Relationship between Village Chicken Availability and Dietary Diversity along a Rural-Urban Gradient.

Dietary diversity is one of the fundamental factors of nutritional security and a proxy used to measure diet quality. The objective of this study was to investigate the relationship between village chicken availability and the dietary diversity of households along a rural-urban gradient. Face-to-face interviews were conducted using a structured questionnaire in rural ( = 100), peri-urban ( = 100), and urban ( = 100) areas of Pietermaritzburg uMgungundlovu District, KwaZulu-Natal, in South Africa.

Contribution of Village Chickens in Sustainable and Healthy Food Systems for Children along a Rural-Urban Gradient: A Systematic Review.

Achieving sustainable and healthy food systems in support of human and planetary health is a global challenge. We systematically reviewed papers ( = 2322) showing how village chicken products (meat, eggs, and offal) contribute to sustainable and healthy food systems for children along a rural-urban gradient. A total of 72 articles, representing all different sections covered in this review, were finally included.

Potential of combining natural-derived antioxidants for improving broiler meat shelf-life - A review.

Synthetic antioxidants have shown adverse effects on consumers. The review, thus, aims to assess the effect of marinating broiler meat with plant leaves-derived antioxidants potential for improving shelf-life and human health. Broiler meat loss and waste due to spoilage is more than three million kg annually, thus, extending shelf-life by reducing initial microbial load and autoxidation is essential.

A food systems approach and qualitative system dynamics model to reveal policy issues within the commercial broiler chicken system in South Africa.

Global broiler production and consumption levels continue to rise. South Africa's broiler system is dominated by commercial production and formal retail trade, with competition from cheap imports. Local broiler policies have narrow, production-driven, short-term aims for industry growth and national food security.

Do water shortages increase gastrointestinal nematode loads in Nguni does?

Objective: The objective of the study was to assess the effects of water deprivation on the burden of gastrointestinal nematodes in Nguni does.

Methods: A survey was piloted on goat keepers in households where water was scarce (n = 143) and where it was available throughout the year (n = 142). In a controlled experiment, feed intake (ADFI), body condition score (BCS), FAMACHA score, packed cell volume (PCV) and faecal egg counts (FEC) were determined in does deprived of water for 24 and 48 h.

Characterisation of the indigenous knowledge used for gastrointestinal nematode control in smallholder farming areas of KwaZulu-Natal Province, South Africa.

Methods: A structured questionnaire was used to collect data from farmers.

WITHDRAWN: Responses in apparent total digestibility, rate of passage, growth performance and physicochemical properties of the digesta of Windsnyer pigs fed on increasing levels of potato hash silage.

Differences in burden of gastrointestinal nematode infestations in indigenous does foraging in grassland and forestland vegetation types.

Gastrointestinal nematode (GIN) infestations remain a major challenge to the health, productivity and reproductive performance of small ruminants. A longitudinal study was conducted to assess the effect of vegetation type, season and parity on the burden of GIN in indigenous does that were foraging in grassland and forestland vegetation types. Body condition scores (BCS), packed cell volume (PCV), FAMACHA score and faecal egg counts (FEC) were determined in Xhosa lob-eared does (n = 165) during the cool-dry, hot-wet and post-rainy seasons in both vegetation types.

A Qualitative Analysis of the Commercial Broiler System, and the Links to Consumers' Nutrition and Health, and to Environmental Sustainability: A South African Case Study.

Food systems face growing challenges to meet targets of Zero Hunger (SDG 2), and South Africa is no exception given its triple burden of malnutrition, foodborne disease outbreaks, and threats of climate change to food production. Broiler meat is South Africa's most affordable meat option, supporting household food and nutrition security. Although considered healthier and less environmentally harmful than ruminant meat, it is not without food safety risks and environmental impacts.

Indigenous Slaughter Techniques: Effects on Meat Physico-Chemical Characteristics of Nguni Goats.

To improve goat meat quality in rural communities, it is important to evaluate the effects of indigenous slaughter methods used by resource-limited farmers when performing traditional ceremonies on the meat physico-chemical characteristics. The current study assessed the effects of the meat physico-chemical characteristics of Nguni goats slaughtered with the transverse neck incision (TNI), suprasternal notch piercing (SNP) and the under shoulder blade piercing at the chest floor point of elbow (CFP) to the direction of the heart methods. Thirty Nguni weathers were randomly assigned to three slaughter treatments (10 goats/treatment).

Growth performance and fertility of Windsnyer boars supplemented with α-tocopherol.

The purpose of the present work was to determine the response in growth performance and spermatozoa characteristics of Windsnyer boars supplemented with progressive levels of α-tocopherol. Twenty Windsnyer boars aged 12 weeks with an average body weight of 19.5 ± 2.

Response to reduced dietary protein level on growth performance in growing Windsnyer pigs.

The objective of the study was to determine the growth performance response to reduced dietary protein level and to identify the optimum level of protein for the performance in growing Windsnyer pigs. Maize-soybean-based diets were formulated to contain a protein level of 193 g/kg, 173.7 g/kg, 154.

A systems analysis and conceptual system dynamics model of the livestock-derived food system in South Africa: A tool for policy guidance.

Global food production systems are currently under scrutiny, in particular the health, nutrition, and environmental impacts of livestock-derived food (LDF). Despite South Africa's recent socio-economic transformation and increased per-capita LDF consumption, the triple burden of malnutrition persists. Policy responses to such complex problems often fail because of linear thinking with short-term goals.

Attitudes and practices of resource-limited farmers on the control of gastrointestinal nematodes in goats foraging in grasslands and forestlands.

Gastrointestinal nematode infestations remain one of the main constraints to goat productivity. A cross-sectional survey was conducted to investigate the perceptions of goat farmers on the infestation and control of gastrointestinal nematode infestation. A total of 282 goat farmers from two villages of Mbizana local municipality in Alfred Nzo district were interviewed.

Mitigating the effects of drought on cattle production in communal rangelands of Zimbabwe.

The objective of the study was to examine strategies employed by farmers to mitigate the effects of drought on cattle production in communal rangelands of Zimbabwe. Data were collected from a total of 316 communal cattle farming households selected from semi-arid and sub-humid environments (158 each) using structured questionnaires. Farmers in sub-humid environments mostly resorted to controlled migration in search of pastures during drought whilst those in semi-arid environments mainly supplemented their cattle (P < 0.

The objective of the study was to compare factors influencing water scarcity for goats in areas where there are seasonal and perennial rivers under resource-limited communal farming environments. Data were collected using a structured questionnaire (n = 285) administered randomly to smallholder goat farmers from areas with seasonal and perennial rivers. Ceremonies was ranked as the major reason for keeping goats.

Effects of environmental enrichment on behaviour, physiology and performance of pigs - A review.

This paper aims to critically analyse and synthesise existing knowledge concerning the use of environmental enrichment and its effect on behavior, physiology and performance of pigs housed in intensive production systems. The objective is also to provide clarity as to what constitutes successful enrichment and recommend when and how enrichment should be used. Environmental enrichment is usually understood as an attempt to improve animal welfare and to a lesser extent, performance.
