Twenty years ago, every family in the countryside used swill to feed pigs. Why can't swill pigs eat now?

The industry of raising pigs can be traced back to thousands of years ago. At that time, the production technology was not so strong, and basically a few pigs were raised at home. In the last century, pigs were widely raised in rural areas. In addition to farming, many farmers also raised pigs and chickens as a sideline. At that time, there was basically no large-scale employment in cities. In addition to being a sideline, I will also kill pigs during the Chinese New Year, and my relatives and friends will come to help.

As early as in the past, there were both scattered pigs and pens in rural areas. Many farmers also feed pigs in their spare time, and some leftovers at home will be taken away directly. In addition, some crops, such as sweet potatoes, will be planted in fields for pigs to eat. Feeding swill to pigs has become a common way in the past. At that time, basically every family was swill pigs, and there was no swine fever. Why can't we feed the swill now?

In fact, in the past, swill was mainly leftovers, and of course there were some soups and leftovers. Suppose that 20 years ago, people's quality of life did not improve, and it was common for every household to have enough to eat. Saving food has become the mainstream, with little waste. But later, when a large number of hotels and restaurants emerged, this kind of swill pig situation would appear in large numbers.

In order to save costs, some small free-range households will buy swill in hotels, and even some small hotels will directly exchange pork with farmers for how much swill they provide each year. As we all know, this kind of swill in the hotel basically has everything. If you look in the kitchen, there will be several vats, in which besides leftovers, there are detergent, cigarette butts and paper towels. In addition, the urban management is poor, and most of the swill will not be taken away on the same day, sometimes it will stay overnight, and it is more likely to rot and deteriorate in summer. How can these things be fed to pigs?

In fact, waste utilization is indeed a good thing, but there are great security risks in this practice, and the growth of pigs will be affected to some extent after eating, especially after being slaughtered, the meat is smelly and firewood. I don't know if you have bought that kind of uncooked pork with strange taste, most of which are pigs fed with swill. Therefore, the current swill cannot be confused with the previous swill. After all, the gap between the two is different. At present, swill is basically kitchen garbage in hotels, while the previous swill was leftovers for pigs. At present, there are few swill pigs in China, and with the influence of African swine fever, you can't feed swill indiscriminately if you want to keep your pig farm.
