body caused by unbalanced N and P proportions.

Description

technical field [0001] The invention relates to a kind of fish feed, more precisely, it is a special environment-friendly high-yield feed for golden grass carp. Background technique [0002] Golden grass carp belongs to Cypriniformes, Cyprinidae, Cyprinidae, and subfamily, Grass carp. In 1996, my country's Shunde District Agricultural and Fishery Station transferred from Japan to Russia and introduced the best new species of fish that began to be reproduced on a large scale in 2001. Because its body color resembles the skin color of a Russian beauty, it is also known as the Russian golden grass carp. Golden grass carp is transplanted to various parts of the world as pioneers because of its unique feeding and foraging methods. [0003] At present, there is large-scale farming of golden grass carp in many places in my country, and the feed used is mostly goldfish feed or general pellet feed, and some farmers also feed with shrimp feed for shrimp. These feeds are not the most...

Problems solved by technology

These feeds are not the most suitable feed for golden grass carp, which limits the growth rate of golden grass carp. At the same time, residual bait and metabolites of aquatic animals in the aquaculture process are the main sources of N and P in the water body, while N in the water body , P imbalance will not only cause water eutrophication, but also one of the main factors that induce aquatic animal diseases
