Breeding bed winter pig management points
Now that winter is coming and winter temperatures are low, many pig houses must adopt warming and warming measures, such as heating and heating, furnace heating, and hot stove heating. Although these methods have played some insulation effects, air pollution has also appeared. Poor ventilation leads to various diseases in pigs. How can we keep warm?
Fermentation bed farming is the best choice! Fermentation bed produces a lot of heat while decomposing excrement and urine. All over the country, the temperature of the bed surface of the fermentation bed is proved to be at 20 degrees every year, which can significantly increase the indoor temperature in winter, just meeting the need of pigs for temperature, in the northeast of our country and other places. Both prove that winter does not keep warm, and the growth of the pig is very good. Therefore, the use of fermentation bed breeding completely without heating, easy winter. However, we must also pay attention to the following points:
First, the housing structure is particularly in the north, and the surrounding walls must be thick and tight. It is possible to stack crop stalks, and to temporarily build clay soil. It is best to thicken the outer walls when the pig house is built. The use of insulation materials such as foam boards on the roof, thermal insulation in summer and winter heat have very good results, and the demand in the south is slightly worse.
Second, regular maintenance of litter According to the accumulation of excrement, the humidity of the litter to flip, push and uniform treatment, to avoid the emergence of blisters due to the phenomenon of increased humidity, winter fermentation bed technology, fermentation bed experts to remind the thickness of the litter Can slightly increase, the minimum is not less than 50 cm, in order to increase the fermentation intensity can increase the amount of strains, spraying brown sugar water, increase the frequency of turn, etc., so that the fermentation bed deodorization of environmental protection and thermal insulation to play the best.
Third, ventilation can not be ignored Some farmers believe that ventilation and warmth are very contradictory, so close the various vents in the cold climate, I do not know this is very wrong, especially the fermentation bed breeding, winter ventilation can not be less, otherwise it will appear The large ammonia odor, high humidity in the fermentation bed, and poor ventilation caused the aerobic microorganisms in the fermentation bed to die due to lack of oxygen. Eventually, the fermentation bed failed and the pig suffered a cold and other diseases. Therefore, the winter fermentation bed was also ventilated. Specific methods can be used. : Open all vents in good weather during the day and keep the temperature low or leave some vents in the evening. Remember not to close them completely.
IV. Management of Piglets During piglet stage, especially the suckling pigs that are just under high temperature requirements, generally 30-35 degrees, they can be kept warm at 0-7 days old to avoid various symptoms such as diarrhea. Do a good job of disinfection.
Fifth, other management points 1 to increase the temperature of drinking water, conditions can be warm water after cold water for pigs to drink, or pumping deep ground water to feed the pigs. 2 The purpose of increasing the number of feeds is to relatively increase the feed intake to compensate for the weight loss caused by the body fat and intramuscular metabolic heat production caused by the low temperature. Where conditions permit, it is best to take free food. Feeding can be added at night in places where feeding is scheduled. 3 To increase the energy level of feed can be increased by about 10% based on the original feed energy level. The big pigs are low and the pigs are high. Piglets can be supplemented with high-energy feeds for fats and oils. Big pigs can increase the amount of common energy feeds such as corn in batches. 4 Increase the lighting area of ​​the pig house The open pig house must have a large open area in order to prepare for the winter covered plastic film for easy lighting. Closed pig houses are to be reserved in the south wall and the roof to prepare for the installation of glass in winter. 5 Increase the density such as the fermentation bed can be properly cultivated density of 10% in the winter.
Greenhouse Vertical Hydroponics allows you to grow fresh vegetables and fruits at much higher crop yields and relatively lower costs. Thus, not only is it a profitable undertaking, but one which has proven of great benefit to humanity. With Greenhouse Hydroponics, plants can be raised out of season resulting in better control and higher yields of crops.
