winter stockpile for dairy

In answer to questions about winter stockpile:

‘Stockpiled forage’ means mature plants left standing in the pasture and reserved for use after the growing season.  Note that we say ‘mature’ plants, not senescent or lignous.  We time our summer grazing to leave half the pasture acres untouched after their mid-summer grazing.  For this part of Ohio (east central, zone 6), that means that somewhere around the middle of July, or a bit later, whatever we graze over the next six to eight weeks is going to be taken out of the rotation for the rest of the growing year.  About half the farm will be grazed over this lste-summer period.  Then in Sept/Oct/Nov we graze the other half, leaving the earlier pastures to regrow.  We’ll probably make two rotations on the part we’re not stockpiling, depending on what the weather is doing.  In a perfect year — 2018 was pretty satisfactory — we’ll get some good rains and lots of regrowth, and the stockpiled pastures will be fully mature when the cold weather sets in.  Then come late November/early December we finish grazing the fall pastures and start around on the stockpile.

It probably goes without saying that we’ve stockpiled the pastures where we have the most frost-free water (spring-fed tanks).  We don’t like permanent lanes and the impact they get, but in the winter when there’s no snow on the ground we have to leave a temporary lane open back to water.  We use reels to build the lanes, and move them often to minimize the opportunity for back grazing.  Some of the bunch grasses (especially orchard grass) are going to be hit too hard if the cows get bored and start lounging back toward water, so we watch for this and shift the lane fence accordingly.  This method works well for us, and the improvement we’ve seen in our pasture composition and productivity over the last six years has been very satisfactory.
