A study was conducted to evaluate growth performance and egg production traits of Japanese quails fed diets containing different supra-nutritional levels of vitamin E and C (600, 800 and 1000 mg/kg). A completely randomised design was adopted and main effects (vitamin E and C) were arranged in a 3 x 3 factorial approach. Throughout the study (42 to 105 d), the highest feed intake (vitamin C, p = .01) and weight gain (vitamin E x C, tendency p = .06) were obtained with vitamin E and/or C at 800 mg/kg whereas the highest dietary efficiency with 600 mg/kg of vitamin E plus 600 or 1000 of C and with 800 mg/kg of E plus 600 or 800 mg/kg of C (vitamin E x C, tendency p = .06). The highest final body weight was achieved with 1000 mg/kg of both the vitamins (vitamin E x C, p = .02). Vitamin E and/or C at 1000 mg/kg increased egg production, weight of produced eggs (vitamin E x C, p = .04), number of produced eggs to feed ratio, weight of produced eggs to feed ratio (vitamin E and C, p < .01), average egg volume (vitamin E x C, p = .03), and egg shape index (vitamin E, p < .01; vitamin C, p = .01). Current findings showed that feeding vitamin E and C at supra-nutritional levels can be a good management practice in Japanese quail nutrition to promote growth performance and egg production traits under thermoneutral condition.

Abstract

A study was conducted to evaluate growth performance and egg production traits of Japanese quails fed diets containing different supra-nutritional levels of vitamin E and C (600, 800 and 1000 mg/kg). A completely randomised design was adopted and main effects (vitamin E and C) were arranged in a 3 x 3 factorial approach. Throughout the study (42 to 105 d), the highest feed intake (vitamin C, p = .01) and weight gain (vitamin E x C, tendency p = .06) were obtained with vitamin E and/or C at 800 mg/kg whereas the highest dietary efficiency with 600 mg/kg of vitamin E plus 600 or 1000 of C and with 800 mg/kg of E plus 600 or 800 mg/kg of C (vitamin E x C, tendency p = .06). The highest final body weight was achieved with 1000 mg/kg of both the vitamins (vitamin E x C, p = .02). Vitamin E and/or C at 1000 mg/kg increased egg production, weight of produced eggs (vitamin E x C, p = .04), number of produced eggs to feed ratio, weight of produced eggs to feed ratio (vitamin E and C, p < .01), average egg volume (vitamin E x C, p = .03), and egg shape index (vitamin E, p < .01; vitamin C, p = .01). Current findings showed that feeding vitamin E and C at supra-nutritional levels can be a good management practice in Japanese quail nutrition to promote growth performance and egg production traits under thermoneutral condition.
