Abstract: A total of 6 lactating does of the West African Dwarf (WAD) breed, in their first lactation stage and parity, were understudied in Michael Okpara University of Agriculture farm and in the village around the university campus for a period of 60 days.Total 3 animals in the university farm were fed cut-and-carry forages consisting mainly of Guinea grass (Panicum maximum) while the 3 in the village grazed available forages and house wastes. The two groups of lactating does were supplemented daily with a concentrate formulation of 14.3% CP. The animals were hand milked daily from 6-8 am and yield determined for each group. Samples of milk were analysed for Total Solids (TS), Butterfat (BF), Crude Protein (CP), Solids-Not-Fat (SNF), lactose, total ash and Gross Energy (GE). Milk productions of both groups were also corrected for fat (FCM). The results showed that goats kept in the university farm were higher in yield and milk constituents than does raised in the village except for lactose, SNF, protein and ash contents. Milk yield and FCM values for the university and village does were 122.0 ± 0.08; 137.4 ± 14.51 and 102.0 ± 0.03; 103.3 ± 18.80 g, respectively; the differences between the two means were highly significant (p< 0.001). The butterfat (4.84 ± 0.80; 3.76 ± 0.38%) and the energy contents (1.84 ± 0.35; 1.41 ± 0.41 MJ kg 1) of both milks were also significantly different (p< 0.001). The university does had higher butterfat and energy contents. The protein and lactose values, though similar (p>0.05) for both groups, were also 4.25 ± 0.32; 4.57 ± 0.34 and 4.37 ± 0.50; 4.34 ± 0.50% for the university and village does, respectively. High positive and significant correlation existed between BF and TS (r = 0.82; p< 0.001); energy and BF (r = 0.84; p< 0.001); and energy and TS (r = 0.99; p< 0.001) in the university animals. In the village does, the relationship between energy and butterfat was also positive and highly significant (r = 0.99; p< 0.001) but positive and non-significant between CP and TS (r = 0.01; p>0.05) and between lactose and TS (r = 0.38; p>0.05). Differences between the various milk constituents of the two groups of animals were minimal.
