Question

DCP requirement for maintenance of goat is

• A. 3 g kg BW^0.75
• B. 6 g kg BW^0.75
• C. 9 g kg BW^0.75
• D. 12 g kg BW^0.75

Hint:

Goat Nutrient Requirements (per kg $\text{W}^{0.75}$):
Maintenance DCP = $3\text{ g / kg W}^{0.75}$.
Maintenance TDN = $30 - 35\text{ g / kg W}^{0.75}$.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Nutrient requirements of small ruminants: maintenance digestible crude protein (DCP) requirements scaled to metabolic body weight ($ ext{W}^{0.75}$).
Key Formula or Approach:
\[ \text{Maintenance DCP Requirement of Goat} \approx 2.85 - 3.0\text{ g / kg } \text{W}^{0.75} \]

Step 2: Detailed Explanation:
According to ICAR and NRC feeding standards for goats:
- Maintenance protein requirements in small ruminants are expressed per unit of metabolic body size ($\text{BW}^{0.75}$ or $\text{W}^{0.75}$).
- The maintenance requirement for Digestible Crude Protein (DCP) in adult non-producing goats is 3.0 g kg BW$^{\mathbf{0.75}}$ (ranging from $2.85\text{ to } 3.12\text{ g/kg } \text{W}^{0.75}$).
- Total Digestible Nutrients (TDN) for maintenance is approximately $30 - 35\text{ g / kg } \text{W}^{0.75}$.

Step 3: Final Answer:
Thus, the DCP requirement for maintenance of goat is 3 g kg BW^0.75, matching option (A).
