Effect of Heat Treatment of Full-Fat Soybean by Extruder on Carcass Yield and Measurements of Internal Organs in Broilers.

Abstract

 The study aims to determine the effect of using full-fat soybeans (FFSB) processed with an extruder, at different temperatures, on the carcass yield and internal organs in the broiler. using (400) chicks of hybrid Ross (308) distributed into eight groups. Feeding diet that include full fat soybeans processed at different temperatures starting from (0) ° C, (90-100) ° C, (100-110) ° C, (110-120) ° C, (120-130) °C, (130-140) °C, (140-150) °C, (150-160) °C. The results showed a significant improvement (p<0.05) in the specifications of carcasses when soybean was treated with extruder, especially within the degree (130-140) °C for both dressing and chest weight; And within (140-150) ° C for the thigh. The relative weight of the intestine and pancreas is also affected and to a lesser extent the liver, with significant differences ( p<0.05 ) and a negative correlation with the change of PH and the increase in the treatment temperature while the spleen has no effect with the same treatment and no significant (p>0.05 ), which leads us to suggest that it is considered as vital evidence of the quality of the treatment that can be added to other tests that are done outside the body in the laboratory.
