In the fourth of Beef + Lamb New Zealand’s ‘Parasite Chronicles’ podcasts, Sarah Perriam-Lampp talks with Dave McKenzie about how and why he is reducing drench inputs in his farm system. Dave farms sheep and beef on Montrose Estate, North Canterbury and was part of a B+LNZ Research funded study, carried out by Massey University, to understand how and why farmers are already farming with less drench.
