Description
Upulika Jayaneththi and co-authors follow the gut microbes of cattle and sheep across years on a working New Zealand farm, in a 2026 study. The microbes govern how well farm animals turn feed into growth, yet most studies run short and tightly controlled. The team compared four setups crossing two pasture types, standard and diverse, with two management styles, current practice and regenerative.
From 2022 to 2025 they read microbe DNA from dung samples. Overall make-up stayed broadly steady, with clear swings by season. One genus led in both hosts but vanished from one cattle group in a winter month, when another took over. Diversity held steady in most groups, yet it dipped sharply that same winter under current management, while the diverse, regenerative pastures kept it higher in cattle. The authors weigh season as a force in its own right.
