Artificial initial feed for preventing enteritis of live fry and preparation method and feeding method thereof

Abstract

The invention relates to an artificial initial feed for preventing enteritis of live fry. The feed consists of white fish meal, Antarctic krill meal, squid viscera meal, a yeast extract, refined fishoil, lecithin, fermented soybean meal, wheat gluten, high-gluten flour, choline chloride, a composite premix, calcium dihydrogen phosphate and an antioxidant, wherein the composite premix contains enzymatic and bacterial preparations; the composite premix is added after other components are mixed, expanded and formed. On the one hand, the artificial initial feed needs to meet the nutrient demandsof the fry; on the other hand, raw materials easy to digest and high in absorption conversion rate are screened; according to the characteristics of the imperfect digestive system development and fragile intestinal tract of the fry, in cooperation with the exogenous enzymatic and bacterial preparations, the fry are assisted in digestion.

Description

technical field [0001] The invention relates to a bait for raw fish fry, in particular to an artificial opening bait for preventing enteritis of raw fish fry, a preparation method and a feeding method thereof. Background technique [0002] At present, the aquaculture output of Chinese snakehead (commonly known as raw fish in Guangdong) has reached 518,000 tons (2017 Fishery Yearbook), most of which are hybrid snakeheads (Channa maculate ♀X C. argus ♂), which have good hybrid advantages, not only It has the characteristics of delicate meat, delicious taste, less thorns and more meat, and also has medicinal functions such as nourishing the spleen and promoting water, removing blood stasis and promoting new life, nourishing and recuperating, etc. It is deeply loved by consumers and is the most important aquaculture species in the Pearl River Delta special aquaculture one. The hybrid snakehead is a cross between the snakehead (Channa argus) and the spotted snakehead (Channa mac...

Problems solved by technology

Enzyme preparations are currently recognized as probiotic components in livestock and poultry feeds that can assist animals in digestion and improve intestinal health. However, aquatic feeds are easily inactivated after high-temperature expansion, which leads to the fact that enzyme preparations are rarely added to aquatic feeds. The main reason, and because of this, there is currently no bait to prevent intestinal diseases of raw fish larvae
