heat cycles?

[branxchar&charx]

how long is it between a heifer's heat cycles?
i gave her a shot a few days ago of lutalyse (guess spelled right)(thought she might have been bred)
she showed signs of being in heat yesterday (discharge, rockin back & forth, etc...)
also how long are they in? the shot messed up her cycles right?

The shot will cause her to cycle within 2-4 days of getting it. She will then go back to cycling every 17-21 days whatever is normal for her.
