1. Corn varieties
At present, there are two types of domestically produced corn. One is called concave corn when it matures and is called concave corn. It is mostly produced in the northeast; the other is called convex corn (or hard corn) when the top is convex when mature. Produced in some areas. Concave corn is easier to digest than convex corn, so if the pig farm uses convex corn, it is recommended that the particle size be finer when crushing, which is more conducive to the absorption of protein in the feed.
2. Corn quality
Corn is now contaminated by mold in most parts of the country. In addition to producing mycotoxins that cause irreversible damage to pigs, mold also consumes a large amount of energy in corn. Crushing contaminated corn to feed weaned piglets will cause poor protein absorption and utilization due to insufficient energy in the feed. diarrhea.
3. The crushed particle size of corn
Since the digestion and absorption capacity of the gastrointestinal tract of sows and piglets are different, the recommended feed size for piglets is 0.8-1mm, 1.5-2mm for middle pigs, and 2-2.2mm for large pigs and sows. In the nursery stage of pigs, the digestive system is not fully developed, the secretion of digestive enzymes in the gastrointestinal tract is insufficient, and the feed size is too large, and the piglet feces will be found to be yellow and thin, containing a large amount of undigested corn pellets, which not only wastes feed, but also causes The incidence of piglet diarrhea increased. However, since the digestive system of Zhongda pigs has been fully developed, feeding too small a particle size can cause stomach ulcers in sows.
To prevent post-weaning diarrhea in piglets, first consider the problems of feed ingredients (including corn varieties, quality and particle size), and then consider adding drugs such as ********* to the feed for prevention.
