Abstract: The aim of the present study was to examine differences in proportions of the larynx between young and adult domestic pigs. Larynges (17 piglets and 14 adults) were obtained from a slaughterhouse where pigs were routinely slaughtered. Anatomical preparation, observation, and description, as well as measurements performed using MULTISCAN image analysis, were used. In the statistical analysis, apart from the arithmetic mean (x) and the standard deviation (SD), Student's t test was used with the statistical significance at \alpha = 0.05. The results showed that a significant influence of sex was observed as far as proportions of the epiglottic cartilage (smaller in older individuals) and the arytenoid cartilage parameters (3b,c) were concerned. The influence of age was found in reference to coefficients determining distance between the back horns of the thyroid cartilage and the length of the front horn of the thyroid cartilage.
