This document discusses the external morphology and body condition of ruminants. It defines phenotype as the observable characteristics of an organism, like its morphology, development, and physiology. Genotype refers to an organism's genetic information in DNA. The document includes illustrations of dairy cow morphology, showing the internal and external structures of the mammary gland, as well as information on evaluating body condition in ruminants.
