There should be some pig-raising equipment for heating and ventilation in the pig house to ensure the normal healthy growth and production of herds. Pay attention to the environmental sanitation in the piggery, and disinfect the piglet troughs, automatic feed troughs, sow troughs and other equipment in time.
Pig house heating heating and partial heating two. Central heating uses a centralized heating device to generate heat medium. The heat medium is then sent to the radiator in the pig house through pipes, and the air in the pig house is heated to maintain a suitable temperature in the pig house. Local heating has hot water heating floor, hot plate, infrared light and so on.
Ventilators suitable for use in pig farms are mostly large diameter, low speed, low power fans. This fan has a large amount of ventilation, low noise, low power consumption, and durability.
Ventilation and ventilation should pay attention to the following issues: (1) Avoid fan ventilation and short circuit, must not be set on the wall of the fan, the bottom is through the door, so that the air flow to form a short circuit; (2) If unilateral exhaust, should be two The ventilation outlets on the side adjacent pig houses are located on the opposite side to prevent one of the discharged air from being immediately inhaled by another pig house; (3) Try to make the airflow pass through most of the space in the pig house, especially the ditch On the other hand, do not create dead ends to achieve ventilation.
Although ventilation is an effective means of cooling, it can only reduce the temperature of Scheuwen to a temperature close to the outside ambient temperature. When the ambient temperature outside the house is greater than the maximum temperature of the pig production (27~30°C), the ventilation is At the same time, cooling measures should also be taken to ensure that the temperature is controlled within a suitable range.
The cooling system commonly used in pig farms is wet curtain-fan cooling system, spray cooling system, spray cooling system and dripping cooling system. Because the latter three kinds of cooling systems have high humidity, they are not suitable for delivery rooms and toilets. The wet curtain-fan cooling system is currently the most mature evaporative cooling system. Its evaporative cooling efficiency can reach 75-90%, and it has been widely used throughout the world.
Field cleaning and disinfection equipment commonly used in pig farms includes high-pressure cleaners, flame disinfection, and backpack sprayers. Flame sterilizer and drug disinfection with the best results, the first use of drugs after disinfection, and then sterilize with a flame sterilizer, sterilization up to 95%.
In modern pig farms, in order to maintain the cleanliness of the fence and reduce artificial cleaning, the floor of leakage floor is generally laid on the manure urine ditch. After the pig urinates on the dung floor, the urine flows into the ditch along with the gap, and the manure falls to the floor of the dung floor. On the other hand, after being stepped on, it automatically falls into the dung ditch below, thus avoiding the contact between pigs and feces, which will help prevent and reduce the occurrence of epidemics.
According to its range of laying in pigsheds, slatted floors are divided into two types, namely full-leakage and partial-leakage, and all-fed barn and nursery stalls raised on high beds should adopt full-leakage floor and pigs raised on the ground. Partial floor drains (1/3 to 1/2 floor drains) are generally used. The row pool area of the pig is the floor of the dung, while the area of the feed and rest area is the physical ground.
The key technical parameters of the floor draining soil are the width of the leaking feces, the width of the leaking seam is too small, the leakage rate is low, and the leakage of the feces is poor; the width is too large, causing the trotters to slide into the leak gap and cause serious hoof leg injuries. Dung floor has a variety of shapes, generally made into blocks, strips or nets. The materials used are cement, metal, plastic, etc.
