Looking at Winter Supplementation as an Investment more than an Expense
October, 2023
Hannah Baker, UF/IFAS Beef and Forage Economist
There are several reasons for supplementing
during the fall and winter months on cow-calf operations. Forage quality and
quantity start to decline for most forage species as the growing season
comes to an end, but the nutritional requirements of cows who are expected
to calve during these same months are not declining. As a result of
compensating for the lack of nutrients from forages through starting
supplementation early, producers can maintain cows’ body condition scores
(BCS), improve pregnancy and calving rates, and increase weaning weights.
The health of your cows plays a major role in the health of their calves. If
all of mama cow’s nutritional needs are met, she can focus 100% on raising a
healthy, marketable calf. According to
“Implications of Cow
Body Score on Productivity (Matt Hersom, Todd Thrift, and Joel Yelich,
2018), cattle with a 5-6 BCS had higher pregnancy rates
and weaning weights than cattle with a BCS below 5. If her needs are not
met, she first must focus on surviving, with the needs of her calf being met
second, and being bred back is placed on the back burner. This results in
lighter weight calves at weaning and lower pregnancy rates, both of which
affect profitability. Therefore, it is important to know what your cows need
so that they can give you what you need: a stable and profitable income.
Knowing what your cows need starts with
knowing what they already have: forage. Sampling your forage/hay is the
important first step in calculating how much supplement to feed. Once you
know the protein and energy that is supplied through forage consumption, you
can then work with your nutritionist, feed rep, and/or Extension specialist
to know how much of a certain supplement you need for the fall and winter
months based on the stage your cows are in (gestation, lactation, dry,
etc.). For more information about forage sampling and south Florida forages,

Now that you know what your cows have and
what they need, you have a decision to make. Do you want to take a risk and
let your cows get by on just forage or do you want to invest in your cows so
that you can benefit from the return? Let’s create a scenario and pencil it
out!

supplementation plan and the economic benefits that follow.
With calf prices on the rise, invest in your cows now
so that they can raise and wean a larger and heavier calf crop in the
spring!
