The objective of this study was to analyze the chemical and mineral composition of aborted goats as well as goats withnormal kidding for an entire lactation (five months; rainy season under range conditions), and the effect of stage oflactation on various raw milk components. Thirty one multiparous goats of mixed-breed goats were used, 16 carried theirpregnancy to term and 15 aborted about the fourth month of pregnancy. Percentage of milk fat fluctuated greatly (P<0.01)throughout lactation with no differences between aborted and non-aborted goats (5.0 vs. 4.8 g/100 g). Percentage proteinwas higher (P<0.05) in aborted goats compared to non-aborted goats (4.7 vs. 4.5 g/100 g). During the early stage oflactation, milk contained higher (P<0.01) lactose levels which then decreased gradually towards the end of lactation. Nodifference in this milk component was detected between groups of goats (4.6 vs. 4.5 g/100 g). Both magnesium andmanganese in goat milk were higher in aborted than non-aborted goats. It was concluded that some milk components areincreased in milk from goats whose lactation initiate with abortion, compared with milk from goats whose lactation derivefrom normal kidding.
