(AOSIS, 2016-06-13)A retrospective study covering a period of ten years (2001–2010) was conducted using postmortem meat inspection records of the Department of Veterinary Services in Gaborone to determine the prevalence of bovine fasciolosis ... -
Influence of strain and egg size on the hatchability of indigenous tswana chicken eggs
(International Journal of Livestock Research, 2013-08-29)The objectives of this study were to find the influence of strain and egg size on the hatchability of indigenous Tswana chicken (ITC) eggs. In the first part of the study, a total of 240 eggs were collected from each of ... -
Comparative growth performance of cross-bred (50% Orpington: 25% Australorp: 25% Tswana) and pure-bred tswana chickens under an Intensive Management System
(Academic Journals, 2015)Indigenous Tswana chickens are well-adapted to local environmental conditions but exhibit slow growth rate. Exotic chickens are not well-adapted to local environmental conditions but exhibit rapid growth rate and high egg ... -
Semen characteristics of purebred naked neck tswana and black australorp x naked neck tswana crossbred chickens under an intensive management system in Botswana
(American Journal of Research Communication, 2016)Evaluation of semen quality is very important before selection of breeding cocks used for artificial insemination. The aim of this study was to characterize the semen parameters of Black Australorp x naked neck Tswana ... -
Growth performance of different strains of indigenous Tswana chickens under intensive management system
(Academic Journals, 2012-04-26)Indigenous Tswana chickens are traditionally kept under free range production system and their growth performance under an intensive management system have not been evaluated. The purpose of this study was therefore to ... -
Growth performance of Australorp x Tswana crossbred chickens under an intensive management system
(Asian Network for Scientific Information, 2013)Indigenous Tswana chickens are better adapted to prevailing environmental conditions and diseases than their exotic counterparts. They however exhibit slower growth rate and less mature final weight than their exotic ... -
A critical analysis of disease-associated DNA polymorphisms in the genes of cattle, goat, sheep, and pig
(Springer Verlag, 2008-04)Genetic variations through their effects on gene expression and protein function underlie disease susceptibility in farm animal species. The variations are in the form of single nucleotide polymorphisms, deletions/insertions ... -
A critical analysis of production-associated DNA polymorphisms in the genes of cattle, goat, sheep, and pig
(Springer, 2008-09)Increasing productivity is one of the main objectives in animal production. Traditional breeding methods have led to increased gains in some traits but gains are not easily attainable in traits with low heritabilities. ... -
