Quando há pouco leite em um quarto, o que fazer?

NICO

Tenho alguns casos de vacas que, ao longo da lactação, um dos quarto mamário diminui o volume de leite produzido e começam a ter problemas em falhas na ordenha e condutividade elevada.

Quais estratégias podemos tomar?

    If one quarter starts giving less milk and conductivity goes up, that quarter is usually just acting up. Most of the time it’s either an infection brewing or it’s already had mastitis before and never fully recovered. First thing I’d do? Strip it out and just look at it. If the milk looks weird watery, flakes, clots you know what’s up. If it looks normal but conductivity stays high, it’s probably subclinical. That quarter might just be slowly dying off, especially if she had issues before. Also check:

    • Is the robot actually attaching well?

    • Is that teat getting milked out properly?

    • Any liner slip or vacuum weirdness?

    Sometimes it’s not even infection sometimes the teat end just gets damaged and that quarter never really performs again. Honestly, if she’s otherwise a good cow, eats well, breeds back, and the other three quarters are strong I wouldn’t panic. You’re basically running a 3.5-quarter cow. If she keeps failing milkings and being annoying… then yeah, maybe she moves down the list. It’s pretty common. Not ideal, but not dramatic either.

    Muito obrigado pela resposta,

    Lembrei-me de um fato com o que você falou: "por vezes, a ponta do teto simplesmente danifica-se e aquela divisão nunca mais produz leite adequadamente". Tivemos um problema com um produto que sela o teto das vacas após a secagem. Quando a vaca paria e íamos ordenhar, muitas tetos tinham se fechado (possivelmente este produto fez uma irritação dentro e, com o tempo, fez uma cicatrização dificultando ou até mesmo tampando). Vou rastrear estas vacas.

    Mas mesmo assim, acho que a outra quantia, se enquadra em um problema subclínico, que aos poucos está a morrer no quarto. Fazemos cultura dentro da propriedade e muitas destas dão negativa.  E no gráfico de condutividade ela sempre vem subindo gradualmente! como este caso da foto.

    Yeah I get what you’re saying.

    That dry-off seal story? That could definitely explain part of it. If the teat canal got irritated and formed scar tissue, that quarter is basically handicapped from the start. Once it calves in like that, you’re already behind. Tracking those cows is a smart move.

    But I also agree with you that doesn’t explain everything.

    That slow, steady rise in conductivity with negative cultures… that’s the frustrating kind. I’ve seen that too. It’s often not a “boom” infection, more like a quarter that’s just slowly giving up. Either old damage, mild chronic bug that doesn’t show well on culture, or it’s not milking out 100% and inflammation just keeps ticking up.
