The objective of this study was to evaluate the effect of creep models for heating and piglet performance. Model 1 (MOD 1), consisted of eight creep of masonry, electrical resistance heating built into the floor and lighting with fluorescent lamps of 7 W. Model 2 (MOD 2), consisting of eight creep of wood and heating by 60 W incandescent lamp The data of temperature and humidity were recorded from birth to 26 days of life and litter, the average litter weight was obtained on the second day and on day 21 of life. The statistical model for repeated measures using the MIXED of SAS (2002-2003) was used. We tested the effects of model, week and interaction. Creep MOD 1 got an average of 20.75% of the temperature data within the thermal comfort during the experimental period in relation to MOD 2. Only the first two weeks the MOD was better with 26.04%, while the MOD 1 was 3.90%. MOD 1 litters had higher final weight of 13.80% compared to litter the MOD 2. We conclude that the MOD 1 achieved the best results related to the environment and average weight gain of litters.
