The article presents the results of laboratory tests for presence heavy metals and pesticides when adding a mineral feed additive to diet birds. relevance study is related cultivation healthy highly productive quails in order ensure food security Republic Kazakhstan. conducted studies meat assess indicators purpose using on experimental birds (quails) allowed us obtain following results: all sa...

The purpose of the current study was to detect effects different levels rosemary volatile oil (VO) supplemented laying quail diets on performance, egg quality parameters, and yolk oxidative stability. In this study, a total 105 quails (Coturnix coturnix Pharaoh) at age 6 weeks were used 3 main groups formed, each containing 35 quails. Also, group separated into 5 replicates an equal number Quai...

in this study parasitic infection of bobwhite and japanese quails were clarified in farms of garmsar city in province of semnan. forty quails from two breeds randomly were selected and they examined to identify all internal and external parasites .finding was shown that five percent of the quails examined harbored one or more species of helminthes. two cestodes, raillietina echinobothrida and r...

Estimation of growth curves of poultry species is of particular importance in animal science. This study aims at fitting hierarchical Gompertz growth curve to Japanese quails body weight data obtained from hatching to 56 days of age weekly. The model involved a random animal effect as well as sex and line effects in asymptotic weight parameters. Model parameters were estimated via Bayesian meth...

Low pathogenic Avian Influenza Viruses (LPAIVs) are a persistent threat to poultry and have zoonotic potential. Wild birds such as Ducks and Quails may serve as not only carrier but could be intermediate host for mutation of viruses into highly pathogenic forms. Present study compares pathogenesis of LPAIV H7N3 in chicken, ducks and quails. Thirty-two birds of each species were grouped accordin...

The study was conducted to determine the effect of varying protein levels and preservation method on internal egg qualities of Japanese quails. A total of 180 birds were randomly allotted into three dietary treatments in a completely randomized design (CRD) replicated six times. A factorial arrangement of 3x4x4 which involves 3 protein levels, 4 storage method and 4 time intervals was designed ...

To evaluate the action mode of Berberis vulgaris root extract in the alleviation of oxidative stress, female Japanese quails (n 180, aged 5 weeks) were reared, either at 22°C for 24 h/d (thermoneutral, TN) or 34°C for 8 h/d (heat stress, HS), and fed one of three diets: diets containing 0, 100 or 200 mg of B. vulgaris root extract per kg for 12 weeks. Exposure to HS depressed feed intake by 8·5...

This study was conducted to determine the effect of inclusion sodium bentonite (SB) in Japanese quails’ diet on performance, carcass traits, blood biochemical status, and meat quality traits. A total 120 seven-day-old quails ( Coturnix coturnix Japonica ) were randomly divided into four groups, with each group containing five replicates, six birds each. SB mixed at concentrations (0, 0.5, 1.0 2...

In the system of full-fledged poultry feeding, particular importance is attached to providing them with mineral substances. The purpose this study was determine effect Apimin additive based on bee podmore content zinc, copper, magnesium, and iron in meat, liver, bone tissue quails. During study, following methods were used: zootechnical (to analyse productivity quails), physiological digestibil...

The present study was carried out to determine the effects of the inclusion of a spore-forming probiotic (Bacillus subtilis) in laying Japanese quail diets as an alternative to growth-promoting antibiotics to help produce healthy eggs and meat. This experiment was conducted as a completely randomized design with three treatments (control, 0.05% bacitracin methylene disalicylate (BMD), or 0.1% B...
