In the early winter, the outdoor temperature is generally below 10°C. In addition to the depletion of pasture, the nutrients obtained by the sheep from the pasture cannot meet the needs and cause the phenomenon of dropping. Tests have shown that as soon as possible to take a warm shed, can maintain a medium sensation until New Year's Day and the Spring Festival.
The best sheds for sheep should be built on the slope of the corridor. It should be high and low, with a slope of about 30 degrees. The front elevation is 2.4 meters high, the back wall is 1.7 meters high, the corridor is 1.2 meters wide and the front wall is 1.4 meters high. Take the plastic heating shed to be a movable type. When it is fine at noon, open the shed frame and change the air circulation. To clear the manure and urine in time. If it is a fixed plastic greenhouse, it should leave enough ventilation openings, and clean the excreta once every 3 to 6 days to prevent the breeding house from causing excessive respiratory and joint diseases.
Sheep cages plastic greenhouses should pay attention to:
First, insulation. Should choose to build a shed with sunny wind and sunny flat terrain, choose a good insulation polyvinyl chloride film or polyethylene film, etc., use double cover, air separation between the interlayer to prevent convection. Seal the edges and crevices and hang the curtains on the doorway. Maintaining a proper rearing density and fully utilizing the body heat generated by the sheep's activities can significantly increase the temperature in the shed and in the house.
Second, moisture. Because of the good sealing of the plastic greenhouse, the moisture generated by the sheep's excrement or drinking water evaporates, which results in a relatively high humidity in the greenhouse. Failure to pay attention to it will lead to disease. Therefore, when the temperature is high at noon every day, it is necessary to conduct ventilation, timely removal of leftovers, waste water and excrement. Laying of grass or grass ash can play a damp-proof role.
Third, ventilation. After entering the shed, I feel that there is no abnormal odor, pungency, tears, etc. that are too thick. In general, complete ventilation should be performed when the sheep is out of stock or outdoors.
Fourth, wind and snow. The construction should be strong and durable. To prevent the heavy snow from melting and squeezing the greenhouses, the general greenhouses should be 50 to 60 degrees, and the snow should be removed promptly.
