Feedlot cattle with calm temperaments have higher average daily gains than cattle with excitable temperaments

This study was conducted to assess the effect of temperament on the average daily gains of feedlot cattle. Cattle (292 steers and 144 heifers) were transported to Colorado feedlot facilities. Breeds studied included Braford (n = 177), Simmental x Red Angus (n = 92), Red Brangus (n = 70), Simbrah (n...

Description
Summary:This study was conducted to assess the effect of temperament on the average daily gains of feedlot cattle. Cattle (292 steers and 144 heifers) were transported to Colorado feedlot facilities. Breeds studied included Braford (n = 177), Simmental x Red Angus (n = 92), Red Brangus (n = 70), Simbrah (n = 65), Angus (n = 18), and Tarentaise x Angus (n = 14). Cattle were temperament rated on a numerical scale (chute score) during routine weighing and processing. Data were separated into two groups based on breed, Brahman cross (greater than or equal to 25% Brahman) and nonBrahman breeding. Animals that had Brahman breeding had a higher mean temperament rating (3.45 +/- 0.09) or were more excitable than animals that had no Brahman influence (1.80 +/- 0.10); (P 0.001). These data also show that heifers have a higher mean temperament rating than steers (P 0.05). Temperament scores evaluated for each breed group also showed that increased temperament score resulted in decreased average daily gains (P 0.05). These data show that cattle that were quieter and calmer during handling had greater average daily gains than cattle that became agitated during routine handling
