The objective of this study was to determine the effects of green tea probiotics on growth performance, meat quality
and immune response in finishing pigs, and to assess the possibility of substituting green tea probiotics for antibiotics in diets of
finishing pigs. This green tea probiotics is made by mixing green tea powder and excipients (defatted rice bran and wheat bran) and
fermenting the mixture with beneficial bacteria. A total of 90 crossbreed “Landrace×Yorkshire” finishing pigs with an average body
weight of 72.5±2.5 kg were assigned to 5 dietary treatments in a completely randomized design. Each treatment had 3 replications with
6 pigs per replication. The five dietary treatments were control, antibiotic (0.003% chlortetracycline added) and 0.1, 0.5 and 1.0% of
green tea probiotics. There were no significant differences in final body weight, daily weight gain, daily feed intake and feed conversion
ratio in the green tea probiotics and antibiotic treatments (p>0.05). Crude protein content was significantly increased in the 0.1 and 1.0%
green tea probiotics treatment groups (p
