If you are thinking its OK to feed that "feed hay" to your livestock without checking its nitrate content because this was such a moist year, think again, said OSU Extension Educator, Dana Bay.
According to Bay, extension experts have been getting samples of feed grasses in for testing that have reached higher than 5,000 ppm nitrates, high enough to possibly cause mid to late-term abortions and weak newborn calves. It may also decrease growth and milk production, according to Bay,
"Way too many samples have tested over 10,000 ppm," Bay said.
Bay is referring to feed hays such as Sorghum, sudan grass, sorgo-sudan grass, sudan-sudan, and pearl millet.
That level of nitrates is potentially toxic to all cattle, she noted.
"If you have put up feed hay this year or purchased feed hay and have not had it tested, I strongly encourage you to do so before feeding any of the hay to your cattle."
