This study used path analysis and a simple correlation coefficient to identify the factors that affect bodyweight in various artificial pastures. During the first year of the study, two distinct artificial pastures covering 1.5 hectares each were set up. A total of 20 male Holstein animals, were randomly assigned to the experimental regions. The animals' body weight (BW) and other morphometric parameters were ascertained. The findings demonstrated a strong correlation between bodyweight measures and bodyweight. There were found to be strong and positive relationships between body length and body weight (BL) (0.89**), Wither Height (WH) (0.88**), Heart Girth (HG) (0.93**), Hip Height (HH) (0.83**) and Hip Width (HW) (0.84**). Numerous morphometric variables had an indirect or direct impact on bodyweight. After being determined to be non-significant, the regression model's standardized correlation coefficients for BL and HH were eliminated. A determination coefficient (R2 of 0.93) was achieved for the ideal multiple regression equation for animals. The measurements (HG, WH, HW, and BD) were shown to have statistically significant direct effects on cattle's body weight (BW), according to the results. It is possible to draw the conclusion that HG is a significant parameter to accurately estimate the bodyweight of cattle even under grazing settings.
