Digestive System
Muhtasari
Put a pig and a goat in the same paddock in Jos and feed them nothing but dry maize stover for a week. The goat holds its condition. The pig loses weight fast. Both animals have a mouth, a stomach and intestines, so the difference cannot be that one eats and the other does not. The difference is what happens between the mouth and the intestine, and that is the whole subject of this lesson.
You will trace two digestive tracts organ by organ: the pig's simple, single-chambered system, and the cow or goat's four-compartment ruminant system. You will meet the rumen's population of microbes, the only workforce on the farm that can actually break down cellulose, and see exactly why a compound stomach turns rough, fibrous, cheap feed into meat and milk. Nearly every later topic on nutrition and feeding assumes you already know this system cold, so build it carefully now.
