Feed as well as preparation method and application thereof

Abstract

The invention belongs to the technical field of aquaculture, and discloses a feed as well as a preparation method and application thereof. The feed comprises the following components: a camellia plant extract and additives, wherein the additives are composed of at least two selected from monocalcium phosphate, choline chloride, ethoxyquin, glutamine and N-carbamylglutamic acid. The feed also comprises an euphausia superba extract. The camellia plant extract and the additives are matched for use, so the prepared feed can remarkably improve the disease resistance and the survival rate of snakeheaded fish. The feed further contains the euphausia superba extract; the euphausia superba extract is rich in nutrient substances and further contains various active substances such as protein digestive enzymes, analogous mycotoxin amino acids and the like and has rich nutritional value; and as the euphausia superba extract is added into the prepared feed, the nutritional value of the feed can be effectively improved, the digestion function of the snakehead fish can be effectively promoted, and the rapid growth of the snakehead fish is thus facilitated.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a feed and its preparation method and application. Background technique [0002] Fish is a common aquatic animal. There are many types of fish. Different fish have different shapes and different growth characteristics, which will further lead to different breeding feeds used. Snakeheads belong to the family Channaidae and the genus Channa. The overall shape of the snakehead is that the front part of the body is cylindrical and the rear part is flattened. The body color is gray-black, the back and top of the head are darker, the abdomen is pale white, there are irregular black spots on each side of the body, and black stripes on the side of the head; the odd fins have black and white spots, and the even fins are grayish yellow with different With regular spots, snakeheads are bottom-dwelling carnivorous and ferocious fish. They usually like to live in shallow wat...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the feed for cultivating snakeheads generally overcomes the problem of amino acid imbalance of a single protein source by adding multiple protein sources, which is beneficial to improve feed utilization, reduce ammonia nitrogen emissions, and reduce environmental pollution. However, in order to improve the Disease resistance and survival rate, usually need to add some antibiotic ingredients

The addition of antibiotics will easily lead to the emergence of drug-resistant bacteria, which is not conducive to the sustainable and healthy development of the aquaculture industry, and is also not conducive to human health

Simultaneously, in the prior art, the nutritional ingredients of the feed used for cultivating snakeheads are not comprehensive enough, resulting in slow growth of snakeheads
