This experiment was conducted to evaluate the effects of different levels of Artemisia Sieberi oil (zero, 100, 200 and 300 mg/kg) and antibiotic on performance and blood parameters in broiler chicken. 200 day-old broiler chickens (Ross 308) were allocated to five treatments, four replications with a completely randomized design. In total period, broilers were fed dietary Artemisia Sieberi oil at level of 300 mg/kg had higher weight gain than other experimental treatments (P<0.05). Control treatment had worse feed conversion ratio compared with broilers were fed dietary Artemisia Sieberi oil at levels of 100 and 300 mg/kg (P<0.05). The level of 100 mg/kg of dietary Artemisia Sieberi oil significantly increased the white blood cell value compared with other treatments (P<0.05). Red blood cell value significantly increased at levels of 100 and 300 mg/kg of dietary Artemisia Sieberi oils compared with other treatments (P<0.05). In this study, dietary Artemisia Sieberi oil at levels of 300 mg/kg improve broiler performance and can be considered as an alternative to antibiotic growth promoter.

In order to investigate the effect of different levels of silymarin (0, 100 and 200 mg/kg diet) onperformance, carcass characteristics, blood parameters and antioxidant status, 120 day-old chicks wereassigned to 3 treatments with four replicates and 10 birds in each in a completely randomized design.Results showed supplementation of 200 mg silymarin significantly decreased the body weight gain(BWG) in starter (P<0.05) and whole period of experiment (P<0.01) and significantly increased feedconversion ratio at starter (P<0.05), grower (P<0.05) and total rearing periods (P<0.01). Also, addition of100 mg silymarin significantly increased the carcass relative weight (P<0.01) and supplementation of 200mg silymarin significantly increased the breast relative weight (P<0.05). Furthermore, 200 mg silymarinsignificantly increased the malondialdehyde and heterophil/ lymphocyte ratio and significantly decreasedsuperoxide dismutase (P<0.05). These results showed that supplementation of silymarin in diet undernormal condition, improved the carcass and breast relative weight, but no had effect on bird’s oxidativestatus.

This study was conducted to determine the nutritional value of seaweed Gracilariopsis persica and to evaluate its utilization in layer nutrition. Metabolizable Energy and chemical composition of seaweed were measured. 100 Hy-line W-36 hens were allocated to five dietary groups with five treatment group (experimental diets containing zero, five, 10, 15 and 20 percent seaweed) and it lasted for 12 weeks. Egg production, feed intake, feed conversion ratio, egg weight and egg mass were measured weekly. The results showed that the CP, CF, EE, Ca and P of the seaweed were 23.05, 7.2, 0.1, 0.9 and 0.34 percent, respectively. Apparent Metabolizable Energy and Apparent Metabolizable energy corrected for nitrogen were 2185.04 and 2195.72 Kcal/Kg, respectively. The treatments contain more than five percent seaweed, decreased egg production and increased feed conversion ratio (P< 0.05). There was significant decrease in egg mass for more than 10 percent seaweed treatments (P< 0.05). These results showed that usage of five percent seaweed Gracilariopsis persica in the layer hens' diet doesn't have negative effect on production performances.

The effect of replacement of soybean meal protein with low glucosinolate rapeseed meal was investigated in an experiment with 320 one-week old broilers with an average live weight of 111 g. Chicks divided into two groups and each further subdivided into four subgroups. To each subgroup, four cages of 10 chicks per cage allocated. 30 and 45 percent of soybean meal protein of the diet of group (1) and group (2) replaced with rapeseed meal respectively. Levels of enzyme were zero, 500 units of phytase, 600 units Safizym GP 800 and a mixture of 500 units of phytase and 600 units of Safizym GP 800 added to the diets. Results showed that the interactions of levels of rapeseed meal and enzymes on the feed conversion and live weight gain were significant. In 30 percent replacement level, the best feed conversion (1.8) were belong to diets with no enzyme and in 45 percent of replacement, the feed conversion of diets with no enzyme (2.43) were higher than the diets with mixture of enzyme (2.03). The lowest values of live weight gain in the total period (42.30 g) was belonged to 45 percent replacement of rapeseed meal without enzyme. Overall result shown that the rapeseed meal can be used to provide 30 percent of the diet protein but in the case of adding enzyme to the diet, up to 45 percent of protein can be provided by the rapeseed meal.

This study was carried out to investigate the effects of Natuzyme Plus (a multi enzyme) in diets containing wheat and canola meal on broiler performance. A total of 336 day-old Arbor Acres broiler chicks were used in a completely randomized design with six treatments and four replicates. Experimental diets were: 1 . Diet based on corn-soybean meal (control), 2 . Diet containing 30 precent wheat and 3 . Diet containing 30 percent wheat + 10 percent canola meal, which Natozyme was added (350 g/ton) to these diets to make diets containing enzyme (totally six treatments). Adding enzyme to diet containing wheat and canola meal increased significantly feed intake, weight gain and feed conversion ratio (FCR) at starter and overall rearing period (P< 0.01). Use of Natuzyme Plus in diet containing wheat and canola meal reduced significantly the relative weight of digestive organs in compared of same diets without enzyme. The results of this study indicate that the performance of broiler chickens fed the diets containing wheat and canola meal could be improve by supplementing with Natuzyme plus preparations.

400 one day-old broiler chicks were allocated on a randomized complete design experiment with five treatments consisting of four replications for 42 days. Experiment treatments were included: 1 . based diet consist 20 percent barley (barley control), 2 . barley control + 0.1 percent of mixed essential oil (Antibiofin), 3 . barley control + 0.2 percent organic acid, 4 . barley control + 15 ppm of antibiotic (virginiamycin) and 5 . corn-soybean based diet as corn control. In addition, Basal diet supplemented with commercial enzyme preparation. There was significant difference within treatments for 42 age's body weight and FCR. No significant differences in FI were noted among treatment during experiment. Antibody titer against (SRBC) among groups in secondly immuno response had a significant effect (P< 0.05). The villus height of deudenum and Jejunum was significant differences among the treatment groups. It can be concluded that by using additives such as medicinal plant and organic acids in diets containing barley, can be achieved to similar performance of corn based diets.

The effects of phytase and glycosidase supplementation to diets containing rice bran on broiler performance were investigated by using 200 day old (308 Ross) broiler chicks in a completely randomized design with five treatments and four replicates. The five dietary treatments were as: corn-soybean meal based diet; diet containing rice bran; diet containing rice bran supplemented with Natafous; diet containing rice bran supplemented with Safizyme, and diet containing rice bran supplemented with Natafous and Safizyme. The dietary levels of rice bran were 15, 20 and 25 percent for the starting, growing and finishing diets, respectively. Birds fed on rice bran + enzyme added diets consumed less feed (P< 0.05) than those fed on unsupplemented rice bran contained diets. The enzyme addition to rice bran containing diets improved the villi length and weight gain of birds at different rearing periods (P< 0.05). In conclusion, results showed that the Natafous or Safizyme supplementation in diets could improve the performance of broiler chicks when rice bran was used at a level of 15, 20 and 25 percent in starter, grower and finisher diets, respectively.
