this study was conducted to determining the gpx, hemoglobin concentration (hb) and hematocrite percentage (hct) in blood samples of young ewes were gathered at different places of zagheh salman pastures in qom province. 15 blood samples were gathered through 8 flocks during autumn, winter and spring seasons randomly. at first the measures of gpx, hb and hct were determined and then gpx concentr...

Salmonella spp. are important food borne pathogens worldwide that frequently infect poultry flocks. This cross-sectional study was conducted to determine the prevalence of Salmonella spp. colonization in broiler flocks in Shiraz (southern Iran) and to find the possible association of infection status with some potential risk factors including vaccination program and use of antibiotics. During O...

11 Resistance to anthelmintics in populations of gastrointestinal nematodes is a major concern in small ruminants. One solution to limit the spread of anthelmintic resistance is to apply treatments selectively by targeting the most susceptible animals within a flock. In dairy goats, previous studies have shown that, within a flock, goats in first lactation and those with high level of milk prod...

Salmonella Infantis is a poultry-adapted enterica serovar that increasingly reported in broilers and also regularly identified among human salmonellosis cases. An emerging S. mega-plasmid (pESI), carrying fitness, virulence antimicrobial resistance genes, found. We investigated the prevalence, genetic characteristics risk factors for (pESI-carrying) broilers. Faecal samples from 379 broiler flo...

Background Infertility is the inability to conceive children after one year of unprotected intercourse. The estimated prevalence of infertility in Canada is 11.5-15.7%. Fertility problems affect approximately one in seven couples in the United Kingdom (UK). Infertility occurs in conditions in which the pregnancies end with recurrent miscarriages (ASR) or birth of a child with multiple congenita...

Prevalences in terms of the number of eggs contaminated (internally and externally) with Salmonella Enteritidis per million are presented based on a 2 stage Bayesian model. The first stage estimates the average flock prevalence over laying period in the production system and the second stage estimates the proportion of contaminated eggs for an infected flock. These are combined to give the expe...
