The relationship between the parity, the litter weight (LW) and some placental traits with goats was investigated in this study. 94 goat were investigated in total, 28 of which from first parity, 27 from second parity, 15 from third parity, 12 from forth parity and 12 from fifth parity. One-way ANOVA was used for statistical comparison, and Pearson correlation was used to determine the relationships between the variables. The goats’ placenta from the first parity weighs the least and the forth parity’s placenta is significantly (P<0.05) the heaviest. Significant differences in placental efficiency between the investigated animals were not discovered. Positive correlation was discovered between the weight of the placenta and the birth weight of the kid in the first, second and fifth parity. The results of this study show negative correlation between the weight of the placenta and the density of the cotyledons in goats of the first, second, third and fifth parity. Further studies are required to investigate the relationship between parity and placental traits in goats.
