Udder Morphology Traits and Milk Production of Najdi and Naeimi Ewes under Intensive Condition

A total of fifty multiparous ewes were selected immediately after lambing to study the relationship between udder morphology traits and milk production Najdi Naeimi (n=25/ breed) under intensive Saudi Arabia condition. Immediately lambing, lambs allowed suckle freely for 8 weeks; there weaned. During suckling period, typology, depth suspensory ligament in wear visually evaluated 3 weeks lambing. One week before weaning (Week 7), measurements daily yield potential determined. After 9), composition determined, as well cisternal alveolar was measured 8h morning milking. Udders Type II most frequent (45.6%) both breeds. However, breed showed a higher incidence (19.3%) III, whereas sheep presented larger percentage (29.8%) I udders. The IV high (17.6%) two presence suspensors ligaments observed 75% 46% ewes, respectively. proportion with over level hook 51% 56%, Litter size gender did not affect (p > 0.05) measurements, but significantly < affected teats length width. In addition, lamb’s birth weight teat angle 0.01) ewes.
