Determination of buffering capacity of the selected feeds used in swine nutrition

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.
