Composite Chinese herbal feed additive premix for preventing and treating discoloration of Pelteobagrus fulvidraco

Abstract

The invention discloses a composite Chinese herbal feed additive premix for preventing and treating discoloration of Pelteobagrus fulvidraco, comprising following materials by weight: based on per ton of feed, 1200-2500g of rheum officinale, 300-1600g of root of red-rooted salvia, 500-350g of marigold, 1000-3000g of silybum marianum, 300-1800g of pseudo-ginseng, 600-2200g of radix scutellariae, 800-1200g of golden cypress, 1000-1500g of astragalus mongholicus, 1000-3000g of motherwort, 800-4000g of garlic and 1000-3000g of hawthorn, wherein the adding weight of the composite Chinese herbal feed additive premix in per ton of Pelteobagrus fulvidraco compound feed is 10-20kg. The premix is optimized after large-scale productive experiments in several years so as to be safe and effective in long-term use and has no toxic side effects; and the immune function and anti-stress capability of the Pelteobagrus fulvidraco cultivated on a high-density intensive condition can be notably improved. Many experiments show that the serum lysozyme activity, macrophage phagocytic ability and serum complement energy of the Pelteobagrus fulvidraco are improved after the Pelteobagrus fulvidraco eats feed with the additive premix. The bred Pelteobagrus fulvidraco has high survival rate, bright and natural body color, strong anti-stress capability and low feed coefficient.

Description

technical field [0001] The invention relates to a feed additive premix, in particular to a compound Chinese herbal medicine feed additive premix for preventing discoloration of yellow catfish. Background technique [0002] Yellow catfish belongs to the order Siluriformes, Siluridae, and the genus Yellow catfish, commonly known as yellow-bone fish, yellow curtin or thorny fish, and is a small bottom-dwelling omnivorous freshwater fish. Its meat is tender, delicious, nutritious and of high economic value. Yellow catfish is farmed all over the country. It has wide temperature adaptability, strong adaptability, and fast growth rate. The fry that breed in the current year can reach commercial specifications within one year, and the group yield is high. It is a cultured species with great market potential. And because it is a benthic fish, it is suitable for polyculture with various fish, so the scale of artificial breeding is expanding year by year. Now Guangdong, Guangxi, Huna...

AI Technical Summary

Problems solved by technology

However, artificial compound feed is still immature in terms of formula technology, selection of raw material varieties and quality control of raw materials, and at the same time due to the interaction of breeding environment, breeding density, water quality conditions and diseases, etc., it often leads to discoloration of the cultivated yellow catfish. , the main performance is that the body color of yellow catfish will turn black, white, mottled or transparent after a period of time. The selling price of commercial fish of this color will be greatly reduced, which will affect the profits of farmers and seriously hinder Further development of the farming industry
