Recently, through long-term observation and research on the living habits of pigs, it has been proved that pigs are kind, docile and intelligent animals. It is neither as obedient as cattle and horses, nor as overbearing and fierce as goats; Neither ungrateful like a cat, nor flattering like a dog. In many ways, dogs are not as clever as pigs. After training, pigs can not only master various skills and movements like dogs, but also have shorter training time than dogs. Some specially trained pigs can dance, drum and swim; Some will push the car straight; Some clever pigs can also be "pigs and dogs"; Some people can even sniff out mines buried in the soil with their noses.
Pigs can also be guards like dogs. In the United States, some farmers use pigs to defend the land of the manor, and also bite strangers who have strayed into the manor. Another farmer raised two pigs to guard the pond instead of people in order to prevent cattle from being bitten by snakes when drinking water by the pond, and achieved good results. Pigs can not only prevent snakes, but also like to eat them. Scientists have proved through experiments that it is scientific to raise pigs to prevent snakes, because pig fat is thick, which can neutralize snake venom and prevent snake venom from entering blood vessels.
The sense of smell of pigs is also very developed. In some parts of France, an expensive edible fungus black truffle grows underground. Local farmers regard pigs as powerful assistants for harvesting black truffles. Pigs can smell black truffles growing 25-30 cm underground from 6 meters away. Although dogs can also undertake this job, it is much more difficult to train dogs than pigs, and they have to be searched every day. If they are separated by a few days, they will forget. In this respect, pigs are much more capable than dogs. Even if it only searches once a week, it won't forget the skills it has learned.
Pig is an athlete on the playground. A few years ago, at the national farm exhibition held in the United States, a unique pig race was held. At the referee's command, the pigs with tags run one after another, and they will make a final sprint when they are near the finish line.

[Edit this paragraph] Scientific pig raising method
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. Promote high-density pig breeding. 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 space, love to gain weight quickly and reduce feeding expenses.
After fattening pigs exceed 90 kg, the daily weight gain rate is obviously slow down, and fat deposition is the main factor, so the more you feed, the more uneconomical it is, and the more fat it is, the harder it is to sell. Slaughtering under 90 kg, although the feed utilization rate is high, is uneconomical because of its small weight and low meat yield. Generally, 90 ~ 120 kg slaughter is most suitable for fattening pigs.
4 varieties should be excellent. 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.
Column 5 should be simple. Don't make the pigsty too luxurious, just keep warm and ventilated.
6 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.
7 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.
8 slaughter should be timely. For example, when the resting weight of binary pig reaches 70kg, the inner ternary 80-85kg and the outer ternary 95kg, and the British PIC pig 105kg, it is the appropriate 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.
"Feed-back" pig-raising method is a new type of pig-raising method based on the above shortcomings and the growth law and characteristics of pigs. This method is in the stage from piglet to middle pig. That is, before 50-60 kg, concentrate with high energy and high protein is the main material, supplemented by necessary feed additives and a small amount of green feed. From the middle pig to the slaughter stage, the input of concentrated feed should be appropriately reduced, and the ratio of green feed to roughage should be increased: concentrated feed 60%, green feed 25%, roughage 15%. This method not only shortens the feeding cycle of pigs, but also makes full use of a large number of green feed and roughage resources, thus saving the amount of concentrated feed and greatly improving the economic benefits.
