Poor Temperament Adversely Affected Performance & Profit
Mississippi State Univ. researchers used a total of 210 feeder cattle consigned by 19 producers in a "Farm to Feedlot" program to evaluate the effect of temperament on performance, carcass characteristics, and net profit. Temperament was scored on a 1 to 5 scale (1=nonaggressive, docile 5=very aggressive, excitable). Three measurements were used: pen score, chute score, and exit velocity. Measurements were taken on the day of shipment to the feedlot. Following is a summary of results.
Exit velocity and pen scores were highly correlated. As pen scores increased, so did exit velocity.
Breed of sire had a significant effect on all three temperament measurements and on feedlot performance and carcass traits.
As pen score and exit velocity increased, treatments costs and number of days treated increased, while avg. daily gain and final body wt. decreased.
As pen score increased, net profit per head tended to decline:
1=$121.89
2=$100.98
3=$107.18
4=$83.75
5=$80.81
These results are in agreement with similar research conducted at Iowa State, Texas A & M, and elsewhere (Vann et al. 2006. ASAS Southern Section Mtg., Orlando, FL).
