Optimization of diet (ensiled brewer's grain) in pigs ration using a one way Manova
(School of Mathematics, University of Nairobi, 2003)A Strategy for optimising ensiled brewer's grains in ration on post-weaning, growing and finishing pig's diet is considered. The problem that relates to animal diet management varies enormously depending on objective. ... -
Effect of organic binders (corchorus olitorius and abelmoschus esculentus) on the fracture behaviour of kaolin refractories
(2005)Both the okra and "mrenda" binders were separately prepared from vegetables by boiling in water and sieving to get the filtrate. The chemical compositions of the binders were analyzed to determine both the organic and ... -
Mycorrhizal fungi associated with Kenyan terrestrial orchids and their role in orchid seed germination
(College of biological and physical sciences faculty of science department of botany University of Nairobi, 1997)Terrestrial orchids are threatened with extinction due to loss of their habitat.
