Abstract
This study aims to evaluate the milk composition, minerals and fatty acid profile of milk of West African Dwarf Does Goats fed under different feeding time. Twelve lactating pregnant West African Dwarf (WAD) goat-does on their parity were randomly allocated into the morning, afternoon, and evening time of feeding in a Complete Randomized Design. This experiment lasted four weeks. The result shows that milk proximate composition of evening-fed does had the highest milk lactose (9.84%) and the highest milk fat (10.86%), while afternoon-fed does had the highest milk protein (8.26%). Afternoon-fed does had the highest milk phosphorus (P = 0.05) while evening-fed does had the lowest. Tridecanoic, myristic, myristoleic, stearic, Υ - linolenic, total linolenic acid, PUFA, PUFA/SFA and atherogenicity were statistically (P < 0.05) influenced by the time of feeding. Change in the time of feeding can invariably determine the milk content and pattern of fatty acid synthesis.
