Sara Kamal, Gihan Elmoghazy, Madiha S. Ibrahim.

The aim of this study was to compare the effect of different dietary supplements, probiotic (pro), prebiotic (pre), and symbiotic (pro + pre) on the productive performance of broiler chicks. A total of 504 one -day old chicks were divided into 9 dietary treatments with 7 replicate cages per treatment and 8 broiler chicks per cage. The control group (Gp1) had no supplementation. Broiler chicken were given a dose of 1ml of the different treatments at the 3rd day of age; Lactobacillus acidophilus (LBA) (Gp2), LBA and Yeast cell wall (YCW) (Gp3), Enterococcus feaceum (EF) (Gp4), EF and YCW (Gp5), Bacillus subtilis (BS) (Gp6), BS and YCW (Gp7), YCW (Gp8) and LBA+ EF+ BS+ YCW (Gp9). Body weight, body weight gain, feed intake, and food conversion ratios were calculated weekly until the end of the experiment. The results revealed that the symbiotics significantly increased the performance of the broiler chicken (p≤ 0.05).
