objective: in recent years, amino acids are used in veterinary medicine for many purposes. they injected into hatching eggs to increase chick body weight and performance at hatch, but the adverse effects of amino acids have always been a major concern. there is scant information available about the pathological alterations of amino acids in the chicken embryonated eggs. the objective of this st...

Turtle eggs, 24 h old, were infected with Arizona hinshawii and treated 48 h later with gentamicin sulfate (Garasol; Shering Corp., Allantown, N.J.) by pressure differential egg dip treatment to ascertain the concentration of this reagent required to eradicate this pathogen from eggs. Infected eggs treated with 1,000 or 1,500 micrograms of gentamicin per ml of dip solution eliminated detectable...

objective: in recent years, antiviral drugs have been used widely in the glob to prevent and treat viral diseases. they injected into eggs to eliminate pathogens and prevent of egg transmission of disease, but the adverse effects of drugs have always been a major concern. there is little information available about the safety of antiviral drugs in the embryonated eggs of birds. the objective of...

Pathogens are an important and significant hazard for human and animal health. In recent years, antibiotics are used to treat different types of infection caused by bacterial agents. In veterinary medicine, antibiotics injected into hatching eggs to eliminate pathogens and prevention of egg transmission of disease, but the adverse effects of drugs have always been a major conc...

The present study aimed at evaluating the effect of the dietary inclusion of organic trace minerals selenium and zinc on the performance and internal and external egg quality of Japanese quails submitted to heat stress. Data on egg production, feed conversion (kg feed intake/ kg eggs and dozen eggs), egg weight, egg specific gravity, eggshell thickness and weight, Haugh unit, yolk index, albume...

The transmission, control and the relationship between Dicrocoelium dendriticum and its definitive (sheep and cattle) and intermediate (molluscs and ants) hosts under natural and experimental conditions are described. Eleven species of molluscs and four of ants were found infected with larval D. dendriticum in León province, north-west Spain. Infected ants were observed between April and Novemb...

Objective: In recent years, antibiotics have been used widely in the glob to prevent and treat bacterial diseases. They injected into eggs to eliminate pathogens and prevention of egg transmission of disease, but the adverse effects of drugs have always been a major concern. There is little information available about the safety of tetracycline drugs in the embryonated eggs of the birds. The ob...

The effect of the rhg1 gene on equilibrium population densities (E) and reproduction factors (Rf) of Heterodera glycines was studied by comparing the nematode population development on two near-isogenic soybean lines (NIL), differing at the rhg1 locus. The NIL were inoculated with a series of initial egg densities (Pi) in the greenhouse. The relationships between final population densities (Pf ...

BACKGROUND AND PURPOSE Although a criterion reference of 10,000 steps per day is recommended for health benefits, a literature search yielded no normative standard for daily steps. Therefore, a meta-analysis was used to estimate the number of pedometer-documented steps that adults take daily. METHODS Studies were retrieved using electronic databases and cross-referencing from retrieved studie...

Fish spawning is often used as an integrated measure of reproductive toxicity, and an indicator of aquatic ecosystem health in the context of forecasting potential population-level effects considered important for ecological risk assessment. Consequently, there is a need for flexible, widely-applicable, biologically-based models that can predict changes in fecundity in response to chemical expo...
