An experiment was performed to investigate the energy efficiency and effect of poultry house size on energy productivity in 3 different capacity management systems. Capacities of houses were 10000(3 housings), 20000 (2 housings) and 28000 (1 housing) birds per production period and were assigned as HI, HII and HIII respectively. This experiment was conducted in a completely randomized design ap...

Poultry litter usage in horticultural crop production is a contributor to nuisance fly populations, in particular stable flies (Stomoxys calcitrans L.) and house flies (Musca domestica L.). Extrapolation of adult emergence data suggests that approximately 1.5 million house flies and 0.2 million stable flies are emerging on average from every hectare of poultry litter applied as a preplant ferti...

Measureable rates of genome evolution are well documented in human pathogens but are less well understood in bacterial pathogens in the wild, particularly during and after host switches. Mycoplasma gallisepticum (MG) is a pathogenic bacterium that has evolved predominantly in poultry and recently jumped to wild house finches (Carpodacus mexicanus), a common North American songbird. For the firs...

We compared the frequencies of non-synonymous, synonymous and non-protein coding SNPs in the House Finch and poultry populations by comparing three groups of SNPs. The first type were polymorphisms that likely arose in the House Finch MG lineage, as they are fixed in the poultry MG strains but are polymorphic amongst the House Finch ones. The second group are those SNPs that likely arose in the...

This study examined constraints and adoption in poultry production in the Northern Agricultural Zone of Delta State, Nigeria. A sample size of 80 respondents comprising of Supervisors of selected farms was used for the study. Data were collected through the use of a structured and validated questionnaire. Data were collected in March 2017. Descriptive statistics such as frequency count, mean sc...

While direct contact may sometimes be sufficient to allow a pathogen to jump into a new host species, in other cases fortuitously adaptive mutations that arise in the original donor host are also necessary. Viruses have been the focus of most host shift studies, so less is known about the importance of ecological versus evolutionary processes to successful bacterial host shifts. Here we tested ...

Viral and bacterial pathogens are a significant economic concern to the US broiler industry and the ecological epicenter for poultry pathogens is the mixture of bedding material, chicken excrement and feathers that comprises the litter of a poultry house. This study used high-throughput sequencing to assess the richness and diversity of poultry litter bacterial communities, and to look for conn...

Poultry are known to harbor antibiotic resistant and pathogenic bacteria, and as such poultry litter and poultry house air can be contaminated with these bacteria. However, the presence of antibiotic resistant bacteria in biological aerosols and litter is largely not understood. The purpose of this study was to determine the amount of aerosolized bacteria and endotoxin, particularly fecal indic...
