  1. Variation of oil content and fatty acid composition in selected lines of vernonia (<em>Vernonia galamensis</em> variety <em>ethiopica</em>)

    Variation of oil content and fatty acid composition in selected lines of vernonia (<em>Vernonia galamensis</em> variety <em>ethiopica</em>)

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Vernonia (Vernonia galamensis) is a new industrial crop that could offer a naturally epoxidized oil with great economic value. The oil content and fatty acid composition of 10 selected lines of V. galamensis variety ethiopica were analysed to study the...
  2. Principal agronomic and seed oil traits in the industrial oil crop vernonia (<em>Centrapalus pauciflorus</em> var. <em>ethiopica</em>)

    Principal agronomic and seed oil traits in the industrial oil crop vernonia (<em>Centrapalus pauciflorus</em> var. <em>ethiopica</em>)

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Vernonia (Centrapalus pauciflorus) is potentially a new crop that could offer naturally epoxidised industrial oil. The objective of this study was to apply principal component analyses on agronomic traits, seed oil and fatty acid compositions in vernonia to identify the...
  3. COMPARISON OF FISH GONADS AND FISH MEAL AS MAJOR COMPONENTS IN THE DIETS OF YOUNG AFRICAN SHARPTOOTH CATFISH, <em>CLARIAS GARIEPINUS</em> (BURCHELL)

    COMPARISON OF FISH GONADS AND FISH MEAL AS MAJOR COMPONENTS IN THE DIETS OF YOUNG AFRICAN SHARPTOOTH CATFISH, <em>CLARIAS GARIEPINUS</em> (BURCHELL)

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    The replacement of fish-meal (two sources, arbitrarily designated FMA and FMB), with either freeze dried (GVD) or oven dried (GOD) gonads of Clarias gariepinus in a starter diet for larvae of this species, was tested. No significant difference in larval...
  4. Liver lipids of Indian and Atlantic Ocean spinner <em>Carcharhinus brevipinna</em> and blacktip <em>Carcharhinus limbatus</em> sharks

    Liver lipids of Indian and Atlantic Ocean spinner <em>Carcharhinus brevipinna</em> and blacktip <em>Carcharhinus limbatus</em> sharks

    Item type: Journal Article • Journal: African Journal of Marine Science
    Shark liver oils are rich in polyunsaturated fatty acids, especially the n3 moieties. Data on the liver fatty acids of sharks from African waters, however, are limited. Liver samples from sharks from the western Indian Ocean off the east coast...
  5. Characterisation of the dietary relationships of two sympatric hake species, <em>Merluccius capensis</em> and <em>M. paradoxus</em>, in the northern Benguela region using fatty acid profiles

    Characterisation of the dietary relationships of two sympatric hake species, <em>Merluccius capensis</em> and <em>M. paradoxus</em>, in the northern Benguela region using fatty acid profiles

    Item type: Journal Article • Journal: African Journal of Marine Science
    The two sympatric species of Cape hake, Merluccius capensis and M. paradoxus, have been the main targets of bottom-trawl fisheries off Namibia for several decades. The feeding ecology of these hakes has been studied mainly using stomach content analyses and...
  6. Malnutrition in the acutely ill patient: is it more than just protein and energy?

    Malnutrition in the acutely ill patient: is it more than just protein and energy?

    Item type: Journal Article • Journal: South African Journal of Clinical Nutrition
    Malnutrition has traditionally been thought to involve deficiencies in protein and energy (macronutrients); however, we know that specific key nutrients, when deficient. can also lead to significant morbidity and mortality. Large studies performed with replacement of single nutrients, such as...
  7. What health professionals should know about omega-3 fatty acid supplements

    What health professionals should know about omega-3 fatty acid supplements

    Item type: Journal Article • Journal: South African Journal of Clinical Nutrition
    Omega-3 (n-3) fatty acids are essential to maintain satisfactory human health and need to be consumed in the diet. Western diets are often deficient in n-3 fatty acids because of an insufficient intake of cold water oily fish. The main...
  8. Fatty acids in beef from grain- and grass-fed cattle: the unique South African scenario

    Fatty acids in beef from grain- and grass-fed cattle: the unique South African scenario

    Item type: Journal Article • Journal: South African Journal of Clinical Nutrition
    Objective: Different fatty acids elicit different responses in the human body once ingested. Although red meat is often considered to be a source of fatty acids which has a negative impact on human health, many studies have reflected variability in...
  9. Protected nearshore shallow and deep subtidal rocky reef communities differ in their trophic diversity but not their nutritional condition

    Protected nearshore shallow and deep subtidal rocky reef communities differ in their trophic diversity but not their nutritional condition

    Item type: Journal Article • Journal: African Journal of Marine Science
    Large physical changes that alter reef macrobenthos and fish assemblages occur with increasing depth, so the biological processes that regulate communities at different depths are expected to diverge. We used analyses of stable isotopes (δ13C and δ15N) and fatty acids...
  10. Effect of nutrient calcium on the cell wall composition and digestibility of kikuyu grass (<em>Pennisetum clandestinum</em> Hochst)

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The effect of calcium in the nutrient medium on kikuyu grass (Pennisetum clandestinum Hochst), grown in a solution culture, was investigated. Calcium had no effect on the lignin content of leaf material, but decreased the lignin content per unit stem...
