Apart from the fact that there are so many differences between goats and lambs, both animals belong to the same class i.e., mammalian class. However, one of the differences between the two mammals is that both belong to different species. Both can be differentiated by comparing the number of chromosomes in the two animals. While a goat has 60 chromosomes, the number of chromosomes in a lamb is 54.
Although the two are herbivorous animals, you will definitely notice certain differences in their eating habits. Goats are more intelligent than lambs, and they are not as sluggish as lambs. Unlike goats that have a particular kind of smell, lambs don't have a distinctive smell. Also, lambs are mostly hornless animals except for some, whereas goats have horns, and they use their horns to defend themselves. The milk of lamb contains more fat compared to that of goats. Also, goats don't have the same fat and cholesterol content as lambs.
