Correct Option: A. N'dama and Moturu Explanation of the Correct Answer N'dama and Moturu Cattle Breeds: - N'dama Cattle: This breed is well-known for its resistance to trypanosomiasis, a disease caused by protozoan parasites transmitted by tsetse flies. N'dama cattle have a genetic adaptation that allows them to withstand the effects of the disease, making them a valuable breed in regions where trypanosomiasis is prevalent. - Moturu Cattle: Similar to N'dama, Moturu cattle also exhibit a high level of resistance to trypanosomiasis. They are indigenous to West Africa and have developed traits that help them survive in environments where the disease is common. The resistance of these breeds is attributed to their genetic makeup, which enables them to cope with the parasitic infection without succumbing to severe illness. This trait is crucial for farmers in areas affected by tsetse flies, as it allows for sustainable cattle farming without the heavy losses associated with trypanosomiasis. Why the Other Options Are Incorrect B. White Fulani and Biu: - White Fulani: While this breed is known for its adaptability and productivity, it is not particularly resistant to trypanosomiasis. In fact, White Fulani cattle are often affected by the disease, especially in tsetse-infested areas. - Biu: This breed is also not recognized for its resistance to trypanosomiasis. Instead, it is more susceptible to the disease, which can lead to significant health issues and economic losses for farmers. C. Red Bororo and Adamawa: - Red Bororo: This breed is primarily known for its hardiness and ability to thrive in harsh conditions, but it does not have a strong resistance to trypanosomiasis. Farmers raising Red Bororo cattle may still face challenges related to the disease. - Adamawa: Similar to Red Bororo, Adamawa cattle do not possess significant resistance to trypanosomiasis. They can be affected by the disease, which can impact their health and productivity. D. Wadara and Sokoro Gudali: - Wadara: This breed is known for its adaptability to various environments, but it is not specifically recognized for resistance to trypanosomiasis. Farmers may still encounter issues with this disease in Wadara cattle. - Sokoro Gudali: Like Wadara, Sokoro Gudali cattle do not have a notable resistance to trypanosomiasis. They can be susceptible to the disease, which can lead to health complications. Summary of Key Points

• N'dama and Moturu are the breeds of cattle that exhibit strong resistance to trypanosomiasis, making them ideal for farming in affected regions.
• Other breeds like White Fulani, Biu, Red Bororo, Adamawa, Wadara, and Sokoro Gudali are either susceptible to the disease or do not have significant resistance.
• Understanding the resistance of cattle breeds to diseases like trypanosomiasis is crucial for sustainable livestock farming in endemic areas.

Revision Summary

• N'dama and Moturu cattle are resistant to trypanosomiasis.
• Other breeds listed (White Fulani, Biu, Red Bororo, Adamawa, Wadara, Sokoro Gudali) are not resistant.
• Resistance is important for sustainable farming in tsetse-infested regions.
• Genetic traits play a key role in the resistance of certain cattle breeds to diseases.
