n = 5: there were five replicates (pens) per treatment and six piglets per pen, and one piglet per pen was sampled.
2
Con: the control diet supplemented with 25 mg/kg quinocetone and 11.25 mg/kg chlortetracycline in the basal diet.
3
Treatments: the treatment diets supplemented with 200, 400, or 600 mg/kg bacteriophage in the basal diet.
