The sustainability of future poultry production needs to be improved in order to meet global challenges. The global chicken population has expanded significantly in recent decades, due to increased human demand for eggs and chicken meat. Therefore, it is critically important to mitigate challenges to the sustainability of modern poultry production, such as pollution, the depletion of finite natural resources and animal welfare issues. This study systematically mapped the scientific literature on farm-level sustainability in egg and chicken meat production. The concept of sustainability was considered holistically, covering its economic, environmental and social dimensions, each consisting of a broad range of different aspects that may contradict or reinforce each other. The literature published between January 2000 and March 2020 with a geographical focus on Europe, North America and Australia–New Zealand, were included. The literature search resulted in a total of 428 hits, but after the exclusion of articles that did not match the scope of the study, only 26 papers remained for the systematic mapping. Of these, only three papers covered all three dimensions of sustainability. Aspects of economic sustainability were addressed in 10 papers, aspects of environmental sustainability in 18 papers, and aspects of social sustainability in 23 papers. The findings in this study are an important foundation for the discussion and prioritisation of future actions to increase knowledge of farm-level sustainability in egg and chicken meat production.

The sustainability of future finfish aquaculture needs to be improved to meet global environmental challenges. Global fish aquaculture production has expanded significantly recently, due to the increased demand for fish for human consumption. Therefore, it is important to mitigate challenges to the sustainability of the sector, such as pollution and depletion of natural resources. In this study, we systematically mapped the scientific literature on farm-level sustainability in fish aquaculture. The concept of sustainability was considered holistically, covering its economic, environmental and social dimensions, each consisting of a range of different aspects that may contradict or reinforce each other. Literature published between January 2000 and August 2020 with the geographical focus on Europe, Northern America and Australia–New Zealand was included. The search resulted in a total of 287 hits, but after the exclusion of articles that did not match the scope, only 17 papers remained for the systematic mapping. Of these, five papers covered all three dimensions of sustainability. Economic sustainability was addressed in 10 papers, environmental sustainability in 13 papers and social sustainability in 12 papers. This systematic mapping provides an important foundation for discussions and prioritisations of future actions to increase knowledge on farm-level sustainability in finfish aquaculture.

We systematically mapped the scientific literature on the sustainability of pig production at farm-level. Sustainability was considered holistically, covering its economic, environmental, and social dimensions, each consisting of a broad range of different aspects that may contradict or reinforce each other. Literature published between January 2000 and March 2020 with a geographical focus on Europe, North America, Australia, and New Zealand was included. A standard template with predefined keywords was used to summarise aspects of each sustainability dimension covered in identified papers. We found that papers analysing environmental sustainability were more frequent than papers analysing economic or social sustainability. However, there are many different aspects within each dimension of sustainability, hampering comparisons between studies. In addition, each dimension of sustainability has many sides, making it difficult to compare different studies, and different dimensions and aspects may have complex interrelations. Our systematic literature review revealed that these interrelations are not well understood and that possible trade-offs or synergies between different aspects of sustainability dimensions remain unidentified. This systematic mapping of the current literature on farm-level sustainability in pig production can support a more informed discussion on knowledge gaps and help prioritise future research at farm-level to enhance sustainability in pig production.

Abstract In the context of an expanding, export-dependent agri-food sector, indicators of sustainable development and intensification are necessary to measure, assess and verify the comparative advantage afforded by Ireland’s natural pastoral-based food production systems. Such indicators are also necessary to ensure that we produce more food with less adverse impacts on the Irish environment, climate and society. This article outlines the development of farm-level indicators that refect the multifaceted nature of sustainability, which is encompassed in economic, environmental and social indicators. The role of innovation in farm sustainability was also examined. A comparison of indicators across Irish farm systems showed that dairy farms, followed by tillage farms, tended to be the most economically and socially sustainable farm systems. In relation to greenhouse gas emissions in particular, the top-performing dairy farms, in an economic sense, also tended to be the best-performing farms from an environmental sustainability perspective. This trend was also evident in relation to the adoption of innovative practices on farm, which was found to be strongly correlated with economic performance.

