This experiment aimed to study the effect of dietary thyme and turmeric essential oils supplementation on growth performance, nutrient utilization economics Japanese quails. For this purpose, a total 180 six-day-old quail chicks were randomly assigned into five different treatment groups, each with three replicates (12 birds per replicate). The was conducted for 35 days. Different groups quails...

I . Adult male Japanese quail (Coturnix Coturnix Japonica) were overfed at different intensities during varying periods: (I) by gradually increasing the daily amount of food up to twice the control level in a period of 1 1 d and keeping this level constant during the subsequent 12 d period (prolonged overfeeding); ( 2 ) by gradually increasing the daily amount of food up to approximately twice ...

Decades of selective breeding have yielded lines of poultry with substantial myofiber hyperplasia, vet little is known about what genes have been altered during the course of selection. Myostatin is a strong negative regulator of muscle mass in mice and cattle and could have been one of many genetic factors contributing to increased myofiber deposition in growth-selected lines of poultry. To te...

The present study was executed to compare breeder performance parameters (feed intake, Age at 1st egg, egg weight, hen day & hen house production %, FCR /kg and/dozen eggs) in mass selected (MS), pedigree based selected (PS) and random bred controls (RBC), in three consecutive generations of Japanese quail. In generation1 (G1), 11000 quail chicks were randomly distributed into 22 sub-groups. Af...

The aim of this study was to determine effects of dietary supplementation with chitosanoligosaccharides (COS) and L-carnitine, individually or dually, on growth performance, carcass traits and some blood serum parameters in quails. A total of 192, four days old, Japanese quail chicks were allotted four groups, each of which included four replicates (12 birds per replicate). The groups received ...

AIM The growth promoting effect of the blue-green filamentous alga Spirulina platensis (SP) was observed on meat type Japanese quail with antibiotic growth promoter alternative and immune enhancing power. MATERIALS AND METHODS This study was conducted on 180 Japanese quail chicks for 4 weeks to find out the effect of diet type (vegetarian protein diet [VPD] and fish meal protein diet [FMPD])-...

This study investigated the Pennyroyal in terms of its effects on performance and meat quality (color pH) Japanese quails different levels. A total one day-old quail chicks were randomly distributed to a control two experimental groups containing three levels pennyroyal (0.0, 0.1 0.2 %). Each group was divided into five repetitive with, ten each group. At end experiment, values parameters measu...

The aim of this study is to determine the effects adding different levels red pepper oil quail diets on performance, slaughtering characteristics, and some serum parameters. For purpose, a total 300-day-old mixed-sex chicks were randomly assigned 5 treatment groups with 6 replications 12 each. Experimental animals fed for 35 days prepared by 0, 300, 600, 900 or 1200 mg/kg oil. During experiment...

The present study was conducted to investigate the effects of dietary lysine (Lys) and sex on growing quail performance and immunity parameters. The six dietary Lys: 10, 11.5, 13.0 (NRC 1994 recommendation), 14.5, 16.0 and 17.5 gr/kg were provided. The other essential amino acids except lysine were provided to meet or exceed NRC 1994 recommendation for growing quail. This experiment was carried...

The present study was executed to examine the growth performance and economic efficiency of Japanese quail (Coturnix coturnix japonica) at Avian Research and Training (ART) Centre, UVAS, Lahore. For this purpose a total of 3200 quail chicks were allocated to four different feed restriction regimes comprising four close-bred stocks (Imported, Local-1, Local -2 and Local-3) at the age of 10 days....
