Pheasants and chickens were compared as sentinels for monitoring the transmission of arboviruses of public health significance in Florida during 1991-93. Results suggest that pheasants are better sentinels for eastern equine encephalitis (EEE) virus. They detected virus transmission 3-6 weeks earlier in epizootic years, 2-4 times more frequently during the season, and twice as many birds within...

Chickens were bursectomized by cyclophosphamide treatment at hatching. At 8 or 9 weeks of age, bursectomized and unbursectomized hatchmates, free from prior infection, were challenged with pathogenic Marek's disease virus. Oncogenicity of the virus inoculum was confirmed by inoculating 1-day-old susceptible chickens. At the time of virus challenge, blood cells from the cyclophosphamide-treated ...

Transmission of the virus of St. Louis encephalitis to normal chickens by the bite of infected mites (Dermanyssus gallinae) has been demonstrated. Both experimentally infected and naturally infected mites were shown to be capable of transferring the virus of St. Louis encephalitis to chickens by bite. Virus is present in the blood of such chickens in small amounts, so that demonstration of vire...

Ascaridia galli worm was chicken parasite that inflicted significant economic loss for breeders. Expensive commercial anthelmintic drug and resistance were the reasons why herbal study became strategic. The aimed at finding out effect of application turmeric (Curcuma domestica) extract in vivo on number eggs per gram (EPG) feces. It used 30 free ranging chickens classified into 2 groups 5 with ...

A survey of beak morphological abnormalities was performed on 6,201 chickens (egg-laying hens and chickens for meat production belonging to 25 flocks) brought to a poultry processing plant. The observed abnormalities varied among flocks with occurrence rates ranging from 0.48 to 46.67%. The occurrence was high in flocks subjected to beak trimming and varied significantly according to chicken br...

There is a critical need to have vaccines that can protect against emerging pandemic influenza viruses. Commonly used influenza vaccines are killed whole virus that protect against homologous and not heterologous virus. Using chickens we have explored the possibility of using live low pathogenic avian influenza (LPAI) A/goose/AB/223/2005 H1N1 or A/WBS/MB/325/2006 H1N2 to induce immunity against...

The present study was conducted to investigate whether dietary sanguinarine (Sangrovit ® , SGV) could affect growth performance, relative organ weigths, gut microbiota, serum cholesterol levels, and malondialdehyde contents of leg meat in broiler chickens. A total of 840 day-old male broiler chicks (Ross breed) was randomly placed on 28 floor pens with rice straw as a bedding and subjected to o...

The experiments aimed to develop the inactivated Newcastle disease (ND) vaccine in the form of water in oil (WO) and water in oil in water (WOW) using palm oil, which is easily found in tropical countries, and to study the effect of vitamin E in the form of dl-α-tocopheryl acetate for improving the efficacy of inactivated ND vaccine prepared from palm oil. Two hundred and twenty, thirty five da...

Newcastle disease virus (NDV) infects most avian species. The serious consequence is the disease (frequently fatal) that occurs when virulent strains of the virus infect domestic chickens. The epidemiology of Newcastle disease (ND) in commercial chickens is fairly well understood. Infected chickens are the usual source of virus, which can be transported mechanically by fomites or by people. Pre...
