Design and supporting facilities of large-scale pig farm

I. Layout of inner fencing in pigsty
Pigs with different genders and different feeding and physiological stages have different requirements for environment and equipment. When designing pig house's internal structure, we should rationally arrange pigsty, walkway and rational organization of feed and fecal transportation routes according to physiological characteristics and biological learning characteristics of pigs. Give full play to the productive potential of pigs, and at the same time improve the labor efficiency of feeding and management workers.

(1) Boar house boars usually adopt the single-row formula with sports ground. Setting up sports ground for boars to ensure adequate exercise can prevent boars from overfertilizing, which is beneficial to their health, improving semen quality and prolonging the life of boars. Boar fence should be wider than sow and fat pig fence. The height of fence is 1.2-1.4 meters and the area is 7-9 square meters. The fence structure can be concrete or metal, which is convenient for ventilation and management personnel to observe and operate.

(2) Vacancy, vacancy of pregnant sow house, vacancy of pregnant sow house can be single-row type (with sports field), double-row type, multi-column type and so on. Limit column is usually used in hurdles. The design of limit column is as follows: the length of column is 1?9 meters, and the height is 1?1 meters. The floor layout of the fence is as follows: the outside of the head of the fence is a brick structure material sink, 1?3 meters of cement floor, 0?6 meters of fecal leak fence, and the slope below the fecal fecal fecal fecal fence is connected with a 0?3 meters wide fecal and urinary ditch. The limit bar is divided into 60 cm and 65 cm in width, of which 60 cm is for primiparous sows and 65 cm is for multiparous sows. Moving fence: Moving fence with 1/2 width moving to the left or right is installed in the head of limit fence. The straight pipe of moving fence is located in the middle line of the head at ordinary times, which blocks the head of pigs, so that the head can not be extended. When sows take drinking water, the fence is moved by 1/2 fence to make the head protrude. Long strip material sink: material sink net width 25 cm, bottom arc, inclination 0.5%, groove depth 20 cm, the outside is 5 cm higher than the inside, the inside is 7 cm below the head. At the bottom of the last fence, near the lowest point, there is a small cement dam about 10 centimeters high. At the bottom of the outside of the dam, there is a small drainage hole connected with the ground open ditch. The small open ditch is connected with the fecal and urinary ditch. In order to facilitate ventilation in summer, a row of 45 *45 cm windows and doors are arranged on the tail wall of the limit bar about 15 cm away from the ground. The tail opening of the limit bar is made of 6-inch steel pipe, 8-inch steel pipe for column and side pipe, and 12-millimeter steel bar for fecal fence. Welding is full welding, generally the thickness of the weld is 3 mm. The pumping equipment is installed on the walls at both ends of the pigsty according to the actual needs, and the height is about 1.7 meters from the ground.
