In studies to date, analysis of livestock industries is often limited to an aggregate of statistical values, framed within broad categories such as "industrial," "semi-intensive," "backyard," or "mixed farming" production systems (Robinson et al. 2011).
Outbreaks that involve large numbers of animals are characterized by the penetration of infection into the commercial circuit; that is, industrially reared poultry and all other poultry that is traded, including those from semi-intensive and backyard farms.
Although modern commercial poultry production today is based on large farms and intensive husbandry, keeping backyard poultry has regained popularity in industrialized countries.
In addition to their long duration, agricultural fairs also enable the comingling of pigs from multiple locations and various production systems (backyard to intensive commercial) at 1 site.
England's hopes of staging the 2018 World Cup have suffered a double blow following a week of intensive lobbying in Fifa's backyard designed to have exactly the opposite effect.
* Multivariate logistic regression £ The reference category is the category when the presumed risk factor is absent Our results confirm the trend of awareness and preventive behaviour practice during a time of sporadic human avian influenza infection and after a one year intensive campaign in a small backyard poultry system between 2006-2007.
In commercial broiler farms in Vietnam, animals are typically slaughtered after 5 6 weeks, i.e. at half the age compared to animals from backyard and semi-intensive operations, just at the peak of Campylobacter infection prevalence [ 65– 65].
While "backyard" and semi-intensive production systems are still widespread, particularly in LMICs, industrial enterprises have been estimated to account for 74% of the world's poultry production, 40% of pork, and 68% of egg production (Bruinsma 2003).
Although modern commercial poultry production in industrialized countries is concentrated in large farms that practice intensive husbandry, strict biosecurity control and organized health management, raising small poultry flocks in backyards for eggs and meat has regained popularity.
The respondents comprised of individual livestock farmers having mainly backyard farms made up of heterogeneous species of animals and practicing the semi-intensive management system.
