Effect of rapeseed meal instead of soybean meal on meat quality, morphology and ileum microbial population in Japanese quail

This study investigated the effects of using rapeseed meal instead of soybean meal on meat quality, morphology, and ileum microbial population in Japanese quail using 675 Japanese quail in a completely randomized design with 9 treatments, 5 repetitions, and 15 quail per repetition. The treatments consisted of a control group fed with a corn and soybean meal-based diet without additives, as well as rapeseed meal replacing soybean meal at 25, 50, 75, and 100 percent both with and without protoxin probiotic (200 mg/kg) supplementation diets from 7 to 35 days of ages. Treatments without probiotics had no effect on quail meat pH and percentage of loss due to cooking and the rapeseed meal without probiotic had no effect on meat quality of quail (P>0.05). The treatment fed with the control treatment and the 25% rapeseed meal treatment with probiotics had the highest percentage of water retention capacity, lover loss due to cooking and higher amount of lactobacillus counted(P<0.05). The control treatments and 25% rapeseed meal had lover amount of malondialdehyde and 25, 50 % rapeseed meal treatments with probiotic had lover Escherichia coli count (P<0.05). Also 25% rapeseed meal with probiotic treatment increase villi height and decerse crypt depth compare with other treatments(P<0.05). In conclusion, this study suggests that inclusion of 25 % rapeseed meal instead of soybean meal with probiotic supplementation can positively affect meat quality, morphology, and microbial population in the ileum of Japanese quail we can use this available protein meal in the Japanese quail ration.
