When winter comes, the temperature is lowered, and the cold gas invades the pig house, which is easy to cause diseases such as colds and pneumonia in pigs. It is especially prone to cause diarrhea in piglets and increase mortality. Therefore, winter pig houses should be protected against wind and heat. For large-scale pig farms, most of them have winter insulation measures during design and construction. Here, some suggestions for winter insulation measures are proposed for some small and medium-sized pig farms in the south, and most of them are easy to use and low in cost. First of all, from the easy-to-see places, the doors and windows of the pig house should be completely covered, and the curtains can be made by splicing with linen bags, or covered with plastic cloth, but it should be noted that when using plastic sheets, beading should be done at the bottom to prevent being blown away by the wind. If the window is damaged, it should be completely sealed. Be careful not to miss the vent or the exhaust fan used in summer. Simple curtain The windows are all sealed. Be careful not to miss the exhaust fan vents. Some pig houses have outdoor parts, should be set up with plastic sheds, closed, leaving only the manure. The utility model has the advantages of cost saving, remarkable effect and convenient production. Most of the free-range households can generally follow the mode of the circle, according to local conditions, because it is simple. The plastic shed is light-transparent and warm, and the wind and rain are released. Generally, the room temperature can be increased by about 5 °C, which is beneficial to the growth and weight gain of the pig. However, it should be noted that snow should be removed in time to avoid crushing the plastic shed. In addition, turning roller blinds is also a good choice, so you don't have to take a plastic shed every year. Unclosed pig house Closed pig house Adding roller blinds is also a good choice [NextPage] Most of the pig houses in the south are tile houses, and the roof space is large. The space is not conducive to heat preservation. It can be placed on the roof to reduce the space. The height of the ceiling is about 2 meters from the ground. The sawdust or rice husk is placed on the shed, which can also effectively improve the temperature. Increased ceiling in the pig house For newborn piglets, cold weather is a great stress. If the temperature difference between day and night is more than 5 degrees, diarrhea may occur. Therefore, the insulation of the delivery room is particularly important. However, the delivery room should also pay attention to ventilation to prevent respiratory diseases. For the delivery room, the following measures can be taken: 1. When the temperature is high at noon, the front and rear windows can be opened to convect the air; 2. The incubator should be covered with sacks in addition to the heat preservation lamp, and the upper part of the incubator should be covered; If the sack is wet, it should be replaced in time. The piglet should not be allowed to sleep on the wet sack. 4. Adjust the direction of the water outlet of the drinker and the size of the water flow to avoid the water flowing into the barn when drinking water. Covering the piglet incubator The nursery bar can also be surrounded by plastic sheets and added with heat lamps. Increasing density feeding is also an effective measure to cope with low temperature in winter. In addition to the delivery room, pigs at other stages can increase the stocking density appropriately. In general, the number of pigs in the house can be increased by about 1/3 compared with usual. It is better when the group is in the dark when it is in the dark. It can be sprayed with some low-concentration stimulating syrup, such as wine, vinegar, and lysine. Pig fights. At the same time, it should be noted that the pig house is kept dry, the humidity is higher, the colder the feeling, the excessive humidity is likely to cause respiratory diseases, infectious diseases and parasitic diseases in pigs. To allow pigs to urinate and urinate, clean the pig pens every day, keep the pigs in a clean and dry place, provide a comfortable living environment, and promote the growth and health of winter finishing pigs. Bearings play a vital role in the machinery industry. Here are a few of the main roles of bearings in the machinery industry: Machine Tapered Bearings,Tapered Roller Bearings,High Precision Hardness Bearing,Low Noise Bearing Hebei Fangqiang bearing manufacturing Co., LTD , https://www.fangqiangbearing.com
1. Support and positioning: Bearings are used to support rotating shafts and wheels so that they can rotate smoothly and ensure that their positions are accurate. Bearings enable machinery to operate efficiently by reducing friction and resistance.
2. Transmit force: Bearings are able to transmit force in mechanical equipment so that it can work properly. For example, crankshaft bearings in automobile engines transmit the power generated by the engine to enable the vehicle to move.
3. Reduced friction and wear: Bearings reduce friction and wear in mechanical equipment by providing lubrication and reducing direct contact between metal surfaces. This not only extends the service life of the mechanical equipment, but also reduces the frequency of maintenance and repairs.
4. Protection against vibration and noise: Bearings reduce vibration and noise in mechanical equipment. By balancing and stabilizing rotating parts, they reduce vibration and noise during the operation of mechanical equipment.
In conclusion, bearings play a vital role in the machinery industry, supporting and positioning rotating components, transmitting force, reducing friction and wear, and preventing vibration and noise. Without bearings, machinery and equipment would not function properly.
