The subgroup J of ALV (ALV-J) has emerged as an important pathogen of meat-type chickens since1989. This virus is responsible for economic losses due to both mortality and depressed performance inchickens. So, the objective of this study is the detection of ALV-J in the albumen of commercial and nativefowl eggs using RT-PCR. Three hundred and seventy egg albumens were randomly selected from dif...

Feed deprivation is commonly used by the poultry industry to induce molting and stimulate multiple egg-laying cycles. However, feed deprivation has been observed experimentally to increase susceptibility of poultry to Salmonella infections. Previous studies indicated that alfalfa was efficacious in reducing Salmonella; the present investigation was designed to evaluate the efficacy of combined ...

A cross sectional study was carried out to assess the epidemiological measures of disease occurrence and casual association of Marek’s disease (MD) in 12 different commercial layer flocks. Twenty representative blood and feather tip samples were collected from 12 different MD outbreak flocks. All the samples from each flock were pooled together and subjected to PCR using serotype 1 specific pri...

Growth performance of commercial brown layer chicks (Shaver 579; n = 408) was studied in an open-sided house by feeding layer starter and layer grower diets during 0-17 weeks of age. The experimental period was divided into three phases: Phase I (0-4 weeks), Phase II (5-7 weeks) and Phase III (8-17 weeks). Both growth and feed consumption closely followed the standard data except during 10, 11,...
