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...]

Finding the $1,300 herdsire gap in the alphabet soup
Geneticist Murray Hunt, MS, has shaped many of the production measurements in dairy production.

Small ruminants are cool. Keep them that way. Especially during the fair.
Goats and sheep may be more heat-tolerant than cattle, but it’s still critical to reduce their exposure to heat stress as much as possible. It decreases dry matter intake, weight gain, milk production, body condition and overall performance. Temperature-humidity index, or THI, is the most accurate measure of animal heat stress in goats and sheep, which can be moderately … [Read more...]
