One 2×2 factorial design trial was conducted to determine the effects of drinking water temperature (DWT: 11 or 30 ℃) and environmental enrichment (EE: no addition or addition) on performance and nutrients utilization in weaned piglets for 40 days. One hundred 30-day-old weaned piglets were randomly divided into control (DWT11-EE), warm water (DWT30-EE), EE (DWT11+EE), warm water and EE (DWT30+EE) group, and each group with 5 replicates of 5 pigs (3 boars and 2 gilts). The results showed that: (1) with EE drinking, 30 ℃ water significantly increased average daily water intake by 23.4% (P<0.05); DWT significantly decreased F/G (P<0.05); DWT and EE had marked interactions on average daily feed intake (ADFI) and average daily gain (ADG) (P<0.01); (2) DWT increased the apparent digestibility of phosphate (P) significantly (P<0.05). DWT and EE had significant interactions on the apparent absorptive amount of dry matter (DM), CP, ether extract, Ca and P (P<0.01). It was concluded that drinking 30 ℃ water increased feed conversion ratio and average daily water intake in the weaned piglets, and that drinking 11 ℃ water was suitable for weaned piglets with EE and drinking 30 ℃ water was suitable for weaned piglets without EE.［Chinese Journal of Animal Nutrition, ２００9，２1（5）:640-644］
