Nowadays antibiotics are used on a large scale in veterinary and human medicine to cure or prevent diseases. Some antibiotics injected into hatching eggs to eliminate pathogens and prevention of egg transmission of disease. Adverse effects of drugs have always been a major concern. There is scantly information available about the safety and pathological alterations of lincosamide-aminocyclitol ...

The present work was carried out to isolate and identify fungi species present in dead-in-shell chick embryo. A total of three thousand dead-in-shell embryonated chicken eggs pooled into 300 eggs (10 eggs per group) were collected from the four hatcheries over a period of six months. The contents of the pooled eggs were inoculated onto Sabourauds Dextrose Agar (SDA) and Corn Meal Agar (CMA) sla...

To prepare for influenza pandemics that may be caused by the H2 and H6 subtype influenza viruses, live attenuated influenza virus (LAIV) H2 and H6 vaccines are being developed and evaluated. The H2 and H6 vaccine candidates with different receptor binding preferences specified by amino acid substitutions at residues 226 and 228 were generated and evaluated for their growth in embryonated chicke...

Plant surfaces covered with crystalline epicuticular waxes are known to be anti-adhesive, hardly wettable and preventing insect attachment. But there are insects that are capable of gluing their eggs to these surfaces by means of proteinaceous secretions. In this study, we analysed the bonding region between the eggs of Crioceris asparagi and the plant surface of Asparagus officinalis using lig...

OBJECTIVE To assess the effects of prenatal administration of valproic acid on the survivability and day of hatching of chick embryo in comparison with age-matched controls. METHODS The experimental study was conducted at the Department of Anatomy, Regional Centre of College of Physicians and Surgeons Pakistan, Islamabad, from February 2010 to February 2011. Fertilised chicken eggs were divid...

Objective: In this study, the effect of diet food (soybeans, egg yolk and chicken manure) on biomass weight and body composition (the amount of protein, fat, moisture and ash) Chironomid larvae were examined. Methods: For this purpose, 2.5 grams of food per Coconut considered in the period, with three replicates and Chironomid larvae during the period of 15 days in plastic pans were kept in nut...

Chicken eggs are animal foods that consumed by many people because they cheaper and easier to obtain than other foods. Bay leaf is known the public as one of most popular kitchen spices not only its health benefits, but also attractive organoleptic quality (aroma). Eggs soaked in bay infusion expected produce qualities without affecting their chemical (fat content).
 The research design us...

Aim: An experiment was conducted to determine the effect of egg weight on hatchability, embryonic deaths and hatchling weight of three rural breeds (Fayoumi, Desi and crossbred (Rhode Island Red X Fayoumi) chickens. Materials and Methods: Three different egg weight groups classified into small: (<41g), medium (41-45g) and large (> 45g) were used in the experiment. A complete randomized design w...

BACKGROUND Tylosin and Josamycin are macrolide antibiotics. They are used in the treatment of pneumonia, arthritis and mastitis in cattle, and mycoplasma infections in poultry. The incorrect use of antibiotics has lead to the presence of antibiotic residues in foods. The residues cause toxic effects on consumers. RESULTS A simple and sensitive method was optimized and validated for the analys...
