Assessment of the Degradability of Various Soybean Products in Cows and Buffaloes Using In-Vitro and In-Situ Methods

Abstract

This study evaluated the in situ and in vitro degradability of three soybean products; soybean meal (SM), full-fat soybean (FFS) and soybean flakes (SF) using cannulated Brown Swiss cows and Crossbred female buffaloes. Samples of soybean products were incubated in nylon bags for 4, 8, 12, 16 and 24 hours in the rumen to determine the degradability of dry matter (DM), crude protein (CP), Ether Extract (EE) and organic matter (OM). In addition, in the second stage of the study, a Daisy incubator was used to determine the in vitro true digestibility of soybean products for 48 hours. In situ, 24-hour DM and CP digestibility in SM, CF digestibility in FFS, and OM were higher in SF at buffaloes. Buffaloes exhibited superior kinetic degradability in FFS, while cows showed better performance in SF. In vitro analysis using a Daisy incubator confirmed that, there were no notable species differences for FFS, but higher degradability for SM in cows and SF in buffaloes. In summary, in the rumen, cows showed faster initial DM degradability, while buffaloes had a higher rate in later stages, with buffaloes also excelling in CP digestibility and CF degradation of high-fat feeds.
