Pigs with reasonable feed are not anorexic
When the temperature rises above 35 ℃, the feed utilization rate is low and the weight gain is slow. Therefore, different feeding methods should be given according to different types of pigs and different physiological stages of pigs in high temperature season.
Boar: feed twice a day, plus green fodder or thinner at noon. Mating and exercise are carried out in the morning and evening, do not immediately hit Wang or spray cold water after mating. Spray water on the pig body and ground once from 1 pm to 3 pm every day, and the light is reduced to 8-10 hours. if the number of mating is less, the amount of concentrate feeding should be reduced to prevent overweight and poor libido.
Pregnant sows: pregnant sows should be based on green coarse feed, properly matched with concentrate, reduce feeding density, 2-3 per captive. In the later stage of pregnancy and lactation, one pig circle, mainly concentrate properly with green feed, coarse feed can not be fed; feed 3 times a day, add thinner in the middle, spray water once. Add 1-1.5% baking soda and 0.3% salt to the ingredients. In addition, breeding in high temperature season should be avoided.
Parturient sows: the summer delivery room should choose a litter with good ventilation and sunshade facilities. Sows 2-3 days before parturition reduce concentrate, feed more green feed, concentrate in the proportion of wheat bran should be increased, in order to clear intestines and prevent constipation for the purpose of preventing dystocia. Feed bran and warm salt water once after giving birth.
Commercial pigs: difficult to raise in high temperature season, often inverted trough, do not eat, affecting growth. Generally, fat pigs are sold before the hot season arrives. If not, the feeding density should be reduced. Spray water to cool down, feed in the morning and evening, add green material or dilute material at noon, add 1.5% baking soda and 0.3% salt.
Suckling piglets and piglets: like to lie on the wet ground, pay attention to the weather changes to prevent cold diarrhea or diarrhea. Keep the dough dry for clean drinking water and often disinfect. Prevention can be fed with 120 milligrams of oxytetracycline per kilogram for several days, and 200 milligrams of oxytetracycline per kilogram during treatment.
Prevention and treatment of heatstroke. First of all, move the affected pigs to a cool and ventilated place and spray the whole body with cold water after drying, cut the tail, cut the ears and bleed, and carry out drug treatment at the same time.

Pig driving skills
1. Design a road for pigs: that is, when you enter the pigsty or get on the bus when selling pigs, there is a man-made road, and the walls of this road had better be fixed and solid walls. If not, you can use temporary walls, such as iron railings, long stripes of colored cloth (you can also sew long stripes of cloth with feed bags), or other opaque boards, so that pigs can see that it is right only to move forward. in this way, the general pig will follow the path designed for it; this method is more practical for sows. 2. Temporary wall
