What the Study Evaluated

A study published in Journal of dairy science in 2026 evaluated randomized field trial on the effects of on-arrival intranasal vaccination against bovine coronavirus on pneumonia and average daily gain in beef-on-dairy calves..

Key Findings

This randomized clinical trial evaluated the effect of upon-arrival intranasal vaccination against bovine coronavirus (BCoV) on pneumonia risk in a beef-on-dairy veal production system. Secondary objectives were to assess the effect vaccination on lung ultrasonographic cure, clinical bovine respiratory disease (BRD), average daily gain (ADG) and cold carcass weight (CCW). Be…
