In summer, the temperature is high. In addition to improving the ambient temperature of the pig house, it is also necessary to meet the changes in feeding and management in order to stabilize pig growth and production. Reduce feeding density Reduce the ratio of 1/4 to 1/3, can avoid crowding, improve air quality, reduce heat stress, especially pregnant sows, if the density is too large, will cause abortion due to hot irritability fight, it is best to keep a single bar. Sale, castration, and vaccine injections should be conducted in the morning and evening. During the long-distance transportation of pigs, drinking water and spray water cooling should be provided. Controlling breeding and laying time Properly avoid the hottest breeding during July and August and the birth of a litter, and reasonably arrange production; at the same time, breeding and harvesting will be conducted in the morning and evening when it is cool. Choose sows to give birth on a cool morning in the morning about 3 days before delivery. Sows often have a long delivery time at high temperatures, causing the fetus to stay in the birth canal for too long and suffocate. Chlorprostinol 0.2 mg/head can be injected in the morning two days before the expected date of delivery. After about 24 to 28 hours, the blood can be delivered, 3 to 5 heads can be delivered, and 3 to 5 ml of oxytocin can be injected. This can induce sows to give birth in the early morning, shorten labor and reduce stillbirth. Keeping the sanitation At least 2 to 3 times a day to clean up the feces, 3 to 4 times a month disinfection, and do a good job of eliminating mosquitoes and flies. Controlling the amount of dietary feed daily Increase the nutritional intake of heavy and lactating sows. Under high temperature, nursing sows should maintain a high level of nutrition, can add 2% to 5% fat powder, 2% of high quality fish meal and 0.1% to 0.2% lysine, sow daily feed intake 4 weeks before delivery Should reach 2.5 to 3.2 kilograms, flourishing period should reach 6 kilograms or more. Select high-quality fresh ingredients and add attractants to increase feed intake and maintain high growth rate of commercial pigs. Change the feeding method 1. Change the material type, use wet mix, the ratio of water to feed is 1:1, it can increase the feed intake by about 10%, but it should be fed now to prevent rancid spoilage; at the same time, feed more green feed, especially sows. 2. Increase the number of feedings and add night feeding, especially sows at the peak of lactation. 3. Adjust the feeding time, feed in the early morning and evening cool, try to avoid feeding at noon, do early morning feed, feed more at night, feed at night. However, the adjustment of feeding time should be gradual, gradually adjusted as the temperature changes, and cannot be suddenly changed. Inhibit rising body temperature in pigs 1. Increase the number of drinking fountains; regularly check the drinker (with or without clogging); drinkers must have sufficient pressure to ensure flow, sows are 1.5 liters per minute and finishing pigs are 1 litre per minute. 2. Add 0.1% to 0.2% artificial salt or 0.5% baking soda to drinking water to adjust the electrolyte balance of the sow and reduce the occurrence of heat stress. 3. Use cool deep well water. The water pipes should not be exposed to the sun, which is beneficial to the cooling of pigs and stimulate the intake of food. While nursing sows cool down, piglets must be protected from high humidity and blown-out fans. 4. Make sure that the drinking water on the playground is uninterrupted and place the water cooler in a cool place to avoid direct sunlight heating up.
