Feed for black carp in breeding season

Abstract

The invention relates to the field of feed, in particular to feed for black carp in a breeding season. The feed comprises components in parts by weight as follows: 30-40 parts of green hay meal, 15-25 parts of fish meal, 20-30 parts of rapeseed meal, 10-15 parts of corn flour, 20-30 parts of bran, 10-15 parts of wheat middling and red dog, 10-15 parts of kelp meal, 0.1-0.5 parts of manganese sulfate, 0.1-0.5 parts of ferric sulfate, 0.1-1.0 part of multivitamins, 1-5 parts of traditional Chinese medicine additives and 1-2 parts of mineral salts. The traditional Chinese medicine additives include the following components: herba houttuyniae, garlic, herba violae, honeysuckle, solidago, fleece-flower roots, atractylodes, radix scutellariae, cortex acanthopanacis, medicated leaven, malt, andrographis paniculata, radix codonopsis, angelica sinensis, semen cuscutae, radix paeoniae alba, eucommia ulmoides, curculigo orchioides and bentonite. The feed for the black carp in the breeding season has the beneficial effects that the death rate of the female black carp fed on the feed is very low, the spawning rate of the black carp fed on the feed is 16.46% higher than that of black carp fed on normal feed, and thus the feed can greatly improve both the spawning amount of the black carp and health conditions of the female black carp in the breeding season, and is suitable for being used for feeding of the black carp in the breeding season.

Description

technical field [0001] The invention relates to the field of feed, in particular to a breeding 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. They need more nutrition during the breeding period, and their physique is weak during the breeding period, so they are vuln...

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. They need more nutrition during the breeding period, and their physique is weak during the breeding period, so they are vulnerable to external bacteria, fungi and parasites. The impact of insects makes the number of fish eggs small, resulting in hindered reproduction, and even causes the death of the female fish, which affects economic benefits, and the herring feed currently on the market does not have feed for the breeding period, which is one of the deficiencies in the prior art. place
