    This paper examined the relationship between leadership, financial management, risk manageent, governance and clean audit. The independent variables (leadership, financial management, risk manageent and governance) were extracted from the Auditor General’s reports on audit outcomes for municipalities in South Africa for the five years from 2009/10 – 2013/4, and used to determine the degree to which they are related to the achievement of clean audit outcomes. A quantitative approach (panel data regression analysis) was employed, based on a positivist paradigm, to examine the relative effects of the independent variables as key to achieving clean audit outcomes. The findings show that leadership, financial management, risk management and governance jointly have a significant relationship with clean audit outcomes, with a value of P<0,005 (which is substantially below the 5% Alpha level anticipated at the start of the research for this paper) and additionally point to the existence of a much more significant relationship between achieving a clean audit outcome and governance. The paper contributes to theory and practice. The theoretical contribution is that the independent variables (leadership, financial management, risk management,governance) need to work jointly to deliver an effective accountability and quality audit – hence futher research should examined such influence jointly and also try to add additional independent variables. The practical implication is that public sector governance may not be blamed as a single factor that causes accountability or audit issues

    Forage legumes are commonly used as an absorbent additive in high-moisture silages. Thus this study was carried out to assess the nutritive value, fermentation characteristics and aerobic stability of Opuntia–legume browse mixed silages. Five browse legume species (Leucaena leucocephala, Acacia mellifera, Searsia lancea, Prosopis velutina, and Grewia flava) were mixed with Opuntia cladodes. The silage mixture was formulated at a ratio of 60 Opuntia cladodes: 40 leguminous browse species and ensiled in polythene bags and kept in a laboratory for 42 days to determine chemical composition and fermentation characteristics. Silage samples were also subjected to an aerobic stability test. One-way analysis of variance in a completely randomised design was used to analyse the data. The pH values for silages made from Opuntia cladodes with L. leucocephala, A. mellifera and G. flava were lower than 4.8, which is considered an indicator of good-quality silage. The water-soluble carbohydrates content of silages made with Opuntia cladodes and S. lancea and G. flava was within the range of 8–12 g/kg dry matter, which is sufficient for good fermentation. The highest CO2 production, which signifies poor aerobic stability, was recorded for the control silage (Opuntia) compared to all Opuntia–legume mixed silage treatments. The addition of legume browse leaf-meal to Opuntia cladodes improved nutritive value, fermentation characteristics, and silage quality. Therefore, despite some limitations, Opuntia–legume browse silages, particularly Opuntia–G. flava and Opuntia–L. leucocephala, proved to be beneficial for livestock, as they meet the nutritional requirement of a ruminant.Significance:This study underlines the importance of co-ensiling Opuntia cladodes and high protein legume browse hay to offer an alternative feeding strategy for ruminant livestock and ensure sustainable provision of high-quality feed during dry periods

    Background and Aim: Acinetobacter baumannii and Klebsiella pneumoniae are opportunistic bacterial pathogens responsible for hospital-acquired infections in veterinary medicine. Infection with these bacteria always requires urgent antimicrobial therapy. However, there is no evidence of studies that have investigated the antimicrobial drug resistance profile of these organisms in a veterinary setting in South Africa. This study investigated the antimicrobial resistance (AMR) patterns of A. baumannii and K. pneumoniae from clinical specimens obtained from dogs presented at a veterinary academic hospital. The findings of this study contribute to an improved understanding of the AMR profile of these bacteria in veterinary medicine. Materials and Methods: Retrospective data of clinical samples from dogs that were positive for A. baumannii and K. pneumoniae between 2007 and 2013 were used in this study. The antimicrobial susceptibility of the isolates was determined using the disk diffusion method following the Clinical and Laboratory Standards Institute guidelines. The A. baumannii isolates were subjected to a panel of 20 antibiotics, while K. pneumoniae isolates were subjected to a panel of 22 antibiotics. Data were analyzed using descriptive statistics and presented using tables and figures. Results: Twenty (n = 20) A. baumannii isolates were isolated from bronchoalveolar lavage, foreign objects, bone, urine, skin, blood, ear, nasal, and oral cavity. Almost all A. baumannii (95%, 19/20) isolates were resistant to at least one antibiotic, and 60% (12/20) were multidrug-resistant (MDR). Klebsiella pneumoniae (n = 56) was isolated from urine, foreign objects, abscesses, ears, eyes, tracheal aspirations, bronchoalveolar lavages, eyes, abdominal aspirates, anal glands, bones, and intestinal and lung biopsies. All K. pneumoniae (100%, 56/56) isolates were resistant to at least one antibiotic, and 98% (55/56) were MDR. Conclusion: Both A. baumannii and K. pneumoniae were isolated in various clinical tissue samples and exhibited a high prevalence of resistance to multiple antibiotics. In addition, these bacteria exhibited a high prevalence of resistance to β-lactam compared to other classes of antibiotics, which is likely to impact treatment options and patient prognosis

    The nutritional use of millet grain for food and feed: a review

    Get PDF
    Abstract Worldwide, millets are regarded as a significant grain, however, they are the least exploited. Millet grain is abundant in nutrients and health-beneficial phenolic compounds, making it suitable as food and feed. The diverse content of nutrients and phenolic compounds present in finger and pearl millet are good indicators that the variety of millet available is important when selecting it for use as food or feed. The phenolic properties found in millets compromise phenolic acids, flavonoids, and tannins, which are beneficial to human health. Moreover, finger millet has an exceptionally unique, more abundant, and diverse phenolic profile compared to pearl millet. Research has shown that millet phenolic properties have high antioxidant activity. The presence of phytochemicals in millet grains has positive effect on human health by lowering the cholesterol and phytates in the body. The frantic demands on maize and its uses in multiple industries have merited the search for alternative grains, to ease the pressure. Substitution of maize with pearl and finger millets in the diets of different animals resulted in positive impact on the performance. Including these grains in the diet may improve health and decrease the risks of diseases. Pearl millet of 50% or more can be used in broiler diets without adversely affecting broiler performance or egg production. Of late, millet grain has been incorporated in other foods and used to make traditional beverages. Thus, the core aim of this review is to provide insight and comprehension about the nutritional and phenolic status of millets and their impact on human and livestock

    A review of the possibilities of utilising medicinal plants in improving the reproductive performance of male ruminants

    Our review condensed evidence on the potential of medicinal plants to improve the reproductive performance of livestock. The success of any livestock farming operation is highly dependent on the reproductive performance of animals. However, infertility has limited the proficiency of livestock and resulted in economic losses. For centuries, farmers utilised medicinal plants extensively in managing reproductive disorders. These plants have few to no side effects, are cheap, easily accessible and readily available. Among others, the inclusion of Moringa olifera leaf extracts for 14 days at levels of 100–300 mg/kg body weight improved sperm characteristics. Zingiber officinale root extracts at levels of 500–1000 mg/kg body weight for 3 weeks increased sperm count, viability and mobility and testosterone. Furthermore, the increase in the volume of ejaculate and sperm concentration has been observed in sheep when Leucaena spp were added to their diets at 100–300 g/sheep/day for 60 days. However, there is little literature regarding the use of medicinal plants on ruminants, as the majority of studies have been laboratory-based and have used experimental animals, including rats and mice. Thus, future research is required through in vivo and in vitro studies to ascertain the efficacy of these medicinal plants in male ruminants
