Low-Stress Handling Improves Bottom Line

“People can enhance the genetics in these animals, but we can have caregiver impact that actually takes away from that potential,” said Noffsinger. He spoke at a Feeding Quality Forum in Grand Island, NE and Amarillo, TX. Noffsinger said animal handling affects many determinants of profitability, along with employee morale and safety. “Our goal at a feedyard or
ranch is to empower caregivers to be dedicated and make every human-to-cattle interaction a positive one,” he said. “When we have dealt with issues in caregiver training, all of a sudden turnover at most of my (consulting) feedyards is zero.” He explained how to use natural animal behavior to improve weaning, sorting and processing.
Understanding and avoiding heat stress in cattle can be a valuable management tool for summertime. Many cow/calf operations have to work cattle on days when heat stress to cattle is possible, says Glenn Selk, Oklahoma State University Extension cattle reproduction specialist. Cattle have an upper critical
temperature approximately 20 degrees cooler than humans. When humans are uncomfortable at 80 degrees and feel hot at 90 degrees, cattle may well be in the danger zone for extreme heat stress, he says in a news release. Humidity is an additional stressor that intensifies the heat by making body heat dissipation more difficult.
Over heating is sporadically encountered in cattle, but is really a rare problem. High humidity contributes to the likelihood of heat stroke or prostration because water evaporation from the oral and nasal cavities is decreased in spite of rapid panting. At an environmental temperature of about 88 degrees, heat dissipation mechanisms, such as sweating and evaporative cooling must take place to prevent a rise in body temperature. Sweat gland activity in cattle increases as the temperature goes above the thermoneutral zone. Panting is an important heat regulatory device in cattle. The signs of overheating may develop suddenly and depend upon the environmental conditions and the health of the cattle exposed to the heat. Panting often

Cattlemen often analyze practices based on the return on investment (ROI) but usually they’re only talking about money. Tom Noffsinger, veterinarian and low-stress handling specialist from Benkelman, Nebraska with 37 years of experience in the industry, says working cattle can prove an old equation: investing a little more time than can have significant payoffs down the road.
