Precautions for raising pigs in summer: pigs should also prevent heatstroke and cool down. With the development of pig industry, scientific pig raising is gradually popularized. In order to raise pigs well, all factors affecting the rapid growth of pigs should be fully considered. In hot summer, it is also a key link to do a good job of heatstroke prevention and cooling for pigs. Because temperature has a very important influence on the growth and development of pigs, the most suitable growth temperature for pigs is 18-25℃. In this temperature range, the feed utilization rate of pigs is high and the weight gain is fast. If the ambient temperature is too high, the feed utilization rate of pigs will be reduced, the growth will be slow, or even stop. Moreover, pigs are prone to heatstroke in hot summer. Therefore, in the process of raising pigs.

1, pigsty construction should be scientific and reasonable. The pigsty should be built in a ventilated and open place, and the thermal insulation performance should be fully considered when selecting building materials, such as hollow bricks for building walls and thermal insulation for building ceilings.

2. Do a good job of shading the pigsty. In order to do a good job in greening the environment around the pigsty, we can plant some lush plants, such as planting some fast-growing poplars in the east and south of the pigsty, and planting some creepers and grapes on the back, so as to avoid direct sunlight, reduce thermal radiation and achieve the purpose of cooling down.

3. The pigsty should have sufficient water supply. In hot weather, spray pigsty and pig's body with cold water, and supply enough drinking water. If possible, it is best to use automatic drinking water equipment and ventilate the pigsty to make the pigsty air circulate.

4. Control the density of pigs in the house. Because the breeding density directly affects the temperature of the pigsty, it is better to reduce the breeding density of pigs in high temperature season, and it is better for fattening pigs to occupy more than 1 square meter. Excessive density affects the feed intake of pigs and slows down the weight gain.

5. Improve the dietary nutrition level and adjust the feeding methods. Under the condition of high temperature, the appetite and feed intake of pigs decreased, which directly affected the growth needs of pigs. Therefore, it is necessary to improve the nutritional level of the diet at high temperature, and at the same time adjust the feeding methods, so that pigs can eat well in the morning and evening in cold weather, and give a certain amount of green feed at noon in hot weather to supplement nutrition and play a role in cooling down.

6. Prevent the occurrence of thermal stress in time. Fattening pigs are sensitive to heat. In hot summer, adding a certain amount of baking soda to the diet of finishing pigs can effectively increase appetite and prevent heatstroke. The dosage is 3-4 grams per pig per day, which is mixed with feed for feeding. You can also mix Chinese herbal medicines with heat-clearing and detoxicating in the feed and feed watermelon peel, all of which have a good effect of relieving summer heat and cooling down.

7. Heatstroke pigs should be treated in time (1). After heatstroke in pigs, shortness of breath, salivation, sometimes abdominal breathing, hyperactive heartbeat, irregular rhythm, elevated body temperature, horizontal breathing in dogs, paddling on all fours, swimming, dilated pupils, late systemic contraction, violent vibration and death, with the shortest course of 2-3 hours.

(2) For heatstroke pigs, they should rush to a cool place, spray the whole body with cold water, or repeatedly enema with cold water to cool down, bleed the tip of their ears and take cold feed orally.

(3) Inject 10% sulfamethoxazole sodium and 2- 10 ml or 10% sodium camphor sulfonate and 2- 10 ml. When the illness is exciting, use sedatives, intramuscular injection of chlorpromazine 2-4 ml, or oral administration of barbital 0. 1-0.5 g, and severe dehydration can use saline enema, intravenous or intraperitoneal injection of 250-500 ml glucose saline.
