Diet
Goats are reputed to be willing to eat almost anything. The digestive systems of a goat allow nearly any organic substance to be broken down and used as nutrients.
Contrary to this reputation, they are quite fastidious in their habits, preferring to browse on the tips of woody shrubs and trees, as well as the occasional broad leaved plant. However, it can fairly be said that goats will eat almost anything in the botanical world. Their plant diet is extremely varied and includes some species which are toxic or detrimental to cattle and sheep. This makes them valuable for controlling noxious weeds and clearing brush and undergrowth. They will seldom eat soiled food or contaminated water unless facing starvation. This is one of the reasons why goat rearing is most often free ranging since stall-fed goat rearing involves extensive upkeep and is seldom commercially viable.

Goats do not usually consume garbage, tin cans, or clothing, although they will occasionally eat items made primarily of plant material, which can include wood. They have an intensely inquisitive and intelligent nature: they will explore anything new or unfamiliar in their surroundings. They do so primarily with their prehensile upper lip and tongue. This is why they investigate items such as buttons, camera cases or clothing (and many other things besides) by nibbling at them, occasionally even eating them.
The digestive physiology of a very young kid (like the young of other ruminants) is essentially the same as that of a monogastric animal. Milk digestion begins in the abomasum, the milk having bypassed the rumen via closure of the reticular/esophageal groove during suckling. At birth the rumen is undeveloped, but as the kid begins to consume solid feed, the rumen soon increases in size and in its capacity to absorb nutrients.
Goats will consume, on average, 4.5 units of dry matter per 100 units of body-weight per day.
