    Tips for Winter Grazing

    February 4, 2019

    Characteristics of a good grazing hybrid:

    • Early silage hybrids are the best option for winter grazing.
    • Choose hybrids that will reach 50% milk at first killing frost. 
    • Select hybrids that produce high forage yields and high digestibility.
    • Choose hybrids with known standability. 
    Paddock management 
    • Use a high-quality electric fence to partition off your corn field.
    • In the beginning, slowly introduce your herd to corn.
    • Limit exposure and supplement with hay until the cows start to become comfortable.
    • Limit cows to three or four days of feed at a time. This limits their ability to overindulge on cobs and ensures they clean up the stalks. It also minimizes the risk of potentially life-threatening rumen acidosis
    • Clear alleyways for your fence. This allows the cattle to move through the paddock in the initial turnout.
    • Having a shelter for the herd is ideal; it can be bush or a portable windbreaker shelter.
    • Access to soft fresh snow or a viable water source is a MUST.

    Agronomy tips
    • Take whole plant samples to ensure you know what nutrients your cows are getting.
    • Watch for signs of grain overload during years of full cob development as cows eat the cobs first and come back for stalks afterwards.
    • Wait for the cattle to clean up stalks before moving them to the next paddock.
    • Wait until ground is firm/frozen as this will minimize the loss of feed that is trampled and lost in the mud.
    • Always have a supply of back-up feed. Heavy snow or extreme cold and bad weather can add challenges to the cattle grazing.
    • Plant two or three different hybrids spread over your maturity range. This allows for you to spread out your maturity and acres for a given area.

    Why winter grazing is a win, win
    • No need to start your tractor in harsh cold conditions.
    • No manure management; it’s already in the field.
    • Winter grazing can provide beef cattle with a high-quality nutrient source into mid and late stages of pregnancy.
    • Minimal summer feed harvesting is needed.

    Acres of corn needed
    • Plan for 200 cow days per acre of corn.
    • Acres required for 200 cows for 30 days of grazing:
    • 200 cows X 30 days = 6,000 cow grazing days required.
    • 6,000 cow grazing days / 200 cow days per acre = 30 acres corn.
    • Insert your own numbers for your specific farm needs.
