Choosing Livestock for Control by Grazing

Large mammal grazers have evolved three basic principles for dealing with cellwall breakdown 1. Ruminants (e.g. sheep, cattle) have pre-stomach fermentation and an emol-liating tank, where micro-organisms break down cell walls. The food bulk is emolliated in fluid, regurgitated, re-chewed and finally sent to the animal's proper digestive system, resulting in a long gastro-intestinal passage time. 2. Hindgut fermentators (e.g. horses) pass food through the normal digestive system first, i.e....
