What is the high temperature and breeding inbreeding?
I believe that many pig farmers are most afraid of breeding pigs are infertile, especially in summer. Because of the high temperature in summer, in pigs, the body's thermoregulatory capacity is relatively poor, and the heat-tolerance capacity is far lower than that of cattle and sheep. As the temperature rises, the rectal temperature of the pig begins to rise. If the temperature continues to increase, the pig will not tolerate it. Pigs are often susceptible to "infertility" during this time period. In this summer, the pig farmers will be greatly damaged. Therefore, people are always looking for a solution. Every hot summer season, pig farmers are in a hurry. To survive the “infertility period in summerâ€, the following points are hopeful to help pig farmers: 1, reduce the breeding density. 2, strengthen the feeding and management, carefully prepared summer food. 3, reduce the dietary crude fiber content, in particular, to reduce bran, rice bran ratio. 4, pig food must ensure that the protein, energy, minerals, vitamins and other nutrients, in particular, should increase the lysine content (from 0.5% to 0.9%). 5, to increase the vitamin A, E, C, folic acid and biotin content, to ensure adequate supply of Zn, Se, Mg, K, Na in the diet. Because these nutrients balance the body fluid, it plays a special important role in the normal development of the follicle. 6, appropriate to add grease. This not only satisfies the energy needs of the sow and reduces the loss of weight, but also improves the survival rate of the piglet. 7. Improve the construction of the pig house to ensure it is cool in winter and cool in summer. Adopt open or semi-open style, pay attention to the direction of the pig house, use the heat insulation material on the roof of the pig house, and conditionally set up a shallow pool on the sports ground for the pig to cool down in the pool. 8, to strengthen ventilation in pigs. Houses open doors and windows, install ceiling fans, exhaust fans, and enhance air convection. 9, do a good job pig farm greening. Trees can reduce radiant heat by 50-90% by shading, reducing radiation, and trapping rain and transpiration. Through the greenery, the whole farm is under the shade of green trees to form a comfortable and cool microclimate. Plant trees around the stadium to allow the vines to climb onto the roof and walls to give full play to the shading and heat insulation of green plants.
