Partners Networking to Advance South Island Dairying

West Coast Monitor Farm

Westland has some unique challenges such as high rainfall and seasonal dry peroids which are variable across the region. Westland has now been collecting data for 10 years and continues to building on the information currently available.

This project funded by Westland Milk Products, DairyNZ, CRV Ambreed, ARL-Ravensdown and Rabobank aims to generate reliable pasture growth and quality, and soil temperature information, over the next 12 months, on two commercial dairy farms in Westland.

Farm walks schedule for this season are weekly from August to May, and monthly over the winter period.

Each week we will provide a Weekly Summary of information from the following regions:

Buller: Mawheraiti (Stu and Deb Bland), Westland: Kowhitirangi (Anna and Jeremy Hart).

Expanded farm summary for the week ending 14 August 2019

CO comment

 

Most cases of environmental mastitis occur within a few weeks of calving, when the cows’ natural defence mechanisms are low and their teats have been in contact with mud and manure during calving.

Exposure of teat ends to environmental bacteria can occur at any time though: before and during calving, at milking time or in paddocks during the lactation or dry periods. During lactation, factors that predispose cows to infection with environmental bacteria include milking udders that are wet or dirty, or administering an intramammary infusion if the teat orifice is not sterile

Remember Streptococcus uberis is the most common cause of environmental mastitis in New Zealand. Streptococcus uberis usually responds to treatment with bacteriological cure rates of the order of 80% reported.

Severity of clinical signs may vary from slightly abnormal milk to severe swelling of the udder and an elevated temperature. Severity can increase when treatment is delayed.

Strep. uberis infections, if undiagnosed, can contribute significantly to bulk milk contamination.

Reduce exposure to environmental mastitis bacteria by …

Calving on clean, dry pasture or a clean, dry calving pad

Monitor the number of cases of mastitis occurring, especially in recently calved heifers

Bring cows into the dairy as soon as possible to be checked for mastitis and milked

Take special care with high risk cows

Take care with pre-milking preparation of udders
