Fry nutrition powder and preparation method thereof

Abstract

The invention discloses fry nutrition powder and a preparation method thereof. The fry nutrition powder solves the problem that the existing fry feeding technology using soya-bean milk as feed has the defects of single nutrient and large labor intensity. The fry nutrition powder comprises, by mass, 3-5% of homemade fish meal, 14-16.5% of soybean meal, 18-22% of Canada rapeseed meal, 12-16% of homemade rapeseed meal, 5-7% of rapeseed cake, 5-7% of cottonseed meal, 7-9% of common flour, 11-13% of wheat middling, 7-9% of rice bran, 0.8-1.5% of soya-bean oil, 1.5-2.5% of zeolite powder, 1.5-2% of calcium dihydrogen phosphate, 0.8-1.5% of premix, 0.05-0.15% of lysine sulphate, 0.1-0.3% of table salt, 0.1-0.3% of choline and 0.01-0.03% of an anti-oxidant. The fry nutrition powder has a composite formula, is prepared from a plurality of raw materials, contains comprehensive nutrients, satisfies nutrition requirements of roe from algae bloom growth to blooming in summer, is conducive to fry growth, greatly saves culture labor, reduces labor intensity and improves a fry survival rate.

Description

1. Technical field [0001] The invention belongs to a feed production technology, in particular to a fry nutrition powder and a preparation method thereof. 2. Background technology [0002] Fish fry cultivation refers to the summer flower fish species with a body length of about 3 cm after about 25 days in the pond under the water flower. Due to the small fry, delicate constitution, poor mobility, narrow feeding range, low feeding ability and high metabolism level, they are very sensitive to changes in the external environment. Therefore, the cultivation of fry to summer flowers must be carefully fed and carefully operated to create a favorable ecological environment suitable for the growth of fry. At present, farmers mainly use soybean milk for feeding during the water flower to summer flower stage of seedlings, and generally start feeding soybean milk half a day after the fish fry enter the pond. Soak the soybeans in water first, and soak them for 6 hours at a water temp...

AI Technical Summary

Problems solved by technology

The main problem is that it takes time and labor to grind soybean milk every day; the nutrition of soybean milk itself is not as comprehensive as that of full-price compound feed; the temperature for preparing soybean milk is up to 90°C, the soybeans are not fully matured, and there are many anti-nutritional factors.
