Oil meal for improving breading stock reproductive performance and preparation method thereof

Abstract

The invention discloses oil meal for improving breading stock reproductive performance and a preparation method thereof, and the oil meal comprises the following components by weight: 25-35% of fish oil; 10-20% of emulsified soya-bean oil; 8-12% of maize germ oil; 30-40% of ripe maize; 8-10% of cereal protein; 0.5-1.5% of beta-carotene; 0.05% of antioxidants; the method for preparing the oil meal for improving breading stock reproductive performance comprises the following steps: performing crushing and ripening treatment of the maize firstly; weighing the raw materials according to the formula, well mixing, performing dust-free emulsification, homogenization, and spray drying of the mixed materials; well mixing the dried materials and the ripe maize powder according to the formula, cooling, packaging, performing acceptance inspection and warehousing.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to an oil powder capable of improving the reproductive performance of breeding stock and a preparation method thereof. Background technique [0002] Fat is an important nutritional component, but the needs of animals at different stages are different. Breeding animals require different fatty acid compositions for reproductive functions such as egg production, sperm production, fertilization, implantation, and fetal development. For example, boars need a lot of vitamins, organic selenium, amino acids required for sperm production, omega-3 fatty acids, etc. during breeding; sows need nutrients such as VE, VC, folic acid, biotin and natural vitamins. [0003] At present, there are few feeds specially used for breeding animals in China, especially the oil powder specially used for breeding animals is even rarer. Most feed manufacturers use oil as an energy supplement. The quality of oil u...

AI Technical Summary

Problems solved by technology

Most feed manufacturers use oil as an energy supplement. The quality of oil used for feed in the market is unstable, which can easily lead to oxidation and deterioration, reduce animal digestion and absorption rate, and unbalanced fatty acid composition

This will lead to the inability of the fat to be chymed, and the efficiency of digestion and absorption is low; the essential fatty acids contained in it are also unbalanced, which does not meet the nutritional needs of animals, and is contrary to the scientific feeding concept advocated now.
