Method for increasing reproduction performance of sows

Abstract

The invention discloses a method for increasing the reproduction performance of sows. Food consumption is limited at the age of 4 to 5 months, mating is carried out at the age of 6 to 7 months, illumination is carried out one month before mating, the fertilization of sows is divided into two stages from the beginning, the first stage is from the first day to the 59th day, the second stage is from the 60th day to farrowing, and feed A and feed B are respectively fed; rock-and-roll and light music are adopted in two weeks before farrowing, light music is adopted after farrowing, the lactating sows are mated again one week after weaning, and the steps starting from mating are repeated until elimination. The method disclosed by the invention is green, energy-saving and environment-friendly, can prevent diseases, increases the reproduction performance of sows, and increases the economic benefit of pig farms.

Description

technical field [0001] The invention relates to the field of breeding, in particular to a method for improving the reproductive performance of sows. Background technique [0002] Sow feeding is one of the most important links in pig production. Its nutritional status not only directly affects the health and production performance of piglets, but also affects the reproductive life of sows and the efficiency of pig production. In the modern pig breeding system, prenatal feeding of sows is crucial to the subsequent reproductive performance of sows. At this time, although sows are sexually mature, they have not yet reached physical maturity, and are easily affected by factors such as disease, management, and feeding. low. The reproductive performance of sows directly affects the production performance of commercial intensive pig farming. SUMMARY OF THE INVENTION [0003] In order to overcome the above deficiencies, the present invention provides a method for improving the re...
