Cow Ketosis Prevention: Transition Cow Nutrition

Preventing ketosis through evidence-based transition cow nutrition is one of the highest-impact welfare and productivity interventions available in dairy farming.

Key Facts

Ketosis peaks in the first 2-3 weeks after calving when energy demands are highest and intake lowest
Overconditioned cows (body condition score over 3.5 at calving) have higher ketosis risk from excessive fat mobilization
Far-off dry cow diets should be relatively low-energy to prevent overcondition entering the transition period
Close-up diets (last 3 weeks pre-calving) containing propylene glycol or glucogenic precursors reduce ketosis risk
Rumen-protected choline is one of the best-evidenced nutritional interventions for reducing transition disease risk
Fresh cow monitoring programs using on-farm ketone testing within 2 weeks of calving identify subclinical cases
Early identification and treatment of ketosis before clinical signs develop produces much better outcomes

Welfare Considerations

Ketosis prevention welfare operates on the principle that preventing disease is more welfare-positive than treating it well. A cow that enters the transition period in good condition, receives evidence-based close-up nutrition, and is monitored proactively for ketosis has dramatically lower probability of experiencing the cascade of metabolic and infectious diseases that follows poorly managed transition. The welfare of the fresh cow is directly shaped by what happened to the dry cow weeks before. Investment in transition cow management is investment in reducing suffering - the economics align with the welfare motivation because ketosis and associated diseases significantly reduce production as well as welfare.

What You Can Do

Support dairy farms with documented transition cow monitoring programs using ketone testing
Choose dairy products from farms with low disease prevalence data including ketosis rates
Advocate for welfare standards that require transition cow health monitoring
Support agricultural extension services helping conventional farms implement evidence-based transition nutrition
Engage with dairy companies about requiring transition cow health data from their suppliers
Reduce dairy consumption from farms without documented health management programs
