Duration of Whole Milk Feeding for Calf Growth

Correct Answer: 90 days

Whole milk feeding is recommended up to 90 days (3 months) of age for proper growth and development of the calf. Beyond this, the rumen is sufficiently developed to utilise solid feeds effectively.

Calf Feeding Programme Summary

• Day 1–3: Colostrum @ 10% of body weight (critical for passive immunity)
• Day 4 onwards: Transition milk and whole milk
• Week 2 onwards: Introduce calf starter alongside milk
• Up to 90 days: Whole milk feeding (for proper growth)

Calf Starter Composition

Calf starter contains 18.5–19.5% DCP, 23–26% CP and 75% TDN. Intake of dry calf starter initiates rumen development and enables early weaning.
