Abstract
The current experiment was conducted in the poultry field of the department of animal production at the College of Agriculture - University of Kirkuk for the period from 22/2/2024 until 4/4/2024, to study the effect of improving the nutritional value of local sunflower seed meal used in broiler diets by adding a lactic acid bacteria and its effect on production traits. 280 one-day-old, unsexed Rose 308 broiler chicks were randomly distributed into seven treatments, with four replicates for each treatment (ten birds for each replicate). The results showed Significant decrease (P ≥ 0.05) in the treatments (third, fourth, sixth and seventh) in the feed consumption rate and no significant differences in the nutritional treatments (first, second and fifth) in the weight gain rate, and in the cumulative week for the feed conversion treatment, the results showed no significant differences (P ≤ 0.05) between the treatments (third, fourth, sixth and seventh), and as for the carcass weight, the first, second, third, fifth and sixth treatments were significantly superior to the fourth and seventh treatments. The relative weight of the gizzard, the fourth treatment was significantly superior (P ≤ 0.05) to the rest of the nutritional treatments, unlike the relative weight of the breast, which showed a significant decrease (P ≥ 0.05). The results of the study showed that there were no significant differences (P≤0.05) in the relative weight of the liver, the relative weight of the heart, the relative weight of the thigh, the relative weight of the back, the relative weight of the wings, and the relative weight of the neck.
