1) The annual feeding cost of sows: calculated by 5 kg of feed per head per day, 365 days *5*0.9 yuan/kg * day per year = 1642 yuan, plus some epidemic prevention expenses 100 yuan, and other miscellaneous expenses, up to 2,000 yuan.
Theoretically, a sow gives birth to 2.45 fetuses a year. If you count two nests, the average nest is one 10, so you count eight nests. The cost of a piglet is 2000 yuan/16= 125 yuan/head.
2) Feed cost: Piglets generally eat suckling pig feed (granules) before 30kg, which is calculated as 1kg in 2 yuan and 1.2kg in lactation for 30 days, and the cost of growing to 30kg is 30* 1.2*2=72 yuan, calculated as 80 yuan.
30 kg to 200 kg fattening pigs, fattening pigs eat compound feed (that is, 20% concentrate and 80% corn futures, divided into three stages). Theoretically, the average feed-meat ratio is 3: 1, and the feed used is 3*(200-30)=5 10 kg. No matter how bad the pig farm is, it needs 600 Jin of feed. Feed per catty 1. 1 yuan (corn futures 2.5 yuan *20%+0.6~0.7 yuan/catty *80%= 1.06), namely 660 yuan. Therefore, for a 200 kg piglet, the total feed cost is 660+80=740 yuan.
3) Total cost: 125 yuan (the cost of sows and piglets) +740 yuan =865 yuan.
4) Breeding autotrophic profit: According to the current pig market 6.5 yuan/kg, the breeding profit of a pig is 6.5 yuan/kg *200 kg-the cost is 865=435 yuan, and the profit rate is 50%.

Second, outsourcing pigs.
1) Purchasing cost of piglets: calculated by 50 kg piglets ((the price of such piglets is similar to that of big pigs, calculated by 1 kg 7 yuan), and the purchasing cost is 50*7 yuan =350 yuan;
10 kg piglets may be around 12 yuan, and the purchase cost is 10* 12 yuan = 120 yuan;
2) Feed cost: 50 to 200 kilograms of piglets are purchased and slaughtered, with 450 kilograms of materials, and the poor use 550 kilograms of feed at most. According to feed 1. 1 yuan/kg, the cost is 450* 1. 1 yuan/kg =495 yuan, with a difference of 550 *.
Buy 10 kg piglets: 10 kg -30 kg, gain 20 kg, 20* 1.2*2=48 yuan; 30-200 kg, weight gain 170 kg, consumption 5 10 kg, 5 10 *1= 561yuan, and the difference is calculated as 600 kg, 600 *.
3) Total cost: buy 50 kg piglets: the total cost is 350+495=845 yuan, and the difference is 350+605 yuan =955 yuan.
Buy 10 kg piglets: 120+6 10=730 yuan, and the price difference 120+7 10=830 yuan.
4) Profit from the purchase of piglets (calculated by 6.5 yuan/kg in the hog market):
Buy 50 kg piglets: 6.5*200-845=455 yuan/head, the price difference is 6.5*200-955=345 yuan/head. (4 months of slaughter, 3 batches of breeding)
Buy 10 kg piglets: 6.5*2-730=570 yuan/head, and the price difference is 6.5*2-830=470 yuan/head. (2.4 batches can be cultured in 5 months)
