Overview

This study was conducted in El-Nuhoud locality, North Kordofan State (2010 / 2011) with the objective of studying the effect of supplementary urea on reproductive performance of desert sheep. The study used 48 Hammari desert ewes and two rams at the rate of one ram ∕ 24 ewes. The ewes were randomly divided into four equal groups. All groups were left to graze naturally throughout the day. The first group drank water daily with urea (T1), the second group drank water daily without urea (T2), the third group had access to water every other day with urea (T3) and the fourth group was watered every other day without urea (T4). The new born lambs of these groups weighed weekly and the body measurements included (height at withers, heart girth, body length, head length, ear length, neck length and tail length). The litter sizes of newborns were weighed and recorded. The results showed that the performance of lambs significantly (P ≤ 0.05) affected by the different treatments. The average weight of newborn lambs in the initial week was 3.6 kg and it was increased to reach 24.46 kg in the final week. The results revealed that the urea supplementation of dams gave the highest mean values in the body measurements especially height at wither, heart girth and body length recorded the highest values in treatment supplementary urea with daily water access. Hence, daily watering access and supplementary urea was important for flushing to improve the productive and reproductive performance of lambs.
