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...

Four diets with different crude protein levels 17.75%, 19.95%, 21.85%, 24.08% were used to feed 192 seven-week-old yellow quails in this experiment. During 50-day-old to 95-day-old, laying rate, feed intake and egg weight were recorded to analysis the effect of different levels of dietary protein on the performance of yellow quails. All fences were collected and analysis the effect of different...

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...

Ornithobacterium rhinotracheale (ORT) is a respiratory pathogen which has been isolated throughout the world from numerous bird species. The present study was designed to isolate and characterize the ORT from domestic turkeys, quails and pigeons. For this purpose, 250 samples from each bird species (turkey, quail and pigeon) with or without respiratory signs were tested by taking of tracheal...

Two experiments were conducted to evaluate the effect of substituting different levels of hazelnut kernel oil meal (HKOM) for dehulled soyabean meal (DSBM) in diets for Japanese quail. Five diets in which HKOM was replaced with 0, 25, 50, 75 and 100% of DSBM protein in a growing diet for a 5 week period using 450 Japanese quails of initial age of 1 week and in a layer diet for a 112 days period...

The response of laying Japanese quails to dietary levels of energy and protein on performance, egg quality, hatchability, fertility and their effect on subsequent offspring live body weight was investigated. A total of 432 Japanese quails (13 weeks old) were divided into nine treatments. Each treatment comprised of four replicates of twelve birds (9 females and 3 males). Nine diets including th...
