[QUOTE="lithuanian farmer, post: 1555146, member: 19683"] We had pretty good luck with heifers last year. All on natural heats and have to call our vet to come for AI. 5 stuck on the first attempt,two even were bred at the same time, 2 on the second, one very likely had an early abortion as she was silent after the first try and came back in heat abit over 2 months later, and one was very hard to see in heat, so the first try was pretty blind on her with no activity seen, and she might have settled now after two more tries. Our heifers started getting meal after weaning and still gets some to improve their milk quality and quantity after calving. Most cows stuck on the first try (14-15). Haven't preg checked, so there might be some surprise, but they haven't showed any signs of repeat. The bull was running with them later, so either way they are incalf. Three cows needed 2 tries and three cows needed three attempts. Two cows haven't settled on AI no matter what but have settled with the bull on the first heat after letting him in. One more cow appeared to have a cyst, but now have AI'ed her and she seemed quiet. Managed to get incalf a 1st calf heifer, which was with the bull for two months and she still came back inheat. She might be the only one incalf with that AI bull, so even if she made some time off being not bred, but she might make up for that with her next calf. All in all, I think it was pretty good first year for me to observe heats for AI. Some tend to be inheat for longer and I see blood only 2 or even 3 days after the activity and AI and for some it takes only 1 day. [/QUOTE]
