Feed additive capable of improving reproductive performance and reproductive life of boar

Abstract

The invention discloses a feed additive capable of improving reproductive performance and reproductive life of a boar. The feed additive is prepared from the following components by weight percent of 8-15% of total fat, 0.3-1% of timnodonic acid and docosahexaenoic acid, 2-8% of lysine, methionine, tryptophan, and threonine, 2-5% of enveloped glutamic acid, 2.5-10% of arginine, 0.4-1% of isoleucine, 0.5-4.5% of leucine, 5-12% of fructose, 0.1-1% of L-carnitine, 0.1-1% of vitamin E, 1-5% of vitamin C, 0.001-0.1% of organic selenium, and 0.1-0.8% of organic zinc and inorganic zinc, wherein the ratio of kestose to nystose to pentasaccharide is 1 to (2-2.5) to (1.8-2.2), and the ratio of the organic zinc to the inorganic zinc is 1 to (1.2-1.8). The additive disclosed by the invention can promote the health and the function of the reproductive organ of the boar, and maintains the reproductive performance and the reproductive life of the boar.

Description

technical field [0001] The invention relates to a feed additive which is beneficial to the reproductive performance and reproductive lifespan of boars. Background technique [0002] In the process of intensive pig production, the semen production of boars decreases, the sperm motility is low, the quality of semen is low, and the occurrence of high boar elimination rate is very common, especially in pig farms with poor breeding conditions and low breeding levels. The elimination rate of boars caused by low libido, semen production and semen quality problems can reach about 30%-50%, which increases the input cost of the farm and seriously restricts the sustainable development of the pig farm. Animal cell membrane phospholipids contain a large amount of fatty acids, especially monounsaturated fatty acids and polyunsaturated fatty acids, which play an important role in the normal physiological functions of cell membranes. Poulos et al. (1986) detected long-chain polyunsaturated...

Problems solved by technology

However, at present, there is a lack of data on adding fructose to boar diets, and because there are many types of fructose, the appropriate ratio between different types of fructose, such as fructobiose, fructotriose, and fructotetraose, is even more scarce. This patent proposes the appropriate level of adding fructose in the diet of boars through many years of practice and testing, and determines the appropriate ratio between different types of fructose, which greatly improves the semen quality and quality of boars. breeding power
