Now we have another good excuse to cull cows due to bad temperament.
Producers who routinely breed cows artificially realize that cows that are unruly and nervous are less likely to conceive to artificial insemination.
Presumably the lowered conception rates were because they have been stressed as they are passed through the working facilities and restrained while being synchronized and inseminated.
Now it seems that, even in the serenity of a natural breeding pasture, cows with bad dispositions are less likely to conceive when mated with bulls.
University of Florida animal scientists recorded disposition scores over two years on 160 Braford and 235 Brahman x British crossbred cows.
They wanted to evaluate the effects of cow temperament and energy status on the probability to become pregnant during a 90-day natural-breeding season.
Cows were scored as 1 equals calm, no movement, to 5 equals violent and continuous struggling while in the working chute.
Also a pen score assessment was assigned as 1 equals unalarmed and unexcited to, 5 equals very excited and aggressive toward technician.
An exit velocity speed score was measured as the cows exited the working chute as 1 equals slowest and 5 equals fastest.
An overall temperament index score was calculated by averaging the chute score, pen score and exit velocity score.
Blood samples were analyzed for cortisol concentrations. Cortisol is a hormone released when mammals are stressed or excited. Increased cow temperament score and elevated plasma cortisol concentrations both were associated with decreased probability of pregnancy.
These results suggest that excitable temperament and the consequent elevated cortisol concentrations are detrimental to reproductive function of cows.
These authors concluded that management strategies that improve cow disposition, enhance their immune status, and maintain the cow herd at adequate levels of nutrition, are required for optimal reproductive performance.

Can you believe such cool weather in mid July?
Refreshing. That’s the word one TV weatherman described the upcoming days when temperatures will be in the 70s with virtually no humidity and lots of sunshine. Can you believe that in the middle of July? We can live with that, can’t we? We may even get close to setting a record for morning lows later this week. This has certainly been the year for strange weather!
