This study was conducted during the rainy season to determine and compare milk composition of 'camels and goats that are grazing in the same extensive system (Butana area in Sudan). It aimed also to assess the chemical composition and some essential minerals of the mixed pasture in Butana area. Two hundred and forty milk samples were randomly collected form lactating camels and lactating goats (120 from each). These samples were examined to determine the percent of total solids, fat, protein, ash and lactose. Also some minerals (Ca, P, Mg, Na, K, Zn, Co and I) were determined. Camel milk constituents were 11.95+ 0.47, 4.14± 0.28, 3.22± 0.21, 0.83± 0.05 and 3.74+0.37% for total solids, fat, protein, ash and lactose, respectively. Goat milk constituents were 11.55+ 0.47, 3.48± 0.26, 3.29± 0.26, 0.69± 0.03, and 4.05± 0.43, respectively. Minerals of camel milk were 119.27+ 3.43, 83.58+ 7.64, 12.43+ 0.94, 68.58+ 3.52, 160.50+ 9.23, 0.519+ 0.035, 0.06380.0069 and 0.0357+ 0.0067% mg/ 100 ml for Ca, P, Mg, Na, K, Zn, Co and I, respectively. While minerals concentration in goat milk were 127± 3.42, 66.36+ 9.91, 11.86+ 1.28, 41.91+ 7.02, 133.57+ 10.42, 0.326+ 0.030, 0.0559+ 0.0084 and 0.031.7+ 0.0049 mg/ 100 ml, respectively. The result showed that there were non significant differences (P>0.05) between milk of camels and goats in total solids, fat, protein, lactose, P, K, Zn, Co and I levels. While significant differences (P<0.05) in ash and Mg levels were observed. Also, highly significant differences in Na and Ca concentration were estimated (P<0.01 and P<0.001), respectively. Fifteen samples of mixed grasses from the natural grazing pasture were collected
