Observations/notes:<br />
Offspring (males <strong>and</strong> females) usually can be kept in their familiar group at least until being four years <strong>of</strong> age with no problems. Mating between a<br />
breeding male <strong>and</strong> his daughter before this age is rarely observed <strong>and</strong> if it happens usually no pregnancy will follow it. Mating between breeding<br />
females <strong>and</strong> young males can be considered as social-learning <strong>and</strong> if no fights between males follow mounting, males can be kept in the group until<br />
being 4-5 years old, if not older.<br />
We need to improve survival <strong>of</strong> neonates. Close monitoring <strong>of</strong> animals after birth is recommended to identify the failure causes. Please try also to<br />
identify cause <strong>of</strong> death <strong>and</strong> send the necropsy reports to the EEP coordinator. In case <strong>of</strong> h<strong>and</strong>-rearing, early introduction <strong>of</strong> the <strong>of</strong>fspring to their<br />
parents is advisable. We had a problem <strong>of</strong> surplus males in the past but in the future we probably will be able to relocate almost all them.<br />
30 day mortality<br />
<strong>2007</strong>: 71.4% (5 <strong>of</strong> 7 neonates)<br />
<strong>2008</strong>: 50% (4 <strong>of</strong> 8 neonates)<br />
Total: 30 day mortality: 40.6% (50 <strong>of</strong> 123 neonates)<br />
