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 ... -
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. ... -
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 ... -
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 ... -
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 ... -

(Wiley, 2009-06-12)Calcium and body weight and obesity; Calcium and cardiovascular diseases; Calcium and osteoporosis; Calcium bioavailability in milk and dairy products; Calcium from milk and dairy products; Calcium, abundant mineral in ... -
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 ... -
Single nucleotide polymorphisms in ghrelin gene and the resulting genetic variants at ghrelin locus in different strains of indigenous Tswana chickens
(Academic Journals, 2012-05-12)Ghrelin is a growth hormone releasing peptide which also affects feed intake in chickens. Ghrelin is encoded by chicken ghrelin gene (cGHRL) found in chromosome 7. Single nucleotide polymorphisms (SNPs) have been reported ...
