Utilisation of indigenous knowledge to mitigate challenges of gastrointestinal nematodes in goats.
(2021)Gastrointestinal nematodes (GIN) constitute a huge challenge to goat productivity worldwide, leading to production losses. Anthelmintic drugs have been used to control GIN, but their effectiveness has been reduced due ... -
Modelling of feeding behaviour, rumen load and the kinetics of digestion and passage of digesta in domestic and wild ruminants.
(2021)Roughage intake is affected by a collection of factors that include feeding behaviour, and the weight of rumen digesta which is a function of digesta clearance from the rumen as governed by the rates of degradation and ... -
Exploring the use of indigenous knowledge to mitigate tick challenges in goats.
(2020)Farmers in developing countries with limited access to orthodox veterinary care commonly use indigenous knowledge. Indigenous knowledge (IK) stems out of peoples' ingenuity, credulity and long insatiable curiosity of the ... -
Genetic diversity and differentiation of pelt, mutton and wool sheep breeds of South Africa using genome-wide single nucleotide polymorphisms.
(2021)Sheep, Ovis aries, are a versatile species that has, over hundreds of years, been adapted to South African environmental conditions resulting in more than 40 breeds that are raised for various objectives and production ... -
Effects of selected medicinal plant extracts on bacterial activity, cytotoxicity, rumen fermentation, nutrient utilization, and methane mitigation.
(2021)This research was conducted to address two important areas of global interest in livestock production: (i) the contribution of ruminants to climate change through the emission of methane gas produced in the rumen during ... -
Behaviour, physiological responses, meat yield and gut morphology of free-range chickens raised in a hot environment.
(2016)It is vital to minimise thermal stress and associated welfare problems for birds reared in hot environments and behaviour is a good indicator of thermal stress. The broad objective of the study was to investigate behavioural, ... -

Plant-plant combination: an important option in the phase of failing anthelmintics to control nematodes in small ruminants.
(2018)The present study was designed to explore how combination phytoanthelmintic therapy can be employed to enhance livestock nematode control in goats and sheep. This was motivated by wide spread emergence of resistant varieties ... -
Influence of physical state of farm housing and processing facilities on quality and safety of dairy milk products.
(2018)The broad objective of the study was to determine the influence of physical state of farm housing and milk processing facilities on the quality and safety of milk and its products. Data collected from urban areas (n =135) ... -

Influence of water stress on feed intake, growth performance and nutritional status of Nguni goats.
(2016)The broad objective of the study was to determine the influence of water stress (water deprivation, water restriction and water salinity) on feed intake, growth performance and the nutritional status of Nguni does. A ... -
Ecological benefits of brachiaria grasses in integrated crop-livestock production systems in Rwanda.
(2016)A study was conducted with the broad objective to evaluate ecological benefits of Brachiaria grasses in integrated crop-stall-fed livestock production systems in humid and semi-arid region of Rwanda. The specific objectives ... -
Relationship between linear type traits and fertility in Nguni cows.
(2014)The broad objective of the study was to determine the relationship between linear type traits and fertility in Nguni cow herds. Data collected from 300 Nguni cattle owning households from two municipalities (150 each) were ... -
Improving the nutritive value and utilisation of non-conventional protein feed resources in smallholder village chicken production systems.
(2014)Poultry production is one of the most important activities for creating wealth in developing countries. This study was conducted to assess methods of improving the nutritive value and utilization of cowpeas, and ameliorating ...
