This information seems to be pertinent to recent weather changes and the time of year. Heat stress affects ADG in an exponential manner.
Cold stress affects conversions in a linear manner.
Whether or not the animal is wet or dry is most important. The coldest month is usually also the wettest because of cold, wind, moisture. Black cattle absorb more heat than light colored cattle on sunny days, up to 20 degrees on the surface of the skin. Light weight and thin larger cattle are most often affected with increased death loss while we see the most weight loss in heavier cattle. Fluctuating temperatures have more to do with health than performance.
