“…By contrast, the beef from the oat treatments was higher in C18:3 n-6 fatty acid content than that from the P-treatment (P≤0.05), whereas the beef from the LO and SW treatments had higher contents of C20:3 n-6 than the beef from the Ptreatment (P≤0.05). The percentages of all PUFAs were similar to those reported in other studies that used different sources of feed (Garcia et al, 2008;Morales et al, 2012).…”

“…The concentration of conjugated linoleic acid c-9 t-11 in adipose tissue is higher when animals are fed on pasture than when fed on stored forage or grain (Schor et al, 2008). Other studies also showed that steers finished on pasture had higher beef contents of CLA c-9 t-11 than those finished on grain-based diets (Realini et al, 2004;Garcia et al, 2008;Leheska et al, 2008;.…”

The physicochemical and sensory attributes and the fatty acid composition of the longissimus lumborum muscle were determined. The beef from pasture-fed animals tended to be tenderer, darker, less red, and with yellower fat than the beef from grain-fed steers. The beef from steers fed wheat plus silage for 75 d had lower tenderness scores than beef from steers fed for 35 d on grain plus silage. The beef from pasture-fed steers had higher levels of conjugated linoleic acid c-9 t-11 and n-3 fatty acids and a lower n-6:n-3 fatty acid ratio than the beef from grain-fed steers. The time fed on grain plus silage had a significant effect on the fatty acid composition of the beef from steers fed wheat, but no similar effect was observed in beef from steers fed oats. However, the n-6:n-3 ratio of beef was more favorable when steers were fed grain (wheat or oats) plus silage for 35 d than for 75 d.

“…In this study, as in a previous one, we found some evidence of genetic variation in LA and ALA proportions in beef lipids (Garcia et al 2008). Nuernberg et al (2005) found that the percentages of ALA in German Simmental and German Holstein bulls fed with grass or concentrate increased whereas the percentage of LA were only affected by breed being higher in German Simmental intramuscular fat.…”

“…Steers finished on a grain diet show a 2.5 times higher n-6/n-3 PUFAs ratio than those finished on pasture (Basarab et al, 2007;Duckett et al, 2009). However, the fold of increase in the n-6/n-3 FA ratio can be higher when examined in beef muscles (Garcia et al, 2008). Similar results have been found for others with crossbreed heifers offered a control diet of grass silage and concentrate (Sarries et al, 2009).…”

“…The impact of finishing system and breed on FA profiles of cattle meat has been investigated by various authors (French et al 2000;Garcia et al 2008;Gatellier et al 2005;Rossato et al 2010), and there are indications that important interactions exist between the two factors (Nuernberg et al 2005), such that B. indicus cattle tend to accumulate higher amounts of SFA than B. taurus, especially when they are finished intensively (Bressan et al 2011). On the other hand, heterosis for FA profiles has been shown to exist in crosses between B. taurus and B. indicus, but it also depends on the finishing system considered (Gama et al 2013).…”

Bos indicus (n ¼ 67) and crossbred Bos taurus Â Bos indicus (n ¼ 67) bulls were finished in extensive or intensive conditions to evaluate the effect of genetic differences and finishing system on the fatty acid (FA) composition of intramuscular fat. Finishing system had a more pronounced effect on FA profiles than the genetic group, but the two factors often interacted for both individual and groups of FA. When compared with animals finished intensively, those finished on pasture produced meat with higher concentration of CLA and polyunsaturated n-3 FA, in particular of 18:3, 20:5 and 22:5. Meat from animals finished intensively had higher amounts of 14:0, 16:0, 18:1 trans-10, 18:1 trans-11, monounsaturated trans FA and 18:2. When the two genetic groups were compared under intensive finishing, B. indicus animals showed lower amounts of 20:4 (synthesised from 18:2) and 20:5 (synthesised from 18:3), suggesting that they may have a lower ability in biochemical pathways involved in the metabolism of n-6 and n-3 long chain fatty acids. Overall, meat from animals finished on pasture had a higher amount of the FA considered desirable for human health. ARTICLE HISTORY
