Temperament Affects Performance
Darrell Busby, Iowa Beef Extension Specialist, SW Iowa recently reported on data collected on cattle fed in their Tri-County Steer Carcass Futurity. A summary of his data is presented below.
Compared to docile cattle, aggressive cattle:
· Gained 8.2% less in the feedlot
· Used feed 1.8% less efficiently
· Had 20% fewer Choice or higher carcasses
· Had 115% more Standard carcasses
· Had 51% fewer CAB carcasses
· Showed a decreased profit of $62.19/head
Disposition score by breed

Hereford 1.3
Simmental, Red Angus, Angus 1.6
Gelbvieh 1.7
Charolais 1.8
Limosin 1.9
Brangus 2.2
Disposition score 1=docile, 2=restless, 3=nervous
Effect of using a hot shot on performance and disposition score
Day 1no hot shot Day 2no hot shot Day 1no hotshot Day 2use of hot shot
Processing time, sec/hd 42.8 36.9 (-9.3) 43.8 36.9 (-6.9)
Disposition score 2.01 1.84(-0.17) 1.62 2.20(+0.58)
Disposition score 1=docile, 2=restless, 3=nervous
Conclusion:
- Hot shots increased disposition score without decreasing processing time.
- Breed has less effect on disposition than does management.
