Stress-resistant antibiotic-free compound feed for grass carps

Abstract

The invention belongs to the technical field of feeds, and particularly relates to a stress-resistant antibiotic-free compound feed for grass carps. The stress-resistant antibiotic-free compound feedconsists of the following raw materials in parts by weight of 46% of soybean meal, 46% of cottonseed meal, 200 type rapeseed meal, imported DDGS, fish meal, corn protein powder, washed rice bran, soybean oil, phosphatide powder, calcium dihydrogen phosphate, bentonite, flour, 98.5% lysine, choline chloride, VC phosphate ester, VE acetate, myo-inositol, ethoxyquin, sodium chloride, garlicin, livernourishing and gallbladder function promoting elements, vitamins for grass carps, and trace elements for grass carps. According to the stress-resistant antibiotic-free compound feed for grass carps, stress resistance substances of the VC phosphate ester, the VE acetate, the myo-inositol, the liver nourishing and gallbladder function promoting elements, the fish meal and the like and nutrient substances easy to absorb are added in cooperation of the grass carps, the self constitutions and the stress resistance of the grass carps can be improved, the stress reaction in the grass carp selling process can be reduced, and economic losses caused by debonding, scaling, death and the like can be reduced.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to an anti-stress and non-antibiotic compound feed for grass carp. Background technique [0002] Feed is the main substance that provides the main energy and basic nutrients for animals. According to different purposes and different raw materials, some different formulas are designed accordingly. Aiming at the phenomenon of grass carp selling fish in high temperature season, the process of dragging and transporting fish may easily cause stress reactions such as scale loss, debonding, and death of the fish body, resulting in large economic losses. A special feed is designed and produced to strengthen the fish body. The purpose of anti-stress ability is to reduce the economic loss caused by stress in pulling nets, catching fish, and transporting. [0003] The patent "CN201310450679.X" discloses a compound feed for improving the anti-stress ability of grass carp. However, the...

Aiming at the phenomenon of grass carp selling fish in high temperature season, the process of dragging and transporting fish may easily cause stress reactions such as scale loss, debonding, and death of the fish body, resulting in large economic losses. A special feed is designed and produced to strengthen the fish body. The purpose of anti-stress ability is to reduce the economic loss caused by stress in pulling nets, catching fish, and transporting

[0003] The patent "CN201310450679.X" discloses a compound feed for improving the anti-stress ability of grass carp. However, the anti-stress feed mainly adopts three enzyme preparations of high-temperature resistant phytase, dextranase and protease in the feed. To improve the anti-stress ability of grass carp, due to the poor high-temperature resistance of enzyme preparations, the feed needs to be adjusted at a high temperature of above 90°C for more than 70 seconds before pelleting, resulting in a large loss of enzyme preparations and poor production control. Finally, it is difficult to guarantee the anti-stress ability

Secondly, this feed needs to be used throughout the whole process, which greatly increases the cost of feed for farming, thereby reducing the income of farming.

[0004] The grass carp anti-stress extruded compound feed and its production method described in the patent "CN201410076643.4" adopts an extruding process, the process is complicated, the operation is difficult, and the equipment price is high, which leads to an increase in the processing cost of the feed; the temperature of the feed during the extruding process When it reaches 120°C, nutrients such as multivitamins are destroyed by high-temperature processing; this feed must be used throughout the process, which greatly increases the cost of breeding feed, thereby reducing the breeding income

[0005] The grass carp anti-stress extruded compound feed and its production method described in the patent "CN201410813104.4" adopts an extruding process, which is complicated in process, difficult in operation, and expensive in equipment. The processing cost of the feed is greatly increased; secondly, the feed must be used throughout the whole process, which greatly increases the feed cost of breeding, thereby reducing the breeding income
