Abstract
This systematic review evaluated the effects of various essential oils on the survival rate, fecalysis, hematology, and blood biochemistry of Philippine native chickens. A total of twelve experimental studies conducted by agriculture students from Central Philippine University in 2024 were included. The essential oils investigated-derived from Rosemary, Eucalyptus, Turmeric, Moringa, Hauili, Guava, Galangal, Jatropha, Lemon, Betel, Oregano, and Neem-were administered orally alongside virgin coconut oil. Across all treatments, essential oils were found to be safe, with no reported mortality or acute toxicity. Several oils, particularly Neem, Hauili, Guava, Jatropha, Lemon, and Galangal, demonstrated significant anthelmintic activity by reducing or eliminating parasitic eggs in fecal samples. Hematological analysis revealed improvements in immune response and erythropoiesis, with increased white and red blood cell parameters in many treatments. Biochemical findings showed varied responses, with Moringa and Turmeric essential oils notably improving liver function and metabolic markers, while Hauili, Galangal, and Jatropha raised potential concerns for liver and kidney stress at tested doses. Overall, the findings support the potential of plant-derived essential oils as sustainable alternatives to synthetic drugs in poultry production. Further research is recommended to refine dosage, ensure long-term safety, and evaluate economic viability for broader application in organic poultry farming.
