How to design the sow pen is the most reasonable? the size of the sow positioning bar is illustrated by the picture.

According to the feeding area of 2.5m ²sow, if the feeding quantity is less than 200, one enclosure can be set up, and 200 sows are one enclosure unit, which is the sow yard of 500m ². The living area of the sow is 3m ², the length and width are 2m and 1.5m respectively, the outdoor active area is about 2m ², the length and width are 1.5m and 1.3m respectively, and the height of the pig pen is about 1.1-1.2m.

First, how to design the sow pen is the most reasonable

1. Design scale

(1) according to individual economic conditions and management capacity, it can be calculated on the basis of the feeding area of 2.5m ²1 sow, and the feeding quantity is less than 200, and one enclosure can be set up, and 200 sows can be set up as one enclosure unit, which is the sow pen of 500m ².

(2) A 500m ²enclosure can be mixed with 200 sows, or it can be divided into 1 lap per 125m ², if 50 sows are fed, so that the 500m ²can be divided into 4 units, with one feeder for each enclosure, while the delivery room can be built separately.

2. Feeding mode

The main results are as follows: (1) generally, the large circle is used to feed 200 sows, which can be mixed with pregnant sows, and four single sows are used as a group, and then a separation system is set up. The large circle is provided with rest area, feeding area, activity area and separation area. At the same time, there is an estrus identification area, a boar is set in the estrus identification area, and the estrus identification system can be installed in the middle.

(2) if you are feeding in a small circle, you need to separate the empty sows from the pregnant sows, and every 50 pigs are divided into one cottage without using a separation system. Usually, the color spraying device of the manual observation system can be used to identify the status of the sows. If the pig is sprayed red on the back of the pig on the 105th day of pregnancy, the estrus spray color is yellow, the estrus spray color is blue for one day, and the estrus identification system is set next to the empty sow house. There is a 15-40cm automatic drinking fountain in the circle.

3. The way of removing feces

(1) after the sows are transferred, they need to be trained to defecate at a fixed point, and the feces should be cleared from the manure removal mouth to the manure cart at a regular time every day, and the walls and floor should not be contaminated under the manure cleaning mouth before the house. Pig urine and sewage flow from the floor drain into the sewer with a cover on the front of the house.

(2) the sewer is provided with a sedimentation tank at the first end of each house, and the supernatant flows into the main sewage pipe of the pig farm to the sewage tank, which is generally discharged by strict oxygen, aerobic and sand or constructed wetlands.

4. Fence wall design

Generally speaking, the brick concrete grid wall with the south fence wall of 24, the long fence wall of the rear corridor with iron railing, the north wall with windows and ground windows, which is conducive to summer ventilation, and the brick concrete wall with 12 adjacent columns to prevent the spread of pig contact disease in the adjacent two columns.

5. Environmental control measures

(1) generally, in the south open part of the pig house in summer, it needs to be sealed with plastic net or sunshade net, which can not only ventilate but also prevent mosquitoes and flies, and is covered with plastic film for heat preservation in winter, including north and south grille walls, where dirty air is discharged from the roof vents, and the ambient temperature requirements of fattening pigs can be basically met by using the pavilion effect in summer and Greenhouse Effect in winter.

(2) when the temperature is too high at noon in summer, it is necessary to pull a plastic pipe at the top of the barn and install a plastic sprinkler in each column for spray cooling, but the piglets and piglets should not be sprayed to cool down during the conservation period, so as to avoid the dampness and dysentery of piglets. The upper window and floor window of the north wall of the general piggery need to be sealed with plastic net in summer and sealed with plastic film in winter.

2. The size of sow positioning bar

1. The heat preservation area of piglets is about 1.5m ², the length and width are about 1.2m, and lighting is needed. The active area of sows is 3m ², the length and width are 2m and 1.5m respectively, and feeding and drinking water devices need to be installed.

2. The outdoor activity area is about 2m ², the length and width are 1.5m and 1.3m respectively, and the height of the pig pen is about 1.1-1.2m.
