Abstract: The milk yield and compositions of 9 lactating cows made up of 3 Muturu, N�dama and White Fulani dams were compared in a 12-weeks study. The animals in their early lactation and 1st parity grazed natural pasture and each received in addition 1 kg day ¹ of 17% CP concentrate supplement. Milking was once a day (0800-0900 h), daily milk yield was quantified and bulked weekly per animal per breed. Lactose was determined in milk samples daily while bulked samples were analysed for Total Solids (TS), Butterfat (BF), Solids-not-fat (SNF), Crude Protein (CP) and ash. Results showed that average weekly milk yield generally increased (p<0.05) with lactation and attained peak production in weeks 7 and 11 for Muturu (0.77 kg) and N�dama (1.34 kg) cows, respectively. The White Fulani however attained peak production in weeks 12 (2.43 kg) or probably beyond. All milk constituents differed significantly within weeks among breeds (p<0.05) except TS and SNF in N�dama and lactose in Muturu and White Fulani. In Muturu, TS and SNF had peak concentrations in week 4, BF in week 1 and CP and ash in weeks 11 and 12, respectively; lactose was fairly constant (p<0.05). In N�dama, TS, SNF and ash were fairly constant (p<0.05), while BF, lactose and CP were highest in weeks 1, 4 and 12, respectively. For White Fulani, weekly lactose values did not differ significantly (p<0.05), however, the highest comparable values for TS were in 5th and 8-12th week, BF (1-4th week), SNF (5th, 7-12th week), CP (9-11th week) and ash (8th, 11-12th week). White Fulani produced significantly (p<0.05) more milk than any other breed in all the weeks of study. N�dama had superior (p<0.05) TS in milk in weeks 1, 3 and 4 and thereafter this milk component remained fairly constant for all breeds. BF differed significantly (p<0.05) in weeks 1 and 7 among the breeds, SNF in weeks 1, 3 and 4, CP in weeks 1 and 6 and ash in week 4. Lactose in the milk was not influenced by breed (p<0.05) within the weeks of study. Milk yield of different constituents can be harnessed from Nigerian indigenous cattle through timed articulated milking programme.
