Mother Nature is taking the gloves off this week, delivering another one-two punch of Arctic cold and precipitation.
"Cattle are generally fine in the cold weather," said Shane Gadberry, associate professor for the University of Arkansas System Division of Agriculture. "However, when the weather turns wet, the situation changes."
Gadberry recommends that ranchers:
- Provide shelter. "Cows with a normal winter coat cope well with temperatures as low as 32 degrees and much lower for breeds that grow a heavy hair coat," he said. "However, a wet coat increases a cow’s lower critical temperature to near 60 degrees." The wind chill factor is important as well. "Cattle producers aren’t set up to keep cattle from getting wet during winter, however, windbreaks which reduce wind chills are beneficial. Move cattle where they can easily access natural or manmade windbreaks," Gadberry said.
- Feed higher quality hay. When it’s cold, cattle need more calories to keep warm. Hay that’s high in protein and total digestible nutrients will provide more energy to cows. Gadberry said that during winter, a cow’s food intake can increase 5 to 10 percent. "Make sure cows have free choice access to hay," he said. "For personal safety, put out several days worth of hay to minimize the amount of travel on icy roadways, and account for higher intakes when estimating how much hay to make available."
- Keep water available. Water intake and feed intake are related. If cattle can’t drink, this will affect their food intake and ability to cope with winter weather.
- Watch for mud after the thaw. Muddy conditions can affect food intake. When mud is widespread and thick around feeding stations, "food intake can be reduced by as much as 15 to 30 percent," Gadberry said. Make sure feeding sites are well drained, watch cattle feeding behavior to determine the difficulty in accessing the hay ring or feed bunk, and relocate feeding areas if mud becomes an issue.
