Abstract/OtherAbstract:
|
The effects of sex, slaughtered age (9 vs. 12 months) and livestock production system (freedom extensive system vs. semi extensive system) of "Galician Mountain" foals breed on the fatty acid composition were studied. The sex and slaughtered age of the animals had no statistical significance in the intramuscular fatty acids. Furthermore, the livestock production system showed differences in the fatty acid profiles from the Longissimus dorsi. The feeding system showed significant differences in PUFA content (P<0.001) higher in freedom extensive production system that semi extensive system, whereas MUFA content was significantly (P<0.001) higher in semi extensive system. This major PUFA content in freedom extensive production showed a significant (r=0.70, P<0.01) correlation with C18:3n-3 content and can be attributed to their eaten only pasture until slaughtered. The higher MUFA contents (P<0.001) observed for semi extensive production system foals were very significant (r=0.98, p<0.01) correlated with C18:1cis-9 content and less significant (r=0.81, P<0.01) correlated with C16:1cis-9 content. In addition, the data reinforced the evidence that foals from extensive production system on wood pasture have a higher nutritional quality (mainly due to the higher levels of n-3 PUFA) when compared to concentrate-fed foals, as a result of the beneficial effects of grass on meat fatty acid profiles. |
