The objective of the present study was to evaluate and compare the in vitro cecal fermentation (by the gas production technique), in hairless Mexican pig and Asian pig, adding cellulose or starch as a substrates (0, 100, 200, 30 and 400 mg/ g DM). 12 pigs were slaughtered ( BW= 104±0.5 kg), six of each genotype, and after that take cecal content of each one, and it was made a pool using two pigs per genotype; after that per substrate (cellulose or starch) in each concentration, it were incubated in three flasks per pool with inoculums and it made three incubation series. The experimental design use the effect of genotype, substrate and concentration of the substrate added on the variables of in vitro fermentation. The averages of the data were compared by turkey’s method. In vitro gas production was higher (P
