Correct Option: B. Meat production Detailed Explanation: The N'dama breed of cattle is primarily raised for meat production, which is a significant aspect of its utility in agricultural systems, particularly in West Africa. Here’s a step-by-step breakdown of why option B is the correct answer:

1. Breed Characteristics: The N'dama breed is known for its adaptability to tropical climates and resistance to diseases, particularly trypanosomiasis (sleeping sickness), which is prevalent in many regions where these cattle are raised. This resilience makes them suitable for meat production in areas where other breeds may struggle.
2. Meat Quality: N'dama cattle are recognized for producing high-quality beef. The meat is often leaner and has a good flavor profile, making it desirable in local and regional markets. The breed's ability to thrive on low-quality forage also contributes to its efficiency in converting feed into meat.
3. Cultural and Economic Importance: In many West African communities, cattle are not only a source of meat but also play a crucial role in the economy and culture. The N'dama breed is often preferred for its meat, which is a staple in the diets of many people in these regions.
4. Production Systems: N'dama cattle are typically raised in extensive grazing systems, where they can roam freely and graze on natural pastures. This system is conducive to meat production, as it allows the cattle to grow and develop naturally.

Why Other Options Are Incorrect:

• A. Fiber production: This option is incorrect because N'dama cattle are not known for producing fiber. Unlike sheep or goats, which are raised for wool or hair, cattle are primarily valued for their meat and milk. The N'dama breed does not have a significant role in fiber production.
• C. Milk production: While N'dama cattle can produce milk, they are not primarily raised for this purpose. Other breeds, such as Holsteins or Jerseys, are more commonly associated with high milk production. The milk yield of N'dama cattle is generally lower compared to specialized dairy breeds, making them less favorable for milk production.
• D. Draft power: Although N'dama cattle can be used for draft purposes, this is not their primary role. Many farmers may use them for plowing or transportation, but the breed is predominantly valued for its meat. Other breeds, such as oxen, are more commonly used for draft power in agricultural settings.

Summary of Key Points:

• The N'dama breed is primarily raised for meat production due to its adaptability and disease resistance.
• They produce high-quality beef, which is economically and culturally significant in West Africa.
• Other options (fiber, milk, draft power) are not the primary reasons for raising N'dama cattle, as they are less efficient or relevant compared to meat production.
