Troy Walz, Nebraska Extension Educator Photo credit Troy Walz. When some forages are frosted, the potential for bloat, toxicity, and nitrates may increase for grazing cattle. Bloat When grazing alfalfa in the fall, bloat remains a potential problem, especially during the first three to five days after alfalfa has been exposed to freezing temperatures. In general, the risk of bloat will be minimal only after a significant portion (about 50-70 percent) of the…
Jamie T. Parham, former UNL Graduate StudentRonald M. Lewis, UNL Professor Animal Breeding & Genomics Temperament in cattle is often evaluated using a common six-point chute scoring system. Temperament is an animal's behavioral response to handling by humans, or to any potentially fearful situation. Since these reactions are often linked with stress, they have negative effects on production and profitability. Because of its impact on pregnancy rates, growth, meat quality, and safety, producers…
