The present invention provides different body temperature and body temperature control required by sows (mothers pigs) and young lactating pigs (young piglets) in piglets, pigs, pigs and pigs, including stole pigs, which are composed of mussel pigs. The aim is to provide a ventilation system for one delivery company so as to supply the amount of inlet air for each to provide the optimal growth environment for each.

In recent years, the economic standard has increased the consumption of meat, the development of the livestock industry, the mass production and the mass supply, and the productivity and the quality of the mass supply. Livestock industry.

The development of the livestock industry is an automatic facility for mass breeders and breeders to improve productivity and quality in livestock farms.

Automated houses are managed by cooling, heating, ventilation, and feeding based on more systematically researched data on pigs, temperature, ventilation, and heat loss.

However, the cooling, heating, and ventilation systems of automatic pens have many difficult problems because they apply numerical data uniformly to each pens, although the conditions such as pens, tonnage, and season are significant.

Therefore, the house system has the trouble of manual management by the manager, and especially in the ventilation system, when the temperature difference between the four seasons and the day and night which are severe in Korea, and the temperature difference between day and night are large, it becomes more difficult to manage.

For example, in the summertime, the zookeepers are opened to the maximum to obtain the cooling effect through natural ventilation, and in winter seasons, the airtight is closed. The environmental problem is caused by the increase of carbon dioxide and odors and toxic gases generated from the excretion, which causes severe fatal damage to the pups along with the lung disease that makes the management of the house difficult and causes infectious diseases. Will be done.

In the Republic of Korea Patent No. 0156293 to improve the problems described above, the outside air flows into one side of the pig house as a ventilation device of the house to form a waiting room, and through the pre-heating of the air introduced into the tube passing through the house in all directions. Ventilation system for supplying the preheated air to the barn and installing a ventilation fan to intake and discharge the air through the bottom of the pig house, and the applicant's prior registered utility model registration No. 0333829, each passage connected by a plurality of flaps The formed air supply duct was provided, and fresh air introduced into the air supply hole drilled in the air supply duct was supplied into the pig house in accordance with conditions such as temperature and season.

In addition, by controlling the opening and closing of the flap for controlling the air supply amount and temperature to adjust the temperature according to the air supply amount and the air supply amount so as to maintain the optimum conditions by always maintaining the proper temperature and fresh air in the pig house.

This prior art is extremely effective control when breeding pigs or piglets and uniformly sized pigs in pigs, while different temperatures are required when sows and young piglets are raised in labor and pregnancy stalls. By doing so, there is a disadvantage in that it is impossible to maintain the required temperature, respectively.

Childbirth is when the mother pigs give birth and fertilize young piglets after pregnancy, breed them to a certain size, move them to other breeding pigs, and the mother pigs reinforce physical strength and rest for the next birth.

However, sows should maintain the temperature of about 25 ℃ according to the increased body temperature due to bloated physique and lack of exercise after delivery, so that the production of steamed rice is increased with maintaining health.

However, if the temperature exceeds 25 ℃, the patient loses strength and suffers from panting to maintain body temperature, and under stress, the production of salted fish is significantly reduced and the feed is not consumed. This results in damage leading to decay.

In order to prevent such damage, air conditioners may be installed in the pig house, but in such forced air conditioners, gas generated in the pig house. It is difficult to exhaust dust, odors, etc., and if the door is always opened to exhaust the polluted air in the room, the cooling effect is lowered and the power consumption and cost consumption due to the air conditioner operation are increased.

In addition, it is known that the optimum temperature for the maintenance of body temperature is 25 ° C, while the young piglets are about 28-35 ° C.

Therefore, the delivery company will have to provide the body temperature by supplying the appropriate fresh air to the mother and piglets respectively.

However, the conventional delivery ventilation system does not constitute a separate ventilation system as described above.

The present invention has been made in view of the above-mentioned problems. Especially, when sows and young lactating pigs are raised together in labor, sows and young lactating pigs differ in body temperature and require different amounts of external air supply according to body temperature control. have.

Based on this, the present invention aims at constituting local supply means so as to maintain indoor air suitable for young lactating pigs living on the bottom of the laboring flock and to reduce the body temperature by intensively supplying intake air to the sows.

The present invention constitutes an exhaust fan for exhausting contaminated air in the delivery company on one wall of the delivery company, and allows the outside air to be inhaled by the negative pressure generated by the exhaust gas to be controlled by the flap, and the intake air is controlled by an elongated intake duct. Sow and young poultry pigs in the pig house as a local supply means to reduce the body temperature of the sows by controlling the room temperature of the delivery company and controlling the intake air from the intake duct to be directly injected into the sows by the air guide plate. This is to keep the body temperature suitable for each other.
