Compound feed capable of improving reproductive capacity of Oreochromis niloticus parent fish and preparation method thereof

Abstract

The invention discloses a compound feed capable of improving the reproductive capacity of Oreochromis niloticus parent fish and a preparation method thereof. The compound feed can obviously improve the reproductive capacity of Oreochromis niloticus parent fish and reinforce the disease resistance. The feed comprises the following ingredients in percentage by weight: fish meal 5-15%, soybean meal 10-30%, dephenolized cottonseed meal 5-15%, double-low rapeseed meal 10-20%, high-gluten flour 10-30%, corn protein powder 5-10%, rice bran 10-20%, phosphatide oil 0.5-1%, soybean oil 1-3%, compound vitamins 0.2-0.5%, compound minerals 1.0-2.0%, phagostimulant 0.3-1.0%, vitamin C phosphate 0.1-0.3%, calcium dihydrogen phosphate 1-3%, anti-mildew agent 0.01-0.05%, Temianhuang 0.2-0.8%, choline chloride 0.05-0.15%, and vitamin E 0.01-0.03%. The feed and the preparation method thereof belong to the technical field of aquatic feeds.

Description

technical field [0001] The invention relates to a compound feed for aquatic animals, in particular to a compound feed for improving the fecundity of Gifu tilapia, and belongs to the technical field of fish feed. Background technique [0002] Tilapia (Oreochromis mossambicus) belongs to the order Perciformes, the family Cichlidae, and the genus Tilapia. It is a high-quality fish species recommended by the United Nations Food and Agriculture Organization (FAO) to the world, and it is also the main aquaculture species in my country. According to the 2013 China Fishery Statistical Yearbook, the national tilapia production has reached 1.55 million tons. Gifu tilapia is a genetically improved Nile tilapia. It is a fish with high nutritional value and economic value. It has become the main aquaculture species in South China. [0003] With the continuous expansion of tilapia farming scale, the quality of seed has gradually attracted the attention of farmers. In order to obtain a ...

AI Technical Summary

Problems solved by technology

At present, most tilapia nursery farms in my country use artificial hatching to hatch fertilized eggs. Although the reproductive cycle is greatly shortened and the number of spawning is increased, more nutrients in the broodstock are used for sex cell development, resulting in a serious decline in the broodstock physique. , a series of problems such as weakened fecundity and reduced egg production

However, there are very few studies on nutrition and feed for broodstock of Gifu tilapia, and there is no special compound feed for it in the domestic market, which seriously hinders the development of tilapia nursery industry
