خلاصه: Ruminants thrive from the tropics to the Arctic Circle and serve mankind by making
“something from nothing.” By readily harvesting and digesting diverse forage
resources from inaccessible and nonarable land and forests, and converting otherwise
wasted agricultural and industrial by-products and low-cost grain surpluses
into milk, meat, and fi ber, ruminants make products that are highly prized by humans
worldwide. For optimum economic effi ciency of production, ruminant producers
must assure that both the host ruminant and the microbial population within the
rumen receive an adequate but not excessive supply of essential nutrients and
energy, appropriate rumen modifi ers, and proper animal care, management, and
attention to maintain health and productivity. This text includes information and
concepts compiled by specialists in microbiology, rumen function, and animal
health around the globe. It is intended to supply both students and livestock producers
with a framework in rumenology that when applied will help make ruminants
more productive and sustainable by enhancing the effi ciency of conversion of
energy and nutrients from land devoted to either grazing or crop production into
useful and valued products while minimizing the adverse effects of ruminant production
on the environment
