FORAGE IN RUMINANT RATIONS
established, but both have drawbacks,
with particular reference to environmental, cost and safety issues.
Organic techniques include
enzymes, bacterial silage inoculants
and use of yeast additives. Enzymes,
such as phytase, are more commonplace in non-ruminant diets but less
so in the ruminant sector. Beneficial
effects have been seen with dietary
addition of exogenous enzymes, but
results have been inconsistent and are
likely to restrict greater adoption of
this method.

Balanced rations
Ensuring a balanced ration in terms
of energy and protein will also aid
forage fiber utilization. Synchrony
between energy and protein stimulates microbial growth and activity,
which, in turn, should increase fiber
digestion. Fiber-digesting microbes
require a nitrogen source, predominantly in the form of ammonia.
However, without sufficient energy
to be able to utilize this nitrogen
source, microbes are unable to
generate microbial protein and

proliferate, and fiber digestion can
be compromised.   
Ultimately, environmental and
economic pressures will only increase
for ruminant livestock production.
Fiber is a critical component of ruminant diets and offers benefits in terms
of land use in certain areas. However,
energy derived from fiber can be
suboptimal, so any applications that
increase utilization from fiber should
increase sustainability in an increasingly volatile market. ■
