I set a small group of cows up using protocol gnrh cidr for seven days on the seventh day pull cidr and shot of PG estrumate, and slapped a patch on them. I am at 36+ hrs and only have 2 cows ai'd. Is there anything I can do to bring the remaining 2 in. They are both 60 days post calving with body score of at least 5, mineral both had multi min shots 3 wks ago+ concept aid as loose mineral.
