RESUMO

Increasing intensification in swine production has led to new and specialized technologies, but the occupational health and safety impacts are rarely quantified in the business plans for adoption. Needle-less injection has potential to increase productivity and eliminate needle stick injury in workers, but it is not clear whether these benefits offset high capital investment and potential increases in musculoskeletal loads. This economic evaluation employed probabilistic scenario analysis using injury, cost, and production data gathered from interviews with swine producers in Manitoba and Saskatchewan. After adoption of needle-less injection, rates of needle-stick injury went down with no measureable effect on upper limb musculoskeletal disorders, resulting in lower health and safety costs for needle-less injectors. Needle-less injection duration was 40% faster once workers acclimatized, but large start-up costs mean economic benefits are realized only after the first year. The incremental benefit cost ratio promoted adoption of needle-less injectors over conventional needles for the base case of a 1200 sow barn; the conventional method is beneficial for barns with 600 sows or less. Findings indicate that well-designed technologies have the potential to achieve the dual ergonomics goals of enhancing human wellbeing and system performance. We anticipate that the economic and decision models developed in this study can be applied to other new technologies in agriculture and animal production.

RESUMO

Innovations supporting a shift towards more sustainable food systems can be developed within the dominant food system regime or in alternative niches. No study has compared the challenges faced in each context. This paper, based on an analysis of 25 cases of European innovations that support crop diversification, explores the extent to which barriers to crop diversification can be related to the proximity of innovation settings with dominant food systems. Drawing on a qualitative analysis of interviews and participatory brainstorming, we highlight 46 different barriers to crop diversification across the cases, at different levels: production; downstream operations from farm to retailing, marketing and consumers; and contracts and coordination between actors. To characterise the diversity of innovation strategies at food system level, we introduce the concept of "food system innovation settings" combining: (i) the type of innovative practice promoted at farm level; (ii) the type of value chain supporting that innovation; and (iii) the type of agriculture involved (organic or conventional). Through a multiple correspondence analysis, we show different patterns of barriers to crop diversification according to three ideal-types of food system innovation settings: (i) "Changing from within", where longer rotations are fostered on conventional farms involved in commodity supply chains; (ii) "Building outside", where crop diversification integrates intercropping on organic farms involved in local supply chains; and (iii) "Playing horizontal", where actors promote alternative crop diversification strategies-either strictly speaking horizontal at spatial level (e.g. strip cropping) or socially horizontal (arrangement between farmers)-without directly challenging the vertical organisation of dominant value chains. We recommend designing targeted research and policy actions according to the food systems they seek to develop. We then discuss further development of our approach to analyse barriers faced in intermediate and hybrid food system configurations.

RESUMO

Objetivou-se verificar a viabilidade econômica da produção de frangos de corte sob mecanismos de governança híbrida e hierárquica. Estudos de caso foram escolhidos para avaliação da atividade em núcleos de empresas integradoras e de produtores rurais integrados. Realizou-se pesquisa de campo para coleta de dados em 36 unidades de produção em Minas Gerais. Informações provenientes de 216 lotes produzidos entre agosto de 2015 e agosto de 2016 foram utilizadas nas análises econômicas. O cálculo dos custos baseou-se na metodologia proposta pela Embrapa - CNPSA e IEA - SP. As análises econômicas se realizaram conforme proposto pelo DAE - Ufla e pela Conab. Constatou-se que o custo com mão de obra causou maior impacto sobre o desempenho econômico de núcleos com estruturas de governança distintas. No modelo de produção via governança hierárquica, mesmo se considerando receitas secundárias ao processo de produção de aves, verificou-se prejuízo financeiro na atividade. Concluiu-se que a estrutura de governança híbrida representou melhor alternativa econômica que a internalização do processo de criação de frangos pelas empresas integradoras. Assim, sugere-se que empresas integradoras esgotem as possibilidades de produção via contrato de integração antes de investirem recursos em instalações próprias de criação.(AU)


The objective was to verify the economic feasibility in the production of broilers under hybrid and hierarchical governance mechanisms. Case studies were used to evaluate the activity of the integrating company and the integrated rural producers. The primary data about costs, income, and zootechnical indicators were collected in 36 poultry production units belonging to an integrated company and five rural producers, in state of Minas Gerais. Data from 216 batches of broilers produced between August 2015 and August 2016 were used in the economic analysis. Costs calculation was based on the methodology proposed by EMBRAPA - CNPSA and IEA - SP. The economic analyzes were carried out as proposed by DAE UFLA and CONAB. It was verified that the cost of labor caused the greatest impact on the economic performance of cores with different governance structures. In all breeding sites via hierarchical governance, even considering secondary revenues, there was a financial loss in the activity. It was concluded that the hybrid governance represented a better economic alternative than the internalization of the broiler production by integrating companies. Thus, it is suggested that integrating companies deplete the production possibilities through an integration contract before investing resources in their own breeding facilities.(AU)

