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 was 50-60 kilograms, the high-energy fine material was added to assault. This feeding method, due to the lack of protein and mineral elements required for the growing period of the pig, is fed for more than one year. Since the amount of feed consumed for maintaining the breeding is too much, it will result in the increase of concentrated feed and waste. The other is the “one-stop†feeding method. This method has been used for keeping feeds from pigs to slaughter. This shortens the feeding cycle and reduces the consumption, but the green and rough feeds are not fully utilized. The “pour-feed†method of raising pigs is to use high-energy, high-protein concentrates from the pigs to the middle-pigs, ie, 50-60 kg, with the necessary feed additives and a small amount of green and rough feeds. In the mid-to-slow period, the amount of concentrate input is appropriately reduced, and green and rough feeds are added. The proportions are: concentrate feed 60%, green feed 25%, and roughage 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.
It is specially used to draw this kind of ordinary insulin. The scale on the syringe is more accurate, because it needs to draw insulin according to 0.1ml or a finer scale, so its scale is relatively small. And the needle tube is thinner
