Characteristics of lactation performance, based on AM milk offtake and conformation, of Ankole cattle were studied during one year in 37 herds with 606 recorded cows in Mbarara district in southwestern Uganda. Recording of AM milk offtake was undertaken in eight areas of Mbarara district which represent different production systems and vegetation types.

The 467 cows with complete lactation cows yielded, on average, a total AM offtake of 252 and 325 kg over first and second or higher lactations, respectively. These offtakes were higher than other African indigenous populations in pastoral systems. Mean body weight was 292 and 341 kg for first and second or higher parities, respectively. Average body measurements for all parities were 161 cm for heart girth, 129 cm for height at withers and 193 cm for body length.

The daily AM milk offtake varied from 1.1 kg in the Ruhengere area characterized by thorny Acacia thickets to 1.9 kg in the bush-cleared Kanyanya area with improved pastures. Although the Ankole cows performed best on the improved pastures, their future may relatively be more favourable in the original non-cleared bush areas because of the gradually increasing competition from exotic dairy breeds and their crosses.
