Developing and validating measures of temperament in livestock
Temperament and calf serum protein influence weaning weight in Brahman cattle. Additionally, over the past several years real-time ultrasound has provided a means in which to measure carcass traits. Researchers have determined that feedlot cattle with calmer temperaments have higher average daily gains than cattle with excitable temperaments. Effect of feeding method and temperament on measures of feed efficiency and age of puberty in Brahman bulls. Temperamental cattle have higher levels of cortisol stress hormone indicator throughout their lifetime than calmer cattle.
The temperament traits that have received most attention are generally those that have adverse production, welfare or human safety consequences. This measure can then be used in a number of ways.
In addition, temperament was predictive of response to transportation. Temperament score was an average of exit velocity and pen score. Target audience is beef cattle producers, breed associations, national, state and local cattleman's associations, farm bureau and any other agriculture commodity groups with interest in beef cattle. Steers, bulls and heifers representing several genotypes from experiment stations in Mississippi and one station in Texas will be used in these studies. No Project Modifications information reported.
Sexually dimorphic secretion of cortisol but not catecholamines in response to an endotoxin challenge in beef calves. Relationship of temperament and growth in the suckling beef calf. Utilizing a combined temperament score which is the average of pen score and exit velocity provides a better assessment of temperment than chute score alone. This section will investigate the progress with regards to trait definition and measurement.
Evolution of exit velocity in the suckling Brahman calf. Furthermore, individuals are often consistent in the way they respond when the challenge is repeated. The two following specific aims further detail the objectives. Minimal changes in rump fat occurred during this study. Use of neonatal blood parameters to predict weaning weight in Brahman cattle.
Influence of bovine temperament, transportation, and lipopolysaccharide challenge on ultrasound body composition traits. Relationships of cortisol and immunoglobulin G concentrations to temperament and growth performance in beef calves. Relationships between cattle temperament and future growth performance in beef cattle.
Effect of temperament on passive immunity, cortisol concentrations, and early growth in the calf. Temporal effects on bovine neutrophil function following an intravenous endotoxin challenge. Temperament was predictive of rectal temperature changes due to transport.
Santos, Mississippi State University, K. However, temperament was a clear indicator of the response of bulls to transportation. Temperamental bulls had greater concentrations or cortisol and epinephrine and also had greater body temperature when compared with calm bulls. The influence of bovine temperament on rectal temperature and stress hormones in response to transportation.
