Boars have a profound influence on the swine breeding program, not only do they provide a source of genetic improvement, but they also affect farrowing rate and litter size, the pens for boar is of great importantance, a scientific boar pen will enhance the whole pig farm running efficiency.
Boar pen: The length of the adult boar is up to 2m. In order to facilitate the boar to turn around, the width of the general boar pen is not less than 2.4m, the length is not less than 3m, and the height of the fence is not less than 1.2m. There is a sports field outside the house to increase the amount of exercise and prolong the life of the boar.
Breeding pens: It is necessary to set up a separate breeding pens in a 10,000-head pig farm. Since the breeding boars must be close to the hindquarters of the sows before climbing on the sows for breeding, the length of the pig house should be at least the length of the breeding boars and the sows. Total length of nose to tail. Also, since the boar has been chasing the sow in the pig house before breeding, the boar needs space to walk forward in the pig house, so as not to use the hind limbs as a fulcrum or turn with an arched back when turning around.
According to the above principles, the length of the breeding column should not be less than 3.5-4.0m, and the width should not be less than 3.0m. Because it is very difficult for boars to approach young sows in the corner of the pig house, the breeding house is designed in an octagonal shape, the floor of the pig house is designed to be non-slip, and no obstacles such as feeding troughs and drinkers are installed in the house to affect the balance of the pigs.
Mus Agro factory have an annual production capability of 300,000 tons pig crates, all the pig crates welding production is by intelligent automatic robot welding line, which can keep a uniform welding quality. In the overall hot-dip galvanizing production process, all pig crates are well cleaned by the strong acid before galvanizing, after galvanizing the zinc layer thickness is controlled to 85um above,which can guarantee the long years service life, so as to make sure all pig crates quality is well guaranteed.
As one professional pig crates supplier, Mus Agro has sufficient stocks pig crates for sale in the factory warehouse, which can support the large scale pig farming equipment purchase and wholesale pig crate pruchase requirement in the market, outstanding quality and reliable serive is the prior target of Mus Agro team.
The boar pen adopts the structure of partitioned brick wall and metal fence, the fence is made of hot-dip galvanized pipe, the outer frame is made of steel pipe, the vertical and horizontal bars are made of steel pipe, and each boar pen is equipped with a cast iron trough and a pure copper duckbill type. Automatic water dispenser.
1. Breeding boar pen
Traditional boar houses mostly use a single row with a sports field, which can ensure sufficient movement to prevent the boar from being over-fat, improve the quality of semen, and prolong the service life of the boar. There are corridors in the house. The area of the boar pen is generally 7~9m2, the length is 3~3,5m, the width is 2.3~2.6m, and the height of the fence is 1.2~1.4m. The fence structure can be concrete, metal, or both. Combined, that is, the lower 1/3 part of the fence uses a concrete structure, and the upper 2/3 part of the fence uses a metal barrier structure. In contrast, concrete structures are not as conducive to longitudinal ventilation as metal fences. At present, due to the standardized application of artificial insemination, many large-scale pig breeding farms have their own boar studs, and use the limit bar model to build boar sheds, which greatly improves the efficiency of pig sheds and facilitates the control of the small environment of pig sheds. better effect.
2. Feeding equipment
Manual feeding equipment mainly includes hopper trucks, feeding measuring tools, etc. The boar trough is of cast iron or concrete construction. The size and height of the feeding trough are designed and installed according to the needs of the pig body for feeding. There are also some boar houses without feeding troughs, and the feed is directly placed in a corner of the single-breed boar house. The premise of not setting up a feeding trough is that the boars must be trained in the three-point and one-line living habit of “feeding, excretion, and rest”, so as to achieve fixed-point excretion and not pollute the feed. In some new large-scale pig farms, automatic feeding equipment is used to reduce labor and achieve feed quantity control. The automatic feeding system is composed of computer control system, material storage tower, power machinery, conveying pipeline, trough, etc. It can directly feed dry powder.
3. Drinking water equipment
Breeding boar houses usually use automatic drinking water systems, mostly direct drinking water supply equipment, mainly using duckbill and nipple automatic drinking fountains. In the single-breed boar pen, the drinking fountain is generally placed opposite the feeding trough to prevent the water from splashing the feed when the pigs drink water. In the limit barn for boars, drinkers are generally installed on the left and right sides of the front door of the limit frame. The height of the drinking fountain is 40-60 cm. The laying of exposed pipes outside the breeding barn should avoid exposure to sunlight and freezing.
4. Heatstroke prevention and heat preservation facilities
For boars, heatstroke prevention and cooling are very important, especially for pig farms with balanced breeding production all year round. Because the temperature is too high, the quality of semen will drop sharply, and short-term high temperature can lead to long-term infertility, which will seriously affect the reproductive rate of pig farms.
The optimum temperature for breeding boars is 18-20°C. In winter, the pig house should be protected from cold and heat to reduce the consumption of feed and the occurrence of diseases. When the temperature is high in summer, it is necessary to prevent and cool down. The measures to prevent and cool down include air conditioning, ventilation, spraying water, bathing, cooling with wet curtains, and shading.
5. Ventilation and ventilation facilities and equipment
The purpose of ventilation is: when the temperature is high, the pigs feel comfortable through air flow; when the pig house is closed, the fresh air outside the house is introduced, the dirty air in the house is removed, and the air quality in the house is improved. The former can be called ventilation, the latter can be called ventilation.
In order to eliminate the foul and harmful gases in the breeding boar house and reduce the high temperature in summer, ventilation and ventilation equipment must be installed. The ventilation rate needs to be based on the area of the house, the number of pigs raised, and the carbon dioxide or water vapor content in the air in the house. Breeding boar houses generally use mechanical forced ventilation, mostly using negative pressure longitudinal ventilation mode or combined with wet curtain cooling system to achieve cooling effect while ventilating.
