Approximately what percentage of milkfat and nonfat milk solids does Holstein cow milk contain?

Holstein cow milk is known for its specific composition of milkfat and nonfat milk solids. The typical percentage of milkfat in Holstein milk is approximately 3.7%, and the nonfat milk solids typically make up about 8.7%.

This composition is important for various dairy products and is recognized for its consistency across many Holstein herds, making it a standard reference point in the dairy industry. The milkfat contributes to the richness and creaminess of products, while nonfat milk solids, which include proteins, lactose, vitamins, and minerals, are crucial for the nutritional value of milk.

In contrast to the other options, they either present percentages that are too high or too low for Holstein milk. For instance, a higher fat percentage like 4.0 would not be representative of the breed, and lower nonfat solids percentages such as 7.5 or 8.0 do not reflect the typical nutritional data associated with Holsteins. Hence, the accurate composition of 3.7% milkfat and 8.7% nonfat milk solids is what makes this choice correct.
