Special compound feed for pseudobagrus ussuriensis fries and advanced fries and a preparation method thereof

Abstract

The present invention relates to feed for pseudobagrus ussuriensis fries and advanced fries, and belongs to the field of special compound feed and processing thereof. The special compound feed is good in palatability, balanced in nutrition, easily available in raw materials and pollution-free in aquaculture water body, and can improve the immunity of pseudobagrus ussuriensis fries and advanced fries. The feed is characterized in that the feed consists of the following ingredients in mass percentages: fish meal 30-40%, daphnia powder 20-30%, meat and bone meal 10-15%, full-fat soybean 10-15%, cottonseed meal 2-5%, beer yeast 2-5%, flour 1-7.5%, 1% calcium dihydrogen phosphate 1%, compound enzyme preparation 0.5%, immunopotentiator 0.5%, garlicin 0.01%, choline chloride 0.3%, liver and gallbladder Kang 0.5%, multi-vitamin premix 0.5% and multi-mineral premix 0.5%. The preparation process includes: raw material crushing, mixing, extruding and granulating. The feed is simple in process, balanced in nutrition and easily available in raw materials, and solves the problems of pollution in the aquaculture water body and poor disease resistance of the fish body.

Description

(1) Technical field [0001] The invention relates to a compound feed for larvae Ussuri juveniles and a preparation method thereof, in particular to a compound feed suitable for the cultivation of larvae Ussuri juveniles and belongs to the field of compound feed and its processing. (2) Background technology [0002] Ussuriensis (Pseudobagras ussuriensis), formerly known as Ussuriensis and local name of oxtail, belongs to Siluriformes and Pleuridae fishes, and is a unique fish distributed in the Heilongjiang River Basin of my country. Its meat is tender and tender without intercostal thorns. It tastes particularly delicious and has high nutritional value. It is an excellent delicacy in high-end restaurants and has high economic value. Due to the change of environment and the impact of human activities, the natural yield has declined significantly, and its population resources in Heilongjiang are facing exhaustion. Only the tributary Wusuli River still has a certain population, ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are few developments and developments of proprietary compound feeds for the breeding and production of Ussuri catfish. There is only one invention patent (ZL 201010293844.1) developed by members of our research group on the basis of a large number of nutritional and physiological experiments. This patent is aimed at about 10g For the rearing of juvenile fish, so far, there is no special feed suitable for the growth of Ussuri larvae juveniles. Farms generally use water flea powder or live waterworms for feeding. This feeding method will lead to feed Many unfavorable factors such as low efficiency, slow growth rate, heavy water pollution, and poor disease resistance not only increase the cost of breeding, but also increase the difficulty of breeding production and operation.
