(Botswana University of Agriculture and Natural resources, 2013)This study was carried out to investigate effects of various chemicals added to vase solutions and also effects of water quality on the post-harvest physiology of Lisianthus (Eustoma grandiflorum L.) cut stems. The vase ... -
Evaluation of carcass, organ and organoleptic properties of spent layers of different poultry types.
(Botswana University of Agriculture and Natural resources, 2013)This study was designed to assess carcass, organ and organoleptic properties of spent layers of different poultry species; comprising of geese, local chicken, commercial chicken and quails. Eight (8) birds of each species ... -
Effects of substituting rice flour as fillers for wheat flour at varying levels in beef sausage production.
(Botswana University of Agriculture and Natural resources, 2012)To derive optimum benefits from agricultural products is to add value to these products. In the meat industry, sausage making is a well known process of adding value to what could otherwise be considered low quality meats ... -
Rotavirus and Cryptosporidium infection in bovine calves in Southern Botswana.
(Botswana University of Agriculture and Natural resources, 2012)A cross-sectional study on prevalences of Rotavirus (RV) and Cryptosporidium parvum infections was carried out in dairy and beef calves in 31 farms over a 2-year period. Enzyme immunoassay (EIA) was to determine RV and C. ... -
The effects of cattle-goat mixed grazing on steer performance and rangeland condition in semi-arid north eastern Botswana #

The influence of management systems on rangeland conditions under different environments in Botswana #
(Botswana University of Agriculture and Natural resources, 2012)The present study investigated rangeland conditions in communally grazed lands and ranches in different parts of semiarid Botswana. Soils and vegetation assessments were carried out along 23 transects randomly located in ... -
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 ... -
The geographical prevalence and potential epidemiology of heartwater in Botswana: implications for planning control under climate change #
(Botswana University of Agriculture and Natural resources, 2012)Heartwater caused by Ehrlichia ruminantium is a widespread animal health problem in Botswana. Although long known to be endemic, its current distribution and possible future occurrence in new areas within the country ... -
