In herein study, dietary TRT1 and TRT2 significantly decreased the epinephrine, norepinephrine and cortisol concentration compared with the control group (P < 0.05). Higher piglet IgG concentration was observed in the TRT1 and TRT2 group compared with the control (P < 0.05). Dietary TRT1 and TRT2 led a lower diarrhoea score of piglets than those of the control treatment (P < 0.1). A higher piglet ADG was detected in the TRT2 (P < 0.1) compared with the CON treatment. No significant difference was observed on the rectal temperature of sows, the behaviour of the piglet and sows among treatments.
In conclusion, creep feeding can increase the immunity of piglet and decrease the diarrhoea score of piglets. A higher energy creep feeding can significantly increase the growth performance of piglet compared with the those without creep feeding, while the creep feeding with lower energy show intermediate.
