Embodiment 1

[0042] manufacturing steps

[0043] 1. Fishmeal, soybean meal, brewer's yeast, squid viscera powder, glutinous rice powder, rice field eel mineral salt and other coarse raw materials that need to be finely pulverized are weighed according to the above formula ratio, cleaned through a coarse cleaning sieve, mixed with a mixer for the first time, and then superfine 98% crushed through 60 mesh.

[0044] 2. Weigh the high-gluten flour, rice field eel multidimensional, antifungal agent, and betaine according to the proportions of the above formula, and then clean and remove impurities.

[0045] 3. Put the raw materials of step 1 and 2 into the second blender and mix them evenly (CV≤5%), puff them through the extruder at low temperature (70-85°C), dry them in the dryer (65-80°C), and spray the oil outside the system Spray the fish oil in proportion, dry it in a cooler, sieve it with a grading sieve and pack it into bags.

Description

Technical field: [0001] The invention belongs to fish feed, in particular to a rice field eel feed, and also relates to a manufacturing method of the rice field eel feed. Background technique: [0002] Swamp eel is a carnivorous mainly partial omnivorous fish, and it is gluttonous in nature. At present, there are several kinds of rice field eel feed both at home and abroad: one is based on natural bait, according to "Field Field Eel Breeding Technology" (Jindun Press 1993, P22-23) and "Field Field Eel Loach Turtle Culture" (Agricultural Press 1992, P13 ) and other data, juvenile eels mainly feed on zooplankton such as rotifers, cladocerans, copepods and protozoa. Yellow eel juveniles and adults mainly feed on small fish and shrimps, aquatic insects, earthworms, snail clams, mussels, fly maggots, tadpoles, young frogs, fresh silkworm chrysalis, Tenebrio molitor, and animal waste. When food is scarce, some plant-based bait is also eaten. Affected by resources and seasons, th...
