3 . The internal equipment of the shed
(1) In addition to the barn pen house, the incense sire bar must be provided with bars in the general barn. The materials required for the barn can be based on the local conditions. reduce manufacturing cost. 5. The fence between male pigs and fat pigs should be constructed in the form of short walls. Avoid mutual interference with each other. For other fragile pigs, the fences used in the flock should be fixed fences, and the fences can be fenced in order to adjust the area of ​​the bar. According to production needs, they can be raised in a single lap and reared in groups. Large-scale farms, for the sake of easy management, the columns of the pigs are generally finer, including public fragrant pigs, empty-breeding fragrant pigs, pregnant mother fowls, farrowing mother fowls, young fragrant pig nurseries, and growing and finishing. Xiangni bar and so on.
1 male pigs and empty scented pigs. The arrangement of such pigs should be considered to be beneficial to the full use of pig breeding and fragrant pig houses. Generally it is a single-row fragrant pig house, which can be divided into two columns before and after, and the middle is a breeding area (Figure 9-8). Its characteristic is that it can induce estrus to each other and facilitate the discovery and inspection of estrus pigs.
2 pregnant mother incense pigs. There are many forms of pregnant hens and pigs, and the farming methods are also varied. There are 1 pig (2-5 heads) breeding for 1 column. There is also 1 bar in a single pig. The separate pregnant mother pigs are bred in one tier to avoid biting, colliding, and competing for food, reducing the miscarriage of pregnant mother pigs and increasing the survival rate. Pork bar is made of steel pipe or wood. The disadvantage is that it consumes more materials, the construction investment is large, the activity of female pigs is restricted, the exercise is small, legs and hoofs are easy to occur, and the useful life of female hogs is also reduced.
3 points 娩 mother squid bar. The farrowing bar is divided into two parts, a parturition shelf and a delivery bed. The farrowing shelf is installed on the bed (Fig. 9-9). The litter frame has a length of 1 meter, a width of 0.3 meters, and a height of 0.5 meters. The bed is 1m long, 0.8m wide and 0.2m above the ground. The mesh at the bottom of the obstetric bed can be meshed with 0.5-cm2 steel wire. The middle part of the farrowing bar is the restricted area of ​​the mother porcine pig, and the side of the barn is the activity area of ​​the Xiang pig. The front end of the limit zone is provided with a mother fragrant pig trough and a drinking fountain, and the tail end should be equipped with a cross bar to prevent the mother fragile pig from retreating. At the same time, we must also provide insulation devices in the activity area of ​​the Xiangxiang pigs, such as incubators, infrared lamps, and electric floor, and feed troughs and drinking fountains.
4 Zixiang pig nursery. The newly weaned Zixiang pigs are not yet fully functional, have poor adaptability, and are in a vigorous stage of growth and development. Therefore, there is also a need for a period of conservation to provide them with a clean and warm environment. Nursery bars are generally made of reinforced welded mesh beds (Figure 9-10). Nursery columns are generally 1 meter long and 0.8 meters wide, with an area of ​​about 0.8 square meters, and a mesh net with 0.5 square centimeters is generally appropriate. This nursery can keep about 10 weaned pigs. Before you install the trough and drinker.
5 Growing and fattening pigs. The growing and fattening pigs are constructed in a variety of forms, including aluminum alloy partitions with a relatively large investment, cement floors and metal leaky floor joints, and metal fences, cement floors, and water contaminants that are convenient for maintenance and disinfection. The combination of slatted floors; there are also cement septa with less investment, but inconvenient maintenance, and the combination of cement floor and cement leaks. The differences between the regions, especially the north and the south, are relatively large. The scale of farming is not the same. According to the local conditions, the principle of spending less money, doing more things, and doing good things, and adapting to local conditions, choose the farming mode that suits them.
