When the temperature rises to 35°C, pigs use less feed and have lower weight gain. Therefore, the high temperature season should be based on different types of pigs and different physiological stages of the pig to give different feeding methods.
Boars are fed twice a day and green feed or thinner is added at noon. Breeding and sports are performed in the morning and evening when cool, and do not allow them to immediately spray water or spray cold water on the body after breeding. Every day from 1 to 3 o'clock in the afternoon, water is sprayed on the pig body and the ground once, and the light is controlled for 8 to 10 hours. If the number of breeding is small, the amount of concentrate feeding should be reduced to prevent it from becoming over-fertilized and having poor libido.
Pregnancy sows pregnant sows should be based on roughage, with the appropriate material, reduce the breeding density, raising 2 to 3 per circle. Late pregnancy and lactation require 1 pig 1 lap, mainly to concentrate feed properly with green feed, can not feed roughage, feed 3 times a day, in the middle plus feed thinner, water spray 1, the material plus 1% to 1.5% Baking soda, 0.3% salt. In addition, avoid breeding at high temperatures.
In the high-temperature season of commercial pigs, there is often a phenomenon of inverted trough and no eating, which affects growth. It is generally sold before the arrival of the hot season, and if not sold, the stocking density should be reduced.
Nursing pigs and pigs prefer lying and wet ground, pay attention to changes in the weather, to prevent it from pulling cold or diarrhea.
