Authors have studied the effect of variation of environmental temperature, especially of high temperature, on the growth of piglets. This study was conducted to clarify the effect of fixed high environmental temperature on the growth of piglets. Three experimental groups were established for the different temperature: fixed at 21, 27 degree C and 33 degree C. Present experiment was repeated twice for the parturition of frood saw. Six female piglets of crossbred Y (middle york) X W (large white) and 17 male Y strain piglets were used in this study. They were distributed to each group as a same mean value of body weight. This experiment was finished at the time when one of the piglets used grew up to 25 kg. Feed and water were given ad libitum over the period of growth test. Means of daily gain, daily feed intake, feed conversion and body temperature were determined and the data expect body temperature were corrected by the statistically treatment. Daily gain of the 33 degree C group was significantly lower than those of the other two groups (21 degree C and 27 degree C). Daily feed intake of the 33 degree C group was significantly lower than that of the 21 degree C group but that of 27 degree C group showed no significant difference for the other two groups. As the results, high environment temperature condition did not affect to the body temperature, but it affected to the body weight gain and feed intake. Especially the 33 degree C condition affected to the feed conversion apparently. it seemed that the high environmental temperature condition affect to the energy metabolism of piglets, therefore the further examination of this point is required in future work
