A mixed model simultaneous procedure is described to estimate location parameters for the right-censored and uncensored traits in the practical animal breeding data set for herd-life and milk production. Location parameters of fixed effects represented by herd -year effects and random effects rep...

A method for estimating variance and covariance components for both uncensored and censored traits is described. The paper considers two cases: An uncensored trait and a right-censored trait; and two uncensored traits. A multivariate normal distribution is assumed for these traits and Bayesian ar...

Genetic diversity of sub-Saharan African goats was assessed using 19 microsatellite markers. Breeds were sampled from eastern Africa (Maasai, Kigezi, Mubende, North West Highland, Arsi Bale), southern Africa (Ndebele, Pafuri) and West Africa (West African Dwarf, Maure, Djallonke). European breeds...

The genetic diversity within indigenous livestock breeds of countries like Ethiopia results from the diverse ways in which these resources have been used to support human livelihoods and their ability to cop with the specific environments in which they have been kept. The genes and gene combinati...

The maximum likelihood parameters estimated in logistic analysis are in terms of a transformation of the original response variable and, although inferences are easily made about the sources of variation in the linearized model using standard procedures applied in regression analysis, the varianc...
