Effect of weight, sex and hunting period on fatty acid composition of intramuscular and subcutaneous fat from wild boar

Abstract

The study examined the influence of weight, sex and month of hunting on the fatty acid composition of intramuscular and subcutaneous fat from 49 free ranging wild boars hunted in Lithuania during the winter season. A total number of 27 and 25 fatty acids were identified in the intramuscular fat and subcutaneous tissue of wild boars, respectively. The weight of the wild boar had mainly affected only the levels of separate fatty acids both in the intramuscular and subcutaneous fat. Higher levels of saturated fatty acids (SFA) were found in the intramuscular and subcutaneous fat of males compared with females. The effect of both weight and sex on the levels of fatty acids was higher in the subcutaneous fat than in the intramuscular fat. Weight, sex and hunting month had no effect on PUFA/SFA and n-6 PUFA/n-3 PUFA ratios in the intramuscular and subcutaneous fat. The atherogenic (AI) and thrombogenic (TI) indexes and hypocholesterolemic/hypercholesterolemic ratio in subcutaneous fat were more favorable in females compared with males and in the January hunting season than in November and December

Fatty acid and microbiological profile of the meat (longissimus dorsi muscle) of wild boar (Sus scropha scropha) hunted in Tuscany

“…As regards the meat quality indices, few statistical differences were found, reflecting the results for single fatty acids, and in agreement with the findings of other authors (Quaresma et al 2011, Razmaite et al 2012Sales & Kotrba 2013). Gender did not influence any ratio, thus it is possible to affirm that meat from males and females has a similar quality.…”

“…C22:2 n-6 (p ¼ .01) was higher in November than in the other months, with a generally higher average value than the findings of Sales and Kotrba (2013). Therefore, higher levels of monounsaturated fatty acids, were found in meat from animals hunted in December and January vs October and November (p ¼ .02), in disagreement with Razmaite et al (2012) who reported similar values in all hunting period; December and January values were similar to those of Sales and Kotrba (2013). The polyunsaturated fatty acids, however, were lower in December and January than October and November (p ¼ .01) again in disagreement with Razmaite et al (2012) who showed lower PUFA levels without any differences in all hunting periods.…”

“…There were also statistical differences (p ¼ .02) for palmitic acid (C16:0), with a similar average value to the findings of Razmaite et al (2012). A higher value of C16:1 n-7 (p ¼ .01) was found in December than in other months in disagreement with Razmaite et al (2012) who reported values that were similar throughout the winter season. C18:1 (p ¼ .01) was higher in December and January compared with October and November.…”

“…This value is lower than the findings of Quaresma et al (2011) on psoas major muscle, who reported that gender had no influence on this fatty acid (2.2% and 2.3% for females and males respectively); Razmaite et al (2012) recorded a higher level for this acid, 3.01% in females and 3.31% in males.…”

“…Conversely, total C18:2 was higher in October and November than in December and January (p ¼ .01). C20:1 had a higher value in November than in other months with higher values in comparison to Razmaite et al (2012) who found similar values in all the hunting months. C22:2 n-6 (p ¼ .01) was higher in November than in the other months, with a generally higher average value than the findings of Sales and Kotrba (2013).…”
