This study aims to determine the effect of in-ovo injection L-arginine into local chicken eggs on embryo development and chick performance chicken. A total 160 were incubated using semi-automatic incubator with temperature 37-38C relative humidity 55-65%. The injected solution has a concentration 0.5% (m/v). In treatment was divided 4 groups, first without (control), second 0.2 mL (m/v)/egg, th...

Avian leukosis retroviruses (ALV) cause lymphomas and other cancers in chickens. Previous studies have used enzyme-linked immunosorbent assays (ELISA) and indirect immunofluorescence assays (IFA) to detect ALV p27 group-specific antigens (GSA) in commercial chicken eggs. In the poultry industry eradication programme against exogenous ALV, ELISA assays are used to identify chickens infected with...

Salmonella enterica consists of over 2,000 serovars that are major causes of morbidity and mortality associated with contaminated food. Despite similarities among serovars of Salmonella enterica, many demonstrate unique host specificities, epidemiological characteristics, and clinical manifestations. One of the unique epidemiological characteristics of the serovar Enteritidis is that it is the ...

All nutrients including proteins, lipids, vitamins, minerals and growth factors required by the developing embryo, as well as a number of defense factors, can be found in avian eggs. Eggs are also a source of other substances with biological functions and activities inter alia immune proteins and enzymes. Although chicken egg consumption is currently at the highest level, eggs from other specie...

Heat stress and exhaustion is one of the top causes of chicken death. For those new to backyard chicken farming, it is important you learn to recognize the signs of this serious condition and how to keep your chickens cool and hydrated. Chicks, especially, need extra attention to help them remain healthy. For a flock of laying hens, knowing how to prevent heat exhaustion and treat a chicken suf...

A case-control study was conducted from 1 January to 31 May 2003 to identify risk factors for S . Heidelberg infection in Canada. Controls were pair-matched by age group and telephone exchange to 95 cases. Exposures in the 7 days before illness/interview were assessed using multivariate conditional logistic regression. Consumption of home-prepared chicken nuggets and/or strips [matched odds rat...

The first staff member to become ill did not consume the potato pie or rice pudding. Nonetheless, the staff member reported handling and cracking the raw eggs included in the rice pudding. The staff member reported that the exterior surfaces of the shell eggs were visibly contaminated, however, there were no reported breaks in the integrity of the eggshells. A trace-back investigation identifie...

The role of microbes associated with chicken litter in the suppression of Meloidogyne arenaria in amended soil was investigated. Amended soil treatments were prepared, including combinations of sterile and nonsterile chicken litter and soil. Microbial biomass in different treatments was compared by measuring carbon dioxide evolution. There was less CO evolved in sterile litter than in nonsteril...

Noninfectious hemagglutinins were prepared from the allantoic fluids of embryonated chicken eggs infected with Sindbis virus or with Murray Valley encephalitis virus.
