dc.description.abstract The objective of this study was to determine the effect of breed, parity, season of lactation, udder and teat sizes, and feed supplementation on milk yield of dual-purpose cattle in four districts of the Ashanti Region in Ghana. A total of 328 cows kept under farmers? own management that calved and lactated were involved. Milk yield was measured in litres per cow for three times at four weeks interval in three seasons. All the fixed factors, except udder size influenced (p<0.01) milk yield. Average daily milk yield per cow across breeds was 2.0 litres. Average daily milk yield per cow for N?dama, West African Shorthorn, Sanga, White Fulani, Sanga-Gudali crossbred and Sokoto Gudali were 1.5, 1.5, 1.9, 2.0, 2.8 and 3.5 litres (p<0.01), respectively. Milk yield increased with increasing parity and started dropping in the seventh parity. Cows that calved in the major season had the best (p<0.01) milk yield followed by those lactated in the minor season. Average daily milk yield for small, medium and large teat size were 2.0, 2.5, and 2.7 litres (p<0.01), respectively. Average daily milk yield per cow receiving no feed supplementation, occasional and regular feed supplementation were 2.1, 2.2 and 2.8 litres (p<0.01), respectively. Cows in good body condition performed better (p<0.01) than thin and over-conditioned cattle. It was concluded that Zebus and their crosses had better average milk yield than Taurine breeds. Also regular feed supplementation, increased teat size, moderate to good body condition led to increased milk yield. Cows with reduced milk yield after the 6th parity should be replaced for higher economic returns. en_US
