I have a 20 month old jersey heiffer that has milk, pinkish sticky milk like colostrum. I noticed she had been making a bag for the past 3 weeks, so i thought she was just maturing, but nope she has milk, no calf! she might have been exposed last year because i had a 9 month old jersey bull in with her but he died last november...so if she would have been bred november would have been the last time she was with a bull...until this june (27th) I haven't ever really noticed her bulling, but the bull we put in there bred her on the 26th of july, she had been making a bag before he bred her, and she had long thick stringy mucus off and on for the last 3 weeks(before he bred her) with bright red stringy mucus blood stuff, like she is gonna have a calf...i check her about every 5 hours or so during the day (still mucus) and every 2-3 hours at night (still mucus) she looks a bit like she's springing, but i see her so much i can't tell a difference, i dunno i hate to have the vet come out to preg her, it costs so much...but why does she have milk, mucus, (and she is wanting scratched way too much these last few weeks) I thought maybe she had slipped a calf but i looked all over and she is only on 10 acres, and i watch her constantly, she has never walked around with an arched tail like she is getting ready, or slipped a calf...i don't know i'm gonna start calling her crazy katie! and can you feel a calf moving around like you cana horse? or maybe i'm feeling guts! any suggestions would be really helpful!
