Performance, immune response, and meat quality in Newcastle-vaccinated quail fed with colored corn in place of yellow maize

This work investigated the effects of the usage of colored corn as a replacement for 50% and 100% yellow corn in the diet of Japanese quail. Two hundred and forty-day-old Japanese quails were indiscriminately separated into four experimental groups consisting of six replicates each containing 10 quails. Experimental groups designed: the control group (C) (basal diet-0% colored corn, vaccinated), negative control group (NC) (basal diet-0% colored corn, no vaccine), 50% CC group (basal diet-50% colored corn, vaccinated), and 100% CC group (basal diet-100% colored corn, vaccinated). At the end of the 35-day period, the highest body weight and body weight gain (BWG) were recorded in the 50% CC ( P 0.05), and the best feed conversion ratio (FCR) in the 50% CC group ( P