Background: New chicken breeds are being evolved for backyard rural poultry production to overcome the slow growth, late sexual maturity and poor production of indigenous breeds. However, autochthonous poultry is epitomized for quality attributes of their products. With this in mind, the present study for the first time explored the antioxidant capacity of meat obtained from a unique Indian chicken, Kadaknath and a synthetic breed of poultry, Jabalpur colour (JBC). Methods: During the period 2018-2020, breast and thigh meat were collected from chickens (n=20/ group) at their commercial slaughter age (20 weeks). Meat extract was used for qualitative evaluation. Antioxidant activity was explored using five well established in vitro methods testing for different antioxidant mechanisms. Result: Both, Kadaknath and JBC meat was proteinaceous with higher protein concentration (g/100 g of wet weight) in the breast (Kadaknath, 25.21±0.31 and JBC, 25.65±0.39) than the thigh (Kadaknath, 19.98±0.29 and JBC, 19.04±0.23). Both the groups exhibited antioxidant capacity in all the assays. They showed good radical scavenging for ABTS and DPPH free radicals. Superiority of Kadaknath meat was ascertained unequivocally by the three assays viz. Ferric reducing antioxidant power (FRAP), lipid oxidation inhibition (TBARS) and metal chelating capacity. FRAP values (mM Fe2+/g of tissue) were 26.97±0.37 and 33.85±0.47 (Kadaknath) and 22.84±0.25 and 26.82±0.36 (JBC) for breast and thigh, respectively. Similarly, Kadaknath meat was more potent (% inhibition) iron chelator (breast, 62.71±0.99 and thigh, 75.07±0.98) in comparison to the JBC (breast, 46.30±2.36 and thigh, 63.12±1.87). Breast meat had better scavenging capacity than the thigh except in FRAP and metal chelating assays. Results provide insight into the antioxidant potential of backyard poultry germplasm thus, laying foundation for developing marketing strategies targeting consumers interested in nutritional quality, animal welfare and environmental sustainability. Furthermore, baseline data has been generated for studying medicinal properties attributed to the black chicken meat of Kadaknath.

The review presents results of recent life cycle assessment studies aiming to quantify and improve the environmental performance of UK poultry production systems, including broiler meat, egg and turkey meat production. Although poultry production has been found to be relatively environmentally friendly compared with the production of other livestock commodities, it still contributes to environmental impacts, such as global warming, eutrophication and acidification. Amongst different sub-processes, feed production and transport contributes about 70 % to the global warming potential of poultry systems, whereas manure management contributes about 40–60 % to their eutrophication potential and acidification potential, respectively. All these impacts can be reduced by improving the feed efficiency, either by changing the birds through genetic selection or by making the feed more digestible (e.g. by using additives such as enzymes). However, although genetic selection has the potential to reduce the resources needed for broiler production (including feed consumption), the changing need of certain feed ingredients, most notably protein sources as a result of changes in bird requirements may limit the benefits of this strategy. The use of alternative feed ingredients, such as locally grown protein crops and agricultural by-products, as a replacement of South American grown soya, can potentially also lead to improvements in several environmental impact categories, as long as such feeding strategies have no negative effect on bird performance. Other management options, such as improving poultry housing and new strategies for manure management have also the potential to further improve the environmental sustainability of the poultry industries in Europe.

A produção nacional de frango de corte tem se destacado entre os demais setores produtivos nas últimas décadas. O exponencial desempenho do setor possibilitou ao Brasil assumir posição de destaque no ranking mundial, como o maior exportador e terceiro maior produtor de carne de frango.  Apesar de todos os estados brasileiros produzirem carne de frango, a produção está concentrada na Região Sul do País, sendo o Paraná o principal produtor e exportador de aves do País. Nesse cenário, o objetivo principal deste trabalho foi analisar a especialização da produção de frango de corte, através do Quociente Locacional (QL) e analisar as exportações por meio do Market-Share (MS).  Os principais resultados obtidos apontam que o avanço da tecnologia na produção, melhoramento dos índices de conversão alimentar, genética, entre outros, contribuíram para a evolução do setor, tanto em termos de produção quanto em exportação. Neste sentido a região Sul é a mais desenvolvida e especializada neste segmento. O sistema de contrato de integração facilitou o elo entre produtores rurais e agroindústria, com o fornecimento da matéria-prima e assistência técnica, e o produtor com a mão de obra e estrutura necessária. ABSTRACT The national production of broiler chicken has been outstanding among the other productive sectors in the last decades. The exponential performance of the sector enabled Brazil to take a leading position in the world ranking, as the largest exporter and third largest producer of chicken meat. Although all Brazilian states produce chicken meat, production is concentrated in the Southern Region of the country, with Paraná being the main producer and exporter of poultry in the country. In this scenario, this article had as main objective the analysis of the evolution of the poultry production in Brazil from 1995 to 2015, for that the analysis of the specialization of the production of broiler chicken was made through the Locational Quotient (QL) and the analysis of the productive concentration of the exports was made through Market-Share (MS). The main results obtained indicate that the advances in technology in production, improvement of feed conversion, genetic indexes, among others, contributed to the evolution of the sector, both in terms of production and exports. In this sense, the South region is the most developed and specialized in this segment. The integration contract system facilitated the link between rural producers and agribusiness, with the supply of raw material and technical assistance, and the producer with the necessary manpower and structure. KEYWORDS: Poultry industry. Production Specialization. Export of chicken meat.

