“…Studies by Abdel-Tawab [15] and Baylan et al [16,17] highlighted the impact of body weight selection procedures on various parameters, including body weight, weight gain, feed intake, and feed efficiency. The selected lines in these studies consistently demonstrated higher body weights at hatch and throughout subsequent generations.…”

HIS research aims to investigate the antioxidative potential of dietary chitosan (CH) and nanochitosan (NCH) supplementation on the gene expression of pivotal antioxidant defense system components, namely SOD (superoxide dismutase) and CAT (catalase) genes. These genes are instrumental in safeguarding cells against the deleterious effects of reactive oxygen species. The study extends its scope to evaluating the hepatic and intestinal histology in two distinct lines of Japanese quail. Carried out as a fully randomized design experiment with 10 treatment groups, the research encompassed 840 one-day-old Japanese quails from two distinct lines: Sq, selected for body weight at 30 days after 42 generations of selection, and Jq, a control line without selection. Each line was further divided into five treatment groups, with three replicates per group and 28 unsexed chicks per replicate. The treatment groups included a baseline diet according to NRC (1994) guidelines, two groups supplemented with chitosan (CH) at 50 and 70 mg/kg diet, and two groups supplemented with nano-chitosan (NCH) at 30 and 50 mg/kg diet for both Sq and Jq lines. The study outcomes shed light on the varying concentrations of chitosan (30, 50, and 70 mg/kg) and their impacts on live body weight, CAT and SOD gene expression levels, as well as histopathological changes in the liver and intestine. The findings revealed discernible effects across all tested concentrations, elucidating the multifaceted influence of chitosan and nanochitosan supplementation on the examined parameters.

“…The findings suggest that chitosan, as a feed supplement, stimulates the release of digestive enzymes and lessens diarrhea in animals while improving intestinal morphology, villus structure, microbiota, and nutritional digestion and absorption (12,15,17)).…”

In this study the heritability of body weights of Japanese quails (Coturnix coturnix Japanica) was estimated by using ML (Maximum Likelihood) methods. Firstly, the variance components were estimated by using ML method which were later estimated the heritability for weekly body weights. The estimation of heritability of body weights are following: for third week: 0.272±0.066, for fourth week: 0.60±0.13, for fifth week: 0.312±0.074

This study was carried out to investigate selected traits of hatched and unhatched eggs and chick growth performance of yellow Japanese quails (Coturnix japonica). Eggshell temperature at the time of transfer to the hatcher was higher in hatched eggs (38.09 o C) than in unhatched eggs (37.43 o C) (p=0.000), lower in eggs with in early embryonic mortality (37.39 o C) than those with late embryonic mortality (38.13 o C) (p=0.000), and higher in eggs with female chicks (38.14 o C) than those with male chicks (37.95 o C). Lower eggshell, yolk, and albumen weights were determined in eggs with embryonic mortality of 17-18 days (0.58 g, 3.13 g and 4.96 g) compared with those with 10-16 days (0.67 g, 3.55 g and 5.58 g) and embryonic mortality of 1-9 days (0.75 g, 3.95 g and 6.19 g) (p=0.000). Lower egg weight loss was obtained in eggs with embryonic mortality (13.85%) of 1-9 days than those with embryonic mortality of 17-18 days (26.48%) (p=0.001). Females were heavier at chick weight (8.98 g vs. 8.63 g; p=0.033) and at 4 (231.81 g vs. 211.43 g; p<0.000) and 5(260.69 g vs. 231.87 g; p<0.000) weeks of age than males, and had longer left shanks (34.39 mm vs. 33.61 mm; p=0.004).
