| Abstract |
The research was conducted to study the reproductive performance and some physiological parameters of Japanese quail females differ in eggshell color and pattern using image analysis. A total number of 225 five weeks-old Japanese quails (150 female + 75 male) were used. Females were classified into four groups according to their eggshell color and pattern, 1st group [Light eggs (none or rarely of very small spots)], 2nd group [Dotted eggs (small but much spots)], 3rd [spotted eggs (large but many spots)] and 4th group [dark eggs (Very large but little spots)]. Light eggshell color group had higher clutch number, pause number, pause length, hue and lightness of eggshell and lower clutch length, egg production %, egg mass from 57-84 days, antibody titer against sheep red blood cells (SRBCs) and saturation of eggshell than other groups. The dark eggs group had the highest value of plasma triglycerides and lowest of clutch number or pause number. Spotted and dark eggshell groups had the highest values of shell % and shell thickness. No Significant differences were found among four eggshell color groups in each of age at sexual maturity, egg weight from 35-140 days, egg mass from 35-140 days, albumen %, yolk%, shape index, yolk index, Haugh unit and yolk color, plasma total protein, albumin, globulin, malondialdehyde, cholesterol, total lipid, calcium and phosphorus. Positive correlations were found among the three colors, red, green or blue of Japanese quail eggshell and the hue or lightness but were negatively correlated with saturation. The correlation between saturation and lightness was negatively, but was positively between hue and lightness. Hue of Japanese quail eggshell color positively correlated with each of clutch number, pause number, pause length, and shape index but it negatively correlated with each of clutch length, egg production, egg mass, Haugh unit, shell % and shell thickness, plasma cholesterol and calcium. Saturation or Japanese quail eggshell color correlated positively with clutch length, malondialdehyde and antibody titer against SRBCs and negatively with each of clutch number, pause number, pause length, Haugh unit, shell %, plasma globulin, total antioxidant, packed cell volume and hemoglobin. Lightness of Japanese quail eggshell color correlated positively with each of clutch number and pause number but it correlated negatively with each of clutch length yolk index, Haugh unit and shell % and malondialdehyde. It can be concluded that, should be selection of' females producing spotted and dark eggshell which had better reproductive performance compared to females with light eggshell color and using image analysis in this selection.
Key Words: Quail, reproductive, eggshell color, image analysis immunity, egg quality.