RESUMO

Maternal stressors that affect fetal development result in "developmental programming," which is associated with increased risk of various chronic pathologic conditions in the offspring, including metabolic syndrome; growth abnormalities; and reproductive, immune, behavioral, or cognitive dysfunction that can persist throughout their lifetime and even across subsequent generations. Developmental programming thus can lead to poor health, reduced longevity, and reduced productivity. Current research aims to develop management and therapeutic strategies to optimize fetal growth and development and thereby overcome the negative consequences of developmental programming, leading to improved health, longevity, and productivity of offspring.

RESUMO

Recently, concerns have been raised about the possibility of Acinetobacter baumannii transmission between animals and humans. So far, A. baumannii has been reported in animals with which people can come into contact. The presence of this pathogen in animal manure presents an equally important public health risk. In this study, we report the finding of two A. baumannii isolates in swine manure from a Croatian pig farm. Both isolates shared features with the widespread human clinical isolates: affiliation to the international clonal lineage 2 (ST-195), carbapenem, and extensive drug resistance and the plasmid-located acquired blaOXA-23 gene. These two A. baumannii isolates survived anaerobic conditions, competition with other microorganisms, and elevated concentrations of heavy metals in the stagnant swine manure for at least 2 weeks. These findings call for bacteriological analysis and disinfection of liquid swine manure before its application as a fertilizer in traditional extensive agriculture.

RESUMO

Small fish species, such as zebrafish and medaka, are increasingly gaining popularity in basic research and disease modeling as a useful alternative to rodent model organisms. However, the tracking options for fish within a facility are rather limited. In this study, we present an aquatic species tracking database, Zebrabase, developed in our zebrafish research and breeding facility that represents a practical and scalable solution and an intuitive platform for scientists, fish managers, and caretakers, in both small and large facilities. Zebrabase is a scalable, cross-platform fish tracking database developed especially for fish research facilities. Nevertheless, this platform can be easily adapted for a wide variety of aquatic model organisms housed in tanks. It provides sophisticated tracking, reporting, and management functions that help keep animal-related records well organized, including a QR code functionality for tank labeling. The implementation of various user roles ensures a functional hierarchy and customized access to specific functions and data. In addition, Zebrabase makes it easy to personalize rooms and racks, and its advanced statistics and reporting options make it an excellent tool for creating periodic reports of animal usage and productivity. Communication between the facility and the researchers can be streamlined by the database functions. Finally, Zebrabase also features an interactive breeding history and a smart interface with advanced visualizations and intuitive color coding that accelerate the processes.

RESUMO

This study aimed to characterize a commercial lamb finishing system using animals of undefined breed from production to slaughter by analyzing performance, carcass traits, yield of commercial cuts, and the quality and meat acceptance of different slaughter groups, as to evaluate whether this system provides the market with a standardized product. The lots were not homogeneous for yield of commercial cuts and performance and morphometric traits evaluated in vivo. The groups were heterogeneous to 75% of the 13 carcass traits evaluated, among them, hot and cold carcass weights, hot and cold carcass yields, carcass grade finishing and biological yield. There was also no uniformity for the proportion of non-carcass components, morphometry of carcass, visual appraisals, and loin traits. On the other hand, homogeneity was achieved in physico-chemical and sensory traits, except for hardness and proportion of saturated, monounsaturated and polyunsaturated fatty acids. We conclude that the commercial finishing system with the use of undefined crossbred lambs does not produce carcass and cuts standardized to the market.

RESUMO

An individual's infectious disease risks, and hence the individual's incentives for risk mitigation, may be influenced by others' risk management choices. If so, then there will be strategic interactions among individuals, whereby each makes his or her own risk management decisions based, at least in part, on the expected decisions of others. Prior work has shown that multiple equilibria could arise in this setting, with one equilibrium being a coordination failure in which individuals make too few investments in protection. However, these results are largely based on simplified models involving a single management choice and fixed prices that may influence risk management incentives. Relaxing these assumptions, we find strategic interactions influence, and are influenced by, choices involving multiple management options and market price effects. In particular, we find these features can reduce or eliminate concerns about multiple equilibria and coordination failure. This has important policy implications relative to simpler models.

