1. Mastitis Program:



1.1. PRJ-0210 Antimicrobial resistance on dairy farms - Screening mastitis causing coliforms for the production of extended spectrum Beta-lactamases and Colistin resistance. Dr Inge-Marie Petzer.
WATER NEEDS OF PASTURES USED IN DAIRY PRODUCTION.

Discipline: forages/grazing; Keywords: pasture management, water requirements, irrigation guidelines, subtropical pastures, grass/legume mixtures.
MANAGEMENT PROTOCOL OF MASTITIS ON SA DAIRY FARMS.

Discipline: mastitis; Key words: diversity, management practices, antibiotics, pre-dip, strip, bulk milk somatic cell count, AMR. 



The South African dairy industry shows immense diversity when it comes to mastitis management practices. However, if consistently executed, which should improve udder health and milk flow, it could be satisfactory, but supporting the diversity by extension is a challenge. As is the case globally, the dairy industry is aware of and actively addressing antimicrobial resistance (AMR). To that effect, a survey was funded by Milk SA to record what practices are followed and a project: ‘Resistance to Available Antibiotics in Lactating Cows with Mastitis’, was initiated in 2015. The results of the survey were published by the authors cited below.
