Typology of smallholder’s pig production systems in South Kivu, Democratic Republic of Congo: Challenges and opportunities
(2020-06-30)
Pig farming plays an important role in farmers’ livelihoods in many tropical countries. It contributes to food security of the poorest as well as the development of rural economy through multiplier effects. In the South Kivu province, pig farms are almost exclusively owned by smallholders. A few studies have attempted to describe thoroughly pig farming systems in this province. This study was undertaken to characterise pig production systems, in order to better understand their current situation, namely constraints ...

The potency of robusta coffee pulp as a vinegar product
(2023-11-30)
Coffee processing produces 40-50 % of by-products that can damage coffee plants and cause environmental pollution. The coffee pulp as waste can be used for producing acetic acid solution as a preservative and hand-washing agent to prevent infection. The fermentation process can affect the quality of the acetic acid solution. This study aims to analyse the effect of yeast types and time fermentation as well as to determine the characteristics of acetic acid solution from Robusta coffee pulp. The experiment consists ...

Cricket powder (Acheta domesticus) as a lean pork meat replacer in cooked sausages
(2023-08-29)
The incorporation of insects in everyday foods is a developing area. Therefore, the aim of this study was to determine the optimal percent replacement (5.0, 7.5 or 10.0%) of lean pork meat with cricket power (CP) in cooked sausages. For this purpose, the quality and safety were evaluated through the following parameters: pH, moisture, water activity, TBA value, colour (L*, a*, b*), texture and sensory profile, microbiological status and microstructure during seven-day cold storage. The pH of cooked sausages with CP ...

Land degradation and the upper hand of sustainable agricultural intensification in sub-Saharan Africa - A systematic review
(2024-05-13)
Sub-Saharan Africa (SSA) faces severe land degradation, driven by a combination of human and natural factors. Deforestation, inadequate land management practices, and unsustainable farming methods are the primary causes. The historical trends reveal the impact of soil erosion and nutrient depletion on 70% of the soil and 65% of its total land area. Unchecked degradation poses a critical threat to economic growth and poverty reduction initiatives. The region's food security is intricately linked to the complex interplay ...

Plant growth, water quality, carbon and nutrient flows in rural-urban cropping systems of Bengaluru, India
(2024)
The global urban population is expected to reach 5.2 billion by 2030 and by mid-2023 approximately 4.6 billion out of more than 8 billion population were living in towns or cities. This represents approximately 57% of the total global population and is set to reach 60% by 2030. India’s urban population is expected to reach 607 million by 2030 and by mid-2030 40% of the total population will be living in urban areas. Growing urban population has multi-sectoral and dimensional implications in the rural, peri-urban, and ...

Effect of storage conditions on soybean seed quality produced by smallholder farmers within two districts of Gauteng, South Africa
(2024-05-22)
Seed quality comprises of physical, physiological, and health attributes. Moreover, significant aspects of seed quality include seed viability and vigour. Maintaining good seed quality under sub-optimal storage conditions is one of the major challenges smallholder soybean farmers face. Hence, this study aimed to determine the effect of on-farm storage conditions on the seed quality of soybeans from smallholder farmers within the Gauteng Province, South Africa. The objectives of this study were to i) evaluate and ...

Influence of season and phytochemicals on the elemental composition of kobs’ diets in Old Oyo National Park, Nigeria
(2024-02-20)
Phytochemicals or plant secondary metabolites (PSMs) are known to counteract mineral nutrients (MNs) utilisation in herbivorous wildlife, yet studies on the interactions between PSMs and MNs in relation to herbivory, particularly for kobs (Kobus kob) are scarce. Composite samples of each of five major forage plants of kobs’ (Grewia mollis, Afzelia africana, Gardenia aqualla, Maranthes polyandra and Andropogon gayanus) were randomly collected in and around feeding sites of kobs in both dry and wet season. Using standard ...

Evaluation of efficacy of homeopathic and antibiotic treatment in scientific research and practice with focus on bovine mastitis
(2024)
The use of homeopathy and antibiotics in treatment have the same goal: to cure a diseased individual. The first choice should be the most effective treatment and only a repeated treatment success will justify its use. If the chosen treatment is not effective, unnecessary suffering of diseased animals, spreading of disease or chronification of mastitis will be the result. Additionally, in case of antibiotic use, an ineffective use will select and promote the prevalence of multi-resistant bacteria in the environment, ...
