Bitch I bred mismated day 10, had Alizin injections days 13 and 14. Still flagging like MAD on day 26. The datasheet says nothing about prolonging seasons, but has anyone here got experience of that happening or heard of it? If so how long did it go on for?

Mis mate jabs can prolong the season by 2 weeks, don't know if that applies to alizin in particular.
