“…These high estimates agree with data in the literature on Japanese Quail. The heritability of body weight was reported to be 0-82 (Garwood & Diehl, 1987) and 0-84 for the metatarsus (Isogai, 1971). Data also agree with high responses to selection for body weight in Japanese Quail (Marks, 1988).…”

This study investigated genetic variation in growth and final size in relationship to differences in heritabilities under good and poor feeding conditions. Heritabilities of growth and final size were estimated for several traits under ad libitum and restricted feeding conditions. A 30 % feed restriction from hatching to 44 days of age in Japanese quail chicks decreased body weight and tarsus length at 44 days of age and the length of the third primary covert feather at 24 days of age relative to controls fed ad libitum. Wing length at 44 days of age was not significantly different for ad libitum fed and restricted quail. Genetic variances for body weight and tarsus length were very large throughout growth which resulted in heritability estimates close to one for these traits. The genetic correlations among feeding treatments were low, indicating that different genes were affecting growth under the two treatments. Growth was described by the components: asymptote, growth period, and shape of the growth curve following the modified Richards growth curve model (Brisbin et al. 1986). Tarsus length, which had high heritability of the parameter 'growth period' of the model, tended to display a higher heritability under the restriction than under ad libitum feeding. Body weight and feather length, which had either no heritable or low heritable ' growth periods' estimates, tended to be more heritable under ad libitum feeding. The shape parameter of the growth curve was not heritable for any trait, except tarsus length under restricted feeding.

“…They have less feed requirement and an adult quail requires only 20-25 g feed per day compared to chicken (120-130g) per day (Ani et al, 2009). Other unique characteristics and advantages of quails over other species of poultry include early attainment of sexual maturity, being able to come to lay as early as 5-6 weeks of age, having short generation interval making it possible to have many generations in a year (Robbins, 1981;Annon, 1991), attaining market weight of 150-180 g between 5-6 weeks of age and a high rate of egg production between 180-250 (Garwood and Diehl, 1987) and 200-300 eggs in their first year of lay (NRC, 1991). Reports by Haruna et al (1997) and Olubamiwa et al (1999) showed that quail meat and eggs are renowned for their high quality protein, high biological value and low caloric content, making it a choice product for hypertension prone individuals.…”

The present study established the reference values and sex differences in the erythrocytic and serum biochemistry parameters of domestic adult quails (Coturnix coturnix). Ninety five adult birds, comprising of 42 males and 53 female Japanese quails were sampled using a simple random sampling technique. Standard procedures were carried out in all haematology and serum biochemistry determinations. The overall mean for the erythrocytic and serum biochemistry parameters were as follows: packed cell volume (PCV) 43.11%, red blood cell count (RBC) 4.31 × 10 6 /µl, haemoglobin concentration (Hbc) 16.21 g/dl, mean corpuscular volume (MCV) 100.69 fl, mean corpuscular haemoglobin (MCH) 39.17 pg, mean corpuscular haemoglobin concentration (MCHC) 39.35 g/dl, aspartate aminotransferase (AST) 59.99 IU/L, alanine aminotransferase (ALT) 20.85 IU/L, alkaline phosphatase (ALP) 107.54 IU/L, total proteins (TP) 5.19 g/dl, albumin (ALB) 3.25 g/dl, globulin (GLB) 1.94 g/dl, albumin: globulin 1.73, total cholesterol (TCHOL) 146.69 mg/dl, total bilirubin (TBIL) 2.37 mg/dl, uric acid (UA) 16.02 mg/dl and creatinine (CREAT) 0.44 mg/dl. The PCV of the males were significantly higher than that of the females, while the MCH and MCHC of the females were significantly higher than those of the males. The serum total proteins, albumin, globulin, uric acid, creatinine, and total cholesterol values of the female quails were higher than those of the male quails. The present data might be useful to avian specialists and veterinary clinicians, but more research works should be carried out on quails to increase the information data base, especially in the tropics.

“…The meat and egg are delicious, noted for high dietary and even medicinal values (2). The meat is lean and both the egg and meat are low in cholesterol (3). Quails could be a good and economical source of animal protein because of their fast growth potential, early maturity, high rate of egg production, short generation interval and small body size that allows large number of birds to be kept in a small space.…”

Characteristics and proximate compositions of Japanese quail carcass in a semi arid area of Nigeria were determined at the Poultry Unit of the Department of Animal Science, University of Maiduguri using 300 random bred Japanese quail. Sex, color type, weight group and age had significant effects on carcass characteristics. Sexual dimorphism was in favor of the females for most carcass characteristics; however, dressed percent (72.41%) was significantly higher in males than females (68.02%). Wild type Japanese quails had significantly higher slaughter weight (132.66 g) than light brown (121.33 g). The values for most carcass traits increased with increase in age and weight of birds. Abdominal fat deposit in the Japanese quail became noticeable only at 24 weeks (1.39 g) of age and increased to 10.70 g at 52 weeks. The mean values of moisture, dry matter, protein, ether extract and ash in whole Japanese quail carcass were 78.22, 21.78, 15.55, 12.23 and 2.91%, respectively. The corresponding values for breast meat were 78.88, 21.12, 17.90, 2.01 and 2.28% while those of thigh were 82.28, 17.72, 13.63, 2.91 and 2.86%. Age had effect on composition of whole carcass, breast and thigh meats, moisture content of whole quail carcass decreased with a reversing trend for dry matter, crude protein and ether extract. At 6 weeks of age, moisture in whole quail was 14.85% higher than at 24 weeks. In contrast, at 24 weeks dry matter, crude protein and ether extract were 11.06, 7.89 and 17.32% respectively, higher than at 6 weeks. Similar trends were observed for breast and thigh meats, though the former had better quality.
