FEED CHANGES: Farmers might want to consider feeding additional grain (protein and carbohydrates) and less of the fibrous portions of various plants.

Consider planting annuals to counter hay shortage

Ohio’s hay supply is the lowest since the 2012 drought, and the fourth-lowest in 70 years.

Ohio farmers are trying to keep their animals well-fed amid a Midwest shortage in hay and other grasses grown for livestock feed. According to Bill Weiss, dairy nutritionist with Ohio State University College of Food, Agricultural and Environmental Sciences (CFAES), that means livestock diets will need to change.

“They [farmers] have to start cutting back right now,” says Weiss.

Cutting back doesn’t mean the animals will have to eat less; it means they might need to eat more alternatives to the higher amounts of fiber they typically get.

For example, if hay, which is high in fiber, normally makes up about half the diet for a dairy cow or other animal, cottonseed could substitute for some of that hay, Weiss says. Cottonseed is what’s left of a cotton plant once the cotton fibers are removed.

Farmers might also feed their livestock additional grain (protein and carbohydrates) and less of the fibrous portions of various plants. “It’s what we have to do,” he says.

Before making any changes in what their animals are fed, livestock owners should consult with a nutritionist, Weiss advises.

While humans can live reasonably well without much fiber, cattle cannot. They need it. About one-third of their diet should be fiber, which provides them energy and keeps their digestive systems healthy.

Many farmers across Ohio are considering different diet options for their livestock because the state’s hay supply is the lowest since the 2012 drought, and the fourth-lowest in 70 years. The persistent spring rain during Ohio’s wettest yearlong period on record did not allow much hay to be cut in time for it to be of the highest quality.

Dairy cows are particularly affected. Most dairy farmers feed their cows large amounts of corn silage. But the wet spring has delayed or prevented the planting of corn, a key ingredient in a lot of livestock feed. So, with fewer corn acres expected to be planted and an already-low supply of hay, farmers are scrambling to plant other crops to feed their animals, such as cool-season grasses, including oats and cereal rye.

“Timing is critical here,” Weiss says.

Annual grass options

Some of the options being considered for animal feed are grasses such as sorghum and sorghum-sudangrass, and other warm-season summer annuals. If planted soon, they can be harvested from September through early October and then fed to animals.

“These feed options are not as nutritious as conventional ones,” Weiss says. “But we can make them work.”

Farmers wanting to plant summer annuals to feed their livestock need to do so now to have enough of a warm growing season to grow and be able to harvest before frost arrives, says Mark Sulc, a CFAES forage specialist.

Other cool-season crops can be planted a little later, starting the last week of this month and into August, Sulc says. These include oats and spring triticale, which will be ready for harvest starting in early October and into November. Oats and spring triticale can also be planted in mixtures with cereal rye, which has the advantage of being able to survive the winter, and it’s able to produce animal feed early next spring.

Since many farmers will be planting these annual crops for the first time this year, it’s critical for growers to know the requirements for each type to produce sizeable yields, Sulc advises.

The flurry of planting annual crops for livestock feed, “will help the shortage, but it’s not going to solve it completely,” Sulc says. “We can’t grow enough this year to supply the entire demand. That’s why we need to consider alternative fiber sources.”
