Path Analysis for Factor Affecting the 305- Day Milk Yield of Holstein Cows

Abstract

Path Analysis is one of the most widely used methods in animal husbandry, especially in dairy science. This method, which is used to calculate the direct and indirect effects of the dependent and independent variables in the model on each other, offers researchers a very detailed interpretation. In this study, direct and indirect effects of lactation number, calving season, dry period, service period and insemination number variables on 305-day milk yield of 1007 Holstein cows were investigated by Path analysis. Analysis of the study was carried out with IBM SPSS 26.0 and IBM SPSS AMOS 21 program. The direct effects of lactation number (-0.061) and calving season (0.027) variables on 305-day milk yield were not statistically significant (p>0.05). The direct effects of dry period (-0.354), service period (-0.505) and insemination number (0.386) variables on 305-day milk yield were found to be statistically significant (p<0.05).
