Dry-off deserves a bigger role in transition cow management
Dry-off is more than the end of one lactation; it is the first major biological event of the next one. Challenging the dairy industry’s long-held assumptions, Erminio Trevisi, MS, PhD, asserts dry-off transition deserves the same attention as calving because it marks the first stage of the next transition period. Trevisi’s research findings suggest dry-off does not reset the … [Read more...]
Bull fertility begins long before puberty
