In conclusion, turmeric supplementation increased growth performance 
compared to a control diet containing no antibiotics or zinc. Turmeric also 
decreased the response of a LPS challenge by lowering rectal temperature and 
change in TNF-α. Turmeric at 2 g/kg of the diet increased growth performance 
over 21 days and decreased rectal temperature and TNF-α during a LPS 
challenge. Therefore, further research should be conducted to study the effects 
of turmeric at 2 g/kg of the diet vs. subtherapeutic antibiotics in a commercial 
nursery setting.
