Enhancing dairy milk CLA by tailoring rumen
dynamics through dietary manipulations
M. Aasif Shahzad

C
onjugated linoleic acid (CLA) has been recognized to
impart health benefits to human beings by supporting
or manipulating health protecting mechanisms. Bovine
milk is considered an important source of this valuable
fatty acid; however, its synthesis by the dairy cow is
influenced by multiple factors, among which dairy feed is
one of them. Fabricating dietary nutrients to feed the dairy
animal aimed to enhance its CLA has offered a tool to
be used to synchronize the dietary, ruminal and cellular
nutrient interaction and utilization to achieve higher CLA in
milk. This article will underline how dietary feed Ingredients
can alter rumen dynamics and milk biosynthesis to attain
a higher CLA in dairy milk fatty acid profile. Studies
indicate changes in milk CLA might be attributed to the
diversity of fat sources and varying concentration of
forage and concentrate. However, role of nutrients which
are degraded and / or undegraded in rumen can’t be
neglected. Feeding type of fat which doesn’t break in
rumen and certain amino acids which break and don’t
break in rumen are important tools to design milk fatty acid
profile with higher CLA. Dietary fat may influence the bio
hydrogenation phenomena in the rumen which has direct
impact on milk fatty acid profile. Feeding type of protein
which is not degraded in the rumen have been reported
to enhance the milk CLA, however, this impact of dietary
protein may be affected by composition and quantity of
amino acids which don’t break in the rumen. Biosynthesis
of milk need precursors or nutrients which dairy Animal
gets form blood which reflects the existence of an
isotonic equilibrium between blood and milk. This abstract
review and underline the dietary interventions aimed to
synchronize dietary nutrients to tailor rumen dynamics
towards synthesis of nutrients or their precursors for
higher milk CLA and this nutritional avenue still awaits to
be capitalized for better human nutrition.
