Abstract: In this study a 2�2 factorial arrangement was used to study the effect of sex and age on serum insulin levels in 24 growing Mexican Cuino pigs between 3 and 6 months old. There were no significant differences (p< 0.05) neither for sex � age interaction nor for sex in any measured index. Overall, Mexican Cuino pigs had 14.4 and 50.8 kg of live weigh (p< 0.001) and 9.33 and 19.26 u mL 1 of fasting serum insulin levels (p< 0.001) at 3 and 6 months old, respectively. Pearson correlation matrix revealed significant differences (p< 0.05) among age, live weigth and fasting insulin levels in the examined period of life in growing Mexican Cuino pigs. According to the present evaluation, hiperinsulinemia should be present in Mexican Cuino pigs, as it has been found in either obese conventional genotypes of pigs or genetically manipulated to be small and obese animals. This effect was accentuated as pigs aged up to 6 months life. Sex appeared to have no influence on serum status of Mexican Cuino pig insulin.
