“…No statistically significant correlation was found between the ∆9 desaturase index and total lipid content. These results are in agreement with the findings of Corazzin et al (2013), which showed no differences in the ∆9 desaturase index when comparing animals with different subcutaneous fat deposits, but in contrast with the findings of Jiang et al (2008), who reported a positive correlation between ∆9 desaturase activity and the marbling of beef. Level of significance:* P <0.05; ** P <0.01;***P <0.001; ns: not significant.…”

This study analysed the meat fatty acid (FA) composition of three zebu breeds, Gudali (GU), White Fulani (WF) and Red Mbororo (RM), raised on savannah pasture and monitored in the commercial context of the Yaoundé abattoir. Samples of m. longissimus thoracis from 60 bulls belonging to the GU, WF and RM breeds were collected and analysed for fat and FA composition. The fat content of the meat was low, but similar across breeds (1.34 ± 0.912 g/100 g muscle, mean ± SD). Meat from the GU breed had higher C18:3n-3 and C22:5n-3 proportions and lower C18:0 and total saturated FA proportions than WF meat. Red Mbororo meat had an intermediate FA composition compared with the other breeds. The elongase and ∆9 desaturase indices were comparable among breeds. In summary, the results indicate that there are minimal differences in beef FA composition of the three breeds from the Central African sub-region. Additionally, based on the polyunsaturated FA (PUFA) proportion, 13.9% of the total lipids and n-6/n-3 PUFA ratio, 1.95, consumption of beef from these breeds could be beneficial to human health. This is possibly owing to the pasture feeding and low fat content of the beef.

“…Also, the latter authors hypothesized that feeding FP can increase Δ9 desaturase activity. In general, previous studies reported that diet can influence the activity and expression of Δ9 desaturase . However, Δ9 desaturase is involved in the synthesis of the main conjugated linoleic acid (CLA) isomer (CLA c 9, t 11) .…”

“…SCD1 inserts the cis-9 double bond in stearic acid to make oleic acid. In fact, Hiller et al (2011) reported an increase in SCD1 gene expression in bovine muscle after feeding bulls a grain-based diet, while Dervishi et al (2011) and Corazzin et al (2013) reported that SCD gene expression could be reduced by grazing.…”

This research explores the possibility of using the fatty acid profiles of intramuscular fat to authenticate the origin of Retinta breed meat according to different feeding regimes based on the combined use of concentrate and grass or forage (GP, grass pasture; MC, medium concentrate; HC, high concentrate). Young bulls from GP (n=30) were reared on grass pasture and supplement with concentrate in controlled feeders; MC (n=30) and HC (n=15) were reared in farm buildings using 40 and 80% concentrate of total dry matter from diet, respectively. The stepclass function in R was used to perform a stepwise linear discriminant analysis including thirty fatty acids from intramuscular fat. Two fatty acids, 9c18:1 and 22:5 n-3 were selected as discriminators of the meat origin. Meat from the GP and MC was characterized by higher 22:5 n-3 (p<0.05), while HC meat showed higher 9c18:1 (p<0.05). The use of 9c18:1 and 22:5 n-3 fatty acids from intramuscular fat resulted in a correct assignation of 100% of beef samples to each of the feeding regimes. Therefore, in addition to serving as an effective tool for discriminating between feeding regimes in the origin of the beef, the fatty acid profile of intramuscular fat could help companies to check the authenticity of the meat origin.Additional keywords: pasture; concentrate supplement; discriminant analysis; gas chromatography.
