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.
Buttercup, 2nd calf heifer (3/4 Jersey/1/4 Holstein) Cupcake (daughter of Buttercup) born 5-8-07 (7/8 Jersey/ 1/8 Holstein) BetsyRoss (daughter of Buttercup) b. 4/20/09 (7/8 Jersey 1/8 Holstein) 2 dogs - collie & English bull dog 7 cats Many old hens, young hens, too many roosters 9 guineas 5 Narragansett turkeys (Tom Hanks and his harem) 1 goat 2 geese Love them all
I had a 4 month old heifer come into heat recently . 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.

Basics needed to answer questions: age, weight, breed, sex, species. If health Q, take the temperature! Number affected vs number in group, feed type/amount, prior vaccinations, deworming, antibiotics, any recent changes....
More info = better answers.

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...
