This research investigated how extracts from oyster mushrooms (Pleurotus ostreatus) can help improve vaccine effectiveness in young chickens. The study found that adding mushroom extracts to drinking water helped stimulate the immune system and increase antibody production when used alongside standard vaccines. Impacts on everyday life: – Improved vaccine effectiveness could lead to healthier poultry and safer food supply – Natural mushroom extracts offer a safe way to enhance animal immune systems – Could reduce the need for antibiotics in poultry farming – May lead to more cost-effective poultry farming practices – Demonstrates potential applications of mushroom compounds in veterinary medicine
