| Abstract | ||
| This study was carried out at the poultry farm of the College of Agriculture, University of Tikrit aiming to inhancing the nutritional value of local grass pea used as replacement of soybean meal using enzymes or and probiotic in broiler diet, 810 day old chicks randomly distributed in to nine treatments and each treatment sub divided in to three replicates (30 chicks per replicate) and the treatments were: (T1): Control diet free of grass pea seed or enzymes or probiotic, (T2): replacement 33.3% of soybean meal protein with protein of grass pea. (T3): replacement 66.6% of soybean meal protein with protein of grass pea seed. (T4): T2 diet and adding 0.4% of probiotic. (T5): T3 diet and adding 0.4% of probiotic. (T6): T2 diet and adding 0.1% enzymes. (T7): T3 diet and adding 0.1% enzymes. (T8): T2 diet and adding 0.4% of probiotic and 0.1% enzymes. (T9): T3 diet and adding 0.4% of probiotic and 0.1% enzymes.Results indicated: No differences in the average live body weight and cumulative weight gain (1- 49 days) when replacing 33.3% of soybean meal protein with protein of grass pea (T2) and adding probiotic (T4) and adding enzymes (T6) or adding probiotic with enzymes (T8) compared with control treatment (T1), when as increasing replacement to 66.6% of soybean meal protein with protein of grass pea (T3) and adding probiotic (T5) or adding enzymes (T7) or adding probiotic with enzymes (T9) causing significant (P<0.05) decreases in live body weight and weight gain (from 1-49 days) compared with control treatment (T1). No significant differences in feed intake and feed conversion when replacing 33.3% of soybean meal protein with protein of grass pea seed (T2) when probiotic was added (T4) or enzymes (T6) or adding probiotic with enzymes (T8) compared with control treatment (T1). when as increasing replacement to 66.6% (T3) with adding probiotic (T5) or adding enzymes (T7) or adding probiotic with enzymes (T9) caused an increased in these objects significantly (P<0.05) compared with control treatment. No differences in mortality percentages were noticed due to replacing soybean meal protein with grass pea with or without probiotic or enzymes or both. | ||
