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] Embodiment 1 (by weight percentage)

[0026]

[0027] The above raw materials are weighed according to the weight ratio, impurities are removed, crushed, and crushed until 95% of the mixed raw materials pass through a 60-mesh sieve, which can improve the digestion and absorption rate of the feed; then use a paddle mixer to mix the raw materials for 60 seconds, and pass in steam for conditioning Mature for 90s, tempering temperature is 80°C-85°C, the tempering temperature should not be too high, otherwise it will affect the retention rate of vitamins and other nutrients, 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 packaged, which is a health feed for preventing channel catfish from overwintering and dying.

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 channel catfish from overwintering and dying and a preparation method thereof. Background technique [0002] Channel catfish, also known as American catfish and channel catfish, belongs to Siluriformes and Catfish family, and is a freshwater warm-water fish. The fish has the characteristics of wide adaptability, miscellaneous feeding habits, wide temperature adaptability, fast growth, high yield, fresh and tender meat, high catch rate, and easy processing. It has now become the main species of freshwater aquaculture in my country. Since the large-scale breeding 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 of breeding density and the change of natural environment in recent years, channel catfish farming is facing the problem of ...
