The influence of age on the basic nutritive traits of wild boar (Sus scrofa) venison

Abstract

The aim of our study was to determine the effect of age on protein, fat and water content in venison of wild boar (Sus scrofa). The sampling took place immediately after hunting, during the primal treatment of the wild boars. The musculus semimembranosus was sampled for the analyses. Monitoring of wild boar was realized in November and December 2016 in hunting region JXXVIII Tribeč (Western Slovakia, mountain range of Tribeč). Analysis of basic nutritive components of venison were determined with FoodScan LAB Analyzer (FOSS, Denmark) – NIR technology. The highest obtained average value of fat content was detected in piglets 4.45%, the lowest average value was in one year old individuals, 2.85%. There was no statistically significant difference in fat content (P˃0.05).The highest average value of protein content was found out in two years old animals and presents 23.31%. The lowest value was determined in group of piglets that reached 22.08%. A statistically significant difference was determined in protein content values (P<0.05). The lowest average value of water content was found out in the group of three years old individuals (69.87%) and the highest content, 72.47% in one year old group in the water content. There was no statistically significant difference (P˃0.05) in water content of venison. However, the age is still considered as a factor influencing the meat quality also from the point of view of human nutrition both of chemical traits.
