  Background and Objective: Transportation causes a high level of stress in cattle. Stress is in terms of blood parameters, growth rate, prone to get diseased and mortality. The present trial aimed to reduce the stress level and death in calves occurred during transportation. Materials and Methods: Natural Oil Blend Formulation (NOBF) was designed and developed by combining the natural oils having immunomodulating and stress-releasing properties. The NOBF applied to claves before and during transportation. The NOBF feed was prepared by mixing 2 kg of NOBF in the regular meal. A total of ten weeks trial was performed on 24 Brahman breeds of the calves. The growth performance was recorded in the form of ADG and FCR. Blood parameters were tested before, during and at the end of the experiment to determine the stress level and health conditions. Data analysis performed using SPSS software. Results: The application of NOBF had enhanced productivity and improved the calves' blood parameters during the transportation and rearing period. The diet of NOBF significantly affected final body weight on day 122. However, it did not affect daily gain (p>0.05). The calves in NOBF treated group obtained 7.78% (12 kg) (p<0.05) higher body weight gain as control during the rearing period. The increase in growth rate had a direct impact on economics, i.e., IDR 540,000 per herd compared to control. Conclusion: The obtained results showed that the application of Natural Oil Blend Formulation (NOBF) supplement had worked significantly reducing the stress in transported calves, which resulted in better blood parameters, better productivity and ultimately higher income.

  Background and Objective: Avian Infectious Bronchitis Virus (AIBV) is a highly infectious pathogen of chicken. There is no medication and vaccine developed yet due to its highly mutable nature. The objective was to formulate a blend that can be effective against the viral infection in chicken. Material and Methods: Several natural essential oils, like, Gardenia jasminoides, Commiphora myrrha, Boswellia serrata, Foeniculum vulgare and Daucus carota with anti-viral properties were blended and tested against Avian Infectious Bronchitis Virus H120 (AIBV H120) strain using in vitro medium. The trial was conducted in an allantoic fluid medium. Different concentration of NOB was inoculated into the allantoic-fluid to challenge with the lethal dose of virus. Results: The Natural Oil Blend (NOB), at its minimum concentration up to 0.01 mL of 0.1%, was effective against the AIBV H120 strain. The NBO concentration lower than 0.1% was not sufficient to deactivate the AIBV H120 strain. The embryos up to 0.1% of NBO treated groups and negative control embryos were alive and tested negative to AIBV H120 strain, whereas the embryos in positive control died and tested positive. Conclusion: The in vitro trial proven that the essential oil Blend can deactivate the Avian Infectious Bronchitis Virus H120 (AIBV H120) in in vitro medium.
