Introduction of greater number of beef-dairy calves entering US beef market continues to highlight the importance of pain mitigation during castration. However, no studies have compared pain responses to band castration between dairy and beef-dairy calves. This study aimed to evaluate pain mitigation and behavior in dairy and beef-dairy calves castrated with lidocaine-loaded or standard bands.
This blinded randomized controlled trial followed a 2x2 factorial design including breed (Holstein and beef-dairy) and band type (lidocaine-loaded and standard). Forty bull calves were randomly assigned to be castrated with lidocaine-loaded bands (HOL-LLB, n=9; BOD-LBB, n=9), or standard control band (HOL-CON, n=10; BOD-CON, n=10). Lie/stand behavior, gait analysis, plasma cortisol, and performance were analyzed in multiple timepoints. Linear-mixed effects models were used to determine potential associations between outcomes and band type, breed, time, and their interactions.
A significant breed effect was found for standing bouts, where they were more frequent in beef-dairy calves compared to Holsteins (18.3 and 17.3 bouts/day, respectively; SEM=0.49). Gait outcomes showed increased velocity and decreased gait distance over time for the CON group (P<0.05). Band type and breed had no effect on plasma cortisol and performance outcomes (P>0.05).
There was little difference in pain outcomes between beef-dairy and Holstein calves, suggesting that it is not necessary to provide different pain management between the breeds during band castration. Gait results indicate that the CON group may have experienced greater pain than the LLB group.
