Pure Nigerian Dwarf sheep (NDS) ewes were randomly assigned to rams of four breeds – NDS, Permer (p), Uda (U) and yankasa (Y). The mating periods were arranged so that lambings occurred either douring the early rainy season (ERS) or the early dry season (FDS). The lambs resulting from the matings...

Meat production is the most important trait in the breeding objectives of sheep production in East Africa. The aim of this study was to investigate breed differences in live weight, conformation, carcass traits and economic values for meat production among Red Maasai and Dorper sheep and their cr...

The Mong Cai pig is an indigenous breed and popularly raised as maternal line in northern Vietnam. In this study, the complete mitochondrial genome sequence of the Mong Cai pig is reported. The total length of this mitochondrial genome is 16 632bp, including 1 non-coding control region (D-loop re...

Sheep has successfully adapted to the extreme high-altitude Himalayan region. To identify genes underlying such adaptation, we genotyped genome-wide single nucleotide polymorphisms (SNPs) of four major sheep breeds living at different altitudes in Nepal and downloaded SNP array data from addition...

A comparative study of age at first calving in European and zebu cattle. Various influencing factors, and their effects on other productivity parameters are described. Lack of optimum feeding and management are constraints to reducing age at first calving. There is the need to reduce this in zebu...

Carcass characters for 365 male castrated cattle of the Africander, Angoni, Barotse and Boran breeds, and the reciprocal crossbreds of the latter three were reported. In each of the two year-of-birth groups, different slaughter-age/management regimes were used. For all carcass characters except t...

Live weights from birth to 3.5 years are reported for beef cattle reared under ranching conditions in Zambia. The 809 cattle were purebred Africanders, Angonis, Barotses and Improved Borans and the reciprocal crossbreds of the latter three breeds born in 2 years. All animals born in the 1st year ...

Dam reproductive performance of purebred Africander, Angoni, Barotse and Boran, and reciprocal crossbreds of the latter 3 breeds under ranching conditions were investigated. Mean performance based on a maximum of 1996 records collected over six parities were: calving rate, 65.6%; weaning weight r...
