Headgear evolution remains an open and intriguing question because phylogenies (molecular and ...
متن کاملNitrogen Metabolism in the Ruminant: a Review
Current systems for the evaluation of protein-feeds for ruminants take account of two principal nitrogen (N) requirements. One is to satisfy the needs of the rumen micro-organisms in order to maximize. microbial protein yield this N can largely be provided in any form that will give rise to enough ammonia in rumen fluid. The other N requirement is for a dietary source of true protein that wi,ll...

Tannins are a complex group of polyphenolic compounds found in a wide range of plant species commonly consumed by ruminants. They are conventionally classified into two major groups: the hydrolysable and the condensed tannins. Although for a long time tannins were thought to be detrimental to ruminants, their effect may be either beneficial or harmful depending on the type of tannin consumed, i...
