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...

susceptibility of eggs, nymphs and adults of greenhouse whitefly (trialeurodes vaporariorum westwood) and adults of green peach aphid (myzus persicae sulzer) to pirimicarb (pirimor®) and citowett oil alone vs. in combination was evaluated under greenhouse conditions. the glass vial and leaf dipping methods were employed for bioassay of adults vs. the immature stages (egg, nymph and pupa) of gre...

Penetration of the hatching egg shell by microorganisms results in embryonic mortality, weak chicks, high chick mortality, and poor chick growth. The most effective sanitation system involves treating the eggs as soon as they are collected from the nest and before microorganisms penetrate the shell. Several recent research studies have examined the effectiveness, safety and ease of use of commo...

An outbreak of H7N2 low-pathogenicity (LP) avian influenza (AI) occurred in a two-county area in Pennsylvania from December of 1996 through April of 1998. The outbreak resulted in infection of 2,623,116 commercial birds on 25 premises encompassing 47 flocks. Twenty-one (one premise with infection twice) of the twenty-five infected premises housed egg-laying chickens and one premise each had tur...

Horizontal and temporal variations in abundance and productivity of phytoand zooplankton were studied in a frontal area in the NW North Sea during September and October 1985. In addition, distributions of several cohorts of herring larvae found in this area were monitored and larval growth and survival estimated. Phytoplankton biomass and productivity as well as copepod productivity peaked in t...

AIM This research was conducted to determine the most affecting parameters on hatchability of indigenous and improved local chickens' eggs. MATERIALS AND METHODS Five parameters were studied (fertility, early and late embryonic mortalities, shape index, egg weight, and egg weight loss) on four strains, namely Fayoumi, Alexandria, Matrouh, and Montazah. Multiple linear regression was performed...

Any food-based interventions must take into account these five concepts in order to make it successful; Acceptable, Feasible, Affordable, Sustainable and Safe (AFASS) [2]. It is very important to choose appropriate and cost-effective intervention strategies for the target population and this require pre knowledge about the nutritional status of this population, another important determinant one...

Female spawning-site preference within a nest and its effect on the female mate choice in a paternal brooding blenny Rhabdoblennius ellipes, were examined in rocky intertidal pools using artificial nests. The number of eggs deposited at the nest entrance site was lower than the number deposited at the center and at deep sites. Moreover, the within-nest difference in the egg developmental stage ...

Nitric oxide (NO) fumigation under ultralow oxygen (ULO) conditions was studied for its efficacy in controlling codling moth and effects on postharvest quality of apples. NO fumigation was effective against eggs and larvae of different sizes on artificial diet in 48 h treatments. Small larvae were more susceptible to nitric oxide than other stages at 0.5% NO concentration. There were no signifi...

An experiment was conducted in Jessore district of Bangladesh during the period from January 2003 to December 2004 to investigate the performance of Brown Shelled Hybrid Layer, White Shelled Hybrid Layer and Native Hen measured during only laying period (57 weeks). 8 Brown Shelled Hybrid Layer farms, 8 White Shelled Hybrid Layer farms and 10 Native Hen farms were reared intensive, intensive and...
