Feed capable of enhancing immunity of overwinter carp

Abstract

The invention discloses a feed capable of enhancing immunity of overwinter carp. The feed is prepared from the following components in parts by weight: 40 to 50 parts of corn protein flour, 20 to 30 parts of wheat bran, 25 to 32 parts of buckwheat powder, 10 to 15 parts of earthworm meal, 6 to 10 parts of meat powder, 12 to 16 parts of crab shell powder, 10 to 14 parts of egg white, 10 to 15 parts of black bean, 5 to 10 parts of fructus clausenae lanii, 5 to 10 parts of dried tangerine peel, 3 to 7 parts of liquorice root, 7 to 12 parts of seaweed meal, 2 to 10 parts of yeast powder, 5 to 9 parts of rhizoma dioscoreae, 1 to 5 parts of stevia rebaudiana, 1 to 5 parts of anti-disease agent, and 2 to 5 parts of phagostimulant. The feed capable of enhancing immunity of the overwinter carp has the characteristics that the green and environment-friendly effects are realized; the growth function of the overwinter carp is well improved; the diseases of the overwinter carp are effectively prevented and controlled; the immunity is enhanced, and the economic benefit is further improved; the feed contains various nutrients, the nutrients are balanced and reasonable, and the growth speed of the carp fries is accelerated.

Description

technical field [0001] The invention relates to an aquatic feed, in particular to a feed for improving the immunity of overwintering carp. Background technique [0002] Carp is a benthic omnivorous fish that eats both meat and vegetables. At the same time, carp, like most freshwater fish, is a stomachless fish species with a thin and short intestinal tract and a fast metabolism, so the eating habit is to eat less and frequently. The traditional carp feed has simple nutrients, contains less protein and other nutritional elements, and can only meet the general needs of carp during the growth process. Under some special climate or seasonal conditions, it cannot meet the growth needs of carp. [0003] When carp is planted in winter, there are many problems. For example, during the wintering period, the fish body is easy to grow parasites, causing the carp to itch and climb the edge in winter, and then forming frostbite; the immunity of overwintering carp is very low, which will...

Problems solved by technology

The traditional carp feed has simple nutrients, contains less protein and other nutrients, and can only meet the general needs of carp during the growth process. Under some special climate or seasonal conditions, it cannot meet the growth needs of carp.

[0003] When carp is planted in winter, there are many problems. For example, during the wintering period, the fish body is easy to grow parasites, causing the carp to itch and climb the edge in winter, and then forming frostbite; the immunity of overwintering carp is very low, which will cause the infection of mold and fungus to flood; In addition, during wintering, carp will suffer from air bubble disease due to water quality that is too green and fat, weather and other reasons. Therefore, it is necessary to make great progress in preventing infection and improving carp immunity in terms of feeding and feed.
