Review:Impact of tea extract and antimicrobial effects on Newcastle disease

In recent years, we have had a serious problem with bacterial and viral diseases in poultry. Every day, ۲۰۲ million chickens are consumed worldwide using artificial medicine that may improve bacterial resistance and force us to control resistant species. Therefore, looking for natural substances that have shown great antimicrobial properties is important nowadays. Research has shown that tea extract has been able to improve the immune system with antimicrobial properties.In this experiment, black, white, and green tea extracts were used. ۲۶ groups of ۹-day-old embryonated eggs were inoculated with different concentrations of plant extracts during the investigation. Antiviral activity was observed in the extracts. One of the most common ways of inoculating the vaccine is through the eye, intranasal, and oral routes. The collected plants were washed ۲-۳ times with distilled water, dried and powdered. Then, a sample of ۲۰ grams in ۲۰۰ ml of liters was extracted with acetone, ethanol, chloroform, and hexane.The results of this research showed that the use of antimicrobial properties of tea shows a good effect at controlling Newcastle disease. In the future, we can expect to see fewer losses in poultry with the optimal use of tea powder
