The effect of medicinal plant of Cynara scolymus (artichokes) were studied on ascites syndrome, systolic blood pressure and blood parameters in broiler chickens using a total of 400 one-day-old Ross 308 in a completely randomized design with 5 treatments, 4 replicates and 20 chicks for each replicate, up to 42d under cold temperature condition. Experimental treatements were control (basal diet), antibiotic (basal diet plus 0.0015 percent antibiotic virginiamycin), aspirin (basal diet plus 0.2 percent aspirin powder) and two basal diets containing 1 and 2 percent artichoke powder. The results showed that feed intake and body weight were increased and feed conversion rate was decreased in artichoke powder received groups in comparison with other treatment (P

Abstract
The effect of dietary olive leaf in diet at different periods of breeding was studied on growth performance and ascites incidence in broiler chickens. A total of 336 one day-old male broiler chickens (Arian) used in complete randomize design with 6 treatments, 4 replications and 14 birds in each replication. ...

The effect of dietary olive leaf in diet at different periods of breeding was studied on growth performance and ascites incidence in broiler chickens. A total of 336 one day-old male broiler chickens (Arian) used in complete randomize design with 6 treatments, 4 replications and 14 birds in each replication. The period of experiment was 42 days. The rations were supplied base on recommendation of Arian broiler management guide in three phase of feeding. In each phase, tow diets were provided with 0 (control) and 1 percent of olive leaves dried in diet. The treatments were diets:1) control, 2) from 1 to 14 days olive leaf, 3) from 1 to 21 days olive leaf, 4) from 1 to 28 days olive leaf, 5) from 1 to 35 days olive leaf, 6) from 1 to 42 days olive leaf. The effects of treatments were not significant on final body weight, daily feed intake and feed conversion ratio. The mortality due to ascites syndrome was reduced in treatments of olive leaf 1 to 14 and olive 1 to 42 (P<0.05). At the end of experiment, the most of packed cell volume and hormone triiodothyronine was related to the control treatment (P<0.05). The mean of packed cell volume and T3 were significantly different between control and olive leaf from 1 to 42 days at the end of experiment (P<0.05). The difference of red blood cell count and thyroxine (T4) was not significant between all treatments. It is concluded that the inclusion of 10 g/Kg of olive leaf dried in broiler chicken diets could decrease ascites incidence without unfavorable effects on broiler chicken performance.

Abstract
Effect of L-carnitine and butyric acid on the performance and immune responses of 192 broiler chickens (Ross 308) was investigated with three levels of L-carnitine (zero, 125 and 250 mg/kg) and two levels of butyric acid (2 g/kg) in a 2×3 factorial arrangement based on randomized complete block ...

Effect of L-carnitine and butyric acid on the performance and immune responses of 192 broiler chickens (Ross 308) was investigated with three levels of L-carnitine (zero, 125 and 250 mg/kg) and two levels of butyric acid (2 g/kg) in a 2×3 factorial arrangement based on randomized complete block design with 6 dietary treatments, four replicates and eight birds per each. Broilers fed basal diet plus feed additives (L-carnitine and butyric acid) did not have significant differences on feed intake, body weight gain and feed conversion ratio when compred to control group. Broilers fed diets containing additives had higher blood lymphocyte count than control diet fed birds (P<0.05). Primary IgG tiitter (31d) against SRBC in broilers fed diet containing 125 mg/kg L-carnitine was higher than that of the control birds (P<0.05). Skin thickness in response to PHA in broielrs fed diet containing 250 mg/kg L-carnitine alone and 125 and 250 mg/kg L-carnitine in combination with butyric acid was lower than that of control group (P<0.05). It was concluded that addition of 125 mg/kg L-carnitine and two g/kg butyric acid did not influenced broiler chicken performance while improved their immune response.
