An original data set of 31, 661 lactation records of Kenyan Friesian cows covering the period 1968 through 1987 was used to develop part-lactation extension factors for milk yield, and to estimate genetic parameters for production and reproductive traits. Effects of herds and year were significan...

Genetic analysis of reproductive and productive performance of Friesian cattle in Kenya. I. Genetic and phenotypic parameters
The Kenya Livestock Recording Centre progeny testing data base covering the period 1968 through 1987 was used to estimate genetic and phenotypic trends in Friesian cattle for milk yield of all lactations, first lactation milk yield, age at first calving, and calving interval. Annual genetic and p...

Hybridization between wild and domestic bovine species occurs worldwide either spontaneously or by organized crossing. We have analysed hybridization of banteng (Bos javanicus) and zebu (Bos indicus) in south-east Asian cattle using mitochondrial DNA (PCR-RFLP and sequencing), AFLP, satellite fr...

The pattern of growth and carcass composition of indigenous Ethiopian fat tailed Menz and Horro lambs were assessed through serial slaughter and carcass dissection of 147 lambs at five different growth phases. The GLM procedure of Statistical Analysis Systems Institute and allometric growth equat...

Haematological parameters were studied in 377 apparently healthy sheep comprising three indigenous breeds of Ethiopia. The effect of breed, age, gender and season on the haematological values was assessed. There was significant (P<0.01) breed difference for all erythrocytic series. Red blood cell...
A study was conducted at the Asella Station in the Arsi Region of Ethiopia to investigate the dairy performance of indigenous purebred Arsi and Friesian X Arsi crosses under different pre-partum and post-partum supplementary feeding regimes. A total of 343 first-lactation animals were involved in...

The Genetic diversity and relationship of native Siri (Bos indicus) cattle populations of Bhutan were evaluated using 20 microsatellite markers. A total of 120 Siri cattle were sampled and were grouped into four populations according to their geographical locations which were named Siri West, Sir...
