Genetic evaluation of milk yield of Bos taurus dairy breeds in Kenya
(2006-11-12)
The objective of this study was to quantify the rate of genetic progress in 305-d milk yield (MY) in Bos taurus dairy cattle breeds. The Bos taurus breeds considered were Holstein Friesian (F), Ayrshire (A), Jersey (J) and ...
Beef production in the arid and semi-arid lands of Kenya: constraints and prospects for research and development
(SAGE Publications, 2006-09)
Most of Kenya (80%) is classified as arid and semi-arid. The climatic conditions in these regions are so harsh for crops that only livestock production can thrive. These regions provide the bulk of beef consumed in the ...
Estimation of maternal covariance components for growth traits in the Sahiwal cattle
(2007)
Maternal influence on growth of artificially reared Sahiwal cattle was investigated using data from the National
Sahiwal Stud (NSS). Growth records on animals born from 1973 to 2004 were used for the analysis. The ...
Estimates of genetic Parameters for growth of Kenya Boran cattle using Random Regression models
(2006)
Data consisting of 18 884 weight records collected from 1 273 Boran cattle from birth to 24months of age were
used to estimate genetic parameters for growth of Boran cattle using random regression (RR) models under ...
Evaluation of nutritive value and palatability by goats and sheep of selected browse foliages from semiarid area of Kenya
(Blackwell Publishing Asia, 2008-08-01)
The feeding value of five browse foliages (Acacia brevispica, Acacia mellifera,
Berchemia discolor, Zizyphus mucronata and Maerua angolensis) grown in semiarid area of
Kenya were evaluated. Their chemical composition ...
Genetic evaluation of growth of Kenya Boran cattle using random regression models
(Springer Netherlands, 2007-10-01)
Data consisting of 18 884 weight records collected from 1273 Boran cattle from birth to 24 months of age were used to estimate covariance functions and genetic parameters for growth of Boran cattle using random regression ...
Direct and maternal (co) variance components and genetic parameters for growth and reproductive traits in the Boran cattle in Kenya
(Springer Netherlands, 2009-06-01)
Direct and maternal (co)variance components and genetic parameters were estimated for growth and reproductive traits in the Kenya Boran cattle fitting univariate animal models. Data consisted of records on 4502 animals ...
Genetic parameters for weaning weight of Kenyan Boran cattle accounting for direct-maternal genetic covariances
(South African Society for Animal Science, 2006)
Genetic parameters were estimated for weaning weight (WW) in Kenya Boran cattle using animal models that assumed non-zero direct-maternal genetic covariance. In addition to the direct and maternal genetic effects, maternal ...
