Had a cow separate from the herd. Went out to look at her and see if i could tell what her problem was. She had 5 vultures sitting around her. She was not breathing heavy, her ears were up, no loose poop behind her, moved fine. Nowhere near death to summon buzzards, so that was werid.... After seeing me over where she was, it is where we are feeding hay, the herd came thinking i had some cubes for them.. What i observed was, as they got to this cow, they all smelled of her. Some licked her. She had a swarm of cows doing this. I thought, hum..(no mounting like she's in heat). So later that day we get her up, separate her from the herd.. Put her in the pen with the heifers, where, they do the exact same thing. Licking, sniffing, huddled around her. The only thing i could figure was wrong was maybe some UTI, she did pee several times and not a lot each time. Could a UTI give her a smell? Thats what we treated her for.
