5 Tips for Beef Cow Herd Winter Supplementation

With first blast of winter weather quickly approaching, have you thought about what that means to your cow herd? Keeping cattle in good condition through the fall and into early winter ultimately helps insulate the animal and minimize the amount of feed required later in the winter season.

Kevin Glaubius, Director of Nutrition and Technical Sales at BioZyme® Inc., says now is the time to take an honest evaluation of body condition and match your feeding program to the needs of your cows. St. Joseph, MO-based BioZyme manufactures vitamin and mineral supplements for a variety of livestock.

“The bottom line is, early cold stress can result in a snowball effect if left unchecked. Cold temperatures significantly raise energy requirements. Undeveloped winter hair coats, wet hides and wind all combine to magnify this increase in energy requirements,” said Glaubius. “The combination of calving cows and colder environmental conditions can easily result in producers not providing enough feed energy and cows losing weight.”

So what can producers do to manage the cold stress and feed adequately during the winter months? Glaubius offers some tips:

1. Feed higher quality hay (with more energy) and expect cows to increase intake. Without a forage analysis, you cannot be exactly sure of your hay’s energy level, which can lead to inadequate nutrition. BioZyme offers complimentary hay testing and nutrition analysis to producers through its nationwide dealer network and Area Sales Managers.

2. Feed cattle a supplement that contains BioZyme’s Amaferm® to improve digestibility of feed and helps ensure that they are extracting all of the energy possible. Research shows that feeding a supplement that contains Amaferm has similar benefits to feeding at least 1lb. of grain.
3. Consider moving cows to locations with protection from the wind and wet weather. The energy requirement of beef cattle increases about 3% for each degree that the wind chill is below 59 degrees F.  This increases even further in wet conditions and prior to fully developing a winter hair coat.
4. Match animal nutrition requirements to the quality of your forage. Heifers and thin cows require a more energy-dense diet, compared to older or fleshy cows. Sorting animals into groups based on body condition allows you to feed the available forage more effectively. Start by targeting your higher quality, more immature forages toward heifers and thin cows. These earlier harvested forages will be the most energy dense as energy declines considerably with maturity. The older and higher body condition cows can then be fed slightly more mature forage. This allows you to maximize the use of your forage supply while better targeting the nutritional needs of your entire herd.
5. A good guideline is to feed 3-6 lbs. of energy supplements like soy hulls, corn gluten feed, or corn to avoid weight loss during these stressful periods.

A strong nutrition program is key to maximizing the performance of your cow herd. For more information about winter supplementation, contact Kevin Glaubius at 816-344-5762 or kglaubius@biozymeinc.com.
