There is no such thing as a "female cow" nor a "male cow." "Cow" refers to the female of any species including the domestic bovine, and is not a name of a specific animal. The male of a domestic bovine is called a bull, and the female (mature) a cow. To answer your question, it is the bull that is the larger of the two in most cases, such as within breeds and when the bull and the cow are the same age. But, if you compare between breeds, such as if the bull is a Dexter and the cow a Holstein, or if the bull is much younger than the cow, then the opposite may be true.
When you mix cow breeds, you create a crossbred animal that inherits traits from both parent breeds. This can lead to improved performance in areas such as growth rate, milk production, or disease resistance. However, the resulting hybrid may not breed true in subsequent generations.

The phrase "What comes cow but is not white" could refer to "cow" as a term used in various contexts, such as "cow's milk" which can be processed into products like cheese or yogurt, often not white in color. Additionally, there are breeds of cows that are not white, such as Holsteins, which are black and white, or Jersey cows, which are typically brown. Therefore, the answer could encompass both the products derived from cows and the diversity of cow breeds.
