Introduction: Requirements for dietary amino acids (AA) in broilers may be affected by a variety of nutritional, environmental, genetic, or management factors. In order to address these variations in diet formulation, ideal ratios of indispensible AA to digestible (d) Lys, which remain relatively unaffected by these factors, may be used instead [1]. Nutritionists have successfully applied the i...

This study sought to assess mitochondrial DNA (mtDNA) diversity and phylogeographic structure of chickens from five agro-ecological zones of Zimbabwe. Furthermore, chickens from Zimbabwe were compared with populations from other geographical regions (Malawi, Sudan and Germany) and other management systems (broiler and layer purebred lines). Finally, haplotypes of these animals were aligned to c...

The measurement of feed efficiency in the broiler industry is one of pri­ mary measurements used to monitor and evaluate broiler performance. It has a significant impact on the competitiveness in the marketplace as nearly 70% of the cost of raising a commercial broiler is feed. Although feed costs may shift up or down, it will always represent the highest input cost in commercial poultry produc...

The introduction and survival of zoonotic bacterial pathogens in poultry farming have been linked to bacterial association with free-living protozoa. To date, however, no information is available on the persistence of protozoan communities in these environments across consecutive rearing cycles and how it is affected by farm- and habitat-specific characteristics and management strategies. We th...

We report the spread of a clone of multidrug-resistant (MDR), ESBL-producing (blaCTX-M-1) Salmonella enterica subsp. enterica serovar Infantis, in the Italian broiler chicken industry and along the food-chain. This was first detected in Italy in 2011 and led to human infection in Italy in 2013-2014.A set (n = 49) of extended-spectrum cephalosporin (ESC)-resistant (R) isolates of S. Infantis (20...

The reuse of poultry litter is a common practice in the Brazilian poultry industry for flocks of healthy chickens, due to 2 fundamental aspects: production cost and environmental sustainability. Litter is a potentially important source of infection for Salmonella, which requires characterization by microbiological analysis in different aspects of management and reuse. The objective of this stud...

limited information exists on mortality rates and it’s causes on iranian broiler farms. in the present study, mortality rate, etiology and risk factors associated with mortality rate in broiler flocks, were evaluated.178 folders related to the mortality of broilers which were covered by the national insurance program for broilers in mashhad, from 21 march 2011 to 20 march 2012, were investigate...

Campylobacter and antimicrobial-resistant Campylobacter are frequently isolated from broiler chickens worldwide. In Canada, campylobacteriosis is the third leading cause of enteric disease and the regional emergence of ciprofloxacin-resistant Campylobacter in broiler chickens has raised a public health concern. This study aimed to identify, critically appraise, and synthesize literature on sour...
