“…Organically produced foods are much more rigorously regulated with requirements in place for all aspects of production and processing while natural poultry and other meats are only regulated from a post-processing side (1). Pasture raised poultry, when considered within a broad category, is defined as a production system where birds are raised outdoors in some sort of small, moveable, ventilated pen arrangement (16, 30, 31). Management of these pens in terms of frequency of rotation in a pasture, protection from predators, types of housing, and other requirements are described in detail by Fanatico (32).…”

“…Management of these pens in terms of frequency of rotation in a pasture, protection from predators, types of housing, and other requirements are described in detail by Fanatico (32). Housing can either be moveable or fixed with portable housing being easily moved without causing injury to the birds (16, 30). Given the diverse nature of these types of practices, several potential challenges exist for achieving consistent production levels to meet market demands over a period of time.…”

While most of the focus on poultry microbiome research has been directed toward conventional poultry production, there is increasing interest in characterizing microbial populations originating from alternative or non-conventional poultry production. This is in part due to the growing general popularity in locally produced foods and more specifically the attractiveness of free-range or pasture raised poultry. Most of the focus of microbiome characterization in pasture flock birds has been on live bird production, primarily on the gastrointestinal tract. Interest in environmental impacts on production responses and management strategies have been key factors for comparative microbiome studies. This has important ramifications since these birds are not only raised under different conditions, but the grower cycle can be longer and in some cases slower growing breeds used. The impact of different feed additives is also of interest with some microbiome-based studies having examined the effect of feeding these additives to birds grown under pasture flock conditions. In the future, microbiome research approaches offer unique opportunities to develop better live bird management strategies and design optimal feed additive approaches for pasture flock poultry production systems.

“…Carriers for Salmonella during the conventional poultry production cycle can include a wide variety of sources including rodents and cats as well as insects which when present in poultry houses can serve as infected or mechanical carriers and potential sources of this pathogen to susceptible birds [5,8,90,91]. Less conventional poultry production facilities such as organic, pasture, or free range raised poultry where birds have more outdoor exposure represent potential contact with an even wider range of vectors and environmental sources [92,93]. In addition to Salmonella vectors, environmental transmission routes (aerosols, water) and reservoirs such as litter and feed play a key role in this dissemination.…”

Salmonellosis in the United States is one of the most costly foodborne diseases. Given thatSalmonellacan originate from a wide variety of environments, reduction of this organism at all stages of poultry production is critical.Salmonellaspecies can encounter various environmental stress conditions which can dramatically influence their survival and colonization. Current knowledge ofSalmonellaspecies metabolism and physiology in relation to colonization is traditionally based on studies conducted primarily with tissue culture and animal infection models. Consequently, while there is some information about environmental signals that controlSalmonellagrowth and colonization, much still remains unknown. Genetic tools for comprehensive functional genomic analysis ofSalmonellaoffer new opportunities for not only achieving a better understanding ofSalmonellapathogens but also designing more effective intervention strategies. Now the function(s) of each single gene in theSalmonellagenome can be directly assessed and previously unknown genetic factors that are required forSalmonellagrowth and survival in the poultry production cycle can be elucidated. In particular, delineating the host-pathogen relationships involvingSalmonellais becoming very helpful for identifying optimal targeted gene mutagenesis strategies to generate improved vaccine strains. This represents an opportunity for development of novel vaccine approaches for limitingSalmonellaestablishment in early phases of poultry production. In this review, an overview ofSalmonellaissues in poultry, a general description of functional genomic technologies, and their specific application to poultry vaccine developments are discussed.

“…Suddenly, the small farmer-based agriculture systems have once again emerged in the commercial public sector as interest has increased in locally grown food markets. Most aspects of food safety research, economics and environmental impacts have been extensively examined in the scientific literature on other emerging poultry trends in developed countries such as organic poultry production and processing (Castellini et al, 2006;O'Bryan et al, 2008;Crandall et al, 2009;Sirsat et al, 2009;Boggia et al, 2010;Gifford and Bernard, 2011;Petkar et al, 2011;Ricke et al, 2012;Van Loo et al, 2012a;2012b;2012c). However, in some regions of the United States the production capabilities have grown much faster than the capacity to effectively process such birds for consistent retail sales (Van Loo et al, 2013b).…”
