Abstract

Analysis of ewe's milk from twenty West African dwarf ewes collected from day one after parturition showed that the cplostrum contained (mg/ l00ml) Ca 115.0 ± 1.82, P 65.8 ± 4 .08 Na 108.3 ± 2.0, K J63.2 ± 1.74, Mg 17.9 ± 0.78, CI217.7 ± 27.42,and{inmg/ litre) Fe 4.3±0.20, Cu 3 .2 ± 0.17 Mn 0.21 ± 0.03, Zn 13 .6 ;t 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 I 113.l ± 28.78. The concentration of these elements in tho colostrum approached that of the normal ewes milk on the seventh day after parturition. The results showed a rise in Ca P, Na Mg and Cl levels with stage of lactation and a fall in K, Fe Cu Mn, Zn and I contents of the milk with advancing lactation
