Abstract/ Executive Summary:

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.

Objectives:

To know the effects of four genotypes of quail on their hatchability traits, body and egg production.

Methodology:

This study was conducted with four genotypes of quail, namely Japanese (J), White (W), Black (Bl) and Brown (Br) quail maintained in Poultry Production Research Division, Bangladesh Livestock Research Institute, Savar, Dhaka. The parent males and females were being maintained in cages for single pair mating through close breeding system for producing each generation. At least five generations of pedigree hatching were done to homogenize their genetic characters. Pedigree records are being kept by using commercially available leg bands to identify quail of all ages. For producing third generation (G3), parent quails of each genotype were selected from the 2nd generation (G2) on the basis of breeding value according to their 5th week body weight. Hatching eggs were collected from every single pen of the selected parent quails. A total of 1866-day-old chicks comprising of 4 types of quail, namely J, W, Br, and Bl were hatched in a batch for producing third generation. The chicks were housed and reared in brooder house in litter system up to 5 weeks of age. Then birds were shifted to individual cages in laying house and reared up to 24 weeks of age. All birds were fed on quail starter diet up to first 6 weeks of age. Then laying diet containing 24% crude protein and 3000 kcal ME/kg were provided to the birds till to the end of study period. Farm bio-security and hygienic measures were maintained strictly to prevent outbreak of any diseases. Data on egg weight, hatchability, body weight of chick at first day, 2nd, 4th, 5th and 6th week of age, feed intake, mortality, egg production were recorded to study their productive and reproductive performances. All collected data were analyzed by general linear model (GLM) univariate procedure in SPSS Computer Program (version 11.5). Data were arranged for a completely randomized design (CRD) for analysis of variance (ANOVA). Least significant differences (LSD) for a parameter were used to calculate the significant difference among four genotypes of quail.

Achievement/Findings:

It can be concluded from the present findings that the performance of white and black quail were superior for body weight and black for egg production. So these findings deserve more attention for continuing the ongoing research for producing a suitable meat or egg type quail genotype for the country.
