How much does it roughly cost to invest in a small pig farm?

For a small pig farm raising 6 sows and 30 commercial meat pigs, simple pig sheds can be built in an orchard, on a hillside woodland, or beside a reservoir or pond, with pigs kept in pens, or an old house can be converted into a pig shed. The pig shed should have plenty of sunlight, high and dry terrain, and convenient drainage. A small ecological pig farm needs a breeding pig shed, a fattening pig shed, a feed processing room, a feed production room, and a dormitory.

Building plan for a small pig farm

1. Breeding pig shed: Use ground-level pen raising; an ordinary idle house can be converted, or a new one can be built. A newly built breeding pig shed with a brick-stone and asbestos tile structure has 6 rooms, designed with an indoor area of 6 square meters and an outdoor activity yard of 9 square meters per room. The outdoor activity yard wall is 0.8 m high, and each sow is kept in a single room. If an old house is converted into a pig shed, the window area should be doubled compared with an ordinary dwelling, or it should be changed to a half-wall open-shed structure.

2. Fattening pig shed: Brick-stone and asbestos tile structure, 3 rooms, designed with an indoor area of 12 square meters and an outdoor activity yard of 18 square meters per room. The outdoor activity yard wall is 0.8 m high.

3. Other losses: Feed processing room, feed production room, and dormitory, 4 rooms in total, 10 square meters each, with a brick-stone and asbestos tile structure.

Investment cost of a small pig farm

1. Construction cost: The breeding pig shed is a brick-stone and asbestos tile structure with 6 rooms totaling 36 square meters, at 70 yuan per square meter, totaling 2520 yuan. The fattening pig shed is a brick-stone and asbestos tile structure with 3 rooms totaling 36 square meters, at 65 yuan per square meter, totaling 2340 yuan. The feed processing room and feed production room are 3 rooms totaling 30 square meters, at 60 yuan per square meter, totaling 1800 yuan. One small feed grinder costs about 400 yuan, one electric motor 400 yuan, one small feed handcart about 200 yuan, feed production tools 400 yuan, and materials for enclosing the activity yard 800 yuan, totaling 2200 yuan. One simple dormitory costs 800 yuan. The total investment in pig farm construction is 9660 yuan.

2. Breeding stock cost: 6 local improved pre-breeding sows, each weighing 20 kg, totaling 120 kg, at 20 yuan per kg, totaling 2400 yuan.

3. Other costs: Water, electricity, tools, epidemic prevention and disinfection drugs total 1000 yuan. Boar semen costs 10 yuan per dose, 2 doses per repeat mating, 2 litters per year, totaling 240 yuan. Feed working capital 4000 yuan. Unpredictable expenses (the sum of items 1 to 5 above × 15%) total 2595 yuan.

4. Investment cost: The above items total 19,900 yuan, and the investment estimate is taken as 20,000 yuan.

Economic benefits of a small pig farm

1. Annual income: Meat pigs are sold at an average weight of 95 kg per head from birth to 6 months, at 11 yuan per kg, and 60 commercial meat pigs bring in 62,700 yuan. Sixty piglets are weaned at 35 days and raised for another 25 days, then sold at an average weight of 18 kg per head at 60 days, at 16 yuan per kg, and 60 commercial piglets bring in 17,280 yuan. In that year, selling commercial meat pigs and piglets in batches brings a total income of 79,980 yuan.

2. Cost expenditure: Ecological grain-saving farming is adopted, supplementing with artificially bred live insect feed and mineral additives, with very little commercial concentrated feed input. Self-mixed feed costs 1.8 yuan per kg. Each commercial meat pig weighs 95 kg, and 60 commercial meat pigs total 5700 kg. With a feed-to-meat ratio calculated at 3.5:1, the total feed cost is 35,910 yuan. The 6 sows (including piglet suckling) consume 5475 kg of feed for the whole year, with a total expenditure of 9855 yuan. In addition, each piglet is supplemented with 10 yuan of creep feed, totaling 1200 yuan, and the total feed cost is 46,970 yuan. Live feed production cost is 800 yuan, water and electricity 1200 yuan, tools 300 yuan, and epidemic prevention and disinfection drugs 800 yuan in total.

3. Economic benefits: Total expenditure is 50,070 yuan. With income and expenditure offset, a profit of 29,910 yuan can be made that year.

Notes for a small pig farm

1. Promote the new ecological grain-saving pig farming model of “pig - biogas - EM - maggots - earthworms - green feed.” The rearing environment is good, live feed is sufficient, the feed self-sufficiency rate is high, and the cost of self-mixed feed is controlled below 1.8 yuan per kg.

2. Breeding and rearing techniques should be up to standard. Commercial meat pigs at 6 months of age should average more than 95 kg per head, and piglets at 60 days of age should average more than 18 kg per head.

3. Market the pigs on time and minimize intermediate sales links as much as possible. If selling to pig dealers, profits will be reduced by 1/3 to 1/2. If deep processing of feed grain can be carried out (such as brewing corn into liquor first and making soybeans into tofu first), and then the processing by-products (distiller's grains and tofu residue) are used to feed pigs, profits can also increase substantially.
