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. ... -
Egg quality characteristics of different varieties of domesticated helmeted guinea fowl (Numida meleagris)
(Academic Journals, 2013)A study was conducted to evaluate external and internal egg quality characteristics of the pearl, lavender, royal purple and white varieties of the helmeted guinea fowl kept intensively at Botswana College of Agriculture. ... -
Chemical composition and sensory evaluation of meat of tswana hens fed different protein sources: mopane worm, bambara groundnut and morama bean
(Science-line Publishers, 2019-03-25)This study investigated the chemical composition and sensory evaluation of meat of Tswana hens fed diets containing mopane worm (Imbrasia belina, Westwood) or Bambara groundnut (Vigna subterranea (L) Verde) or morama bean ... -
Effect of weaning age on growth performance of crossbred pigs reared up to 70 kg body weight under intensive system
(Intergrity Research Journals, 2016-11-08)This study investigated the effect of weaning age on growth performance of crossbred piglets reared up to 70 kg body weight (BW) under intensive system from May to November 2013. The experiment was conducted in a completely ... -
Effect of weaning age and sex on meat quality traits of pigs raised under intensive system and slaughtered at 70 Kg body weight
(Nexus Academic Publishers, 2014-07-04)The aim of the study was to determine the effects of weaning age and sex on carcass quality of pigs slaughtered at 70 kg body weight. A total of 24 piglets were purchased at birth from a commercial farmer and were assigned ... -
Influence of stocking density on growth performance of family chicks reared up to 18 weeks of age in under an intensive system
(International Journal of Current Microbiology and Applied Sciences, 2014)The objective of the study was to evaluate the influence of stocking density on growth performance of family chicks reared up to 18 weeks of age under intensive system. A total of 248 day old chicks were randomly assigned ... -
Impact of family chickens on the livelihoods of people living with HIV and AIDS in four villages of Botswana
(Scienceline Publication, 2011)The impact of family chickens on the livelihoods of people living with HIV and AIDS (PLWHA) was investigated in Khudumelapye, Mogobane, Mokubilo and Serowe villages of Botswana. The objectives of this study were to determine ... -
Growth performance of guinea fowl fed diets containing yellow maize, millet and white sorghum as energy sources and raised under intensive system
(Asian Network for Scientific Information, 2013)This study investigated growth performance of guinea fowl fed diets containing 3 cereal grains as energy sources in comparison to commercial broiler diets. Birds were raised under intensive system from 3 to 16 weeks of ... -
Preliminary investigation of transfer of metals from soil to vegetables: Case study of Spinacia oleracea L.
(Academic Journals, 2016-09)The objective of the study was to measure concentrations of Cu, Ni and Zn in Spinacia oleracea cultivated at a site near the copper and nickel mine in Selebi Phikwe. The mean concentrations (in dry matter-basis) of Cu, Zn ... -
Investigation of heavy metal hazards Status and their potential health risks in vegetables Irrigated with treated wastewater in Oodi gardens
(Springer, 2017-10-11)This study was conducted in Oodi Village, Botswana to investigate human health risk associated with heavy metals: Mn, Fe, Cu, Ni and Zn intake via consumption of contaminated locally grown vegetable: Spinacia oleracea L. ... -
