Feed for juvenile black carps

Abstract

The invention relates to the field of feed, particularly to feed for juvenile black carps. The feed comprises the components in parts by weight as follows: 30-40 parts of green hay powder, 20-30 parts of cottonseed cake powder, 10-15 parts of soybean cake powder, 5-10 parts of rape seed cake powder, 5-10 parts of silkworm chrysalis meal, 5-10 parts of fish meal, 5-10 parts of barley flour, 0.1-1.0 part of multivitamins, 1-5 parts of a traditional Chinese medicine additive and 1-2 parts of mineral salt, wherein the traditional Chinese medicine additive comprises the components as follows: honeysuckle, rhubarb, garlic, pilose asiabell roots, manyprickle acanthopanax roots, silktree albizzia bark, coptis roots, radix astragali, fructus aristolochiae, blackberrylily rhizomes, tobacco, humifuse euphorbia herb, Chinese gall, Chinaberry roots, amur cork tree bark, medicated leaven, poria cocos, bentonite and malt. The feed has the benefits as follows: with the adoption of the feed, the survival rate of the black carps and the weight of adult black carps are increased effectively, the survival rate is up to 99.33%, the weight growth rate is also up to 55.59%, the feed coefficient is reduced, the conversion rate of the feed is increased, the cost is reduced, and the benefit is increased.

Description

technical field [0001] The invention relates to the field of feed, in particular to a young herring feed. Background technique [0002] Herring is a fish with a green color, mainly distributed in the plains south of the Yangtze River in my country, and relatively rare in the north of the Yangtze River; it is an important fishery resource in the middle and lower reaches of the Yangtze River and lakes along the river and the main breeding object in lakes and ponds , is one of the "Four Great Fishes" in freshwater farming in my country, and herring grows the fastest among the "Four Great Fishes". Jiangxi Hukou herring grows fastest at the age of 1 to 4, with an average annual weight gain of more than 3.7 kg at the age of 5 to 6. The average annual weight gain of male fish is about 1 kg less than that of female fish, so more and more of them are farmed. However, because juvenile fish are not fully developed in terms of physiology and immunity, there is no matching feed for prote...

AI Technical Summary

Problems solved by technology

The average annual weight gain of male fish is about 1 kg less than that of female fish, so more and more of them are farmed. However, because juvenile fish are not fully developed in terms of physiology and immunity, there is no matching feed for protection. Therefore, due to diseases such as herring enteritis, the survival rate of juvenile fish is low, and the weight of adult fish is low and the quality of fish meat is poor due to the poor development of adult fish when they are juvenile fish. Therefore, a feed suitable for juvenile herring is needed
