Problems solved by technology

This is due to the fact that when the animals are exposed to heat stress, the sympathetic nerves of the animals are excited, the gastrointestinal motility is weakened, the secretion of digestive juice is reduced, the enzyme activity is reduced, and indigestion causes the stagnation time of chyme in the gastrointestinal tract to be prolonged. On the one hand, the chyme fills the gastrointestinal tract. The feeding center is inhibited, leading to a decrease in animal feed intake. On the other hand, chyme is fermented in the gastrointestinal tract to produce gas, which leads to regurgitation in animals.
From June to September, common puffed feed floats on the surface of the pond, raw fish refuse to eat, and even regurgitation occurs. For a long time, raw fish have slow growth, thin body, decreased immunity, and increased mortality, which has brought huge losses to farmers. economic loss
Most of the current anti-heat stress agents are aimed at livestock and poultry, and anti-heat stress agents for aquatic animals, especially raw fish, have not been reported

Abstract

The invention provides a feed additive capable of preventing spitting and relieving heat stress for snakehead. The feed additive is prepared from the following raw materials: radix scutellariae, bamboo shavings, reed rhizome, radix aucklandiae, oligosaccharides, dimethyl-beta-dimethylpropiothetin, nucleotide, vitamin C, and middling powder. The feed additive disclosed by the invention can be added to the snakehead basal fed to quicken emptying of chyme in the gastrointestinal tract, prevent spitting for snakehead, promote ingestion of snakehead, meanwhile strengthen intestinal health, improve digestive enzyme activity, and increase the feed efficiency and the production effectiveness.

Description

[0001] 【Technical field】 [0002] The invention relates to an aquatic feed additive, in particular to a feed additive for preventing raw fish from spitting and alleviating heat stress. [0003] 【Background technique】 [0004] Raw fish, scientific name hybrid snakehead, belongs to the distant hybrid offspring of black snakehead and spotted snakehead. It is one of the important economic fish breeding species in my country. It is widely loved by people because of its delicious meat and rich nutrition. At present, it only has the breeding area of ​​Guangdong Province. It has exceeded 5000hm 2 . The suitable growth temperature for raw fish is 25-28°C, and the period from June to September is the rapid growth period of raw fish. However, it is summer from June to September, especially in Guangdong, where the high temperature lasts for a long time, and the water temperature often exceeds 30°C, which is easy to cause raw fish heat stress response. The most obvious feature when animal...
