Very interesting topic indeed because so many farms have problems with stomach ulcers. If I understand your article correctly, you do not present any observations on the actual occurrence of ulcers in pigs treated with Sangrovit?
In Denmark, we have observed that particle size and feeding of mash or pelleted feed were the factors contributing the most to the occurrence of gastric ulcers. Farms feeding pelleted feed observe much more frequently ulcers than home mixing farms.
I was wondering if you have done any trials with sows and Sangrovit because ulcers are also a big problem in sows.
According to my experience, it is necessary to focus on the role of many risk factors such as feed structure, disease in breeding, and stress factors, in addition to the price of Vitamin E. With the increase in Vitamin E price, we integrate less and we have ulcer problems. When we have high respiratory problems, ulcers are increasing. If we do not administer material such as straw, wood chips or anything else, ulcers increase.
Sangrovit helps a lot when we have the problem, but we need to review our breeding program.
