Frequently Asked Questions

Why is colostrum vital for newborn calves?
Calves are born agammaglobulinemic with zero maternal antibodies. Feeding 4 liters of high-quality colostrum within the first 2-4 hours post-calving is mandatory for passive transfer of immunity.
What are the criteria for successfully weaning a calf?
Calves should double their birth weight (~75-85 kg) and consistently consume at least 1.5 to 2.0 kg of dry starter feed daily for 3 consecutive days before liquid milk is ceased.
What is the target Average Daily Gain (ADG) for dairy calves?
Pre-weaning ADG target is 750-900 g/day, accelerating to 800-1000 g/day until 6 months. This trajectory ensures heifers reach optimal breeding weight (360-380 kg) at 13-15 months.

4 Golden Rules of Calf Rearing

  1. Timely & Quality Colostrum: Feed 4 liters within 2 hours of life with a Brix refractometer reading > 22%.
  2. Early Starter Feed & Clean Water: Introduce calf starter and ad-libitum clean water from day 3. Volatile fatty acids from starter feed drive rumen papillae development.
  3. Weaning Discipline: Do not wean until the calf consumes at least 1.5 kg of solid starter daily for 3 consecutive days.
  4. Individual Hutches & Biosecurity: Individual hutches for the first 6-8 weeks drastically curb respiratory and enteropathogenic spread.
