Frequent vaccination failures have occurred in the broiler farms in Eurasian countries during Newcastle disease outbreaks. The disease is enzootic in many countries of the region, especially in southwest Asia. I-2 vaccine has been used successfully in village chickens in many Asian and African countries. Our preliminary study showed good efficacy of the vaccine in broiler chickens. Therefore th...

Infectious bronchitis virus (IBV) is one of the most important threats of the poultry industry worldwide including Egypt. It is usually associated with high morbidity and mortality among the affected bird flocks. All ages and breeds of chickens are susceptible to IBV infection. Commercial chickens are highly susceptible to IBV moreover, Baladi chickens can also be infected with IBV and develop ...

Domestic broiler chickens rapidly accumulate fat and are naturally hyperglycemic and insulin resistant, making them an attractive model for studies of human obesity. We previously demonstrated that short-term (5 h) fasting rapidly upregulates pathways of fatty acid oxidation in broiler chickens and proposed that activation of these pathways may promote leanness. The objective of the current stu...

Hansson, I. 2007. Bacteriological and Epidemiological Studies of Campylobacter spp. in Swedish Broilers Doctoral dissertation ISSN 1652-6880, ISBN 978-91-576-7362-6 Campylobacter jejuni is the most frequently reported cause of bacterial gastrointestinal illness in humans in Sweden. Chicken products are considered an important risk factor for human infection. This thesis analyses and identifies ...

This study was conducted to find the effect of methionine and threonine supplementations higher than the NRC recommendation on growth performance and white blood cell differentiation of broiler chickens challenged with infectious bursal disease. A total of 450 day-old male broiler chicks were assigned to nine groups. Chickens were fed by three graded levels of DLmethionine [NRC (M1), 2 times NR...

This study examined the influence of early atmospheric ammonia exposure, light intensity throughout rearing, and their interaction on blood gases, electrolytes, and acid-base balance in broiler chickens under environmentally controlled conditions. The experiment consisted of a 3 x 3 factorial arranged in a randomized complete block design, with trials being replicated over time. The 9 treatment...

DENEV, S. A., 2006. Effect of different growth promoters on the cecal microflora and performance of broiler chickens. Bulg. J. Agric. Sci., 12: 461-474 The objective of this study was an evaluation of the effects of different growth promoters: probiotic Lacto-Sacc® (Alltech, Inc. USA), nutritive premix Pharmastim and nutritive antibiotic Avilamycin on the cecal microflora and performance of bro...

The present communication deals with the study of seasonal prevalence of parasitic helminths in broiler chickens from Marathwada region of Maharashtra. The study was conducted during, annual cycle June 2012 to May 2013 from different sampling station and different season to estimate the seasonal prevalence of parasitic helminths. For this study annually 279 broiler chickens were randomly select...

Bacterial chondronecrosis with osteomyelitis (BCO) is a common cause of lameness in commercial broiler chickens worldwide. BCO represents substantial production loss and welfare issues of chickens. The bacterial species or communities underlying BCO pathogenesis still remain to be fully characterized. To gain insights on blood microbiota in broilers and its potential association with BCO, blood...

Campylobacteriosis is the most reported foodborne gastroenteritic disease and poses a serious health burden in industrialized countries. Disease in humans is mainly caused by the zoonotic pathogen Campylobacter jejuni. Due to its wide-spread occurrence in the environment, the epidemiology of Campylobacter remains poorly understood. It is generally accepted, however, that chickens are a natural ...
