The effect of sweet wormwood essence (SWE) and Lactobacillus acidophilus on performance, ileal microbiology, ileal morphology and ileal nutrient digestibility of laying Japanese quails was investigated in 180 46-d-old female Japanese quail that were randomly allocated to 4 dietary treatments in a completely random design with 4 replicates and 9 birds per each. The experimental diets were as follows: basal diet as control group (without additive), basal diet plus Oxytetracycline (200mg/kg), basal diet plus SWE (250mg/kg), and basal diet plus lactobacillus acidophilus (4 cfu per kg diet). Results showed that the use of Lactobacillus acidophilus increased the egg mass per hen-housed compared to control and SWE treatments (P<0.05). The number of lactobacilli in the ileal digest was also significantly increased by Lactobacillus acidophilus and SWE treatments, when compared with control treatment (P<0.05). In addition, birds fed with diets containing Lactobacillus acidophilus and Oxytetracycline showed a significant increase in villous height and villous height:crypt depth, when compared with those on the control diet (P<0.05). It can be concluded that the use of Lactobacillus acidophilus as an alternative to antibiotics is more appropriate than SWE.

This experiment was conducted to evaluate the effects of physical form, barley variety and enzyme addition on Ileal digestibility, apparent metabolizable energy (AME) and energy efficiency of broiler chickens.The experiment was carried using a factorial experiment with a completely randomized desiegn. Factors were barley varity (Fajr, Reyhaneh, and Yosef), diet form (mash or pellet) and enzyme level (0 and 0/05 g/kg dry matter). Here 927 one day-old Ross 308 broiler chickens were assigned to 12 treatments, 3 replicates and 27 chickens in each replicate. The results of experiment indicated that the digestibility of nutrients, AME, apparent metabolizable energy corrected to zero nitrogen retention (AMEn) and energy efficiencies (NE/AMEn) affected by barley variety (p <0/05). Net Energy (NE) affected by main and interaction effects (P < 005). Diets containing Ryhaneh barley variety in comparison with other varietys, increased Ileal Digestibel Protein (IDP), Ileal Digestibel fat (IDF), NE, AME and AMEn (P <0/05). Although pelleting decreased Ileal Digestibility of nutrients (p>005), NE, AME and AMEn (p <0/05), addition of enzyme to diet increased this indicators (P <0/050). According to these results, the use of pellet diet containing Ryhaneh variety with enzyme improved digestibility and energy efficiency and thus it's recommended to be used in poultry nutrition.
