DairyTalk 700: Longevity Needs Age-Specific Management: Why Health Risks Change with Every Lactation - by Helmut Demmelhuber

Fertility and lameness risk were broadly similar between systems, while mastitis occurred more frequently among housed cows. This shifts attention toward how health risks evolve as cows progress through successive lactations rather than treating every age group as biologically equivalent. The…
