الملخص EN

Twenty four Karadi male lambs, weighing 21.4 _+ 2.5 kg live weight and 4 months old were used to investigate the effect of two levels (0 and 7.5 g/kg DM) and three sources of feed additives (Nigella stiva, Rosemary and Probiotic) on daily intake (DI), live weight gain (LWG), feed conversion ratio (FCR) and some blood parameters using four diets.

Diet 1, contain none of the feed additives sources, represented one level of feed additives (0 G / kg DM) and served as the control for all additives feed diets.

Diets 2, 3 and 4 contain feed additives from Nigella sativa, (NS), Rosemary officinal (RO) or Probiotic (Pr) respectively.These diets represented the second level of feed additives (7.5 g / kg DM ).

Blood samples were taken to determine growth hormone (GH), blood sugar (BS) and blood urea nitrogen (BUN) and serum uric acid, (SUA).

There were no differences between treatments in all nutrients intake.

However, the lambs given feed additives diets gained faster than those fed control diet.

Feed additives were significantly (P<0.05) increase GH , BS and reduce BUN and SUA as compared with control diet.

However, GH of lambs received RO was significantly (P<0.05) higher than those received NS and Pr.

Lambs received NS diet was significantly (P<0.05) reduce SUA than those received RO or Pr diets.
