This paper investigates preferences for cattle traits among a pastoral community in a trypanosomosis prevalent area in Kenya. Choice experiments and mixed logit models are employed to estimate economic values of preferred traits which could be introduced through systematic breeding in breed impro...

Methods for biodiversity conservation are reported and applied to 49 African cattle breeds (26 taurine/sanga and 23 zebu/zenga (ZZ) breeds). It was estimated that about half of the breeds and half of today’s genetic diversity between breeds would be lost within 50 years. Based on a survey and a l...

The diversity of animal genetic resources has a quasi-public good nature that makes market prices inadequate indicator of its economic worth. Applying the characteristics theory of value, this research estimated the relative economic worth of the attributes of cattle genetic resources in central ...
