Damage to pigs caused by moldy corn is commonly manifested by reduced feed intake, especially for farmers who use concentrates. Due to improper conservation of their own corn harvest, pig feed intake is often reduced drastically. If moldy corn produces corn With ketene toxin, pigs will show erythema and other similar estrus performances, regardless of whether they are young sows, pregnant sows or castrated sows. In severe cases, they will suffer miscarriage and infertility. With the decrease in feed intake, the use of mold adsorbents will improve significantly. There is no obvious effect on the miscarriage and infertility of pigs using mold adsorbents. If this happens, farmers will need to adjust the feed formulation in a timely manner and try to use wheat, broken rice and other raw materials instead of corn to avoid more serious production losses.
