1. Carefully choose to keep excellent boars. Select male boars with standard body weight, no limb disease, symmetrical testis, obvious male characteristics, rapid sexual reflexes, good constitution and health status for breeding purposes; and select semen for large amounts of semen according to boar semen test results. High density and strong boar. After ageing boars have been phased out, they will be replaced or replaced by excellent young boars to improve the quality of summer semen.
2, adjust the diet formula. Specific practice: appropriate to reduce the carbohydrate content of feed, add 2-5% of the fat in the feed, such as feeding two eggs per head per day or feeding 0.25 kg of small fish (cooked soup to feed). Adding 200-500 mg/kg vitamin C and 200 mg/kg vitamin E to the feed can reduce cortisol levels in pigs during heat stress and improve immunity. The Chinese herbal medicines such as hawthorn, atractylodes rhizome, dried tangerine peel, betel nut, astragalus membranaceus, daqu, etc., which are used for heat-removing and heat-releasing, are formulated as feed additives, which can relieve the heat stress of breeding pigs.
Second, take effective cooling measures
1. Conventional methods: The type of boars should be high and spacious, and thicken the roof insulation layer; use lime to paint the outer layer of the walls, and plant tall trees and gourd, pumpkin and other vines around the pig farms and pig houses for shade. Install exhaust fans, ventilation fans and other equipment. Strengthen ventilation to promote body heat dissipation, with a hose or sprayer to the pig body and roof spray water cooling or artificial sprinkler cooling. Cooling with a wet curtain, when the wet curtain thickness is 12 cm, and the curtain wind speed is 1-1.2 m/s, the wet curtain cooling efficiency is 81-87%, which can reduce the sheer temperature by 5-8°C. The higher the temperature, the lower the temperature. The better the effect. In addition, providing sufficient clean cold water or well water for breeding pigs, artificially washing the boar testicles is also an effective means to reduce the impact of high temperature on breeding of boars.
2, the application of water-cooled air conditioning, construction of a constant temperature pig house. The pig house was closed and renovated according to the number of breeding pigs before entering the summer. The interior of the pig house was insulated with ceiling ceilings. All aluminum doors and windows above the front and rear doors and walls were equipped with aluminum alloy windows and screens were provided for regular ventilation. Two 1000W water-cooled air conditioners are installed on the east and west sides of the house, and two exhaust fans are provided. When designing and producing a kind of boar, each cage is 2.2 meters long and 1 meter wide. The trough is equipped with a feeding trough and an automatic drinking fountain on the south side. Cage door. A prefabricated slab of slatted cement is installed in the cage. Under the slab, a 25-30 cm hollow is drilled from the south to the north. The urine effluent flows into the deep sewers to the north of the cage and is discharged to the outside digester. A sperm collection room is located on the east side of the house and is separated from the laboratory by aluminum alloy glazing. When the outside temperature exceeds 30°C, the water-cooled air conditioner is started and the indoor temperature can be maintained at about 25°C.
3, adjust feeding, exercise time. It is advisable to feed the pigs in summer, but it is possible to have dinner at around 6 o'clock in the morning and it is late at 19 o'clock in the evening. The wet mix can be moister and fed with green feed to improve palatability. Each day, 0.5-1 hour drive was performed after early feeding and before late feeding.
4. Do a good job of prevention and control of the disease. In summer, high temperature and high humidity make pathogenic microorganisms prone to breeding, and the heat stress reaction will induce some hyperthermia diseases to affect semen quality. Therefore, a kind of boar should pay more attention to environmental sanitation during the summer hot season. Remove leftovers in time to prevent feed moldy and spoilage; brush sinks and drinking fountains on a regular basis; remove manure in a timely manner to keep the room dry and ventilated; regularly spray insecticides on pig house walls, playgrounds, and sperm collection rooms to eliminate mosquitoes and flies; Disinfectant drugs, alternating spray disinfection; tools and work clothes should also be cleaned and disinfected on time to avoid cross-infection; pig farms should strictly carry out swine fever, No. 5 disease, pseudorabies, parvovirus, Japanese encephalitis, and brucellosis Other immunizations and deworming work in spring and autumn. At the same time, attention should be paid to the effects of certain drugs such as sulfa drugs, trichlorfon, and certain vaccines on the quality of semen in the prevention of boars and treatment of boars. Chinese herbal medicine should be used to reduce the impact.
