Introduction and Objective: Japanese quail belongs to Galiformes class, Phaside family, Coturnix genus and Japonica species. Maize is a high-energy grain that is the focus of most poultry producers. However, it is not always available at an economical price. In our country, wheat waste may be a more economical and easily available alternative. The higher amount of crude protein, amino acids lysine, methionine, arginine, phenylalanine, alanine, tryptophan, threonine and valine in wheat compared to corn and improving the quality of pellet in diets containing wheat are the advantages of this grain. The purpose of this research was to investigate the effects of two levels of wheat with three methods of milling and autoclaving and adding enzymes on the performance and blood metabolites of growing Japanese quails.
Material and Methods: This experiment was conducted to investigate the different levels wheat with different processing on the yield, carcass traits and blood metabolites of growing Japanese quail was performed in completely randomized design.This experiment was consisted of seven treatment, 1-control, 2-diet with %15 wheat, 3- diet with %15 wheat with enzyme, 4-diet with %15 autoclaved wheat 5-diet with %30 wheat, 6- diet with %30 wheat with enzyme, 7-diet with %15 autoclaved wheat. This study, conducted with total of 560 3-d quails that non-sex-separated consisted of 7 treatments and 4 replicates and each replicate consisted of 20 quails. The growth period for performance evaluation ranged 3-42 days.
Results: The results showed that the control and 15% wheat with enzyme treatments had higher BW and ADG at 42 days and the lowest ones was observed in the 30% wheat without enzyme treatment (P <0.05). The effect of different experimental treatments on feed conversion ratio in the period of 21 to 42 days was significant (P <0.05) so that the control treatment had the lowest feed conversion and the treatments containing wheat at levels %15 and %30 had the highest feed conversion ratio. Regarding the relative weight of breast and thigh, there was a significant difference between different experimental treatments (P <0.05) and the highest weight was related to control treatment and 15% with enzyme wheat. Different experimental treatments did not affect a significant effect at total cholesterol (P<0.05), but this trait was significantly differ between the two sexes (P> 0.05) and the female sex had higher total serum cholesterol than the male. Duodenal villi area was significantly affected by different experimental treatments (P<0.05), in the treatments containing enzyme with both levels of feed grade wheat had the highest amount in compared to other treatments.
Conclusion: It n general, it can be concluded that due to the sensitivity of this bird, at the beginning of the production period up to 3 weeks, high levels of wheat even with processing, did not included in diet,but during the growth period, can use 15% of wheat supplemented with 500 grams per kilogram of multi-enzyme.
