Feed capable of promoting feed intake for micropterus salmoides

Abstract

The invention relates to a feed capable of promoting the feed intake for micropterus salmoides. The feed comprises alpha-starch, bean pulp, a yeast hydrolysate, fish meal, white fish meal, fish oil, phospholipid oil, monocalcium phosphate, a premixture of vitamins for fish, a premixture of minerals for fish, choline chloride, vitamin C, vitamin E, a functional additive containing a folium cortex eucommiae extract, fish and shrimp gourmet powder, sodium humate and an additive containing tributyrin. According to the feed, by adding the vitamin C, the vitamin E, the folium cortex eucommiae extract, the fish and shrimp gourmet powder, the sodium humate and the additive containing tributyrin into the feed for the micropterus salmoides, the palatability of the feed for the micropterus salmoides is improved, the feed intake (the feed intake is increased by 5% or above) of the micropterus salmoides in a high temperature period is increased, and the feed with the higher cost-performance ratio for the micropterus salmoides is provided for customers and is superior to other products in market competition.

Description

technical field [0001] The invention relates to a California perch feed, in particular to a California perch feed that promotes feed intake. Background technique [0002] With the improvement of people's living standards, the demand for fresh aquatic products is increasing. California sea bass has delicious meat, no intermuscular thorns, and affordable prices. It is favored by consumers and has a huge consumer market. Breeding California perch in the Pearl River Delta region has unique geographical and climate advantages, and it also has obvious advantages in the industrial chain of seedlings, feed, and distribution. In recent years, with the maturity of the whole recipe and process of California perch, there has been an upsurge of California perch farming across the country. Since 2015, the total amount of California sea bass farming in the country has increased from the initial 300,000 tons to 500,000 tons in 2018, and it is expected that the total output will reach 1 mi...

AI Technical Summary

Problems solved by technology

[0003] California perch is native to North America and is a temperate fish. It is very unsuitable for high temperature weather in summer. The food intake during high temperature periods drops significantly, which affects its production time.

Since the breeding of California perch is mainly concentrated in the Pearl River Delta area, the temperature difference in summer in different regions is not large, so the output (fish production) time of each farmer is roughly the same, which has a great impact on the market, and the supply exceeds demand, resulting in a drop in price. Breeding time waits for the fish to come out when the market demand is strong, which greatly increases the risk of farming
