Problems solved by technology

The current feed used in the cultivation of Channaidae fish is designed according to the feed formula of carnivorous fish in seawater, which mainly has problems such as poor palatability, high feed coefficient, and slow growth rate.
There is no extruded compound feed for Channaidae fish to improve the palatability of feed and the growth rate of farmed fish.

Abstract

The invention relates to a formula of compound puffed feed for snakehead mullet and process for preparation, wherein the constituents in the formula comprise (by mass ratio): fish meal 35-50%, fermented soybean waste 10-20%, meat and bones meal 0-12%, silkworm chrysalis powder 0-5%, blood powder 0-5%, brewer's yeast 2-5%, shrimp grease 0-6%, fish oil 1.0-3%, high grade flour 10-20%, liquid phosphatide 1-2%, calcium dihydrogenphoshate 0.5-1.5%, composite vitamin 0.5-1%, compound minerals 0.5-1%, choline chloride 0.3-0.5%. The preparing process consists of proportioning constituents, mixing homogeneously, disintegrating, modulating, palletizing and drying.

Description

【Technical field】 [0001] The invention belongs to the field of feed for snakehead fish and a preparation method thereof, and in particular relates to a formula and a preparation method of an extruded compound feed for snakehead fish. 【Background technique】 [0002] There are only two genera and 8 species of snakeheads in my country, among which snakeheads and snakeheads have become important economic fish in freshwater aquaculture in my country. The meat of the snakehead is delicate, delicious, with fewer thorns and more meat, and rich in nutritional value. It has medicinal functions such as removing blood stasis and promoting body fluid, nourishing and recuperating, removing dampness and diuresis, promoting muscle and blood, and healing wounds. Channa, also known as Seven Star Fish, is a hot-selling aquatic product in the markets of Guangdong, Hong Kong, Macao and Southeast Asian countries, and it is also a famous and high-quality aquatic product that earns foreign exchange...
