Can Associative Effects Affect In Vitro Digestibility Estimates Using Artificial Fermenters?

We aimed to test the associative effects among forages, and between forage concentrates on in vitro digestibility of dry matter neutral detergent fibre using an artificial ruminal fermentation system. The study consisted two assays, which were evaluated three sugarcane, maize silage, Tifton 85 hay under incubation conditions (single feed or all feeds together a jar), sugarcane soybean meal and/or ground maize. For first assay, increased (p < 0.02), whereas silage decreased 0.01) when forages incubated same jar. was not altered ≥ 0.57) by condition. In second depressed 0.05) along with grain. both pattern repeatability for estimates presented influence concluded that different jar fermenters causes them. These can alter their repeatability.