RESUMO

An agent-based computer model that builds representative regional U.S. hog production networks was developed and employed to assess the potential impact of the ongoing trend towards increased producer specialization upon network-level resilience to catastrophic disease outbreaks. Empirical analyses suggest that the spatial distribution and connectivity patterns of contact networks often predict epidemic spreading dynamics. Our model heuristically generates realistic systems composed of hog producer, feed mill, and slaughter plant agents. Network edges are added during each run as agents exchange livestock and feed. The heuristics governing agents' contact patterns account for factors including their industry roles, physical proximities, and the age of their livestock. In each run, an infection is introduced, and may spread according to probabilities associated with the various modes of contact. For each of three treatments-defined by one-phase, two-phase, and three-phase production systems-a parameter variation experiment examines the impact of the spatial density of producer agents in the system upon the length and size of disease outbreaks. Resulting data show phase transitions whereby, above some density threshold, systemic outbreaks become possible, echoing findings from percolation theory. Data analysis reveals that multi-phase production systems are vulnerable to catastrophic outbreaks at lower spatial densities, have more abrupt percolation transitions, and are characterized by less-predictable outbreak scales and durations. Key differences in network-level metrics shed light on these results, suggesting that the absence of potentially-bridging producer-producer edges may be largely responsible for the superior disease resilience of single-phase "farrow to finish" production systems.

RESUMO

Near real-time epidemic forecasting approaches are needed to respond to the increasing number of infectious disease outbreaks. In this paper, we retrospectively assess the performance of simple phenomenological models that incorporate early sub-exponential growth dynamics to generate short-term forecasts of the 2001 foot-and-mouth disease epidemic in the UK. For this purpose, we employed the generalized-growth model (GGM) for pre-peak predictions and the generalized-Richards model (GRM) for post-peak predictions. The epidemic exhibits a growth-decelerating pattern as the relative growth rate declines inversely with time. The uncertainty of the parameter estimates [Formula: see text] narrows down and becomes more precise using an increasing amount of data of the epidemic growth phase. Indeed, using only the first 10-15 days of the epidemic, the scaling of growth parameter (p) displays wide uncertainty with the confidence interval for p ranging from values ~ 0.5 to 1.0, indicating that less than 15 epidemic days of data are not sufficient to discriminate between sub-exponential (i.e., p < 1) and exponential growth dynamics (i.e., p = 1). By contrast, using 20, 25, or 30 days of epidemic data, it is possible to recover estimates of p around 0.6 and the confidence interval is substantially below the exponential growth regime. Local and national bans on the movement of livestock and a nationwide cull of infected and contiguous premises likely contributed to the decelerating trajectory of the epidemic. The GGM and GRM provided useful 10-day forecasts of the epidemic before and after the peak of the epidemic, respectively. Short-term forecasts improved as the model was calibrated with an increasing length of the epidemic growth phase. Phenomenological models incorporating generalized-growth dynamics are useful tools to generate short-term forecasts of epidemic growth in near real time, particularly in the context of limited epidemiological data as well as information about transmission mechanisms and the effects of control interventions.

RESUMO

OBJECTIVES: Agriculture is one of the most hazardous industries in the United States. Within agriculture, livestock handling is particularly dangerous. While injury and fatality rates for bison handlers have not been reported, workers in many of the newly established tribal bison herds have limited safety training and animal handling experience, making this a vulnerable workforce. Veterinarians and herd managers, working with tribal bison herds, recognized the need for improvement in the working environment and for worker safety training. In response, partnerships were established and a pilot project was developed in order to characterize risks and hazards associated with bison handling under contemporary reservation field conditions. Individuals and organizations working as change agents included veterinarians at the University of Nebraska - Lincoln School of Veterinary Medicine, a tribal advocacy organization, the Intertribal Buffalo Council and researchers at the Central States Center for Agricultural Safety and Health at the University of Nebraska Medical Center. METHODS: This is a mixed-methods study and data were gathered through closed and open-ended questions pertaining to bison worker safety hazards. A veterinarian gathered data through observational safety audits at bison herding locations. American Indian bison herd managers completed surveys using a convenience sampling method. RESULTS: Findings indicate that the most common worker safety risks are associated with the use of high-stress handling methods and substandard facilities and equipment. Adverse environmental conditions also contribute to worker health risks. Most common causes of injuries included those caused by equipment and tools, adverse weather, and direct contact with animals. CONCLUSION: This collaborative research study contributes to a better understanding of hazards faced by tribal bison workers. Findings from this research influenced the ITBC in their decision to add worker safety and health training to the agenda of their yearly conference and promote tailgate trainings for their workers. UNL veterinarians have taken the lessons learned from this research and provided safety and health information to mangers of other non-tribal bison herds. This research partnership will continue with a 5-year research study focusing on best management practices and establishing training to improve the health and safety bison workers.

