Feed for tilapia in breeding season

Abstract

The invention relates to the field of feed, in particular to feed for tilapia in a breeding season. The feed comprises components in parts by weight as follows: 2-8 parts of locust tree leaf 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, radix scutellariae, cortex acanthopanacis, medicated leaven, malt, andrographis paniculata, radix codonopsis, angelica sinensis, fructus psoraleae, semen cuscutae, radix paeoniae alba, eucommia ulmoides, longspur epimedium, fenugreek and bentonite. The feed for the tilapia in the breeding season has the beneficial effects that the death rate of the female tilapia fed on the feed is very low, the spawning rate of the tilapia fed on the feed is 21.08% higher than that of tilapia fed on normal feed, and thus the feed can greatly improve both the spawning amount of the tilapia and health conditions of the female tilapia in the breeding season, and is suitable for being used for feeding of the tilapia in the breeding season.

Description

technical field [0001] The invention relates to the field of feed, in particular to a feed for tilapia in the breeding period. Background technique [0002] Tilapia, commonly known as: African tilapia, is a small and medium-sized fish. Now it is a freshwater farmed fish cultivated by key scientific research in the world's aquaculture industry, and it is known as one of the main sources of animal protein in the future. Native to Africa, it is a tropical fish belonging to the family Cichlidae, similar to perch. Usually live in fresh water, can also live in salt water with different salinity, and can also survive in shallow water of lakes, rivers, and ponds. It has strong adaptability and can reproduce in small waters, even in rice fields, and has strong adaptability to water with less dissolved oxygen. Most tilapia are omnivorous, often eating plants and debris in the water. [0003] The meat of tilapia is delicious and tender, whether it is braised or cooked, it tastes go...

Problems solved by technology

[0004] Due to the above advantages and characteristics, more and more tilapias are artificially raised and propagated. They need more nutrition during the breeding period, and their physique is weak during the breeding period, so they are easily affected by external bacteria, fungi and parasites. The number of fish eggs is small, resulting in hindered reproduction, and even the death of the female fish, which affects economic benefits, and the current tilapia feed on the market does not have feed for the breeding period, which is a deficiency in the prior art
