Can excess starch in the diet of a ruminant lead to rumen alkalosis?

Yes, excess starch in a ruminant's diet can lead to rumen alkalosis, although it is more commonly associated with acidosis. High starch levels can cause rapid fermentation, resulting in an overproduction of volatile fatty acids and a drop in rumen pH. However, if there are fluctuations in diet or other factors that lead to a decrease in fiber and subsequent shifts in microbial populations, it can potentially disrupt normal rumen function and create alkaline conditions. Proper dietary balance is essential to maintain rumen health.
