________is primarily dependent on the quality of breeds in the dairy farm.

Answer

**Step-by-Step Solution:**

1. **Identify the Context**: The question asks about what is primarily dependent on the quality of breeds in a dairy farm.

2. **Understand Dairy Farm Products**: Dairy farms primarily produce milk and its derivatives such as ghee, cheese, and butter. The main focus here is on milk production.

3. **Recognize the Importance of Breeds**: The quality of the breeds (cows, buffaloes, goats) directly affects the yield of milk. Different breeds have different capacities for milk production.

4. **Compare Breeds**: For example, if one cow produces 10 liters of milk per lactation and another produces 20 liters, the second cow is a superior breed in terms of milk yield.

5. **Conclude the Dependency**: The yield of milk (quantity and quality) is primarily dependent on the quality of the breeds selected for the dairy farm. Higher quality breeds lead to better yields and thus better market prices for the products.

6. **Final Answer**: Therefore, the answer to the question is "Milk yield."
