Fry feed for improving survival rate of snakeheads

Abstract

The invention mainly relates to the technical field of feed processing, and discloses a fry feed for improving the survival rate of snakeheads. The feed is prepared from the following raw materials: corn flour, wheat middling, black bean meal, blood powder, fish meal, shrimp meal, chicken powder, beef powder, fruit-vegetable powder, an additive, bacillus natto and lactobacillus. The raw materialsare rich and balanced in nutrients, so that the digestive absorption of snakehead fry is promoted, and the survival rate of the fry reaches 91.6%, and a feed conversion ratio is 1.21, and the breedingefficiency of snakeheads is obviously improved. The feed is inoculated with the bacillus natto, and a wet feed is subjected to natto fermentation so as to generate rich enzyme substances, promote thedigestive absorption of the fry, improve the metabolism of the fry, and accelerate growth and development. After the natto fermentation, the blood powder, the fish meal, the shrimp powder, the chicken powder, the beef powder and the fruit-vegetable powder are added to the feed, and the obtained feed is inoculated with the lactobacillus and subjected to low-temperature fermentation so as to reducethe pH value of the raw materials, facilitate the gastrointestinal functions of the fry, generate a large amount of micromolecular nutrients and fragrance components, promote digestive absorption, enhance the organ functions of the fry, and improve the survival rate of the fry.

Description

technical field [0001] The invention mainly relates to the technical field of feed processing, in particular to a feed for larvae that improves the survival rate of black carp. Background technique [0002] Black fish, also known as snake head fish, black fish, mullet, black stick, snake head, has tender meat, delicious taste, high protein, low fat, and has the health care functions of removing blood stasis, nourishing and recuperating, invigorating spleen and diuresis, promoting muscle and blood, and accelerating wound healing , can also treat edema, arthralgia due to dampness, beriberi, hemorrhoids, scabies and other diseases. Black fish has a high meat content and no intermuscular spines. "; In the traditional breeding process of snakeheaded fish, the survival rate of newly hatched snakeheaded larvae is the highest, but 50-60%, generally 20-30%, or even lower, which obviously increases the breeding cost of snakeheaded fish; the existing patent document CN 105394445 A is p...

"; In the traditional breeding process of snakeheaded fish, the survival rate of newly hatched snakeheaded larvae is the highest, but 50-60%, generally 20-30%, or even lower, which obviously increases the breeding cost of snakeheaded fish; the existing patent document CN 105394445 A is public Adding a large amount of traditional Chinese medicine ingredients will reduce the palatability of the feed and affect the consumption of snakehead fish. At the same time, the protein content of snakehead fish obtained is low, which will affect the meat quality and taste of snakehead fish
