Healthy and efficient special expanded compound feed for ietalurus punetaus and preparation process of healthy and efficient special expanded compound feed for ietalurus punetaus

Abstract

The invention relates to a healthy and efficient special expanded compound feed for ietalurus punetaus and a preparation process of the healthy and efficient special expanded compound feed for ietalurus punetaus. The expanded compound feed is prepared from, by mass, 1-2% of fish meal, 2-4% of chicken meal, 5-7% of lard residues, 5-8% of fermented soybean meal, 22-25% of soybean meal, 11-14% of rapeseed meal, 10-12% of cottonseed meal, 2-8% of rice bran meal, 5-10% of flour, 10-15% of barley, 1-2% of spray-dried animal blood cells, 3-6% of soybean oil, 1-2% of calcium dihydrogen phosphate, 1-2%of a compound premixed feed (multi-vitamin multi-mineral premix) and 1-3% of natural plant material powder. Since ietalurus punetaus is omnivorous and mostly carnivorous, fish meal is partially substituted by imported chicken meal and lard residues in the formula to save cost of the fish meal and increase animal protein source adding quantity; by adoption of the fermented soybean meal, anti-nutritional factors in the soybean meal are removed, macromolecular proteins are decomposed into easy-to-absorb micromolecular proteins and small peptides by microorganisms such as lactic acid bacteria, acidity of the feed is adjusted, feed intake of ietalurus punetaus is increased, multiplication of intestinal beneficial microbial flora is benefited, and the feed conversion rate is increased.

Description

technical field [0001] The invention relates to a channel catfish feed, in particular to a healthy and efficient channel catfish special puffed compound feed and a preparation process thereof. Background technique [0002] Channel catfish, also known as channel catfish, belongs to the family Siluriformes and is native to North America. It was introduced into China in 1984 to promote breeding. Because of its miscellaneous food habits, wide temperature adaptability, fast growth, delicious meat, and easy processing, it has become a An important freshwater aquaculture species in my country. At present, the annual output of catfish in the country has reached more than 220,000 tons, and there are large scales of breeding and consumption in Sichuan, Hunan, Hubei, Guangdong, Guangxi, Henan, Guizhou and other places. However, the channel catfish breeding materials in the market are relatively miscellaneous, and there are few special fork-tail feeds fed throughout the whole process, s...

AI Technical Summary

Problems solved by technology

However, the channel catfish breeding materials in the market are relatively miscellaneous, and there are few special fork-tail feeds fed throughout the whole process, such as tilapia feed, grass carp feed, pig feed, self-mixed ingredients, etc., which cannot well satisfy the nutrition of channel catfish Demand, risk of yellow meat (meat turns yellow, once the fish turns yellow, customers will reject it, therefore, the occurrence of this phenomenon will cause farmers to lose money), low breeding benefits; and more farmers want to save costs Directly feeding poultry and livestock offal such as chicken intestines and livers will cause serious pollution to water bodies, increase the risk of fish disease, and pose food safety hazards
