Comparison of genetic and immunological responses to tick infestation between three breeds of sheep in South Africa
(University of the Free State, 2016-01)The study investigated genetic parameters and immunological responses to tick infestation in three South African sheep breeds (Namaqua Afrikaner [NA], Dorper and SA Mutton Merino [SAMM]). The study aimed to estimate genetic ... -
Comparison of Laboratory pH Buffer Methods for Predicting Lime Requirement for Acidic Soils of Eastern Botswana
(Taylor & Francis, 2004)The suitability of pH buffer methods that determine lime requirement (L.R.) of acid soils of the eastern region of Botswana has not been determined, and the soil physiochemical properties that influence L.R. are not known. ... -
Condensed tannins from Botswanan forage plants are effective priming agents of γδ T cells in ruminants.
(Elsevier, 2012-03-05)The potential impact of extracts from forage plants on y8 T cell activity in ruminants was evaluated using an in vitro immunoassay. This study investigated whether plant extracts could prime y8 T cells via up-regulation ... -
Conservation implications of brown hyaena (Parahyaena brunnea) population densities and distribution across landscapes in Botswana.
(Sabinet, 2017-08-16)The brown hyaena (Parahyaena brunnea) is endemic to southern Africa. The largest population of this near-threatened species occurs in Botswana, but limited data were available to assess distribution and density. Our ... -
Contribution of red alder to soil nitrogen input in a silvopastoral system
(Springer-Verlag, 2007-01-11)Studies on Alnus rubra Bong. (red alder) were carried out to assess its potential for use as a component of a silvopastoral system. Comparison was between two treatments: red alder at 400 stems ha−1 (silvopasture) and red ... -
