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 ... -
Cutaneous hypersensitivity reactions against unfed tick larval extract of Rhipicephalus evertsi in South African Mutton Merino, Namaqua Afrikaner and Dorper sheep
(Elsevier:, 2018-07-23)Indigenous Namaqua Afrikaner (NA) sheep have been reported to be more resistant to tick infestation than the commercial Dorper and South African Mutton Merino (SAMM) breeds. The aim of this study was to compare cutaneous ... -
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 ... -
Indigenous Tswana pig production characteristics and management practices in southern districts of Botswana
(Springer, 2019-02-14)Indigenous animal genetic resources are vital in agriculture especially in the era of climate change because they are adapted to the harsh local conditions. Therefore, their conservation through utilisation is necessary. ... -
Performance of Tswana pigs with traditional management in SE-Botswana
(Journal of Agriculture in the Tropics and Subtropics, 2000)The performance of Tswana pigs was studied under tmditional management systems. Tswana pigs performed poorer than other indigenous African pigs in reproduction and growth traitscxcept in survival ratc. ln general, indigenous ... -
Milk production of Tswana goats fed diets containing different levels of energy
(South African Society of Animal Sciences, 2000)The aim of this experiment was to characterize the milk yield of the Tswana goat of Botswana. Twenty-one Tswana goat does were allocated to one of three diets formulated to provide energy for maintenance and a milk yield ... -
