Food-calling digestion-promoting expanded feed for largemouth basses in high-temperature period and preparation method thereof

Abstract

The invention provides a food-calling digestion-promoting expanded feed for largemouth basses in a high-temperature period and a preparation method thereof. The feed comprises 20-30% of Peruvian superfish meal, 18-32% of tilapia powder, 10-15% of spray-dried porcine animal blood cells, 2-7% of fermented soybean meal, 2-7% of 46% decorticated soy bean meal, 7-10% of high-gluten flour, 1-3% of calcium dihydrogen phosphate, 0.3-1% of refined fish oil, 0.3-1% of soybean phospholipid oil, 0.3-1% of soybean oil, 1-4% of a squid extracting liquid, 1-3% of fish dissolved pulp, 2-5% of a special premix for largemouth basses, 1-3% of a Chinese herbal medicine food-calling anti-heat stress preparation mixture and 1-3% of a fresh fermented lactic acid bacteria preparation mixture. The feed disclosedby the invention has anti-heat stress, food-calling and digestion-promoting effects, completely replaces the use of frozen fresh trash fish in a high-temperature period, reduces the risk of food safety of largemouth basses to a certain extent, also can reduce the breeding of pathogenic bacteria, and can effectively improve the survival rate of largemouth basses in a high-temperature period.

Description

technical field [0001] The invention relates to the field of fish feed, in particular to a California perch puffed feed that attracts food and promotes digestion in a high temperature period and a preparation method thereof. Background technique [0002] California perch is a rare carnivorous fish, scientifically known as largemouth bass, which originates in California, USA. It is welcomed by the market because of its delicious meat, strong disease resistance, rapid growth and easy catch. The domestic market demand for California sea bass is huge. It is understood that Guangdong, Zhejiang, Sichuan, and Guizhou in China have aquaculture, and the annual market demand remains above 350,000 tons. [0003] The Pearl River Delta region of Guangdong Province is the region with the highest amount of California perch farming. Since 2017, the annual output can reach more than 200,000 tons. At present, the proportion of California perch farming in the Pearl River Delta region is about...

AI Technical Summary

Problems solved by technology

However, California perch is not resistant to high temperature and has a great impact on heat stress. Conventional compound feeds are faced with the problems of low feeding rate of artificial compound feed and difficult digestion when the water temperature is above 30°C during the high temperature period (July-September).
