ABSTRACT
The aim of this study was to find the effect of the administration of slow release boluse of trace elements bolus in Naemi ewes during late gestation. Thirty Naemi ewes were divided into two groups. One group served as a control while the other was treated with rumen bolus of trace elements containing copper (Cu) cobalt (Co); selenium (Se), manganese (Mn); zinc (Zn) and iodine (I). Blood samples were collected from ewes and their newborns at parturition. Colostrum yield and biochemical analysis at parturition was also determined. A significant (P<0.05) increase of calcium (Ca), Zn, Co and Se levels in blood of ewes treated with bolus with a significant increase in phosphorous (P), Co and Se in the blood of their newborn lambs. Furthermore, a significantly higher (P<0.05) inorganic matter percentage in colostrum was found in treated group compared to the control. The body weight of lambs in treated group at 30 and 60 days was significantly (P<0.05) higher when compared with the control. In conclusion, trace mineral boluses supplementation to pregnant ewes at late gestation improved minerals status of the ewes and their newborns at parturition and consequently enhanced body weight.
