“…(Su et al, 2021). Additionally, licorice (Glycyrrhiza glabra) essential oil at the recommended level (200 mg/kg) not only improved thyroid hormones but also reduced E.coil in the GI tract leading to better growth performance (Geravand et al, 2021). Broilers under temperature stress received a blend of EOs in drinking water, resulting in a decrease in liver weight and increase in abdominal fat.…”

The objectives of this work were 1) to study the preparation and characterization of microencapsulated basil oil (MBO), 2) to determine the stability of MBO against simulated gastrointestinal tract and storage 3) to investigate the antimicrobial and antioxidant properties of MBO and 4) to evaluate the supplementation of MBO on growth performance, antioxidant status, ileal digestibility and intestinal morphology in broiler chickens. The present work demonstrates the use of double-layered polymers (chitosan, CS and sodium alginate, SA) with opposite charges leading to a dual pH responsiveness. The double-layered microcapsule was studied on physicochemical characteristics, the swelling performance as well as the release efficiency and the antioxidant and antimicrobial stabilities under the storage. A total of 288 one - day - old female broilers (Ross 308) were randomly allocated into 4 groups (6 replicates of 12 birds), based on a completely randomized design. Dietary treatments were (i) basal diet (NC), (ii) basal diet with avilamycin at 10 ppm (PC), (iii) basal diet with free basil oil (FBO) at 500 ppm, and (iv) basal diet with MBO at 500 ppm, respectively. Fourier transform infrared (FTIR) and thermogravimetric analyses (TGA) proved successful loading of BO in CS-SA and improved its thermal stability. Swelling showed great performance, whereas CS-SA displayed the cumulative release of BO in gastric stage (63.3 ? 4.6%) and in intestinal stage (86.8 ? 4.4%), respectively. CS-SA retains the antioxidant and antimicrobial activities of BO under storage in addition to a great tolerance of acids, bile, trypsin, including the thermal conditions. MBO improved average daily gain (ADG), and feed conversion ratio (FCR) of broilers throughout the 42-d trial (P < 0.05). The broilers fed MBO diet exhibited a greater AID of crude protein (CP) and gross energy (GE) compared with those in other groups (P < 0.05). Lactobacillus spp. and E. coil populations were not affected by feeding dietary treatments. Both FBO and MBO had positive effects on jejunal villus height (VH), villus height to crypt depth ratio (VH:CD) and villus surface area (VSA) of broilers compared to NC and PC groups (P < 0.05). Superoxide dismutase (SOD) level in the duodenal mucosa of MBO group was significantly increased (P < 0.01), whereas malondialdehyde (MDA) level was significantly decreased (P < 0.01). The concept of double-layered polymer in microcapsule form could be considered as a promising driver of the BO efficiency, consequently MBO could be potentially used as a feed additive for improvement of intestinal integrity and nutrient utilization, leading to better performance.

BackgroundVitamin D possesses an important role in the maintenance and health of broiler chickens. Herbal essential oils (EOs) have been proposed as a suitable alternative to chemical drugs in intensive production management systems for better performance of broilers with slight side effects and admirable therapeutic properties.ObjectivesThis experiment was conducted to investigate the effects of feeding cholecalciferol (VD) in combination of Satureja rechingeri EO (SREO) on growth performance, haematological indicators and immunological response of broilers.MethodsA total of 540 1‐day‐old mixed‐sex broiler chickens (Ross 308) were used in a completely randomized design with a 3 × 3 factorial arrangement of treatments. Experimental treatments included different concentrations of cholecalciferol (VD) (0, 2000 and 4000 IU/kg = 0, 0.05 and 0.1 mg/kg) and SREO (0, 200 and 400 mg/kg) on growth performance, haematological indicators and immunological responses of broiler chickens were investigated.ResultsThe results showed that the chicken fed diet supplemented with 0.1 mg/kg VD (VD0.1) in combination of 200 mg/kg SREO (SREO200) increased the feed intake during the overall and first 14‐day periods of the trial when compared with other dietary treatments. Interaction of VD0.1 × SREO200 led to more body weight gain (BWG) in the grower and finisher phases than all other feed treatment groups. The blood level of lymphocyte at day 42, heterophil at days 28 and 42 and heterophil/lymphocyte (H/L) ratio at 14 and 28 days of age were affected by VD0.1 + SREO200 in comparison with VD0 + SREO0 group. Feeding VD and/or SREO decreased triglyceride, cholesterol and low‐density lipoprotein concentrations at days 28 and 42 of the study, especially in VD0.1 + SREO200 treatment. Feeding VD0.1 + SREO200 also resulted in higher serum status of immunoglobulin M, lysozymes and phagocytic percentage among all treatments.ConclusionConsidering the outcomes, it is suggested that the combination of suitable concentration of VD and EO of the plant had favourable effects on the immune system and performance criteria of broiler chickens.
