Application of metabolomics to identify functional metabolic changes associated with Haliotis midae growth
(North-West University, 2018)The South African abalone, "perlemoen" (as it is called locally) industry is largely based on farming with Haliotis midae, which has been commercially cultured in man-made shore-based systems with great success for the ... -
Assessment of growth performance, haemo-biochemistry and meat quality of Japanese quails fed on Moringa oleifera
(North-West University (South Africa), 2019)The use of readily available, non-conventional feed resources in quail farming has the potential to sustainably improve animal protein supply in resource-poor communities in South Africa. Moringa oleifera leaf meal is one ... -
The effect of magnetic water on macadamia plants' physiology and phenological characteristics
(North-West University (South Africa), 2019)The biggest obstacle in the macadamia industry is both slow germination and growth rates. Several research studies have been conducted on magnetized water and its effect on plant growth. Magnetizing water can increase the ... -
Effects of Bt crop residues on the development, growth, and reproduction of the freshwater snail, Bulinus tropicus
(North-West University, 2014)Genetically modified (GM) crops were introduced in South Africa in 1989 and commercially available by 1998. Legislation to control the use of GM crops was only implemented in 1999, with the genetically modified organisms ... -
Effects of increased heat and drought stress approximating climate warming on the reproduction, photosynthesis and growth of Proteaceae species in a southern African Mediterranean climate ecosystem
(North-West University (South Africa), Potchefstroom Campus, 2016)In this research project, the effects of warming and drought on three Proteaceae species (Protea repens, Protea laurifolia, Leucadendron laureolum) were investigated through various monitoring and experimental studies on ... -
Effects of the invasive annual grass Lolium multiflorum Lam. on the growth and physiology of a Southern African Mediterranean-climate geophyte Tritonia crocata (L.) Ker. Gawl. under different resource conditions
(North-West University, 2007)Little is known of the physiological and biochemical mechanisms underlying competitive interactions between alien invasive grasses and native taxa, and how these are affected by resource supply. Consequently, this study ... -
Humic acid and enzymes inclusion in Canola-Based Broiler Diets : effects on physiological and meat quality parameters
(North-West University (South Africa), 2017)This study was undertaken to investigate the effects of potassium humate and Axtra XAP enzyme (Xylanase + Amylase + Protease) as dietary additives on growth performance, protein utilisation efficiency, blood parameters, ... -
Insect meal (Hermetia illucens) as an alternative protein source for Jumbo quails : physiological and meat quality traits
(North-West University (South Africa), 2019)Globally, soybean (Glycine max) meal is used as a standard vegetable protein source for poultry feeds. However, due to the negative ecological impact of soybean production, alternative natural and inexpensive protein ... -
Physiological responses and meat quality of Potchefstroom koekoek cockerels offered canola meal as an alternative to soybean meal
(North-West University (South Africa), 2018)The current study was conducted to assess growth performance, protein utilisation efficiency, blood parameters, meat quality, bone breaking strength, density and mineral composition of Potchefstroom Koekoek (PK) cockerels ... -
Urban and rural growth modelling : from theory to practice
(North-West University (South Africa), 2018)Cities are considered complex systems (Batty, 2008). It consists of numerous interactive sub-systems and is affected by diverse factors including government land policies, population growth, transportation infrastructure, ...
