In Ethiopia, Boran and Arsi indigenous cows have been crossbred with Friesian and, or, Jersey sires in an attempt to increase milk production, especially in the Highlands (Kiwawa et al., 1983; Beyene, 1984). However, significant increase in milk production from crossbred cows have been constraine...

Between and within-breed variations in feed intake and digestive efficiency, in terms of the percentage of feed dry matter (DM) retained in the body out of that consumed (ADMD), in 452 Menz and Horro sheep were estimated. Average daily concentrate DM was about 278 g/day in both breeds, whereas da...

Draught animals are the main integrative links between crop and livestock production systems in the highlands of Ethiopia. The highlands comprise only 40% of the country's total land area but carry 79% of livestock heads and 80% of the human population results in higher pressure on the arable lan...

The study investigated the effect of work on the postpartum estrous cycle length and ovarian activity of crossbred dairy cows used for draught. Sixteen dairy cows were assigned to two dietary feeding regimes (i.e. diet 1=9 MJ ME/kg DM; diet 2=10 MJ/kg DM). The cows in both diets started to work a...

The experiment was carried-out at the ILRI Debre Zeit Research Station in Ethiopia. Sixty three Ethiopian Highland Zebu Bos indicus) oxen were ranked by weight and blocked in a completely randomized block design. Nine representative oxen from various blocks were slaughtered as the initial slaught...

Five mathematical models were evaluated for their ability to describe ruminal degradability profiles of protein sources composed of herbaceous legumes, browse species and oilseed cakes. Degradability constants of dry matter, organic matter, nitrogen and neutral detergent fiber of the feeds were t...
