Thirty Highland zebu oxen with a mean weight of 276 (SE ± 14.3) kg and about 6 years of age were blocked by weight into 5 groups of 6 oxen each and within groups allocated to 6 treatments. They worked for 51 days followed by 84 days recovery. Teff straw (Eragrostis tef) and lablab (Lablab purpure...

This manual has been produced to standardise some analytical procedures at ILCA and among those NARS scientists who may be interested in the aspects of feed evaluation which the manual attempts to address. The first part of the manual is on determination of voluntary intake, digestion and retenti...

Study was conducted to determine turnover of water, nitrogen and energy in lactating Holstein x Boran cows. Nine cows (Bos indicus × B. taurus) between their 42nd and 420th the days of lactation were selected for this study. The crossbred cows had ad libitum access to water and a dried maize stov...

This paper deals with foraging behaviour of cattle grazing semi-arid rangelands in the Sahel of Mali. It discusses the location of study site, vegetation in the grazing orbit, herd management and livestock behaviour. Results on seasonal variation in feed supply, selection of the annual grazing or...

The macro mineral status of cattle in the Selale highlands of Ethiopia was evaluated during the rainy and dry seasons of 1989 and 1990 in terms of mineral concentrations in soils, feeds, blood plasma and faeces on 25 farms. Bone samples from animals of local breeds from a slaughter house were col...
