Abstract
It has been recognized that several physiological and environmental
factors affect milk production. The variations in the records due to these
factors are not necessarily attributable to cow's genetic merit. Removal of
the bias will facilitate precise genetic evalution essential for selection, progeny
testing and other herd improvement programmes. The purpose of this
study was to estimate in biasing effects of parity and environment on milk
yield in cross bred dairy cattle maintained at Livestock Research Station,
Kattupakkam in Tamilnadu.
