Extended data

1, cultural points

(1) for protective feeding.

In summer and autumn, planting gourd, big melon, sleeping melon, sunflower and other plants outside the pig house can shade and cool down. In winter, plastic greenhouse feeding technology should be popularized, and insect repellent and immunization work should be done regularly.

(2) Develop high-density breeding pigs.

0.8m2 pigpen in winter 1 fattening pig, summer 1 pigpen 1 fattening pig. High-density breeding pigs not only have few laps and low cost, but also fatten pigs compete for food. Sleep when there is no activity place, love to gain weight, gain weight quickly, and reduce feeding expenses.

(3) the variety should be superior

First of all, we should choose varieties according to market demand. At present, it takes at least three yuan, preferably five yuan, to popularize multiple hybridization For example, the British PIC pig, five lines, has a fast growth rate, and can reach 1 10 kg in 58 days, with a lean meat rate of 66% and a feed-meat ratio of 2.8: 1.

(4) The fence should be simple.

The pigsty can be cold-proof, warm and ventilated.

(5) Feed should be cheap.

Feed accounts for 70 ~ 75% of the cost of raising pigs. Feed formula should change with the change of market price and season, and cannot be fixed. If pigs eat less in hot summer, the feed should be more nutritious. Feed nutrition should be balanced to meet the growth needs.

(6) Epidemic prevention should be strict.

Pay attention to disinfection, not only to prevent foreign diseases, but also to prevent fecal pollution and spread diseases, and inject vaccines according to immunization procedures.

(7) delisting should be timely.

For example, the weight of binary pig reaches 70 kg, the inner ternary is 80 ~ 85 kg, the outer ternary is 95 kg, and the British PIC pig 105 kg is the timely weight for slaughter. In addition, when the pig market price is high, the heavier the weight, the better; When the price is low, it's best to be light, so as to reduce feed consumption and cost.
