What was the source video for the data BTW? I'm a little unsure about some of these, like cows having 5% body fat! According to this[0] webpage a "moderate" condition cow has 19% body fat, but it has a "Body Composition Score" of 5.
The body fat content for many animal species varies a lot throughout the year based on migration, food availability, and (sometimes) hibernation. So it depends on when you measure.
That seems suspicious.
