Nutritional Profile of Calf Starter
Calf starter contains:
- 19% DCP, 25% CP & 75% TDN — Correct Answer
- 22% DCP, 25% CP & 75% TDN
- 20% DCP, 18% CP & 70% TDN
- None
Explanation:
Correct Answer: 19% DCP, 25% CP & 75% TDN
A calf starter is a specially formulated concentrate feed introduced from the 2nd week of age to stimulate rumen development and support early weaning. Standard values: DCP 18.5–19.5%, CP 23–26%, TDN 75%.
Calf Starter — Nutritional Profile
| Nutrient | Value |
|---|---|
| Digestible Crude Protein (DCP) | 18.5–19.5% (~19%) |
| Crude Protein (CP) | 23–26% (~25%) |
| Total Digestible Nutrients (TDN) | 75% |
| Introduction age | From 2nd week of age |
Purpose of Calf Starter
- Intake of dry feed → initiates rumen development
- Allows early weaning (reduction of whole milk dependency)
- High CP and TDN ensure adequate growth even with reduced milk intake
Why Other Options Are Wrong
- 22% DCP, 25% CP, 75% TDN → DCP of 22% is too high; standard is 18.5–19.5%
- 20% DCP, 18% CP, 70% TDN → CP of 18% is too low (below protein supplement threshold of 20%); TDN of 70% is also below standard
- None → incorrect; the given values match standard calf starter specifications
