Gastrointestinal (nematode) infections in small ruminants : epidemiology, anthelmintic efficacy and the effect of wattle tannins.
(2010)Nematode parasites have become the biggest problem for small ruminant production in South Africa due to their resistance to the commercial anthelmintics. Notable, wattle tannin has been used as an alternative strategy for ... -
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 ... -
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 ... -
Indigenous knowledge on preservation and quality of chevon.
(2017)The study was conducted to assess the indigenous methods on preservation of chevon and their effect on its quality. A case study approach was conducted in Nongoma to identify indigenous knowledge on chevon preservation and ... -
Influence of composition and storage conditions on diet quality and productivity of broiler chickens.
(2003)Two experiments were conducted to assess the effects of varying storage temperature and relative humidity (RH) on feed quality and nutritive value of such diets when fed to broiler chickens. The diets used in experiment ... -
Influence of feed bulk on physicochemical properties of digesta in pigs.
(2013)Physicochemical properties of fibre-based diets were used to determine the influence of feed bulk on physicochemical properties of digesta within each segment of the gastrointestinal tract and digesta in pigs. In the first ... -
Influence of polyethylene glycol inclusion on growth performance and serum biochemistry of growing pigs fed on Acacia tortilis leaf meal.
(2015)The broad objective of the study was to determine the influence of polyethylene glycol (PEG) in leaf meal diets on growth performance and serum biochemistry of growing pigs. Forty eight clinically healthy male F1 hybrid ... -
Influence of water salinity on growth performance and physiological responses in Nguni goats.
(2015)A survey was conducted to investigate factors influencing water scarcity for goats in areas where there are seasonal and perennial river systems in poor resource-limited smallholder communal farming systems. About 8 and ... -
Interaction of dietary protein and vitamin E supplementation on faecal egg counts, growth performance and haematological indices in lambs.
(2016)Abstract available in pdf. -
Interaction of pen enrichment and sex on growth, physiology and behavioural responses of Windsnyer pigs.
(2016)The broad objective of the study was to determine the interaction of pen enrichment and sex on growth performance, metabolite concentrations, physiological responses and behaviour of Windsnyer pigs. Forty–eight growing ... -
The interactions between maturity type and pre-feedlot plane of nutrition on the growth and performance of steers.
(1997)The growth of tissues (bone, muscle and fat), along their natural growth curve, is controlled by a complex array of interactions. Growth gradients exist between the tissues and the body as a whole, bone being earlier ... -
An investigation into growth in Jersey, Holstein and Hereford heifers on kikuyu pasture (Pennisetum clandestinum) using N-Alkanes to estimate intake and ruminal outflow rate.
(1997)The experiment was designed to investigate why dairy heifers perform poorly on kikuyu pasture compared to a beef breed like the Hereford. The main assumption was that the lower growth rate in dairy breeds was due to low ... -
An investigation of factors influencing rate of lay, egg weight and embryonic growth in broiler breeder hens.
(1998)The laying performance of broiler breeder hens is characteristically poor. Of the eggs that are produced, a large proportion are rejected before setting because they are either too small or excessively big, and of the ... -
Liver abscesses and performance in feedlot cattle as influenced by dietary roughage level and tylosin inclusion.
(2003)The focal interest of this study was the problem of liver abscesses that occurs in intensively fed beef cattle. The literature on metabolic disorders and diseases associated with feeding high concentrate diets to beef ... -
Livestock ownership by gender and seasonal impact on production : a case study at Msinga Municipality.
(2015)Research was conducted at Msinga Municipality focusing on identifying limiting factors on goat and cattle husbandry and evaluating the degree to which seasonal changes could affect goats and cattle production. Msinga ... -
The long and short term effects of Leucaena leucocephala on ram fertility.
(2000)No abstract available. -
Matching the nutritional requirements to performance in broiler breeder hens.
(1997)Quantitative food restriction during the rearing and laying period has become the standard management procedure in commercial broiler breeder operations to control the rapid growth rate of broiler breeders. This raises ... -
Meeting nutritional requirements of mature broiler breeder hens.
(2001)The overall objectives of this study were to compare the response of broiler breeder hens to dietary lysine at peak rate of lay and late in the laying cycle when rate of lay has declined, to compare the coefficients of ...
