Title: The minerals profile in desert ewes (Ovis aries): effects of pregnancy, lactation and dietary supplementation.
Author: Abdelatif, Abdalla M.; Elnageeb, M. E.
Abstract: The objective of this study was to assess the changes in serum minerals profile in desert ewes in relation to pregnancy, lactation and dietary supplementation. Twenty sexually mature Sudanese desert ewes was assigned to two equal groups, control and supplemented; the supplemented group received daily (500 g) of concentrate mixture (crushed sorghum+cotton seed cake). In both groups, oestrus was synchronized with hormonal method and the ewes were naturally inseminated. Following insemination, pregnancy was confirmed by ultrasonography technique. The results indicate that in both groups of ewes, the serum levels of (K), (P) and (Mg) increased significantly with the advance of pregnancy. The serum levels of (Na), (K), (Ca), (P), (Mg), (Cu) and (Zn) which were higher in supplemented ewes, increased significantly at parturition and decreased gradually with the advance of lactation. During lactation, the supplemented ewes maintained higher levels of serum (Na), (K), (Ca), (Cu) and (Zn). The results indicate that the mineral profile in desert ewes is influenced by pregnancy and lactation and the responses are modified by dietary supplementation.
