Problems solved by technology

However, judging from the actual breeding application effect, drug treatment such as antibiotics has not curbed the large-scale occurrence of the disease, and has led to the existence of a large number of drug residues

Embodiment 1

[0025] Example 1 (by weight percent)

[0026]

[0027] The above-mentioned raw materials are weighed according to the weight ratio, impurity-removed, pulverized, and pulverized until 95% of the mixed raw materials pass through a 60-mesh sieve, so that the digestion and absorption rate of the feed can be improved; then the raw materials are mixed with a paddle mixer for 60 s, and the steam is conditioned and tempered. After curing for 90s, the tempering temperature is 80℃-85℃. The tempering temperature should not be too high, otherwise it will affect the retention rate of nutrients such as vitamins, and it should not be too low, otherwise it will affect the starch gelatinization degree and sterilization; finally, the logistics After being dried and cooled to room temperature, it is a health-care feed for preventing channel catfish from dying over winter. Example 2 (by weight percentage)

Embodiment 3

[0031] Example 1 (by weight percent)

[0032]

[0033] The above-mentioned raw materials are weighed according to the weight ratio, impurity removal, pulverization, and pulverized until 95% of the mixed raw materials pass through a 60-mesh sieve; then the raw materials are mixed with a paddle mixer for 60 s, and the steam is quenched and tempered for 90 s, and the tempering temperature is 80 ℃. -85℃; finally, the material is dried, cooled to room temperature and then packaged, which is a health-care feed for preventing the death of channel catfish overwintering.

Abstract

The invention relates to a fodder for channel catfish, and particularly relates to a health care fodder capable of preventing channel catfish from dying during overwintering and a preparation method thereof. The health care fodder comprises the following raw materials by percentage by weight: 15%-40% of concentrated feed, 1%-8% of fish meal, 5%-20% of dephenolized cottonseed protein, 5%-20% of wheat, 5%-25% of wheat middling, 2%-10% of meat and bone meal, 1%-3% of zeolite powder, 1%-3% of fish oil, 0.4%-2.5% of nutrition additive, 0.05%-0.1% of toxin adsorbent, and 0.02%-0.03% of antioxidant. The health care fodder can improve the appetite of the channel catfish, allows the channel catfish to grow rapidly, enhances the immunity of the channel catfish, effectively improves the fatness and weight of the channel catfish, and improves the intestinal health of the channel catfish; and after overwintering, the survival rate of the channel catfish reaches over 80%, which is improved by more than 55% compared with that of the channel catfish fed with common fodder.

Description

technical field [0001] The invention relates to a channel catfish feed, in particular to a health-care feed for preventing the death of channel catfish overwintering and a preparation method thereof. Background technique [0002] Channel catfish, also known as American catfish and channel catfish, belong to the order Catfish and the family Channel catfish, and are freshwater warm water fish. The fish has the characteristics of wide range of adaptation, miscellaneous diet, wide suitable temperature, fast growth, high yield, fresh and tender meat, high catch rate and easy processing. It has become the main species of freshwater aquaculture in my country. Since the large-scale cultivation of channel catfish in 2000, my country's aquaculture production reached 220,000 tons at its peak, and more than 40,000 tons were used for export. However, with the increase in breeding density and changes in the natural environment in recent years, channel catfish farming has faced the proble...
