Puffed floating formula feed special for rice field eels and preparation method thereof

Abstract

Belonging to the field of feed, the invention especially relates to a puffed floating formula feed special for rice field eels and a preparation method thereof. The formula feed is composed of, in terms of the mass of air dry matters: 30-40% of fish meal, 3-5% of squid paste, 5-10% of Antarctic krill powder, 10-20% of soybean meal, 10-20% of corn protein powder, 10-15% of high gluten flour, 3-5% of cassava modified starch, 3-5% of vital wheat gluten, 3-5% of kelp powder, 1-2% of calcium dihydrogen phosphate, 3-8% of fish oil, 0.1-0.3% of a multidimensional premix, 0.5-1% of a multimineral premix, 0.1-0.5% of choline chloride, 0.2-0.5% of salt, 0.01-0.05% of an antioxidant, and 0.05-0.2% of a mould inhibitor. Compared with ordinary feed, the formula feed provided in the invention has the advantages that: 1) it can better meet the nutritional needs of rice field eels, which can grow more rapidly; 2) the digestion utilization rate is enhanced, emission of nitrogen and phosphorus is lower, the feed has stronger stability in water and does not scatter when it is used for feeding together with minced fillet, the waste in water is less, the water pollution is small, and the meat quality of rice field eels is improved; and 3) the corn protein powder is added to the feed, and the natural yellow color of rice field eels can be maintained.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a special puffed floating water compound feed for eels and a preparation method thereof. Background technique [0002] Swamp eel belongs to the order of Synbratchidae, Syngillidae, and the genus Swamp Eel, also known as squid, squid, squid, snake fish, long fish, is a rare freshwater fish. Swamp eel is a tropical and warm-temperate fish that lives at the bottom of the sea and has strong adaptability. It can survive in rivers, lakes, ditches and rice fields. During the day, it likes to drill holes in humus mud or rock crevices with water on the embankment. Medium-sized cave dwellers, omnivorous and gluttonous, with a variety of small animals as the mainstay, and the most vigorous food intake in summer. In cold seasons, they can not eat for a long time without dying. Because of their advantages such as fast growth, good meat quality, delicious taste, and high economic value, Favore...

Problems solved by technology

In the process of breeding eels, the farmers use artificial compound feeds in a small proportion. Because of their low food attractant, they need to feed a large amount of natural animal baits such as water worms, earthworms, and silver carp that are smashed, resulting in the compound feed collapsing quickly. , The waste is very large. In this mode, the eels grow slowly and seriously pollute the water quality. In addition, the eels raised in this environment lack the umami taste of the wild eels, and the meat quality is poor and the body color is dark.
