Four small pigs
In this project, we have four different pig farming models, each with distinct production structures, feeding methods, and profitability. Let's go through them one by one.
**Model 1: Small Batch Rearing with Annual Slaughter of 40 Pigs**
The planting structure includes 6,000 square meters (9 acres) of corn, 1,300 square meters (2 acres) of soybean green, and 2,000 square meters (3 acres) of double-cropped soybean green. Piglets weighing over 7 kg are purchased in January, February, April, and May, with 5 pigs per batch. From the end of the fourth month, 5 pigs are slaughtered monthly, and 5 new ones are added after each slaughter. The feeding is done in stages over 120 days. Annually, 8 batches of 40 pigs are sold, with an average weight of 85–90 kg. Each pig generates income between 2,500–3,200 yuan, with a profit of 250–500 yuan. Total annual income ranges from 20,400 to 250,000 yuan, with profits between 2,000 and 4,000 yuan.
**Model 2: Rotational Breeding with 60 Annual Slaughters**
This model involves raising pigs every other month, resulting in 60 pigs slaughtered yearly. The planting area consists of 8,670 square meters (13 acres) of corn, 2,000 square meters (3 acres) of soybean green, and 3,330 square meters (5 acres) of double-cropped soybean green. Piglets over 7 kg are bought in January, February, April, June, July, and September, with 10 pigs per batch. Feeding is divided into stages, and pigs are slaughtered at 110–120 days. There are 6 batches annually, with each batch averaging 90 kg live weight. Revenue per batch ranges from 5,300–6,500 yuan, with a profit of 500–1,000 yuan. Annual revenue reaches 31,800–3.9 million yuan, and profit ranges from 3,000 to 6,000 yuan.
**Model 3: Four-Batch Rearing with 80 Annual Slaughters**
This model involves four batches per year, with 80 pigs slaughtered annually. The planting area includes 1.2 hectares (18 acres) of corn, 2,660 square meters (4 acres) of soybean green, and 4,000 square meters (6 acres) of double-cropped soybean green. Piglets over 7 kg are purchased in January, March, June, and September, with 20 pigs per batch. Feeding is divided into three stages, and pigs are ready for slaughter in 110 days. With 4 batches annually, each batch averages 90 kg. Revenue per batch is between 10,600–1.3 million yuan, with a profit of 1,000–2,000 yuan. Annual revenue totals 42,400–5.2 million yuan, and profit ranges from 4,000 to 8,000 yuan.
**Model 4: Self-Breeding with 100 Annual Slaughters**
This model focuses on self-breeding, with 100 pigs slaughtered yearly. The planting area includes 1.6 hectares (25 acres) of corn, 4,670 square meters (7 acres) of soybean green, and 5,330 square meters (8 acres) of double-cropped soybean green. Good breeding sows are purchased in January, bred in June, give birth in October, and enter the breeding cycle in November. The herd size is maintained at 50 pigs every 5 months. Feeding is stage-based, starting from piglet to slaughter at 150–160 days. Over 5 years, 540 pigs are slaughtered, with 110 pigs per sow annually. Slaughtering every 5 months brings revenue of 26,500–2.9 million yuan, with a profit of 2,500–5,000 yuan per batch. With 2.5 batches annually, total revenue reaches 66,000–7.2 million yuan, and profit ranges from 5,500 to 11,000 yuan.
