Another challenging year for spring moisture has created a deficit in hay production across much of the Dakotas and Minnesota, leaving ranchers to consider options to increase their forage supply. Lack of rainfall from mid-May to mid-June impacted forage production of perennial grass hay fields such as brome grass, crested wheatgrass, timothy and orchardgrass. State-wide reports have indicated as much as a 40% decline in hay production compared to the previous year.
“Recent precipitation may make annual forages and cover crops viable forage options for hay production or grazing,” says Miranda Meehan, North Dakota State University Extension livestock environmental stewardship specialist.
Despite recent rains, available soil moisture and recommended planting dates will limit options. Forage species selected will vary based on primary planned use: hay, fall grazing, or next spring haying or grazing.
Recommended forage species for hay production “The best options this late in the growing season will be warm-season forages,” says Kevin Sedivec, NDSU Extension rangeland management specialist. “Foxtail millets have the shortest growing period (seed germination to heading). With droughty conditions, Siberian millet may be the best option; however, under better moisture conditions, German millet could be a better option to maximize production potential. Other options include sudangrass and sorghum-sudangrass hybrids.”
These warm-season crops should be planted by no later than late July or early August. Harvest before a hard frost or directly following the hard frost to retain forage quality and palatability. Sudangrass and the sorghum-sudangrass hybrids have higher yield potential, but because of the shorter day-length and cooler temperatures in late summer and early fall, sufficient dry down to put up hay can be difficult when using a sorghum-sudangrass hybrid. A dry stalk trait is available in some sorghum-sudangrass hybrids that speeds drying time due to stalks containing a lower moisture content.
Recommendation for fall/winter grazing Many forage options can be planted now and grazed late summer through early winter. Foxtail millet, sudangrass and sorghum-sudangrass can also be used as pasture. However, once they freeze, livestock tend to be more selective and increase waste through trampling. Following a killing freeze, allow sorghum species to completely dry down before grazing to minimize prussic acid potential.
Cool-season cover crop mixtures make excellent pasture well into the early winter period. However, cool-season plants are less efficient at using water and will be more prone to fail if dry conditions persist. Make sure ample topsoil moisture is available for plant establishment.
A good option for a fall and winter grazing mix is a seed mixture with a combination of cool and warm-season crops. The cool-season crops will retain nutritional quality after a freeze while the warm-season crop provides fiber for energy and proper rumen function. Cool-season cover crop options may include a mixture of oats, barley, turnips or radish.
