In birds, it is thought that head movements play a major role in the reflexive stabilization of gaze and vision. In this study, we investigated the contributions of the eye and head to gaze stabilization during rotations under both head-fixed (VOR) and head-free conditions in two avian species, pigeons and quails. These two species differ both in ocular anatomy (the pigeon has two distinct fove...

1. Head injuries caused by aggressive pecking are an important welfare problem in quail farming. The aim of experiments one to three was to reduce the rate of aggressive pecking in breeder groups. 2. The quails were housed in pens containing litter, nest boxes and a dustbathing box. The experimental groups consisted of 2/14, 3/14, 5/15 or 5/35 (males/hens) quails which were introduced into the ...

Background: Campylobacter jejuni and Campylobacter coli are zoonotic bacteria which are frequently associated with human diarrhea. Sharing of the cytolethal distending toxin (cdt) genes in Campylobacter is common and is considered species specific. OBJECTIVES: In this study we focused on detecting the presence of cdt gene in C. jejuni and C. coli isolated from broilers, turkeys and quails of Ir...

Background & Aim:Hypericum perforatum L. is native to Iran. This herb is one of the most important medicinal plants and had many medical effects.This experiment was conducted to investigate the effects of feeding Hypericum perforatum and protexin on performance, carcass characteristics and intestinal morphology Japanese quails. Experimental: ...

The aim of the current work was to present main quality characteristics and composition meat most valuable parts carcass - breasts legs 35-day-old domestic quails from meat, dual-purpose egg-laying type. obtained results give basis assume that glycogen reserve pectoral muscle can be associated with productive type, which highest in type line WG (ΔрН=-0.573±0.053 compared ΔрН=-0.299±0.059 А, P<0...

Abstract Two experiments were conducted in order to evaluate the effect of dietary inclusion guava extract on laying performance and lipid stability egg Japanese quails. For first experiment, 384 quails with 42 days old distributed a completely randomized design four treatments (0.0; 3.0; 6.0; 9.0 g.kg-1 extract), 6 replicates, 16 birds/replicate. The experimental period lasted 84 days, divided...

The current research was carried out to investigate the effect of diets enriched with different levels organic iron on performance, egg quality, blood haematological parameters, and serum biochemical constituents in laying quails. In study, 120 female quails at 20 weeks age were allocated 5 treatment groups 6 replicates 4 each. Experimental formed by adding 0, 50, 100, 150, 200 mg/kg (iron-glyc...

insulin-like growth factor-1 gene (igf1) is a biological candidate gene for investigation traits such as growth, body weight and muscles growth in different species. in this research eight pairs of white and wild quails were crossed reciprocally as a base population. a total of 34 quails were produced in first generation (f1) and 422 quails were generated by intercrossing the f1 population. bod...
