A Study on Direct and Indirect Effects of Some Factors on Weaning Weight of a Awassi Lambs


Abstract: The correlation coefficients divided into direct and indirect effects among ewe weight in the mating period and lambing, birth weight and weaning age of lamb, and weaning weight of Awassi lambs raised in Erzurum conditions were determined in this study. In path analysis, the direct and indirect impact of birth weight and weaning age of lamb on weaning weight were found to be highly significant. Partial correlation and standardized partial regression coefficients among weaning weight, birth weight and weaning age of lamb were also observed to be highly significant.

Keywords: Path Analysis, Correlation Coefficient, Partial Regression Coefficient.
