In order to investigate the effects of Artichoke leaf powder and vitamin Eon performance, internal organs relative weight and some blood parameters, 240 day-old quails were assigned to four treatments including, basal diet (control), basal diet supplemented with levels of 1.5 and 3 percent of Artichoke leaf powder and basal diet supplemented with 300 mg/Kg diet vitamin E with four replicates and 15 birds in each in a completely randomized design. Birds receiving diet supplemented with vitamin E showed greater body weight gain than other treatments (P<0.05). No significant different was observed in body weight gain between birds receiving diets supplemented with Artichoke leaf powder and those birds received control diet, throughout the experiment. Birds treated with diet containing three percent Artichoke leaf powder had higher feed conversion rate (P<0.05). The concentrations of albumin and HDL were greater in blood serum of birds fed diet containing 1.5 percent Artichoke leaf powder compare to other treatments (P<0.05). According to the results of this study, using Artichoke leaf powder till three percent has no negative effect on feed intake and weight gain throughout the study (1-42 d). Inclusion of 300 mg/kg vitamin E in the diet of Japanese quail improves growth performance during the first three weeks of study.

The effect of replacing alfalfa by artichoke hay on nutrient digestibility, gas production parameters, performance and carcass characteristics of Lori-Bakhtiari lambs was studied. The lambs in control group received diet containing 30 percent alfalfa, 15 percent barley straw and 55 percent concentrate and in test group alfalfa hay was replaced with artichoke hay, completely. Dry matter intake was higher for test group lambs (P<0.05), but average daily gain and feed conversion ratio were not differed between experimental groups. Gas production rate was not differed between groups, but b fraction was higher for test group (P<0.05). Replacing alfalfa by artichoke caused to increasing digestibility of dry matter and organic matter (P<0.05). However, control diet had higher digestibility of crude protein and NDF (P<0.05). After slaughter, there were no significant differences between groups in carcass characteristics and percentage of internal organs. Results of this study showed that artichoke hay could be replaced with alfalfa hay in finishing lambs diet.

Abstract
This experiment was conducted to investigate the digestibility and fermentation parameters of diets containing flower, pod with seed and leaf of siris in sheep by two-step digestion and gas production methods. The experimental diets were including zero, 25, 50, 75 and 100 percent of Siris flower, pod ...

This experiment was conducted to investigate the digestibility and fermentation parameters of diets containing flower, pod with seed and leaf of siris in sheep by two-step digestion and gas production methods. The experimental diets were including zero, 25, 50, 75 and 100 percent of Siris flower, pod and leaf. The result showed that gas production potential of diet containing 50 percent leaf was greater than other treatments (P<0.05). Gas production rate of diet containing 75 percent flower showed significant increase compared with the other diets (P<0.05). Partitioning factor, microbial biomass, biomass efficiency were the greatest for diets containing 100 percent leaf and different levels of pod (P<0.05). Dry matter digestibility of diets including different levels of siris leaf, 50 percent siris flower and 25 percent siris pod and neutral detergent fiber digestibility of diets including different levels of siris flower and 25 percent Siris pod were higher compared to control diet (P<0.05). The lowest concentration of ammonia nitrogen was belonged to diets containing 100 percent leaf and pod of Siris (P<0.05). It could be concluded that Siris leaf, flower and pod with seed of siris can be used instaed of alfalfa in sheep diet and increase digestibility and diet ruminal fermentation.

This experiment was conducted to evaluate the effect of emulsifiers such as lecithin and bile salts onbroilers performances fed diet containing vegetable fats. 192 male Ross broiler chickens were randomlyallocated in a factorial experiment design of 3 × 2, consisting two sources of fat (four percent fatty acidsor soy bean oil) and three emulsifiers (none, one percent lecithin and 0.05 percent bile salts) incompletely randomized design with four replicates and eight birds per each. Total weight gain and feedconversion ratio was not affected by fat sources while soya oil addition to diets increased feed intake(P<0.05). Emulsifiers’ addition to diet improved weight gain feed conversion ratio (P<0.05). The lengthand width of villi in jejunum, and crypt depths in duodenum were not affected by fat sources, while, cryptdepth in jejunum and width of villi in ileum of birds fed on diets containing fatty acid were higher thanother birds (P<0.05). Addition of emulsifiers to diets increased dietary metabolisable energy (P<0.05). Inconclusion, addition lecithin or bile salts to diets containing soybean oil or its fatty acids, improved bodyweight gain and feed conversion ratio in broiler chicks by increasing in absorption area of intestine anddietary metabolisable energy.

This experiment was conducted to investigate the effects of using different levels of thyme (Thymusvulgaris L.) medicinal plant and multi enzyme (Kemine) on performance and blood biochemicalparameters of Japanese quails with 240 laying bird (6 up to 12 weeks) as a 2*2 factorial include twolevels of thyme (0 and 0.75 percent) and 2 levels of Kemine enzyme (0 and 0.05 percent) in fourtreatments, 4 replicates and 15 laying quails in each replicate in a completely randomized design.Interaction between thyme and enzyme did not have any significant effects on egg productionperformance. Whereas egg weight in birds who consume thyme, was high (P<0.05) and amounts of blooduric acid and eggshell thickness in birds who received enzyme and thyme in diets, increased (P<0.05).The overall results indicated that using enzyme and thyme in Japanese quails diets can be have positiveeffects on egg weight and eggshell thickness.
