The present invention provides a method for beneficial control of body
condition and dietary energy balance in dairy cattle during colostrum milk
production. An important aspect of the beneficial control is the provision
of a feedstock which has a supplemented content of trans-10, cis-12
conjugated linoleic acid derivative having rumen-bypass properties. The
ingested quantity of CLA derivative ingredient per cow is effective for
lowering and maintaining the fat content of colostrum milk in the range
between about 4-6 weight percent and for increasing milk yield. The
presence of cis-9, trans-11 conjugated linoleic acid structural isomer in
an invention feedstock is minimized, because it counteracts the beneficial
effects of the trans-10, cis-12 conjugated linoleic acid structural
isomer, such as reduction in milk yield.
