the present research was conducted to estimate the dietary lysine (lys) requirements of growing quails as based on performance and carcass constituents parameters at 3 to 24 d of age. the experiment was carried out in a complete randomized design arrangement the 6 dietary lys levels; 1, 1.15, 1.30 (nrc 1994), 1.45, 1.60, and 1.75 %, from 3 to 24 d of age. a dose-response diet mainly based on co...

The current study was conducted to investigate the effects of genetic and non-genetic factors on body weight and carcass traits of Japanese quails. Two strains of Japanese quail (150 wild quails and 150 white quails) were used as base population. Four mating groups were used to produce progenies: wild male × wild female, white male × wild female, wild male × white female and white male × white ...

The effects of feeding diets containing Salbutamol (0, 1, 3, 5 and 7 mg/kg diet) from 21 to 49 days of ageon growth performance and carcass characteristics in 180 male and 180 female Japanese quails (Coturnixjaponica) were studied using a factorial arrangement based on completely randomized design. Gender hadsignificant effect on weight gain (Pwere not statistically significant (P>0.05). Salbut...

To determine the effect of using Aloe vera and protexin probiotic on performance, carcass characteristics and some blood biochemical in Japanese quails, a total 300 ten days old Japanese quails quail chicks with an average weight of 19.5±5 g were divided into 8 treatments with 3 replicates as factorial randomized design experiment. The quails were fed by basal diet as control diet, (0 and 1 g.k...

this study has been carried out to investigate the effect of short-term divergent selection for 4-wk body weight on growth curve parameters and carcass components in japanese quail. quail lines utilized were two divergently selected for high (hw) and low (lw) 4-wk body weight (bw) as well as a line as control (c). the results of the study indicated that quails in hw line had heavier bw than tho...

The effect of dietary Terbutaline, a beta adrenergic agonist, on carcass characteristics and blood attributes in 288 Japanese quails was studied from 21 through 49 days of age. Dietary treatments included four levels of Terbutaline [0 (T0), 1 (T1), 3 (T3), and 5 (T5) mg/Kg of the diet]. Quails were bled at the end of the trial for biochemical assays and the carcass characteristics were then mea...

The present study aimed to investigate the effects of different levels of dietary metabolizable energy (ME) and crude protein (CP) on performance and carcass characteristics of Japanese (Coturnix japonica) and Brown (Coturnix ypsilophorus) quails during a 42 d feeding trial. A total of 720 (360 per each species) one week-old quail chicks were randomly (by species) distributed between 72 cages a...
