The effect of different levels of Lavender essential oil and bacitracin methylene disalicylate supplementation on performance, carcass traits, some blood parameters, small intestinal morphology and microflora in Japanese quails

In order to investigate the effect of different levels lavender essential oil and bacitracin methylene disalicylate antibiotics on performance, carcass traits, some blood parameters, small intestinal tissue morphology microbial population in Japanese quails, a study was performed 400 pieces quail per day. The treatments included group consuming basic diet without any additives as (control) antibiotic (0.25g.kg) 3 (150, 200 250 ppm) kg feed form completely randomized design with 4 replications 20 birds ( male female) each replication. this experiment daily weight gain, intake, conversion ratio, final live weight, relative breast, thigh, gingival, liver, were examined. results showed that use increased intake quails. weeks experimental period an increase quails compared control group. addition, general, ratio using oils decreased during breeding periods. show slight decrease percentage body liver empty breasts, thighs carcasses studied under influence antibiotics. Serum albumin significantly (P≤0.05). highest serum globulin level affected by at ppm also HDL Additionally triglyceride LDL due consumption Intestinal there no statistically significant difference changes width, length, height mucosal muscle Ecoli colonies number Lactobacillus bacterial obtained from usefulness by-products traits morphological parameters
