Embodiment 1

[0016] A compound feed for juvenile yellow catfish, comprising the following components and their parts by weight: 30 parts of fermented soybean meal, 15 parts of fish meal, 5 parts of flour, 7 parts of vegetable oil, 0.2 part of citric acid, 0.3 part of phytase, 0.2 part of immune enhancer share. The ratio of raw materials of the above-mentioned compound feed is reasonable, which can improve the immune function of juvenile catfish, has anti-stress effect, and can improve the growth performance, apparent digestibility of nutrients, deposition of mineral elements and anti-oxidation of juvenile catfish. performance, effectively preventing lipid peroxidation, and inhibiting lipid oxidation in the tissue microsomal of yellow catfish muscle; the high level of active phosphorus in the feed makes the nutrients release into a form that can be absorbed by the fish, reducing the bait coefficient, Increase the utilization rate of the fish body to the nutrients such as phosphorus, protein...

Embodiment 2

[0024] A compound feed for juvenile yellow catfish, comprising the following components and their parts by weight: 40 parts of fermented soybean meal, 10 parts of fish meal, 10 parts of flour, 5 parts of vegetable oil, 0.3 part of citric acid, 0.2 part of phytase, and 0.25 parts of immune enhancer share.

[0025] The preparation method of the fermented soybean meal is as follows: add water to the soybean meal until the water content is 50%, then add methionine, stir evenly, then autoclave for 25 minutes, cool the room temperature, inoculate the compound strain according to the inoculation amount of 10%, and ferment at 30°C for 4 days , freeze-dried, crushed and passed through a 250-mesh sieve to obtain fermented soybean meal. The weight ratio of above-mentioned methionine and compound strain is 1:400, and the ratio of L-methionine and D-methionine in methionine is 60:1; Lactobacillus casei in compound strain: Bacillus subtilis: the weight ratio of saccharomycete is 1: 1.3:0.4...

Embodiment 3

[0028] A compound feed for juvenile yellow catfish, comprising the following components and their parts by weight: 40 parts of fermented soybean meal, 10 parts of fish meal, 10 parts of flour, 5 parts of vegetable oil, 0.3 part of citric acid, 0.2 part of phytase, and 0.25 parts of immune enhancer share.

[0029] The preparation method of the fermented soybean meal is as follows: add water to the soybean meal until the water content is 50%, stir it evenly, sterilize it under high pressure for 25 minutes, inoculate the compound strain according to the inoculation amount of 10% after cooling the room temperature, ferment at 30°C for 4 days, freeze-dry, Crush and pass through a 250-mesh sieve to obtain fermented soybean meal. The weight ratio of Lactobacillus casei:Bacillus subtilis:saccharomyces in the above-mentioned composite strains is 1:1.3:0.4.

[0030] The composition and parts by weight of the immune enhancer are: 13 parts of β-glucan, 5 parts of fructooligosaccharide, v...

Abstract

The present invention discloses a compound feed of young yellow catfish. The compound feed comprises the following ingredients in parts by weight: 30-50 parts of fermented soybean meal, 5-15 parts offish meal, 5-15 parts of flour, 3-7 parts of vegetable oil, 0.2-0.4 part of citric acid, 0.1-0.3 part of phytase and 0.2-0.3 part of an immunopotentiator. Beneficial effects are as follows: the feed is reasonable in raw material ratios, can improve the immune function of the young yellow catfish, has an anti-stress effect, can promote the growth of the young yellow catfish, improves meat quality,and is long in shelf life and high in utilization rate and safety.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a compound feed for juvenile yellow catfish. Background technique [0002] The yellow catfish belongs to the Siluriformes ( Siluriformes ), Cylindae ( Bagridae ), Peltezha ( Pelteobagrus ). It is a kind of economic freshwater fish endemic to the Asia-Pacific region. Yellow catfish has a high economic value. In recent years, the sustained and high price has made the yellow catfish aquaculture market in China more and more extensive. And along with the increase of market demand, natural resources gradually decrease, impel the scale of artificial culture of yellow catfish to become larger and larger. However, there are still some technical problems in the artificial cultivation of yellow catfish, and the cultivation technology is not yet mature. At present, with the popularization of artificial feeding, compound feed is the main feeding method, but the nutritional ingredients i...
