I have a heifer due within the next week. I generally don't bring them down to the barn to calve until they start springing but busted her letting 2 other calves nurse yesterday & she's now in "prison" (at least I know she won't kick off her own calf). She definitely has bagged but not yet dialated, no mucus plug, no tail to the side. I have no idea if she let other calves nurse but it's unusual for a heifer's bag to be so full this early so I suspect that's the case. I always give newborns First Defense within the 1st 12 hours and if the calf is sluggish or I'm not sure how much colostrum it received I give it Nursemate ASAP. My question is, how many of you would go ahead & supplement her calf with colostrum replacer?
