What is the most reasonable design for a sow pen? Sow pen size introduction

Calculating with the feeding area of 2.5m2 a sow, the feeding capacity is under 200 heads, you can set up 1 pen, 200 sows for 1 pen unit, which is 500m2 sow pen.

The activity area of the sows is 3m2, the length and width are 2m and 1.5m respectively, the outdoor activity area is about 2m2, the length and width are 1.5m and 1.3m respectively, and the height of the pigsty fence is about 1.1-1.2m.

I, sow pen how to design the most reasonable

1, design scale

(1) can be based on individual economic conditions and management capacity, to 2.5m1 sow feeding area, feeding capacity in the following 200, you can set up 1 enclosure, 200 sows for 1 enclosure unit, is 500m of sow enclosure.

(2) 500m of pen can be mixed with 200 sows, or can be divided into 1 single pen for every 125m, if feeding 50 sows, so 500m can be divided into 4 units, 1 feeder for every 1 pen, and at the same time, farrowing house can be built separately.

2. Feeding method

(1) Generally use the big circle for feeding, the number of sows kept in the big circle is 200 sows, which can be mixed with empty pregnancy and gestation sows, and 4 single units are set up for 1 group, and then set up the separation system, and the big circle is set up with the resting area, feeding area, activity area, and separation area, and at the same time, there is the area for oestrus identification, and a boar is set up in the area of oestrus identification, and the oestrus identification system can be installed in the middle of the circle. Installation of estrus identification system.

(2) If you use a small circle for feeding, you need to separate the pregnant and gestating sows, every 50 pigs for 1 pen, without using the separation system, usually identify the state of the sows, generally available artificial observation system of the color spraying device, if the number of days of pregnancy to 105 days of the pig's back sprayed red, estrus sprayed yellow, 1 day without eating sprayed blue, estrus identification system is set up next to the empty sows, the circle is set up in the middle of the estrus identification system, and there is one boar in the circle. The estrus identification system is set up next to the empty sow house, and there is 1 automatic waterer of 15-40cm in the circle.

3, the way to clear feces

(1) After the sows are transferred to the barn, they need to be trained to excrete at regular intervals, and the feces will be cleared by the feces removing mouth to the feces truck and pushed away regularly every day, and they can't be piled up under the feces removing mouth in front of the barn to contaminate the walls and the ground, and the pig's urine and the sewage will flow into the sewage ditch in front of the barn by the floor drain which is covered with a cover plate.

(2) sewage ditch in each house at the end of the 1 set of sedimentation tank, supernatant flow into the pig farm total sewage pipe to the sewage tank, generally by strict oxygen, aerobic and sand considerations or artificial wetlands after discharge.

4, fence wall design

Generally, the south fence wall is 24 brick cement touching the surface of the lattice prismatic wall, the back corridor of the through-length fence wall for the iron railing, the north wall needs to be set up on the window and ground window, conducive to summer ventilation, the adjacent two columns of the fence for the brick cement touching the surface of the wall of the 12, to prevent the spread of contact epidemics of pigs in the two neighboring columns.

5, environmental control measures

(1) generally in the summer part of the open south of the pigsty, need to use plastic mesh or sunshade sealed, not only ventilation and can block flies, winter covered with plastic film for insulation, including the north and south lattice prismatic wall, the house of the dirty air from the roof vent, in the summer using the pavilion effect, the use of the greenhouse effect in the winter, can basically meet the environmental temperature requirements of the fattening pigs. The environmental temperature requirements of fattening pigs.

(2) When the temperature is too high at noon in summer, it is necessary to pull the plastic pipe above the pen, and install 1 plastic nozzle in each pen for spraying and cooling, but during the period of farrowing and piglet nursery, it is not possible to spray and cool down, so as to avoid dampness of the pig house, and the piglets get dysentery, and in general, the upper window of the north wall of the pig house and the ground window, which is needed to be sealed with the plastic mesh in summer, and sealed and kept warm with the plastic film in winter.

Two, sow positioning pen size

1, piglet insulation area of about 1.5m, length and width of about 1.2m, the need to add lighting, the sow's activity area of 3m, the length and width of 2m and 1.5m, respectively, need to install the feeding and drinking devices.

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