Summary
This field trial investigates the effects of contrasting rearing strategies on dry matter intake in pasture-based dairy heifers, a foundational metric for understanding heifer development and future lactation potential. The research appears to compare management approaches within grazing systems, contributing to evidence on optimising feed intake and growth trajectories in pasture-dependent dairy production. Findings may inform decisions on supplementation timing, housing protocols, or grazing management during the rearing phase.
Regional applicability
Given the Irish authorship and pasture-based focus, findings are likely highly applicable to UK dairy systems, particularly in regions with grass-based or mixed grazing protocols. Results may support evidence-based decisions on heifer rearing practices compatible with organic or low-input UK dairy farms.
Key measures
Dry matter intake (DMI), likely alongside growth performance metrics, feed conversion efficiency, and pasture utilisation measures
Outcomes reported
The study examined how different rearing strategies (likely varying pasture management, supplementation, or housing approaches) affect dry matter intake in dairy heifers managed on pasture-based systems. Dry matter intake is a key performance indicator linked to growth rates and subsequent dairy productivity.
