Twenty-four poultry farms in four major provinces of the Lebanon were investigated to verify the first emergence of avian influenza (AI). Both the meat chicken breeders and commercial chicken layers presented a significant average drop in egg production equivalent to 46% and 47.3%, respectively. However, the average drop in egg production in the free-range(More)
This study was designed to examine the impact of competitive non-protective antigens in a bivalent killed vaccine of Newcastle disease virus and infectious bronchitis (IB) virus on seroconversions against protective fusion protein of Newcastle disease (ND) virus (NDV), in free-range layers primed by live ND-clone 30 and IB-H120 vaccines. The experimental(More)
The total polyaromatic hydrocarbons (TPAH) and the total polychlorinated biphenyls (TPCB) that originate from oil spills in sea and ocean waters are toxic to fish and their offspring. The authors compare the levels of organic contaminants (TPAH and TPCB) recovered from the bile versus the dorsal muscles of 120 individual Mugil spp. that were harvested from(More)
Livestock keeping constitutes a traditional and important economic activity in the Arab region. This paper aims to assess the role of the Arab livestock sector in food and nutritional security in terms of demand, supply, national policies and trade in the light of major environmental constraints, with data illustrations from Morocco (Mediterranean country)(More)
AIMS This work aims at studying the impact of competitive exclusion of Salmonella serotype Enteritidis infection in layer chickens, by microbiota of fresh and dried-modified yoghurt, on egg production and weight, protection against infection, and on yolk-antibody and cholesterol levels. METHODS AND RESULTS Four groups of 27-week-old layer chickens were(More)
The authors evaluate the impact of a synergistic preparation (SP) of supplements (a combination of calcium phosphomycin and tylosine tartarate) on the performance of broilers with a history of carcass condemnation at slaughter. The experiment included 120-day old broilers (Ross 308), divided equally into two treatment groups, with three replicates per(More)
The present study has two aims: to optimize the antiviral activity of oseltamivir in chicken embryos against an avian influenza-H9N2 strain (P0) and to apply the optimized protocol for studying the drug susceptibility of 4 H9N2 mutants (M1, M2, M3, and M4). As for the first aim, oseltamivir antiviral activity was monitored upon its delivery into 9-day-old(More)
Primary infection by low pathogenic avian influenza (LPAI) predisposes for secondary infection by Escherichia coli in poultry, leading to significant economic losses. Future research in control of this ailment requires the establishment of a successful controlled challenge by avian influenza virus (AIV)/E. coli. Six groups of broilers (6 birds/group) were(More)
