C-reactive protein (CRP) is an inflammatory protein released by the body in response to infection and injury. Elevation of this serum protein has been linked to increased risks of heart disease through inflammation that is believed to play a key role in the hardening of arteries resulting in a heart attack or stroke. Consequently, CRP could serve as a genetic marker for an eminent cardiac event...

The objective of this study was to describe two clinical cases of toxicosis by accidental administration of salinomycin in feed in broiler breeders and turkeys. In the first clinical case, a 32000 broiler breeders flock, 30 weeks of age, suffered a severe mortality during the first week, a sharp decrease in egg production and a dramatic reduction in food consumption together with an increase of...

Domestication is a type of experimental evolution in which humans have artificially selected for specific desired traits. Selected strain animals can be utilized to identify correlated responses by comparing them to the wild strain. In particular, domestic turkeys have been selected for increased body mass and high-growth rate, most significantly over the past 60 years. Yet it remains unclear h...

Campylobacter is a leading cause of food-borne illness in the United States. Recent evidence has demonstrated that bacteriocins produced by Bacillus circulans and Paenibacillus polymyxa reduce cecal Campylobacter colonization in broiler chickens infected with Campylobacter jejuni. As Campylobacter coli is the most prevalent Campylobacter isolate recovered in turkeys, the objectives of the prese...

We conducted an observational study to estimate prevalence and risk factors for Salmonella spp. and Campylobacter spp. caecal colonization in poultry. Eighty-one broiler chicken and 59 turkey flocks selected among flocks slaughtered in the province of Quebec, Canada, were included in the study. Flock status was evaluated by culturing pooled caecal contents from about 30 birds per flock. Exposur...

Avian paramyxoviruses (APMV) are divided into nine serotypes. Newcastle disease virus (APMV-1) is the most extensively characterized, while relatively little information is available for the other APMV serotypes. In the present study, we examined the pathogenicity of two divergent strains of APMV-3, Netherlands and Wisconsin, in (i) 9-day-old embryonated chicken eggs, (ii) 1-day-old specific pa...

The objectives of this research were to evaluate the effects of thermal panting in domestic turkeys on arterial blood values for the acid-base variables, pH(a), bicarbonate concentration ([HCO(-) (3)](a)), partial pressure of carbon dioxide (P(a)CO(2)), and hemoglobin concentration [Hb]. In addition, body temperature and partial pressure of oxygen (P(a)O(2)) were measured to determine the effec...

• Turkeys were effectively colonized by Salmonella without detectable clinical signs. elicited immune-activating transcriptome responses in turkey leukocytes. impacted the STAT3 pathway, toll-like receptors, and cytokine signaling. IL1B was predicted as a major regulator of inflammatory gene expression. Non-typhoidal is one most common causes bacterial foodborne disease consumption contaminated...

Most avian influenza (AI) vaccination and field studies have focused on chickens and turkeys because of their high death rates and the large amounts of highly pathogenic avian influenza (HPAI) virus that they excrete into the environment when infected. Data on vaccination of other species against HPAI remain limited. An increasing number of studies have been conducted to test the efficacy of in...

PPROXIMATELY 17% of the eggs laid by non-mated Beltsville Small A White (BSW) turkeys showed some type (e.g., membranes, blood, embryos) of development upon incubation ( OLSEN and MARSDEN 1953,1954). The question arose as to whether the cells in such unfertilized eggs were haploid or diploid. YAO and OLSEN (1955) reported finding diploid chromosome numbers in embryonic tissue of parthenogenetic...
