Problems solved by technology

[0004] At present, there are few studies on the estrus rate of weaned sows in the prior art, most of which only focus on feed, and cannot be adjusted according to the body changes of weaned sows, ignoring the environment of weaned sows, the effect is not satisfactory

Embodiment 1

[0037] A method for improving the estrus rate of weaned sows, comprising the following steps:

[0038] a. Weaning of sows: sows are weaned into the positioning pen according to the weaning age of suckling piglets, and the weaning age is 21 days;

[0039] b. Weaning management: Feed the sows on the day of weaning, supplement sugar 180g / head / day, and set up a lighting supplementary system in the weaning school building. From the day of weaning to the completion of breeding, every morning 5:30-10:00 and 17:00 pm 30-22:00 Use light to supplement light on the barn;

Abstract

The invention relates to the technical field of weaning sow feeding, in particular to a method for increasing the estrus rate of weaning sows. The method of the present invention mainly comprises: a. weaning of sows: weaning of sows is weaned according to the age of suckling piglets and enters the positioning bar for weaning, and the age of weaning is 21-28 days; b. weaning management: feeding sows feed on the day of weaning , add sugar every day, and set up a lighting supplementary system in the weaning school building to supplement the light; c. Trial mating: use different boars to trial mating every day, mating sows after estrus, and feeding gestational feed on the day after mating; d. Weaning sows Sows that have not been in estrus for ≥8 days are reared in groups from the positioning pen to the weaning pen. The invention provides a method for increasing the estrus rate of weaned sows, which is designed according to the body changes of the weaned sows, effectively shortens the estrus time of the weaned sows, improves the physique of the weaned sows, and increases the estrus rate and pregnancy success rate within 7 days.

Description

technical field [0001] The invention relates to the technical field of weaning sow feeding, in particular to a method for increasing the estrus rate of weaning sows. Background technique [0002] At present, in terms of professional breeding enterprises that provide high-quality breeding pigs, sow feeding is one of the most important links in breeding production. In pig production, delayed estrus or no estrus after weaning is a common problem in recent years and has been affecting the pig industry. For large-scale breeding pig farms, the estrus rate of sows after weaning directly affects the production cost and production performance of the whole pig farm. Number of pigs born and litter size. In some pig farms, about 20% of sows are eliminated for this reason, which causes great economic losses to pig production. Shortening the interval between weaning sows and estrus again has become the most concerned and most urgent technical problem in pig farms. [0003] From weanin...
