Kosgey, I.S.Werf, J.H.J. van derKinghorn, B.P.Arendonk, Johan A.M. vanBaker, R.L.[Theoretical assessment of alternative pure-breeding schemes for sheep meat in the tropics]Theoretical assessment of alternative pure-breeding schemes for sheep meat in the tropics

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...


Schlecht, E.Fernández Rivera, S.Hiernaux, Pierre H.Y.[Timing, size and nitrogen concentration of faecal and urinary excretions in cattle, sheep and goats: An they be exploited for better manuring of cropland?]Timing, size and nitrogen concentration of faecal and urinary excretions in cattle, sheep and goats: An they be exploited for better manuring of cropland?

Deals with a study in voluntary intake and livestock productivity in the Sahel carried out over a year using a herd of Zebu cattle, with some observations repeated on a flock of Sahelian sheep and goats, both under traditional management. Also presents a comparison to herds elsewhere.

Autor: Mirkena, T.

The aim of this thesis was to identify breeding objectives of smallholder and pastoral sheep keepers in Ethiopia (Afar, Bonga, Horro and Menz areas) and to design appropriate community-based breeding plans for genetic improvement of four indigenous sheep breeds. Information on genetics of adaptat...

A total of 146 Menz and Horro lambs of both sexes were serially slaughtered and dissected at 5 different stages of growth (i.e. at 1, 3, 6, 9 and 12 months of age) to define the pattern of growth and partitioning of fat among body depots of indigenous Ethiopian Menz and Horro sheep breeds. The GL...

Degradation of arid and semi-arid lands (ASALs) through denudation has been found to result in lowered capacity to support livestock, particularly under extensive production systems. After a participatory rural appraisal (PRA) in Kajiado district, an opportunity was identified in the pastoral res...

Identifies the various forms of economic loss due to ovine fascioliasis in tropical Africa; suggests a method for estimating the losses and an analytical framework for evaluating alternative management interventions; recommends that the design of biological experiments should be more comprehensiv...
