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.

The aim of this study was to examine the effects of Artemisia annua L. essential oil (AAEO) and probiotic (Lactobacillus acidophilus) on egg and carcass quality of laying Japanese quails. A total of 180 46-d-old female Japanese quail were randomly allocated to 4 dietary treatments in a completely randomized design with five replicates and nine birds per each. The experimental diets were: 1) basal diet as control group (without additive), 2) basal diet plus oxytetracycline (200 mg/kg), 3) basal diet plus AAEO (250 mg/kg) and 4) basal diet plus probiotic (4 CFU Lactobacillus acidophilus per kg diet). Results showed that the use of probiotic caused to an increase in the cumulative egg weight and daily egg mass, when compared with control and AAEO treatments (P<0.05). In comparison to control group, supplementing the basal diet with AAEO resulted in decreases on MDA level of egg yolk (P<0.05) and liver weight (P=0.06). In addition, the F3 and F2 follicles weights were increased when the basal diet supplemented with each of the feed additives (P <0.05). It can be concluded that, Lactobacillus acidophilus can be used as an alternative to antibiotics for increasing the egg production, and AAEO can be used to produce healthy products in feeding laying Japanese quails.

The purpose of this experiment was to examine the effects of Artemisia Annua L. essential oil (AAEO) and probiotic (lactobacillus acidophilus) as an alternative to antibiotic in feeding laying Japanese quails. A total of 180 46-d-old laying Japanese quails were randomly allocated to 4 dietary treatments in a completely randomized design with 4 replicates of 9 birds, and the experiment lasted up to 109 days of age. The experimental diets were: 1–basal diet as control group (without additive), 2–basal diet plus oxytetracycline (200 ppm), 3–basal diet plus AAEO (250 ppm) and 4– basal diet plus probiotic (4 CFU per kg diet). Results showed that the use of probiotic caused an increase in the egg mass, when compared with control and AAEOtreatments at entire period (P<0.05). The groups fed probiotic and AAEO showed a significant decrease in the serum glucose, cholesterol and LDL levels when compared with those fed antibiotic (P<0.05). Moreover, the group fed AAEO had low lymphocyte and high heterophil counts when compared with those fed diet supplemented with probiotic and antibiotic (P<0.05). In addition, the number of white blood cells and heterophil/lymphocyte ratio in AAEO group were higher than other groups (P<0.05). It can be concluded that lactobacillus acidophilus could be used as a growth promoter in feeding laying Japanese quails.
