Method for increasing oestrus breeding rate of replacement gilts

Abstract

The invention discloses a method for increasing the oestrus breeding rate of replacement gilts. The method includes the steps of breeding gilt selection, nutrient matching, feed mildewing, illumination control, temperature, humidity and ventilation control, and replacement gilt raising. In the method, vaccine immunity and drug health care should be performed; green fodder should be provided; driving movement, swinery changing, swinery combination and vehicle carrying movement should be performed; oestrus inducing should be performed; recording and short-time high-quality raising should be performed; breeding age in days and weight should be reasonable; concentrated oestrus breeding should be performed. Hormone oestrus promotion, Chinese herbal medicine oestrus promotion, starvation treatment and brown sugar oestrus promotion are performed on the anestrus replacement gilts. According to the invested cost of the method, 5166 replacement gilts are purchased this year, PG 600 needs to be used for 20% of the replacement gilts for oestrus promotion, the cost of the PG 600 used for each replacement gilt is 43 RMB, and the drug cost is 44427.60 RMB; according to the output value, after conventional treatment measures and oestrus promotion of PG 600, the oestrus breeding rate reaches 94.12%. 5166 replacement gilts are introduced, and supposing that the overall oestrus breeding rate is 93%, the standard oestrus breeding rate of the replacement gilts is 90%; the anestrus replacement gilts are sold, and supposing that each replacement gilt is 130 kg and each kg of the replacement gilts is 12 RMB, 411213.60 RMB of loss is reduced.

Description

technical field [0001] The invention relates to a method for increasing the mating rate of sows, in particular to a method for increasing the mating rate of gilts in estrus. Background technique [0002] In intensive pig farms, because of the production according to the plan and process, a large number of gilts must be replenished every year. However, following that, the low mating rate of gilts in estrus is another headache. How to aphrodisiac aphrodisiac gilts to increase their estrus mating rate has also become one of the problems that pig farms must face and solve. Contents of the invention [0003] The purpose of the present invention is to provide a method for improving the estrus mating rate of gilts. [0004] This method of increasing the mating rate of gilts in estrus: [0005] ① Seed selection: From a genetic point of view, the estrus of gilts has a certain correlation with their mothers. Estrus, but indirectly from the perspective of maternal reproductive pe...
