Carp feed with antinutritional factor removed and preparation method of carp feed

Abstract

The invention belongs to the technical field of aquaculture and particularly relates to carp feed with antinutritional factor removed and a preparation method of the carp feed. The carp feed is prepared from the following raw materials: soybean meal, rapeseed meal, duck blood powder, wheat germ powder, bone meal, common sage herb powder, flaxseed protein, glucocerebroside, ferric citrate and microecologics. Compared with the prior art, the carp feed has the following advantages: the carp feed contains comprehensive nutrients, according to the ingestion characteristics of grass carp, the feed utilization rate is increased, the activities of transaminase and alkaline phosphatase in hepatopancreas and muscles of the grass carp are improved, use of antibiotics is reduced, the content of aspartic acid, glutamic acid and glycine in the muscles is increased, and the meat is more delicious, intake of antinutritional factors is reduced on the basis that the protein supplementation of the grass carp is guaranteed, so that the grass carp grows fast and has high disease resistance.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to carp feed for eliminating anti-nutritional factors and a preparation method thereof. Background technique [0002] Carp is one of the freshwater fishes with the most varieties, the widest distribution, the longest breeding history and the highest yield. It has strong adaptability, and its scales, brain, blood, eyes and skin all have certain medicinal effects, so it is becoming more and more popular. Most of them are farmed and eaten by humans. With the increase of demand, the scale of carp farming is also increasing. Carp has high protein content and is easy to digest. In the process of large-scale farming, due to the deterioration of the breeding environment and intensive The problem of chemical management often leads to the decline of carp protein content and protein quality. In order to ensure the protein content of carp, it is usually necessary to supplement r...

[0002] Carp is one of the freshwater fishes with the most varieties, the widest distribution, the longest breeding history and the highest yield. It has strong adaptability, and its scales, brain, blood, eyes and skin all have certain medicinal effects, so it is becoming more and more popular. Most of them are farmed and eaten by humans. With the increase of demand, the scale of carp farming is also increasing. Carp has high protein content and is easy to digest. In the process of large-scale farming, due to the deterioration of the breeding environment and intensive The problem of chemical management often leads to the decline of carp protein content and protein quality. In order to ensure the protein content of carp, it is usually necessary to supplement raw materials with high protein content such as rapeseed meal and soybean meal, but these raw materials contain a certain amount of anti-nutritional factors. Long-term feeding may affect the growth of carp and the meat quality of carp, so further research is needed on this issue
