Concentrations ... -
The Influence of topography and vegetation canopy on the deposition of atmospheric particulates Studied with 210Pb and 137Cs soil inventory measurements
(University of Edinburgh, 2003)Naturally occurring radioactive isotopes of 210Pb and 7Be in the atmosphere, plant material and soil have been used to investigate the transport and removal of atmospheric aerosols from the atmosphere by precipitation and ... -
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. ... -
Assessment of heavy metal enrichment and degree of contamination around the copper-nickel mine in the Selebi Phikwe Region, Eastern Botswana
(Horizon Research Publishing Cooperation, 2013)This paper focuses on heavy metal (Co, Cu, Fe, Pb, Mn, Ni and Zn) enrichment and degree of contamination in the soils windward of the Selebi Phikwe copper and nickel mine (eastern Botswana). Pollution by these metals was ... -
Prediction of animal population dynamics with a focus on smallholder pig breeding establishments #
(Botswana University of Agriculture and Natural Resources, 2012)Botswana government has made efforts to diversify agriculture and pig production has been identified as one avenue to achieve this diversification in the livestock industry. It is important that farmers are encouraged to ... -
Physicochemical properties of butter made from camel milk
(Elservier, 2013)The making of butter from camel milk using a traditional churning method and the physicochemical properties of the butter were assessed. Camel milk was obtained from pastorally managed camels in the Erer valley, eastern ... -
Phosphorus levels in shoots of Bambara groundnut in Botswana soils
(Taylor & Francis, 2002)The critical phosphorus (P) concentration and range of bambara groundnut (Vigna subterranea) plants were determined from a sand culture experiment at Botswana College of Agriculture. Twelve P levels (0.207–159 mg P pot−1) ... -
Potassium→ammonium exchange of two benchmark soils from Botswana and its implication for nitrogen economy of the soils
(Taylor & Francis, 2014)Ion exchange preferences for NH4+ and K+ by soil exchanger surface can greatly affect the NO3− leaching into groundwater and nitrogen-use efficiency in agricultural production. Since NH4+ and K+ salts are usually applied ... -
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 ... -
Pastoralists’ perception and ecological knowledge on savanna ecosystem dynamics in semi-arid Botswana
(Resilience Alliance, 2012)We investigated vegetation dynamics in relation to livestock grazing as perceived by pastoral farmers in different regions of Botswana. A structured questionnaire was used to collect farmers’ understanding of vegetation ... -
Ngoro: an indigenous, sustainable and profitable soil, water and nutrient conservation system in Tanzania for sloping land
(Elservier, 2004)The Matengo people, in SW Tanzania, developed the ngoro conservation system several hundred years ago and it is a very effective indigenous manual cultivation practice for steep slopes. It deserves wider recognition and ... -
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 ... -
Limb Deformities of farmed ostrich (Struthio camelus) chicks in Botswana
(Springer, 1997)Limb deformities were detected in 135 out of 885 ostrich chicks, giving a prevalence of 15.3%. Tibiotarsal rotation a¡ected 73% of the chicks with limb deformities, whereas rolled toes accounted for 36%. The right leg was ... -