RESUMO

Farm animal genetic resources are threatened worldwide. Participation in markets, while representing a crucial way out of poverty for many smallholders, affects genetic management choices with associated sustainability concerns. This paper proposes a contextualized study of the interactions between markets and animal genetic resources management, in the case of sheep markets in Ouagadougou, Burkina Faso. It focusses on the organization of marketing chains and the valuation of genetic characteristics by value chain actors. Marketing chain characterization was tackled through semi-structured interviews with 25 exporters and 15 butchers, both specialized in sheep. Moreover, revealed preference methods were applied to analyse the impact of animals' attributes on market pricing. Data were collected from 338 transactions during three different periods: Eid al-Adha, Christmas and New Year period, and a neutral period. The neutral period is understood as a period not close to any event likely to influence the demand for sheep. The results show that physical characteristics such as live weight, height at withers and coat colour have a strong influence on the animals' prices. Live weight has also had an increasing marginal impact on price. The different markets (local butcher, feasts, export market, sacrifices) represent distinct demands for genetic characteristics, entailing interesting consequences for animal genetic resource management. Any breeding programme should therefore take this diversity into account to allow this sector to contribute better to a sustainable development of the country.

RESUMO

Here the authors report the objective veterinary clinical measurement of productivity in a representative south Indian Malabari goat herd. The authors show failure to meet pragmatic production targets that are commensurate with the animals' genetic potential or adequate to meet the demands of global food security. The authors suggest that this situation may have arisen as a consequence of animal husbandry constraints and protein undernutrition and imply the involvement of nematode parasitism. Benzimidazole resistance was detected in Haemonchus species, showing the need for better understanding of the principles of sustainable helminth parasite control within the southern Indian context. This study highlights the need to understand the true costs of goat production in seasonally resource-poor environments, while also considering its impact on the overall ecosystem in which the animals are placed. They conclude that pragmatic opportunities for improvements in goat production efficiency lie in the development of problem-focused planned animal health and nutrition management.

RESUMO

The amphibian model Xenopus, has been used extensively over the past century to study multiple aspects of cell and developmental biology. Xenopus offers advantages of a non-mammalian system, including high fecundity, external development, and simple housing requirements, with additional advantages of large embryos, highly conserved developmental processes, and close evolutionary relationship to higher vertebrates. There are two main species of Xenopus used in biomedical research, Xenopus laevis and Xenopus tropicalis; the common perception is that both species are excellent models for embryological and cell biological studies, but only Xenopus tropicalis is useful as a genetic model. The recent completion of the Xenopus laevis genome sequence combined with implementation of genome editing tools, such as TALENs (transcription activator-like effector nucleases) and CRISPR-Cas (clustered regularly interspaced short palindromic repeats-CRISPR associated nucleases), greatly facilitates the use of both Xenopus laevis and Xenopus tropicalis for understanding gene function in development and disease. In this paper, we review recent advances made in Xenopus laevis and Xenopus tropicalis with TALENs and CRISPR-Cas and discuss the various approaches that have been used to generate knockout and knock-in animals in both species. These advances show that both Xenopus species are useful for genetic approaches and in particular counters the notion that Xenopus laevis is not amenable to genetic manipulations.

RESUMO

This study investigated the prevalence of self-reported musculoskeletal discomfort (MSD) and work-related factors associated with elevated MSD among Latino thoroughbred farm workers. Participants (N = 225) were recruited using a community-based purposive sampling approach to participate in in-person interviews. Of these workers, 85% experienced MSD. MSD was divided into tertiles; the upper tertile was defined as elevated. Multivariable Poisson regression revealed associations between any elevated MSD and longer tenure on horse farms, longer work hours, and poor safety climate. Elevated neck/back MSD was associated with longer tenure, longer work hours, and poor safety climate. Elevated upper extremity MSD was associated with age and poor safety climate. Elevated lower extremity MSD was associated with longer tenure, longer work hours, and being female. Musculoskeletal discomfort is common among these workers. Improving safety climate and minimizing long work hours is recommended.
