Three levels of lysine (90, 100 and 110% of Ross requirement) and of pyridoxine (3, 6 and 9 mg kg-1) were used in a 3 × 3 factorial experiment to investigate the growth and blood antioxidant ability of broilers under high ambient temperature. None of the dietary supplements affected the weight gain during the starter and grower periods. Although no significant differences were detect...

the aim of present research was to locate genomic loci (qtl) on chromosome 2. itis associated with the carcass traits in japanese quail. the f1 population was created by using reciprocal crosses between two strains of white birds (layer) and wild (broiler) birds. the f2 birds (422 birds) were derived by random mating of the f1 birds. all of the f2 birds were slaughtered at 35 days of age and re...

Cause Chlamydiosis refers to an infection with organisms of the genus Chlamydia sp., which are bacteria that live within animal cells. Chlamydia psittaci is the species generally associated with this disease in birds. The severity of the disease differs by the strain of C. psittaci and the susceptibility of different species of birds. As a result, chlamydiosis may range from an inapparent infec...

This study was conducted to determine the effect of dietary turmeric rhizome powder (TRP) as a natural antioxidant, and soybean oil, canola oil and tallow on lipid metabolism, blood metabolites, immune system, and antioxidant status of broiler chickens before (BHS, 28 d) and after exposure to heat stress (AHS, 42 d). Seven hundred and ninety two d-old male Arian broilers were randomly allotted ...

background: corvidae is a cosmopolitan family of oscine birds including crows, rooks, mag­pies, jays, chough, and ravens. these birds are migratory species, especially in the shortage of foods, so they can act like vectors for a wide range of microorganisms. they live generally in temper­ate climates and in a very close contact with human residential areas as well as poultry farms. there is no ...
