The seasonality of gastrointestinal nematode species abundance (excluding Nematodirus) in sheep of different classes across New Zealand

New Zealand Journal of Agricultural Research, Volume 68, Issue 7, Page 2436-2455, December 2025.
ABSTRACT A survey on nine farms across New Zealand assessed the seasonality and species composition of gastrointestinal nematodes in three sheep classes: lambs (<1 year), 2‐tooth ewes (1–2 years), and mixed age ewes (>2 years). Monthly faecal samples from each class underwent faecal egg counting and deep amplicon sequencing of cultured third‐stage ...
