Abstract
Serum levels of thyroid hormones in cats are analyzed to determine the normal range in the species, and, for identifying a possible alteration either at the level of the thyroid gland or pituitary level, resulting in a high or low concentration of them. The objective of the present research was to compare and analyze the correlation between serum thyroid concentrations of four groups native-born cats or their crosses (females young vs. males young, adult females vs. adult males, females young vs. adult females, males young vs. adult males). Samples from 96 cats in the fasting state, differentiated by gender and age (46 cats under one year: 21 females and 25 males and 46 cats over one year: 21 females and 25 males) were obtained, and the levels of thyroid releasing hormone (TSH) and free tetraiodothyronine (T4L) were measured by enzymatic immunoassay. For the group of young cats statistically significant difference was found in the T4L variable with P value less than 0.05 (0.01) for a confidence of 95%, just as in group of females was found a statistically significant difference in this same variable with a P value less than 0.05 (0.03). The results shown by young females suggests high concentrations of thyroid profile with respect to young males and lower concentrations compared to adult females
