Analysis of ewe's milk from twenty West African dwarf ewes collected from day one after parturition showed that the colostrum contained (mg/100ml) Ca 115.0 1 1,82, P 65.8± 4.08 Na 108.3 ± 2.0, K 163.2 ±1.74, Mg 17.9 0.78, CI 217.7 27.42, and (in mg/ litre) Fe 4.3±0.20, Cu 3.2 ± 0.17 Mn 0.21 ± 0.03, Zn 13.6 1 0.62, and Ug/litre of 1 311.2 ± 6.63. The corresponding values with standard deviation for the mature ewe's milk were Ca 129.5 ± 7.17 P 99.5 ± 6.20, Na 106.2 ± 1.46, K 149.7 $ 3.18, Mg 17.5 ± 1.51, CI 202.4 # 15.52 Fe 0.67. ± 0.38, Cu 0.41 ±0.39, Mn 0.07 ± 0.04, Zn 3.8 0.22 and 1 113.1 £ 28.78. The concentration of these elements in the colostrum approached that of the normal ewe s milk on the seventh day after parturition The results showed a rise in Ca P, Na Mg and C1 levels with stage of lactation and a fall in K, Fe Cu Mn, Zn and I contents of the milk with advancing lactation. .
