| Abstract | ||
| This study was conducted to investigate the effect of the inclusion of thermal white shaving protein (TWSP) and acidic white shaving protein (AWSP) in the diets of Japanese quail on growth performance and some physiological parameters. A total number of 315 unsexed Japanese quail chicks at 7th days of age were randomly distributed in a complete randomized block design into 7 dietary treatments of 45 birds each, with three replicates containing 15 birds each. Treatment 1 was fed a control diet, while treatments from two to seven were fed diets containing TWSP and AWSP at levels of 8, 10, and 12% of the total protein in the rations. The groups that fed a diet with 10, 8, and 12% TWSP and 8% AWSP showed higher body weight and body weight gain than the other dietary treatments or the control group (P ≤ 0.05). However, there was a significant (P ≤ 0.05) increase in blood constituents, except for PCV%, due to the addition of TWSP and AWSP in the diets compared to the control group. Although the weight of lymphoid organs decreased due to the inclusion of TWSP and AWSP, the immune response was higher in the treatment groups (P ≤ 0.05) than in the control group. Compared to the control group, the best economic efficiencies were observed for the birds-supplemented diets inclusion of TWSP and AWSP. In conclusion, the addition of TWSP and AWSP was completely safe without adversely affecting productive performance, physiological parameters, immunity, and economic efficiency. | ||
