Abstract

Cilj ovog diplomskog rada bio je utvrditi klaoničke pokazatelje trupa i fizikalne karakteristike prsnog mišića (m. pectoralis major) muških i ženskih jedinki divlje patke gluhare iz nizinskog područja Republike Hrvatske. Ukupno je ispitano 25 odstreljenih pataka na dva različita lokaliteta. Utvrđivane su mase svake jedinke i obrađeni trupovi te je desni prsni mišić zamrznut na -20ºC za potrebe određivanja boje mesa, pH vrijednosti, kala odmrzavanja, kala kuhanja i otpora presijecanju. Podaci su statistički obrađeni u programskom paketu SAS V9.4. Utvrđen je značajan (p<0,05) utjecaj lokaliteta odstrela na muške i ženske jedinke. Analizirajući utjecaj spola na klaoničke pokazatelje trupa, utvrđena je značajno (p<0,05) veća masa trupa, kože s perjem, očišćenog trupa i donjih dijelova nogu muških jedinki u odnosu na ženske jedinke. U vrijednostima fizikalnih pokazatelja kvalitete mesa divlje patke gluhare između spolova nisu utvrđene značajne razlike.

Abstract (english)

The aim of this master thesis was to determine the slaughter traits of the carcass and the physical characteristics of the pectoral muscle (m. pectoralis major) in male and female mallards found in the lowland area of Croatia. A total of 25 ducks killed in two sites were examined. The weight of each individual was determined, the carcasses were processed, and the right pectoral muscle was frozen at -20ºC for the purposes of determining meat color, pH value, thawing loss, cooking loss and cutting resistance. The data were statistically processed using the SAS V9.4 software package. A significant (p<0.05) influence of the killing site on male and female individuals was found. The analysis of the influence of sex on slaughter traits of the carcass showed a significantly (p<0.05) higher mass of carcass, skin with feathers, cleaned carcass and lower legs in males compared to females. No significant differences between the sexes were found with regard to the values of the physical characteristics of mallard meat quality.
