In the fall, temperatures in most parts of northern China and northwestern China have dropped suddenly, and outside temperatures are generally below 10°C by the end of autumn and winter. Combined with the depletion of pasture, all the sheep’s nutrients obtained from pastureland can no longer meet physical energy consumption and can only be consumed in vivo. The stockpiling of nutrients causes serious dropouts. Therefore, to prevent sheep from falling out, we must use a plastic greenhouse. Tests have shown that every year at the beginning of October, sheds, more than 80% of the sheep can only be dropped out of the phenomenon can be prevented, so that the public sentiment to the New Year's Day and the Spring Festival listing, its benefits can not take advantage of plastic sheds only sheep more than 50 yuan. 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. Designing the shed according to the size of the flock should not be too high to prevent body heat consumption. 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. At present, China's sheep-raising households are still relatively extensive. The vast majority of sheep-raising households use the form of large-scale sheds. It is neither convenient nor economical to adopt plastic greenhouses, and can be slightly modified. The method is to build a brick wall in front of the shed. The distance between the height and the distance from the shed should be determined according to the height of the original shed, but it should be determined with the maximum amount of light collected. Closed two-slope sheep houses should be modified inside and outside. If the top of the roof is more than 3 meters, you can use a plastic greenhouse roof. External plastic greenhouse sheds are wide and narrow to determine the size of the flock. In China's pastoral areas, there are mostly high-cold grasslands for raising sheep, and up to 7 months in winter. Putting plastics in greenhouses can effectively prevent the occurrence of film dropping and lack of spring. Sheep pens plastic greenhouses should pay attention to: 1 insulation. Should choose to leeward sunny, flat and dry place to build a shed, choose a good insulation plastic. At present, PVC film and polyethylene film should be selected. Double-layer covering is used to cover the double-layer plastic film and an air insulation layer is formed between the interlayers to prevent convection from occurring. Seal the edge of the plastic film and repair damaged parts promptly. Establish appropriate stocking densities and fully utilize the body heat generated by the sheep's activity, which can significantly increase the temperature in the shed and in the house. 2 moisture. Because the plastic greenhouse is sealed, the moisture generated by the excrement or drinking water of the sheep does not evaporate when ventilation is not performed, which results in a relatively high humidity in the shed. During feeding, if it is not noticed, it will lead to decreased productivity and disease, so , Open vents or skylights for ventilation at noon high temperatures every day. Reduce water in the shed, remove leftovers, waste water, and excrement. The laying of grass or ash, can be properly absorbed moisture to play a role. 3 ventilation. After entering the shed, we feel that there are no abnormal odors, pungent noses, tears, etc. that are too thick, indicating that there are fewer harmful gases such as ammonia gas and hydrogen sulfide in the sheep shed, and ventilation can be appropriately reduced to facilitate thermal insulation. On the contrary, the ventilation and ventilation time should be prolonged, and the general ventilation should be performed when the sheep is grazing or outside.
Walker
Walking aid, as its name implies, is a walking aid. Its function is to support weight, maintain standing balance, and assist walking, so as to realize compensation and improve walking ability.
As an assistive device, walking aids are indispensable in the rehabilitation training process of age, limb disability and limb injury, so how to choose a suitable walking aid is also a learning.
Walking aids are a large category, which can be divided into walking sticks, walking frames and wheelchairs from simple to complex.
What should we pay attention to when using?
1. Adjust the height of the walker according to the user's own conditions. The general principle is correct posture and comfortable use.
2. Necessary inspection shall not be less to ensure safe use.
â‘ Is there any problem with the deployment and storage of the walker; â‘¡ Check whether each part is loose and whether there is burr on the surface of walking aid; â‘¢ Whether the feet or wheels contact the ground smoothly and whether the wheels are flexible; â‘£ The locating pin is not firm, can it be fixed
3. Installation and removal of accessories under specific conditions
â‘ Provide cushion for rest; â‘¡ Sitting bath board for bathing; â‘¢ Toilet board for auxiliary toilet use; â‘£ Shelves and shopping bags for storing things. Use and carry according to the situation, grasp the measure, and the main purpose is to assist walking.
