(a) It is important that you get your milking machine checked by a qualified (MPTA) technician and have all faults corrected.
(b) Teat Spraying is a MAJOR part of mastitis control; many cows are infected just after milking is over. Research indicates an iodine teat spray for ALL seasons is best with about 15% emollient. This is especially when cows are on muddy paddocks, stand-off pads or herd homes.
(c) Treat and Record Clinical Cases:
(d) Cull Repeat Mastitis & Chronic High SCC:
(e) Dry Cow Therapy:
DCT is only part of mastitis control but it is vital.
Why use DCT? Research has clearly shown that cows undergo high levels of intramammary infection (IMI) in the first 2 weeks after Drying Off and then again in the 2 weeks just before they calve...so these are the times that they need most protection. NZ work shows that up to 50% of cows have not formed a teat plug by 7 days and 5% never form one. Every cow is challenged by infection whether she is a high or low SCC cow. In most of these cows this infection does not show as clinical mastitis in the dry period but then mastitis breaks out once they start producing milk at calving.
Either: WHOLE HERD therapy with or without Teatseal is the optimum way to protect cows during the dry period, as it helps cure high SCC cows and protects low SCC cows (in Canterbury herds it reduced mastitis by half).
Or: the next best is SELECTIVE therapy as in the SAMM Plan: treat all cows over 150,000 & heifers over 120,000.
Mastitis at calving:
