An example of a triangle diagram appears to the right. An organizational chart is the diagram of a hierarchy within an organization, and is depicted in tree form below.
Cow's milk can range from 3.7 to 5.1% lactose, although most milk in the U.S. is around 5%. So water buffalo milk may be slightly lower in lactose but not significantly so. I certainly wouldn't call it a low lactose product.
Over 95% of water buffalo are found in Asia. More than one-half of the remainder are found in Africa, primarily Egypt. The annual milk yield of good cows, depending on strain, is between 1500 and 3000kg. Buffalo milk contains 7-8% fat.
