Abstract: Halayeb-Shalateen and Abu Ramad Triangle is located at the border between Egypt and Sudan, on the African coast of the Red Sea and has an area of 20,580 square kilometers.Livestock in Halaieb-Shalateen-Abu Ramad Triangle is limited in sheep and goats.Aboudeleik sheep is considered one of the important breeds to produce milk and meat in the Triangle, because of their persistence to the harsh conditions (Khalil et al., 1990).The average body weight is 45 kg and the body is shallow with long legs and covered with short hair.The head, neck are long in both sexes long often with dewlap.The tail is cylindrical and longreaching below the hocks; ears are absent or small with backward downward.The color is dark or brown with cream; wattles are rare (DRC, 1996).The pasture in Halaieb-Shalateen-Abu Ramad triangle region contains three main plants which are poor in nutritional value, namely Panicum turgidum, Lyicum shawii and Acacia tortilis (El-Shaer et al., 1997).There is no available information about reproductive performance, production characteristics and estimates of the genetic parameter (Badawy et al., 2018).Metabolism of blood biochemical and trace minerals in sheep are still yet to be clarified under arid conditions and environmental stress during different physiological status (Samir, 1990).Trace elements supplementation has become indispensability in the feeding of ruminants (Kim and Mahan, 2002;
