ALTERNATIVE APPROACHES TO HELMINTH MANAGEMENT.

Discipline: infection; Key words: helminths, anthelmintic resistance, phytotherapy, bioactive forages, vaccines, grazing management.



An elicitation exercise was conducted to collect and identify pressing questions concerning the study of helminths in livestock, to help guide research priorities. The authors cited below are the primary global experts who compiled the report. Whereas this presentation does not cover research results as usual, I consider it important to share their ideas with the reader as a main focus of our R & D is in control of parasites and because prominent researchers in the group are South African or South African of origin.
AN INVESTIGATION INTO TAKE-OFF TIME IN MILKING MACHINES.

Discipline: mastitis; Key words: teat canal, udder health, milking machine settings, milk flow, VaDia, take-off time, vented liners.
