Integration of indigenous knowledge systems in sustaining water security for cattle in resource-limited communities.
(2021)The broad objective of the study was to assess the integration of indigenous knowledge systems in sustaining water security for cattle production in resource-limited communities. Cattle production in resource-limited ... -
Perceptions of consumers, retailers and their attitude towards rabbit meat in the KZN province, South Africa.
(2021)The broad objective of the current study was to determine the response and attitudes of consumers and retailers towards rabbit meat. Growth performance and the quality of rabbit meat as influenced by breed were also ... -
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 ... -
Response in nitrogen balance, fibre digestibility and physicochemical characteristics of digesta in Windsnyer pigs fed on incremental levels of amarula nut cake.
(2021)The broad objective of the study was to determine the response in nitrogen balance, fibre digestibility and physicochemical characteristics of digesta in slow-growing Windsnyer pigs fed on incremental levels of amarula ... -
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 ... -
Nature and level of trace mineral premix supplementation on growth parameters and mineral excretion in commercial broiler rations.
(2018)Commercial broiler premixes provide trace minerals (TM) such as Zinc (Zn), Manganese (Mn) and Copper (Cu) in excess of the birds’ requirements to maximize broiler performance (Untea et al., 2011). High inclusion levels of ... -
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 ... -
In vitro fermentation and growth performance of merino lambs fed on umbrella thorn (Vachellia tortilis) leaf meal and sunflower oil.
(2019)Forage legumes and vegetable oils are supplemented in ruminant diets to improve nutrient quality (energy density and crude protein content) and mitigating rumen gaseous emissions. The effects of both forage legumes and ... -
In vitro assessment of selected ethno-medicinal plants as potential alternatives for the control of gastrointestinal nematodes in sheep and goats.
(2018)Commercial anthelmintics are becoming ineffective against gastrointestinal nematodes (GIN) of ruminants due to development of resistant parasites. Research is exploiting anthelmintic ethno-medicinal plants for an alternative ... -
Response in antioxidant activity and shelf life of meat from broilers fed on incremental levels of Vachellia tortilis leaf meal.
(2018)The broad objective of the study was to determine the antioxidant activity and shelf life of meat from boilers fed on incremental levels of Vachellia tortilis leaf meal. One hundred and twenty Cobb-500-day old unsexed ... -
Use of indigenous methods to control gastro-intestinal nematodes in chickens.
(2018)Millions of resource-limited farmers depend on indigenous knowledge (IK) to sustain chicken health. The level of understanding on these IK systems is low. The objectives of the study were to: (1) explore IK used to control ... -
Effects of water availability on physiological status of Nguni does and weaners.
(2018)Physiological status of goats is mainly affected by the availability of feed and water. Factors such as frequency of droughts and low rainfalls are main contributors to water scarcity. Understanding perceptions of goat ... -
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, ... -
Effects of essential oil, probiotic, palm kernel fatty acid distillate, optigut, or sunflower whole seeds as alternatives to antibiotic growth promoters on broiler performance.
(2019)The increasing consumer and legislation pressure to phase out the antibiotic growth promoters (AGPs) in the broiler industry has prompted researchers to find suitable alternatives to AGPs that will improve broiler performance ... -
Use of inert markers to predict diet composition, forage intake, digestibility and passage rate in sheep.
(2019)The mechanisms that regulate intake and composition of selected diets in ruminants are complex and vary among animals of the same species and cross species. These are governed by highly variable aspects, which range from ... -
Selenium × zinc interaction on growth performance, carcass traits and semen quality of Large White × Landrace and Kolbroek boars.
(2018)Abstract available in PDF. -
Response in carcass yield, organ weights and the gut morphology to Vachellia tortilis inclusion in broilers.
(2018)The broad objective of this study was to determine the response to incremental levels of Vachellia tortilis leaf meal on carcass yield, organ weights and gut morphology of broilers. Five-hundred unsexed cobb 500-day-old ... -
Distribution, phenotype and factors influencing the production potential of Nguni sheep.
(2018)The Nguni sheep of South Africa is an indigenous breed that is adapted to its environment. Migrating from Central Africa down the sweltering east coast of Africa down to Southern Africa, the sheep were exposed to different ...
