Effects of quail genotypes on hatchability traits, body weight and egg production

Abstract

A study was conducted with four genotypes of quail, namely Japanese (J), White (W), Black (Bl) and Brown (Br) quail with the objective to know their hatchability traits, body weight and egg production performances. The parent males and females were maintained in cages for single pair mating through close breeding system for producing each generation. A total of 1866-day-old chicks comprising of 4 types of quail namely J, W, Br, and Bl were hatched in a batch. The egg weight were 10.35 ± 0.3, 11.60 ± 0.42, 10.30 ± 0.42 and 9.78 ± 0.65 for J, W, Br and Bl respectively, which was influenced (p < 0.05) by genotype. White genotype of quail is significantly better for egg weight, chick weight and chick: egg ratio than that of their counterparts. The highest hatchability of incubated eggs was found in Japanese quail genotype (71.01%) and the lowest in Black (31.03%). Significantly higher body weight was found in White and Black followed by Brown and Japanese quail genotype at different period of age. Significantly more number of eggs was obtained in Black (97.31) followed by Japanese, Brown and White respectively DOI: http://dx.doi.org/10.3329/jbas.v38i2.21346 Journal of Bangladesh Academy of Sciences, Vol. 38, No. 2, 219-224, 2014

Effects of transportation and storage duration of Japanese quail eggs on hatchability

“…Those values were higher than the present findings. On the other hand, for white, black and brown Japanese quail genotypes, Islam et al (2014) reported chick weight to egg weight ratios of 62.7%, 62.9%, 58.2% and 46.4%, which are lower than in the present study. This trait was reported as 66.9% by Dere et al (2005); as 64.5%, 62.8% and 66.5% for light (8.91 g), medium (9.80 g) and heavy (10.76 g) egg weight groups, respectively, by Adeyanju et al (2014) and as 69.4% by Alasahan et al (2016).…”

Alterations in plasma constituents, growth and egg production traits due to selection in three genotypes of Japanese quail

“…The LSG 28 genotype was the fastest for SLG, GRBW and GRSL as compared with other genotypes. Significant effect of genotype on BW in Japanese quail is also in agreement with previous reports (Islam et al 2014;Hussain et al 2016) and SL (Grunder et al 1983;Dikmen & Ipek 2006). Mohammad (2016).…”

“…Japanese quail are used widely as a model in breeding, physiology, nutrition, pathology, reproduction and immunology research (Huss et al 2008). Recently, quail rearing for commercial egg and meat production has become popular because of rapid economic returns from commercial quail production (Islam et al 2014).…”
