Osuji, B. Capper] Summary: Twenty-four Ethiopian Highland Zebu (Bos indicus) oxen were allocated to 6 groups of 4 animals each on the basis of liveweight, age and body condition according to a completely randomised block design. The animals were group-fed an experimental diet consisting of (g/kg) 551 g concentrate and 449 g teff straw, at the rate of 2·5 kg per 100 kg of liverweight for 18 weeks. They were weighed and condition scored weekly. Feeding levels were adjusted weekly. The daily liveweight gain of each animal was estimated using regression analysis and changes in condition score evaluated. Age significantly affected the liveweight gains and body condition score changes of the oxen. There was a significant (P<0·001) linear effect of age on average liveweight gain. The average daily gains were 0·62, 0·51 and 0·41 kg/day for animals aged 4 to 5, 7 to 8 and 10 to 11 years respectively. Age exhibited a significant (P<0·05) quadratic effect on body condition changes. The results are discussed in terms of benefits from traction and fattening and farm system implications of fattening younger animals for reproduction and improved feeding.
