Which dairy cattle breed is commonly known for the highest milk production?

• A. Jersey
• B. Holstein
• C. Guernsey
• D. Brown Swiss

Answer: (B)

Milk production varies by breed, with genetics and body size largely determining how much milk a cow can produce in a lactation. Holstein cows are the most prolific producers among common dairy breeds, having been intensely selected for high daily milk output. Their large size supports higher total volume, so they typically produce more milk over a lactation than Jerseys, Guernseys, or Brown Swiss. While Jerseys may excel in milk fat and protein content per unit, the overall milk volume is highest in Holsteins. Management and nutrition also play important roles in actual yields.
