Construction method of Piggery in Rural areas
Big shed type: it is mainly composed of greenhouse and plastic, which is common in the colder north. Open: it is OK to surround some wooden pens within a certain range, but the disadvantage is that it is difficult to control the pigs and is only suitable for the south where the climate is warmer. Closed: often in the form of single-row closed, double-row closed and multi-row closed, one or more rows of pig pens are arranged in front of each row of railings, and there is a pigsty in the middle between the corridor and the corridor, which is often seen in large pig farms.
If you want to raise pigs well, you have to build a pigsty before raising pigs. a good pigsty is usually very beneficial to raising pigs, so there are actually many ways to build a pigsty in rural areas. for example, big shed, open, closed, each has its own advantages.
Construction method of Piggery in Rural areas
There are many kinds of rural pigsty construction methods, usually based on these three types: large shed pigsty, open pigsty, closed pigsty.
The main contents are as follows: 1. The pigsty is mainly made of large sheds and plastics. the pigsty uses the sunlight from the outside to increase the temperature inside the pigsty. In colder places, pigs are usually raised in this way, such as the most common in the north. Usually this kind of investment is not very much, and the effect is ideal. First, the approximate frame of the pigsty is set up and plastic is put on the top.
2. The construction method of an open pigsty is simpler, just surround some wooden pens, which saves costs and materials very much. Usually, this kind of lighting is better, and it is easy to eliminate harmful gases, but it also has some shortcomings. Because the pigsty is not closed, so the temperature in the pigsty changes with the weather, which is not easy to control. This is very cold in the north, and it is very unsuitable for breeding. Usually this kind of pigsty can only be found in warmer places.
3. Closed pigsty is usually built in the form of single-row closed, double-row closed and multi-row closed. Usually, one to several rows of pig pens can be set up in front of each row of railings. The corridor is simple in structure, and there is a pigsty in the middle between the corridor and the corridor. Usually this kind of lighting is better, ventilation and moisture-proof effect is also very good, suitable for places where the temperature difference is small and winter is not very cold.
To build a pigsty in rural areas, you need to decide how to build it according to the local climate. For example, the local winter is relatively cold. Usually, this kind of pigsty is suitable for closed and large shed construction methods. If the local winter is not very cold, all three methods are possible.

Sow breeding technology
Environment: at about 16-22 degrees, the humidity is about 70% to 80%. Feeding: about 20 days before mating and 10 days after mating, the amount of feed should be increased, and the amount of feed should be reduced by 10% to 20% in the week before production. Give birth: try to allow sows to give birth during the day, so as to have