The Right

The demand for poultry meat, being cheaper than red meat, will drive worldwide production of this product. Accordingly, an increase in production up to 16% is expected in 2025, most of which will occur in developing countries. Most poultry meat production is realized with intensive production systems, and extensive rearing systems (ERS) of poultry (organic, free-range, and low-input) represent only a small portion of poultry production in the EU (about 5%). However, there is an increasing interest in such rearing systems to maintain the good image of product and environmental sustainability, improved animal welfare, and meat quality with an annual trend of growth of about 10%. The aims of this work were to summarize the activities and the viewpoint of the researchers of the Department of Agricultural, Food, and Environmental Science of the University of Perugia (Italy). One of the most important goals of the research unit was the challenge of identifying the best poultry genotypes for ERS, which are important not only for the food industry but also for the improvement of human nutrition. Only the definition of the best genotypes adapted to ERS through the measurement of a wide panel of traits—genetic, physiologic, and behavior—and not only relying on daily weight gain will allow us to achieve this goal.

AbstractThe prime purpose of this review is to explore the pathways whereby progress towards reduced-crude protein (CP) diets and sustainable chicken-meat production may be best achieved. Reduced-CP broiler diets have the potential to attenuate environmental pollution from nitrogen and ammonia emissions; moreover, they have the capacity to diminish the global chicken-meat industry’s dependence on soybean meal to tangible extents. The variable impacts of reduced-CP broiler diets on apparent amino acid digestibility coefficients are addressed. The more accurate identification of amino acid requirements for broiler chickens offered reduced-CP diets is essential as this would diminish amino acid imbalances and the deamination of surplus amino acids. Deamination of amino acids increases the synthesis and excretion of uric acid for which there is a requirement for glycine, this emphasises the value of so-called “non-essential” amino acids. Starch digestive dynamics and their possible impact of glucose on pancreatic secretions of insulin are discussed, although the functions of insulin in avian species require clarification. Maize is probably a superior feed grain to wheat as the basis of reduced-CP diets; if so, the identification of the underlying reasons for this difference should be instructive. Moderating increases in starch concentrations and condensing dietary starch:protein ratios in reduced-CP diets may prove to be advantageous as expanding ratios appear to be aligned to inferior broiler performance. Threonine is specifically examined because elevated free threonine plasma concentrations in birds offered reduced-CP diets may be indicative of compromised performance. If progress in these directions can be realised, then the prospects of reduced-CP diets contributing to sustainable chicken-meat production are promising.

Sustainable development was defined by the UN in 1987 as development that meets the needs of the present without compromising the ability of future generations to meet their own needs, and this is a core concept in this paper. This work acknowledges the three dimensions of sustainability, i.e., economic, social, and environmental, but its focus is on this last one. A digital twin (DT) is frequently described as a physical entity with a virtual counterpart, and the data, connections between the two, implying the existence of connectors and blocks for efficient and effective data communication. This paper provides a meta systematic literature review (SLR) (i.e., an SLR of SLRs) regarding the sustainability requirements of DT-based systems. Numerous papers on the subject of DT were also selected because they cited the analyzed SLRs and were considered relevant to the purposes of this research. From the selection and analysis of 29 papers, several limitations and challenges were identified: the perceived benefits of DTs are not clearly understood; DTs across the product life cycle or the DT life cycle are not sufficiently studied; it is not clear how DTs can contribute to reducing costs or supporting decision-making; technical implementation of DTs must be improved and better integrated in the context of the IoT; the level of fidelity of DTs is not entirely evaluated in terms of their parameters, accuracy, and level of abstraction; and the ownership of data stored within DTs should be better understood. Furthermore, from our research, it was not possible to find a paper discussing DTs only in regard to environmental sustainability.
