Utilize Corn Stalks for Grazing

 

 

Corn residue can serve many purposes on cow/calf operations in the Upper Midwest. From grazing to bedding; however, it may be one of the most underutilized resources we can access to produce beef. This year’s harvest is in full swing and yields are looking great; therefore, residue should be plentiful as we enter into the winter grazing period.

 

Producers looking for ways to decrease feed costs in the winter time should utilize corn stalks as a grazing resource for mid-gestation cows. The combination of dropped ears, grain, husks and leaves, provide an adequate ration for spring calving cows, and can be managed to maintain body condition or even add weight with supplementation. The amount of residue per acre is correlated to pounds of grain produced. However, the most palatable portion of residue (husks and leaves) makes up approximately 15 pounds of every bushel of corn. So if a field yields 150 bushels per acre, there would be 2,250 pounds of husks and leaves available for grazing. Similar to pasture, grazing recommendations of take half, leave half still stand. Therefore, after trampling, wind and waste disappearance, etc., there would be enough residue remaining on one acre to support a 1300 pound cow for a little more 30 days.

 

Managing residue grazing should always start with a walk through the field to identify any spills or large amounts of grain that need to be removed prior to grazing in order to decrease risk of acidosis. In addition, fences need be examined and water resources located to facilitate grazing from November to January and even longer if snowfall is limited over the winter. Cross fencing can be utilized to facilitate strip grazing which will provide a more balanced ration for cattle over the winter. If residue is not sectioned off, quality of the ration will decrease over the winter. Cattle will seek out corn first, then go to husks, leaves and then less digestible cobs and stalks. As the grain disappears, supplement cattle with a protein source to maintain proper rumen function and avoid decreased performance. Lastly, always provide mineral and salt to cattle while grazing stalks.

 

Grazing corn stalk residue can reduce both feed cost for cow/calf producers, but also save crop farmers time and money by decreasing time spent running equipment over the field to remove excess residue. If communication between cattle and crop operations is needed to set up a grazing agreement, start by asking and answering the following questions:

Video: Why Invest in Canada’s Seed Future? | On The Brink: Episode 3

Darcy Unger just invested millions to build a brand-new seed plant on his farm in Stonewall, Manitoba so when it’s time for his sons to take over, they have the tools they need to succeed.

Right now, 95% of the genetics they’ll be growing come from Canadian plant breeders.

That number matters.

When fusarium hit Western Canada in the late 90s, it was Canadian breeders who responded, because they understood Canadian conditions. That ability to react quickly to what’s happening on Canadian farms is exactly what’s at risk when breeding programs lose funding.

For farmers like Darcy, who have made generational investments based on the assumption that better genetics will keep coming, the stakes are direct and personal.

We’re on the brink of decisions that will shape our agricultural future for not only our generation, but also the ones to come.

What direction will we choose?

On The Brink is a year-long video series traveling across Canada to meet the researchers, breeders, farmers, seed companies, and policymakers shaping the future of Canadian plant breeding. Each week, a new story. Each story, a piece of the bigger picture.

Episode 3 is above. Follow Seed World Canada to catch every episode, and tell us: Do you think the next generation will have the tools they need to success when they takeover? How is the future going to look?
