Sophy is half Jersey, half black Angus, and is a bit over 8 months old (born June 19th). Today she was totally off the wall; mooing constantly whenever anyone came near the barn, being very clingy when I was in her stall cleaning it out, and she might have been thinking about trying to climb on me once or twice. Not sure about that last; I seem to have gotten pretty good at the body language for "don't you even think about climbing on me". She did the same thing a bit over a month ago. I don't seem to have written it down in the usual places, but I'm pretty sure it was January 20th, as I remember thinking she was almost exactly 7 months.
If it were one of our other cows, I'd be sure she was in heat, but I thought Sophy was still a month or three too young for that. I guess I should really put a tape on her and get some idea what she weighs, as everything I found around the internet says it's more a function of size than of age. But I thought I'd ask here as well.
I have seen them come in heat at 9 months before. Grew some heifers for a local dairy last yr that had 3 come in heat at 10 months and the dairy man had me go ahead and breed them . They all calved at 19 months
Joann has said that Jerseys tend to come into heat earlier than other dairy breeds. I can't remember the age she gave for them coming into their first heat though. From the behavior you mention it sounds like heat. Mark it down and check back in 21 days and see if she is "in the mood" again. When I bought Butter at one year, I was told that they had detected at least 2 heats so far.
I had a 4 month old heifer come into heat recently :o. I was horrified but watched as she mounted everyone in sight one day and then had a huge glob of mucous the next. I wouldn't think she would fall pregnant that early (she could have just walked out from under a bull ;D), but I'd never seen one that early before - mainly 6 to 8 months for our heifers.
When too many cows are barely enough
I've heard the beef guys talk about heifers cycling and settling as early as 2 months.... rare, yes, but it can happen. Heifers bred that early don't usually calve successfully.

OK, so 7 months isn't that unusual. Thanks. I was finding people saying that 9-10 months was usual for jerseys, and 11-12 for Angus, and Aster (all Jersey) didn't start cycling until a bit over 10, so I wasn't sure if that was what we were seeing with Sophy...

I know this thread is old but I found it very helpful. My Jersey heifer, Molly, is just 5 months and she has been moaning all day, looking longingly over the fence where the neighbor has an Angus herd and she has been trying to mount her mama.
I had no idea they could start cycling so early. Guess I'll start marking her times on the calendar. When her time comes I should be able to predict it pretty well. :-)
Janene and I learned that a 3.5 month old heifer calf can get bred and calve successfully. She learned it first when she came home to a healthy baby on the ground, then I learned it. It was a heifer too.

Last year my four month old BULL calves bred my yearling heifer. Now that was astonishing. None of the shorthorns begin to cycle before 13 months. And they live very long lives. I was curious why my guernsey/jersey cross hadnt begun to cycle at a year old, but she did as if on cue at 13 months. She will be bred in July at 15 months in two cycles. Jerseys are known to begin cycling early, and those maiden pregnancies can be dangerous. However, it's far safer to have an early gangly Channel Island calf (guernsey or jersey) than a beef or shorthorn because of their bulk.
Ivy started at 4.5 mos. So we've been living with THAT for a while now.
