It pays to test your livestock’s feedstuffs every year, but it is critical to test forages this fall due to extreme variation in quality of silage and hay produced during the drought of 2012. Iowa State University Extension agronomist Steve Barnhart and beef program specialist Joe Sellers said many producers have harvested silage from drought stressed corn, and proper ration development depends on knowing the nutrient content of that feed. Conservation Reserve Program (CRP) forage and cornstalk bales harvested this year also will be variable in quality, making forage analysis essential.
