Special concentrated feed for anti-heat stress breeding boars

Abstract

The invention relates to special concentrated feed for anti-heat stress breeding boars, and belongs to the technical field of livestock feeds. The special concentrated feed for anti-heat stress breeding boars is prepared from high protein soybean meal, small peptide protein, steam fish meal, dietary fiber, emulsified fatty powder, soybean oil, mountain flour, calcium hydrophosphate, sodium chloride, glucose, lysine, N-carbamylglutamic acid, composite inorganic trace elements, composite organic trace elements, decavitamin, vitamin E, vitamin C, probiotics, choline chloride, macleaya cordata extracts, phytase and antioxidants. The special concentrated feed has the advantages that the cooperated effect of the recipe ingredients are emphasized; the physiological requirements of breeding boars under the heat stress condition can be met; the sperm viability is improved; the rate of teratosperm is reduced; the palatability is improved; under the multiplex nutrition measures, the semen quality of the breeding boars under the heat stress condition is effectively improved; the re-service rate of sows is reduced; and the annual farrowing number of the sows can be improved.

Description

technical field [0001] The invention belongs to the technical field of livestock feed, and in particular relates to a special concentrated feed for anti-heat stress type breeding boars. Background technique [0002] Breeding boars are one of the most important means of production in the modern intensive pig farming industry, but the number only accounts for about 2% of the number of breeding pigs. In the current large-scale breeding, the activity places of boars are greatly restricted, and the task of mating is quite heavy. The semen production of boars decreases, the quality of semen is low, and the elimination rate of breeding boars is very common. Especially in summer (July-August) due to the impact of high temperature and heat stress, boar studs often have problems such as low libido, insufficient semen collection, low sperm motility, and high deformity rate. [0003] Due to the small number of stocks, the nutritional problems of boars have not received enough attention...

AI Technical Summary

Problems solved by technology

In the current large-scale breeding, the activity places of boars are greatly restricted, and the task of mating is quite heavy. The semen production of boars decreases, the quality of semen is low, and the elimination rate of breeding boars is very common.

Especially in summer (July-August), due to the impact of high temperature and heat stress, boar studs often have problems such as low libido, insufficient semen collection, low sperm motility, and high deformity rate.

[0003] Due to the small number of stocks, the nutritional problems of boars have not received enough attention, and there is very little research in this area. There is even a lack of high-quality feed for boars on the market. Many pig farms use feed for pregnant sows or fattening pigs. Feeding boars with feed, without considering the special physiological needs of boars under high temperature conditions, resulting in poor semen quality and degraded reproductive performance of boars, which directly affects the economic benefits of pig farms
