Human milk has a fat percentage of 4.5, protein of 1.1%, and 6.8% lactose.
Cow's milk's fat percentage is 4.1, depending on the breed of cow, 3.6% protein, and 4.7% lactose.
Rabbit milk has 12.2% fat, 10.4% protein, and only 1.8% lactose. The smallest bit of sugar and high fat and protein is perfect for those little growing baby bunnies.
There are much more animals and their milks listed on the page. I encourage you to check it out! I really like it and find it very intriguing!
