The cost of raising pigs mainly includes the cost of pig houses, feed costs, veterinary drugs and disinfection costs, and labor costs. The cost of selling a pig for slaughter is about 1,000 yuan to 1,300 yuan. The slaughter weight of pigs is about 250 kilograms to 300 kilograms. Based on the market price of 10 yuan per kilogram, the profit of a pig is about 2,000 yuan.

Based on the market price of 25 yuan per catty, 12.5*250 catties = 3125 yuan; 3125 yuan-1100 yuan = 2025 yuan. That is, if based on this price, raising 1,000 pigs can earn 1,000*2025=2,025,000 yuan. That is, the annual profit from raising 1,000 pigs is approximately 2,025,000 yuan.
