How to ensure the success rate of breeding pigs in summer

High temperature in summer will bring great trouble to sow breeding, one of which is the decline in the success rate of sow breeding, and summer is also the peak period of disease, which can easily lead to abortion and stillbirth in sows. So how do farmers take measures to improve the success rate of pig breeding in summer? Let's get to know it with the editor.

1. Reasons for the low success rate of mating in summer

1. The summer temperature is hot and the ambient temperature of the pigsty is too high, which will reduce the libido of boars, reduce the vitality of semen, thin semen, and increase the number of dead semen and weak semen. In addition, the lack of nutrition intake for sow reproduction will also lead to irregular estrus and ovulation, which is also one of the main reasons for the low success rate of sow breeding in summer.

2. In summer, pigs are easily infected with Japanese encephalitis. Boars are mainly characterized by orchitis, decreased sexual function and decreased semen mating. Sows infected with Japanese encephalitis will show difficulties in mating, abortion, stillbirth and so on. In addition, when the transport volume of breeding pigs is small, there will also be the phenomenon of hindlimb weakness, which is also an important factor in the difficulty of breeding.

II. Solutions

1. Control temperature

Summer is hot and hot, so the first thing to do is to control the temperature, you can do a good job of cooling and heat prevention by cooling according to the fan or spray cooling and other equipment.

2. Adjust the feed

Pigs have a loss of appetite in summer, so it is necessary to timely change the proportion of feed, to feed green feed, to change the feeding time, and to avoid feeding at noon. You can choose to feed when the temperature is lower in the morning and evening, when the temperature is lower. Pigs have a better appetite and can take in enough nutrients. In addition, to supply clean and cool drinking water, multi-dimensional compound electrolysis can be added to drinking water to supplement vitamin deficiency.

3. Do a good job in sow health care

Especially in perinatal sow health care, broad-spectrum antibiotics were added to sow feed one week before and after parturition to purify sow disease. In addition, sows should maintain proper exercise during pregnancy, which is conducive to delivery and reduce stillbirths and miscarriages.

4. Adjust the mating time

High temperature in summer, boar's libido is low, semen quality is poor, so the mating time can be adjusted appropriately, the morning and evening mating will be adjusted at night, the evening temperature is lower, the boar's libido is high, the semen quality is high, and the success rate of mating is also relatively high.
