Abstract
If gastric acidity is to be encouraged, it may be beneficial to eliminate some feed elements from pig starter meals
since they bind more acid in the stomach than others. The cereals (wheat, maize, and barley), soybean meal, commercial
mineral supplement, and two feed mixtures (one of them with the additive Zeolit) were evaluated. In this study, it was
discovered that adding zeolite to the feed mixture had the effect of lowering its initial pH (P<0.001), buffering (P<0.05)
and binding capacity (P<0.05). This study aimed to measure the buffering and acid-binding capacity of some ingredients
commonly used in growing pig feeds and estimate the coefficient of correlation between crude protein, ash, and the
buffering capacity of feed ingredients with significant linear correlation (P<0.05 and P<0.01, respectively). The combined
impact of the individual feed mixture components' individual buffering capacities has not been proven.
