Webinar summary: Setting the cow up for success – Transition management – Part 1
This webinar addresses key strategies and considerations for successfully managing dairy cows through the transition period, focusing on metabolic processes, cow condition, diet, and stress management.
In this webinar:
Overview of metabolic processes
- Transition impacts the rumen and liver significantly, with energy and nutrient dynamics critical for cow health.
- Effective management ensures cow recovery post-calving, improved milk yield, and overall health.
Essential factors for a successful transition
- Cow condition must average between 4.8 – 5.2 Body Condition Score (BCS) at calving.
- Diet calculations must consider energy, protein, and effective fibre (eNDF).
- Metabolic balance, particularly calcium, phosphorus, magnesium, DCAD, and trace minerals, supports optimal cow health.
- Ideal transition length is 21 days, though this can vary between 14 to 28 days based on dietary changes.
Cow condition management
- Proper cow condition ensures reserves, good appetite, and optimal metabolic balance.
- Over-conditioned cows face higher liver stress, poor recovery, and increased metabolic issues.
- Under-conditioned cows struggle with low production and variable appetite, needing careful energy allocation and protein management.
Diet formulation and calculation
- Accurate feed calculation based on cow condition and live weight is vital.
- Energy must be managed carefully to support rumen papillae growth without overstimulating the liver.
- Protein levels ideally should range between 16-18% to support metabolic demands, especially for at-risk groups.
- Fibre intake (ideally over 45%) is essential for rumen health, stimulating rumination, and reducing stress.
Metabolic balance and liver function
- Balanced minerals, especially calcium, magnesium, phosphorus, and DCAD, are key.
- Liver function benefits from specific amino acids, methyl donors, B vitamins, and trace minerals to enhance cow resilience.
Best feeding and supplementation practices
- Feed must be consistently and adequately allocated, prioritising essential nutrients first.
- Supplement blending and palatability significantly impact feed intake.
- Managing environmental factors such as feed accessibility and weather protection is crucial.
Reducing cow stress
- Minimising group changes, providing ample clean water, and ensuring ad-lib fibre availability are fundamental.
- Shelter from bad weather and gentle handling reduce stress, enhancing cow health and productivity outcomes.
