This experiment aims to determine how the frequency of feeding whole-crop oat forage at different maturities affects intake and ruminal fermentation in heifers.
Used a 2 × 2 factorial within a 4 × 4 Latin square design with 4 ruminally cannulated heifers.
Compared daily (1-D) versus every 3 days (3-D) feeding frequencies of forage harvested at hard dough and ripe stages.
Analyzed data using a mixed model of SAS after dietary adjustments.
Total dry matter intake (DMI) was not influenced by harvest maturity or feeding frequency (P ≥ 0.41).
Heifers fed 3-D had a lower average ruminal pH (5.53) compared to 1-D (5.89; P < 0.001).
Ruminal short-chain fatty acid concentration was lower on day 3 for 3-D fed heifers (P = 0.046), with no day differences for 1-D.
