Forage Sampling with a Brace and Bit
• Start sampling against the grain from the wrapped side of the bale
• Sample level or slightly elevated as you pierce the bale to insure sample doesn’t slide out of the probe
• Use wooden plunger to push the sample out of the probe into the sample bag
• Take a minimum of 10 to 15 samples per lot of hay
