Introduction and Objectives : The use of oilseeds in poultry feeding is accepted as a management strategy to reduce feed costs, which is often used in Europe, Australia and Canada. In our country, poultry diets are mainly composed of corn and soybean meal. Considering that few studies have been published regarding the effects of using whole grains along with corn and soybean in poultry nutrition; Therefore, in order to reduce the anti-nutritional effects of full-fat soybean using protease enzyme, the above study was conducted and the effect of full-fat soybean on performance, carcass characteristics, meat quality and intestinal morphology was investigated in Japanese quail.
Materials and Methods: To conduct the experiment, 480 male and female quail chicks were used in the form of 8 treatments with 4 replications, in which 15 quails were randomly placed in each replication. The experimental period was from the age of 3 to 45 days. In this research, a factorial experiment using a completely randomized basic design was conducted and the quails were treated with 4 levels (zero, 4.25, 8.5 and 12.75%) of Full-fat soybeans and 2 levels (zero and 500 mg/kg) of multi-enzyme.
Results: The obtained results showed that different levels of full-fat soybean and multi-enzyme had no significant effect on weight gain, feed consumption and food conversion ratio in the whole period (p<0.05). The percentage of cookable carcass was significantly higher at the level of 8.5% full-fat soybean than other levels (p<0.05). The length of the duodenum was obtained as a result of consumption of 12.75% of full-fat soybeans significantly more than other treatments. Meat quality indicators and malondialdehyde in the period of 30 and 90 days after storage in the freezer and water storage capacity were significantly affected by experimental treatments (p<0.05); At time 30, the amount of malondialdehyde and at time 90, the acidity of breast meat were significantly affected by different levels of high-fat soybean consumption.
Conclusion: In general, the addition of full fat soybean supplemented with protease improved the growth performance and carcass characteristics in broiler diets
