Embodiment 1
[0014] 1. Accurately weigh 38kg of soybean meal, 18kg of corn gluten meal, 15kg of rapeseed meal, 23.35kg of secondary powder, 2.27kg of cellulose, 0.2kg of compound amino acid, 0.1kg of immune enhancer, 0.4kg of betaine, 2kg of fish oil, and choline chloride 0.3kg, vitamin C 0.1kg, multi-dimensional premix 0.15kg, multi-mineral premix 0.1kg, phytase 0.03kg.
[0015] 2. Grind the solid feed raw materials through a pulverizer so that all of them can pass through a 60-mesh sieve, then mix them evenly according to the proportion, then fully mix them with the liquid feed raw materials fish oil and water, extrude and granulate, and bake at 60°C Dry.
[0016] 3. Spray the phytase buffer solution evenly on the surface of the feed, wrap it with fish oil, and then dry it at 37°C.
[0017] 4. Cool the dried pellet feed at room temperature, seal and pack it and store it for later use.
Embodiment 2

Abstract
The invention relates to environment protection fish-meal-free spot ietalurus punetaus compound feed, which belongs to the field of compound feed and processing thereof. The compound feed of the invention comprises the following ingredients in mass percent: 38 to 53 percent of bean dregs, 5 to 20 percent of corn protein powder, 0 to 15 percent of cotton dregs, 0 to 15 percent of vegetable dregs, 15 to 24 percent of wheat shorts, 1 to 2.5 percent of cellulose, 0.1 to 0.3 percent of compound amino acid, 0.05 to 0.1 percent of immunity enhancing agents, 0.3 to 0.5 percent of lycine, 2 percent of fish oil, 0.3 percent of choline chloride, 0.1 percent of vitamin C, 0.15 percent of multidimensional premix compounds, 0.1 percent of polymineral premix compounds and 0.03 percent of phytase (5000 u/g). The preparation method comprises the preparation processes of raw material crushing, mixing, extruding pelletization, vacuum spray coating and baking. The invention has the advantages of simple preparation, low price and balanced nutrition, can meet the growth requirement of the ietalurus punetaus, can reduce the production cost, can improve the assimilation and the utilization of nutrient substances, and can reduce the water body pollution caused by nitrogen and phosphor discharge in the culture process.
Description
(1) Technical field [0001] The invention relates to a green and environment-friendly channel catfish compound feed and a preparation method thereof, in particular to a fishmeal-free compound feed suitable for channel catfish breeding, and belongs to the field of compound feed and its processing. (2) Background technology [0002] The channel catfish (lctalurus punctatus) belongs to Siluriformes, Cateridae, and is native to the Americas. It was introduced into my country by the Hubei Provincial Institute of Fishery Sciences in 1984. After several years of research and promotion, it has become a widely cultivated species in my country. It has wide appetite, fast growth, strong adaptability and disease resistance, good quality, and great market potential. It is a nutritious high-end banquet food and has always been loved by domestic and foreign farmers and consumers. The quality of feed for channel catfish is one of the key technologies for the healthy development of its breedi...
