Feed for breeding river crabs and preparation method thereof

Abstract

The invention discloses feed for breeding river crabs and a preparation method thereof. The invention aims at providing the feed for breeding river crabs, the river crabs have obvious growth effects after eating the feed, and the feed is free of any side effects. An additive formula mainly provides the river crabs with vitamins, mineral ion elements, various enzymes and other components required by growth of the river crabs for accelerating the growth of the river crabs, and the components are nuisance-free for the growth of the river crabs. The additive formula also contains antibiotics and various bacteria for inhibiting growth of harmful bacteria in the internal and external environments of the river crabs, so the river crabs have obvious growth effects and low mortality after eating the feed containing a basic formula and the additive formula, and the feed is free of any side effects.

Description

technical field [0001] The invention relates to a feed formula, in particular to a feed and a preparation method for cultivating river crabs. Background technique [0002] River crabs are favored by people because of their delicious meat. The traditional breeding feed is a mixture of basic formula and growth promoter. The basic formula includes imported fish meal, soybean meal, peanut meal, cotton meal, rapeseed meal, aquatic yeast, citric acid residue, flour , soybean lecithin, squid paste, bentonite, calcium dihydrogen phosphate, the basic formula mainly provides the basic nutrients needed for survival of river crabs, among which imported fish meal, soybean meal, peanut meal, cotton meal and rapeseed meal mainly provide amino acid nutrition, and citric acid residue Acidify the feed to enhance the palatability of the feed. Soybean lecithin can promote the shelling of crabs and improve the survival rate of crabs. Calcium dihydrogen phosphate provides calcium ions and phospho...

[0002] River crabs are favored by people because of their delicious meat. The traditional breeding feed is a mixture of basic formula and growth promoter. The basic formula includes imported fish meal, soybean meal, peanut meal, cotton meal, rapeseed meal, aquatic yeast, citric acid residue, flour , soybean lecithin, squid paste, bentonite, calcium dihydrogen phosphate, the basic formula mainly provides the basic nutrients needed for survival of river crabs, among which imported fish meal, soybean meal, peanut meal, cotton meal and rapeseed meal mainly provide amino acid nutrition, and citric acid residue Acidify the feed to enhance the palatability of the feed. Soybean lecithin can promote the shelling of crabs and improve the survival rate of crabs. Calcium dihydrogen phosphate provides calcium ions and phosphorus elements to promote the shelling of crabs and then grow shells. Squid paste It is a food attractant. Adding aquatic yeast to the feed can promote the digestion and absorption of river crabs. On the one hand, bentonite can bind the components in the feed of river crabs, and on the other hand, it can clean the intestines of river crabs and provide a source of nutrients for the growth of river crabs. Rare trace elements, the traditional growth promoter uses olaquindox, which can promote the assimilation of protein and accelerate the weight gain of river crabs, and olaquindox has antibacterial ability, but olaquindox is easy to remain in the body of river crabs after eating olaquindox. When the amount of olaquindox accumulates to a certain level, it will easily cause the death of river crabs, and after people eat river crabs, olaquindox will remain in the human body, causing harm to the human body
