Knowledge of composition of fat, protein and water in the body is indicative for the determination of effects of changes in nutrition in terms of body reserves. Deuterium oxide dilution technique has been proposed as easy, reliable and non-destructive method of determining body composition using ...

The influence of forage type, feed allowance and watering time on faeces and urine excretion by cattle, sheep and goats was studied. Higher amounts of nitrogen (N) were excreted during the day than during the night. The occurrence of defaecation and urination was highest at the time of getting up...

Published and new data from experiments conducted in several range sites in Niger and Mali were analysed to assess wet season, dry season and year-round animal weight changes, stocking rates, forage availability, feed intake and faecal excretions of cattle, sheep and goats. Herbage availability o...

Short-duration rotation grazing was compared with deferred grazing in a 3-year experiment at ICRISAT, Niger. Short-duration grazing used a mixed herd (2 steers, 4 sheep and 4 goats) and cycles of 15-21 days in the wet season and 91 days in the dry season. Wet season grazing compared high (83-126 ...

In the short term, grazing of a 40-ha fallow in the Sahel, Niger, by sheep and goats reduced the standing herbage mass in the wet season and increased its disappearance during the dry season. The effects of stocking rate (62.5 or 125 k g liveweight/ha) and the proportion of sheep in the mixture (...
