Problems solved by technology

[0004] However, after using special feed for gilts in some pig farms, the breeding rate of gilts has not been significantly improved. It means that although the gilt has entered the estrus period, it does not have a static reaction, which will make it difficult for the breeder to judge whether the gilt is in estrus when checking the estrus, and miss the best mating time, thereby reducing the breeding rate of the gilt. The invention for this problem has not been reported at present

Abstract

The invention relates to feed additives capable of improving heat behaviors of replacement gilts. The feed additives comprise soy isoflavone, pueraria extracts, dye genistein, fructose and glucose. The feed additives are reasonable and innovative in formula and conform to growth, development and physiological characteristics of the replacement gilts; after application of the feed additives, silent heat rate of the replacement gilts is remarkably declined, the heat behaviors are improved, and breeding rate of the replacement gilts is increased while cost is low and the feed additives comply with actual production of a pig farm.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a feed additive for improving the estrus performance of gilts. Background technique [0002] The cultivation of gilts is the basis for the expansion of reproduction in pig farms. Only by cultivating excellent gilts can an excellent production sow herd be built. The estrus of gilts is an important marker of the conception ability and screening of gilts. Timely confirmation of gilts with reproductive ability can improve the screening efficiency of gilts, and effective treatment of non-estrus gilts can greatly improve the gilts' fertility. The breeding rate of sows can be reduced, the feeding amount and feeding cost of gilts can be reduced, and the overall benefit of the pig farm can be improved. The estrus rate of gilts is an important indicator to measure the breeding performance of gilts. Improper nutrition and feeding programs lead to low breeding success rate of gilts, and they...
