First, the overall planning of pig
Standardized pig farms according to the production of "all in all out" in the water management process to plan, first determine the number of various types of pigsty according to production management processes, and then calculate the number of buildings of various types of pig, to finalize all kinds barn layout arrangement.
1. All kinds of computation required number of pigsty
Production management of different processes, various pigsty number is different, the required number of various types of pigsty roughly according to the following formula:
Pregnancy, maternity homes pigsty number = annual nest count × pregnancy Scotia feeding time ÷ 365
Farrowing pigsty number = annual farrowings × ÷ 365 farrowing feeding time
Breeding homes pigsty number = number × breeding nest year round delivery time ÷ 365 ÷ rearing livestock count each column
Reserve homes pigsty number = annual update to update the first few × ÷ 365 ÷ pig feeding time keeping head count of each column
Species male pig breeding sows bar = annual average number ÷ 15 (or 20)
The number of nursery pigs bar = annual farrowings × nest level weaned nursery feeding time × ÷ livestock count each column 365 ÷
Pigsty than at each stage calculate the number of 10%, that the resulting number is multiplied by 1.1 times, to leave some room for production scheduling, and easy to manage.
2. Number of buildings of various types of pig
After calculating the number of various types pigsty, and then according to the specifications and defecation trenches, walkways, breeder duty specifications of various types pigsty, you can calculate the size and construction of various types of barns several buildings need.
3. barn layout and internal planning
According to the production process, will make all kinds of pig production area layout arrangements. To facilitate the management, shortening the distance transfer group, should be centered maternity homes, maternity homes near nursery, baby nursery barn near, and then next to the young pig pig homes, pregnancy (breeding) should also be close to the farrowing house. In the same production line, the length of each pig should be basically the same, not too long, to 60 to 80 meters is appropriate. Pig too long will the sewage, feeding and mechanical desludging inconvenience. The width of pig preferably within 15 meters, is conducive to building, lighting, ventilation and insulation. Breeding sows homes column should be aligned relative or neighbor to facilitate stimulate oestrus. In order to facilitate cleaning and disinfection and implement all in all out, try to do 24 bar maternity homes as a unit, nursery 12 column as a unit, and isolation between units, then try to do 24 other pig bar or 12 bar for a groups. Barn interior layout and equipment involved in the details of the lot, a few suggestions can be multi-scale field site visits, learn from each other, after a comprehensive analysis and comparison, and then make a detailed planning and design.
Second, the size of the farm's zoning plan
1. production area
Including pig, sterilization room (dressing, bathing, disinfection), disinfection tank, pharmacy, veterinary room, a pig units, maintenance and warehouse, duty and so on. Production area is the main area of farms, 70% to 80% of the total area of general construction. Which kinds of requirements and other pig pig separated to form breeding area. To avoid foreign transport vehicles entering the venue, each pig feed by picking the library door, inside the car with the delivery and installation on the walls of the set of pig units, set up a dedicated pool disinfection sterilization occasionally at the entrance to the production area.
2. production Auxiliary Area
Including feed mills and warehouses, water towers, wells room, boiler room, transformer room, garage, slaughter plants, repair shop, production assisted by favorable quarantine area and facilitate cooperation arrangement with the production area.
3. Management and living area
Including office, canteen, staff quarters and so on. Management and living areas should be built on high, upwind. Working closely with the daily feeding area, not far away from the production area.
4. isolated homes, excreta disposal area
App includes a processing chamber, sewage treatment (or biogas) facilities, these buildings should stay away from the production facilities and living area, located downwind, low-lying areas, in order to avoid the spread of diseases and environmental pollution.
