Breed effects and heterosis for weight traits and tick count in a cross between an indigenous fat-tailed and a commercial sheep breed
(Springer Link, 2021-02-15)
Ticks can compromise productivity and welfare in free-ranging sheep. Chemical tick control may not be sustainable in the long term. Alternative control measures must be sought for an integrated control programme. Birth and ...
Expression of cytokine genes at tick attachment and control sites of Namaqua Afrikaner, Dorper and South African Mutton Merino sheep
(Elservier, 2021-02)
Cytokines are immune response components important in innate immunity and inflammatory response. They are harnessed as part of local immunological responses by animals to combat local infections and/or infestations. This ...

(Academic Journals, 2021-02-05)
Despite claims that Taenia saginata taeniosis/cysticercosis cause adverse financial and socioeconomic effects on cattle farmers, there is no recent empirical evidence to justify this assertion in Botswana. This paper ...
Chemical composition, in vitro dry matter digestibility and Gas production of four browse species and their combinations used as feed for small ruminants
(West African Journal of Applied Ecology, 2020)
Browse species as complete feed for ruminants is uncommon. This may be due to low dry matter (DM) and high condensed tannins (CT) contents limiting its potential to influence weight gain. Drying however improves DM content ...
Effect of substituting corn with cobs treated with combinations of urea and wood ash on chemical composition and invitro gas production substrate
(Federation for Animal Science (FAS), 2021-06-11)
This trial was aimed at determining the effect of substituting corn with cobs treated with urea (25%) and wood ash (75%) on chemical composition and gas production substrate. Corn was substituted with graded levels of ...
On-farm phenotypic characterization of indigenous Tswana sheep population in selected Districts of Southern Botswana
(Academic Journals, 2021-09-03)
This study aimed to phenotypically characterize indigenous Tswana sheep under its natural environment and develop prediction equations for body weight using linear body measurements in Kgatleng, Kweneng, Southern and ...
Chemical composition and gas production substrates of maize cobs treated with combinations of urea and wood ash
(Federation for Animal Science (FAS), 2021-06-11)
Effect of treating maize cobs with a combination of urea and wood ash (WA) on chemical composition and in vitro gas production truly degraded substrate (TDS) were examined. The treatments were:1) 100U = (100% urea and 0% ...
Growth performance of royal purple and white guinea fowl varieties and their crosses under an intensive management system
(Academic Journals, 2020-09)
Commercialization of guinea fowl production in many countries is growing and the demand for their meat is high. The study evaluated the growth of crossbred royal purple x white variety relative to purebred royal purple and ...

(Botswana University of Agriculture & Natural Resources, 2020-04-04)
Abstract: This study aimed to investigate: 1) gastrointestinal nematode (GIN) infection in goat flocks, and 2) efficacy of ivermectin treatment in three villages around Gaborone, Botswana. A 100 goats randomly selected ...
Forage conservation in sub-Saharan Africa: Review ofexperiences, challenges, and opportunities
(John Wiley & Sons, Ltd, 2021-11-11)
Forage conservation is an important potential solution to seasonal variation in feed quality and quantity and herder-farmer conflicts in sub-Saharan Africa (SSA). Considerable variations exist in the type of forages conserved ...
