Abstract :
Ninety nine Awassi ewes, lambed through the lambing season of 2004 (75 singles and 24 twins) were used for investigating the effect of some non-genetic factors (sex, type of birth, and ewe weight and parity at lambing) on some placental factors (placental weight and cotyledons number). The relationship between placental traits and litter weight at birth was also investigated. The results shown that ewe age and parity, sex, type of birth and type of birth have significant (P< 0.001) effect on placental traits as well as birth weight of neonates. A highly significant positive correlation was estimated between placental traits (placental weight and cotyledons number) and litter weight at birth.
