Abstract: O objetivo neste experimento foi avaliar os efeitos do genótipo sobre a composição química e o perfil de ácidos graxos no músculo longissimus dorsi de borregas. Foram utilizados 36 animais dos grupos genéticos: Santa Inês (SI), Ile de France (IF), Ile de France × Santa Inês (IF × SI), Dorper × Santa Inês (DO × SI), Texel × Santa Inês (TE × SI) e Suffolk × Santa Inês (SU × SI). Os animais foram distribuídos em blocos completos casualizados, definidos de acordo com o peso e a idade inicial. Não houve efeito do g… Show more

“…In sheep, smaller amounts of acetate reduce the deposition of palmitic acid (Church, 1993). The increase in stearic acid concentrations (Table 4) does not have negative consequences; because it does not possess unsaturations in its chain, C18:0 is considered neutral (Maia et al, 2012) and does not have a hypercholesterolemic effect (Santos Filho et al, 2001). Although an effect of the tested diet substitution on some fatty acids was observed, there was no influence on the total saturated fatty acids, whose values were very close to the values previously reported for Santa Inês male sheep (Madruga et al, 2006;Madruga et al, 2008).…”

“…The ratio (C18:0+C18:1)/C16:0 has been reported to describe the beneficial effects of the different types of lipids (Maia et al, 2012), and should be between 2 and 3 in lamb meat (Banskalieva, Sahlu, Goetsch, 2000). Therefore, although it was not influenced by the tested substitution, the values obtained may be considered satisfactory, confirming the quality of the lipid fraction of Santa Inês sheep meat.…”

“…Myristic acid (C14:0) muscle content is essentially related to dietary composition, being mainly obtained from the diet, as previously demonstrated, so the influence of the Damara breed on this fatty acids may be explained by differences in intramuscular fat, since, as already referred above, it is a fat tailed breed . The lower value of C18:4 n ‐3 might be due to the fact that this fatty acid is being used in the metabolisation of LNA, that was significantly ( P < 0.001) higher in the Damara, along the D6‐desaturase pathway …”

“…Besides that, consumers are increasingly motivated to eat healthy meat, rich in unsaturated fatty acids, omega-3 and omega-6 fatty acids and conjugated linoleic acid (CLA) (Maia et al 2012). It is known that the meat of ruminant animals has more concentration of CLA than non-ruminant meats and, among ruminants, ovine meat has the greater quantity of CLA (Schmid et al 2006).…”
