"Pour-feeding" pig raising is a new type of pig raising method that aims at the above shortcomings and incorporates the growth patterns and characteristics of pigs. This method uses high energy and high levels before the pigs reach the middle pig class, ie 50-60 kg. The protein concentrate is predominant, with the necessary feed additives and a small amount of green and coarse feeds. In the mid-to-slow period, the amount of concentrate input should be appropriately reduced, and green and roughage should be increased. The ratio is: concentrate feed 60%, green feed 25%, and vinegar feed 15%. This method not only shortens the feeding cycle of pigs, but also makes full use of a large amount of green and rough feed resources, thereby saving the amount of concentrate feed and greatly increasing the economic benefits.
New pig raising method - feeding
At present, most pigs adopt two methods. One is the "hanging shelf" feeding method. In the early stage, a large amount of green and roughage were used, and the amount of fine material was small. When the pig grew to 50-60 kilograms, the high-energy fine material was added to assault. Although this feeding method utilizes a large amount of green and roughage feeds, due to the lack of protein and mineral elements required for the growing period of the pigs, the feeding period is over one year. The increase in feed is wasted. The other is the “one-stop†rearing method. This method has been used for keeping feeds from pigs to slaughter. This greatly shortens the feeding period and reduces the consumption. However, a large amount of green and roughage in rural areas cannot be fully utilized, so the benefits are not. high.
