| it is believed that the biggest fear of many pig farmers is that the pig is barren, especially in summer. because of the high summer temperature, in domestic animals, the temperature of pigs is poor, and the ability of heat and heat is far less than that of cattle and sheep. the temperature of a pig's rectal temperature starts to rise, and if it persists, the pigs will not tolerate it. it is easy to get a "sterility" disease in pigs during this time period. that would be a big loss for pig farmers this summer. therefore, people have been looking for a solution, on a hot summer farmers are worried, for safety through the "summer infertility" period, the following hopes to help the farmers: 1. reduce feeding density. 2. strengthen the management of breeding, and elaborate the preparation of summer food. 3. reduce the crude fiber content in daily grain, especially to reduce bran and rice bran ratio. 4. pig food must ensure protein, energy, minerals, vitamins and other nutrients, especially the content of lysine increase (from 0.5% to 0.9%). 5. increase the content of vitamin a, e, c, folate and biotin in particular, and ensure the full supply of zn, se, mg, k and na in the daily grain. because these nutrients balance the humoral, the normal development of follicles plays an important role. 6. add oil and grease properly. this can not only meet the energy needs of the sow, reduce the loss of weight, but also improve the survival rate of piglets. 7. improve the building of the pigsty. adopt open or semi-open, and pay attention to the orientation of the pigsty. the roof of the pig house is made of heat-insulating materials. the conditions can be provided for the shallow water pool in the playground for the pigs to be rolled out in the pool to cool down. 8. strengthen the ventilation of the piglet. open doors and windows, install ceiling fans, fan and air convection. 9. make the pig farm greening. by shading, reducing radiation, trapping rain and transpiration, the plants can reduce the heat of the pig farm by 50-90%. to make the whole pig farm a comfortable and cool climate under the cover of green trees. not only do you need to plant more trees around the stadium, let vines climb up the roof and walls to give full play to the shade insulation of green plants. |
