In summer, the climate is hot and the temperature on the farm is relatively high. Doing heatstroke prevention work effectively reduces the occurrence of epidemics. Breeding experts introduced that in the high temperature season, different feeding and management should be given according to different types of pigs and different physiological stages of pigs.

Boars Feed twice a day and feed green feed or thinner at noon. Breeding and exercise are performed in the morning and evening. Do not spray or spray cold water immediately after the breeding. From 1 pm to 3 pm every day, water is sprayed on the pigs and the ground once, and the light is reduced to 8 to 10 hours. If the number of breedings is small, the amount of fine feed should be reduced to prevent over-fertilization and poor libido.

2. Pregnant sows. Avoid breeding breeding in the hot season, sows in the pre-pregnancy period (0 to 84 days) should be dominated by green coarse materials, with appropriate concentrates, to reduce the rearing density, raising 2 to 3 heads in each circle. In the second trimester of pregnancy and during the lactation period, the pig should concentrate on the raw material to match the green material. The coarse material can be fed without feeding, and the feed can be fed 3 times a day. Add 1% to 1.5% baking soda, 0.3% salt.

3. Pregnant sows. The summer delivery room should be well-ventilated and have shading facilities. The production mothers should reduce the concentrates 2 to 3 days before the onset of labor, and feed more green materials. The ratio of bran in the concentrates should be increased. The purpose of the bowel against constipation is to feed the bran warm brine once after the piglets have been produced.

4. Goods pig. It is difficult to raise in high temperature seasons, often appear not to eat food, affecting growth. Generally, fat pigs are sold before the high temperature season has passed. If they are not for sale, the stocking density should be reduced, and a few heads per lap should be kept. Each pig occupies a circle area of ​​1 to 1.2 square meters. Water spray cooling, feed sooner or later, at noon plus green feed or thin material, the material plus sodium bicarbonate 1.5%, salt 0.3%.

5. Suckling piglets and piglets. Hi lying on the wet ground, pay attention to changes in the weather to prevent cold pulling or diarrhea. Keep the dough dry, clean drinking water, often disinfected. Prevention can be used per kilogram of material plus 120 milligrams of oxytetracycline for several days and several days of treatment, with oxytetracycline 200 milligrams per kilogram.
