Problems solved by technology

However, the reproductive performance of foreign boars raised in intensive pig farms is poor, which has become an unsolved bottleneck in the development of the pig industry. Therefore, it is of great significance to research and develop feed additives to improve the reproductive performance of boars.

Embodiment 1

[0020] Adopt the preparation method of the feed additive that improves boar reproductive performance of the present invention to prepare this feed additive, get raw material 57.9kg altogether, the weight of each raw material is respectively: pine needle 44kg, malt 4kg, silkworm chrysalis 2kg, epimedium 1kg, actinolite 1kg, dodder 4kg, arginine 1kg, amino acid chelated zinc 0.8kg, vitamin E 0.1kg. The above-mentioned ingredients are mixed, ultrafinely pulverized, evenly stirred, and packaged to obtain the finished feed additive, and the particle size diameter of the finished product is less than 10 μm (that is, more than 300 mesh).

[0021] Using the feed additives prepared by the above method to improve the reproductive performance of boars, the company conducted a feeding test of boars in a large breeding pig farm in Yangzhong, Zhenjiang. Eight Duroc boars in use with clinical health and basically the same constitution were selected and randomly divided into 2 groups, with 2 ...

Abstract

The invention provides a feed additive for improving the reproductive performance of a boar. The feed additive is prepared from the following components in parts by weight of 440-460 parts of pine needles, 40-60 parts of malt, 20-30 parts of silkworm chrysalis, 10-20 parts of herba epimedii, 10-20 parts of actinolite, 40-60 parts of semen cuscutae, 10-20 parts of arginine, 8-12 parts of amino acid chelated zinc and 1-3 parts of vitamin E by virtue of mixing, superfine grinding, uniform mixing and sub-packaging. The particle size of the finished feed additive is less than 10 microns (namely above 300 meshes). The feed additive provided by the invention is high in safety, low in use cost, and relatively good in palatability; the feed additive is added in the ration of the boar according to the quantity of 0.1 percent, the duration of the ejaculation of the boar can be remarkably prolonged, the density and the vitality of the sperms of the boar are improved, and thus the ideal feed additive is used for improving the reproductive performance of the boar.

Description

technical field [0001] The invention relates to a feed additive for improving the reproductive performance of boars, belonging to the field of feed additives. Background technique [0002] As the saying goes, "It's a good litter for sows, and a good slope for boars." It can be seen how important the reproductive performance of boars is. The purpose of breeding boars is to have a healthy body, strong libido and good breeding ability, and to be able to produce a large number, high density, and good quality semen. However, the reproductive performance of foreign boars raised in intensive pig farms is poor, which has become a bottleneck to be solved in the development of pig industry. Therefore, it is of great significance to research and develop feed additives to improve the reproductive performance of boars. Contents of the invention [0003] The purpose of the present invention is to adopt modern feed additive processing technology, use pine needles, malt, silkworm chrysa...
