At present, the energy feeds commonly used in pig industry include corn, wheat, broken rice (including rice) and rice bran. After the energy feed (corn/rice, etc.) is acidified and ground in the animal's stomach, the non-absorbed pods enter the small intestine directly. This is where the real nutrient absorption takes place. It is also the key to determining how fast a pig can grow. The mash (maize mash) is directly hydrolyzed in the small intestine by various "enzymes" into monosaccharides (glucose), and then it is directly decomposed into water and carbon dioxide after entering the blood (blood sugar), generating a large amount of energy for the body. Use; part is stored in the liver as a glycogen, used for direct energy during strenuous exercise; part of it is re-synthesized as fat and stored under the skin for use as a backup energy substance. Which kind of energy feed is best? In fact, the best is broken rice, the highest unit of energy, and digestibility is much higher than (100%) corn, but corn contains about 8% of crude protein, which is stronger than broken rice. If you use broken rice instead of some corn, it will have a good effect, but also reduce feed costs. If all energy feeds use broken rice, pigs cannot consume zeaxanthin in corn, which will affect the meat quality. Therefore, the replacement ratio of broken rice should not exceed 50%.
