If the daily feed is calculated as 5 kg/head, the feed used by sows is relatively cheap, which is about one kg in 0.9 yuan, 365 days *5*0.9 yuan/kg = 1642 yuan, plus the epidemic prevention cost 100 yuan or other expenses, at most, it is calculated as 2,000 yuan, and one sow can litter 2 times a year.

2. Feed cost

Pigs usually eat suckling pig feed (granular feed) before 30 kg, and the feed is calculated according to one kg in 2 yuan. Before 30 kg, they are basically still in the lactation period. It's almost like eating a kilo of feed and growing a kilo. According to 1.2 kilo, it costs 30* 1.2*2=72 yuan and 80 yuan. 30 kg to 200 kg fattening pigs eat compound feed.

Theoretically, the average feed-to-meat ratio is 3:1,that is, when 30 kg grows to 200 kg (200-30= 170), 5 10 kg feed is used, even in poor pig farms, 600 kg feed can grow to 200 kg.

The feed rate is 1. 1 yuan per catty (feed concentrate 2.5 yuan *20%=0.6+ corn 0.7 yuan/kg *80%=0.56 yuan, which is actually 1.06 yuan), and eating 600 kg of feed is also 660 yuan, that is to say, raising one head will grow to 200 kg.

3. Profit analysis

125 yuan (the cost of sows giving birth to piglets) +740 yuan =865 yuan. If calculated according to the market price of 7 yuan, the profit is 7 yuan * 200kg = 1400 yuan, and if the cost is 865 yuan, a profit of 535 yuan can be obtained, then 100 pigs can earn 53,500 yuan.

Essentials of raising pigs in winter

1, pigsty peripheral wall should be thick and tight.

Thermal insulation facilities should be added to the back wall, gable and front wall of the pigsty in winter. To this end, crop straws can be piled up and clay blanks can be temporarily built. It is best to thicken the walls around the pigsty when it is first built. Old piggery should seal the residual gaps of walls, doors and windows in time.

2. Raise the temperature of the pigsty

There are many ways to raise the temperature of pigsty, but there are four economical, simple and practical ways.

First, the open pigsty is covered with plastic film. It is best to cover with double-layer plastic film, although the cost is higher than that of single-layer plastic film, but the heat preservation effect is better. This method is suitable for pig houses and non-lactating sow houses. Second, the closed pig workshop implements boiler heating. The third is the open pigsty heating and plastic film covering. Fourth, heating and electric heaters are suitable for nursing sow houses.

3. Add a bed board

In the piglet stage, where conditions permit, it is best to use warm bed boards such as wooden boards, bamboo boards and thickened fiberboards, but cement prefabricated boards can be laid when conditions permit.

4. The pigsty floor should be dry.

Fecal sewage should be removed in time and cleaned up. In order to facilitate drying, pigsty can be made into cement floor, but pigs on cement floor are prone to catch cold and white dysentery. To solve the disadvantages of cement floor, floor heating is used, which can effectively ensure the overall temperature of pigs, rather than the local temperature. Floor heating electric heating film is widely used in pig houses.

5. Don't let pigs drink cold water.
