Abstract
Colostrum, housing hygiene, and early nutrition — the quiet determinants of adult performance.
The most expensive genetics can be undermined by poor calfhood. Immunity, frame development, and temperament begin in the first weeks of life.
§01Colostrum
“Timing, quality, and volume of first feeding shape passive immunity.”
Timing, quality, and volume of first feeding shape passive immunity. Measuring colostrum quality should be routine, not optional.
§03Environment
Dry bedding, clean air, and low stress handling reduce disease pressure more effectively than reactive treatment alone.
§04Records
Birth weights, daily gains, health events, and parentage must enter the same data culture as adult milk and genomic scores.
