الملخص EN

An experiment was carried out using (350) one day-old broiler non sexed chicks of commercial line available in Syria to investigate the effect of full sumac seeds powder and sumac seeds powder without nucleus on Live Body weight and Feed conversion ratio in Broilers at 42 days age.

The birds were distributed into 7 the groups (50 / each).

Rearing period was divided into 2 stages according to nutritional requirements mentioned in NRC, 1994.

The First one from 1 to 21 days and the second from 22 to 42 days.

Seven diets were prepared according to the group numbers including control group without any additive (First group).

Full sumac seeds powder were added to diet with levels (0.2%-0.4%-0.6%) respectively to groups (2nd -3rd -4th), and sumac seeds powder without nucleus were added to diet with levels (0.2%-0.4%-0.6%) respectively to groups (5th-6th-7th) respectively.

The results demonstrated an increase in average live body weight with high significant difference (P≤0.01) in the birds fed sumac seeds powder without nucleus in levels (0.6-0.4)% in groups (7th-6th) respectively compared to control one (1st group) superiority rates reached (7%-5%) respectively at 42 days age.

Feed conversion ratio was better clearly by the addition of sumac seeds powder in both types compared to the control (1st group birds) especially in the seventh group and the sixth group of birds of birds (0.6% sumac seeds powder without nucleus) and (0.4% sumac seeds powder without nucleus) and the forth group of birds (0.6% full sumac seeds powder) (1.72-1.75-1.78) respectively
