“…Saturated fatty acids 16:0 and 18:0, monounsaturated fatty acid 9c18:1 and polyunsaturated fatty acid 6c18:2 were the most abundant fatty acids in the intramuscular fat and this concurs with results reported for meat from young bulls of different origins (i.e. Belgian Blue, Limousin, Irish, Argentine and Pirenaica) raised in traditional production systems (Raes et al, 2003;Albertí et al, 2014). In fact, 9c18:1 and 16:0 fatty acids were the commonest fatty acids in the intramuscular fat of the young bulls (around 30 and 25% of the total of fatty acid detected, respectively), as was described by other authors in beef (Alfaia et al, 2009;Martínez et al, 2013).…”

Fatty acid profile as a tool to trace the origin of beef in pasture- and grain-fed young bulls of Retinta breed

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.

“…These values suggest that there was no increased stress before slaughter, because the acidification of the muscle occurred as expected. Similar values of lightness, chroma and hue angle were reported by Albertí et al (2014) in young bulls of the Pirenaica breed fed a concentrate diet, and the chemical composition of LT muscle was close to the values reported by Moloney et al (2008) when Charolais × Friesian steers were fed a 60:40 concentrate to forage diet. The WBSF values recorded in LT muscle in both treatments (41.8 N, on average) were below the threshold of 58.9 N proposed by Shackelford et al (1997) to differentiate between tender and tough meat.…”

Performance, behaviour and meat quality of beef heifers fed concentrate and straw offered as total mixed ration or free-choice

et al. 2015

Eighteen Simmental heifers were fed concentrate and barley straw offered as a total mixed ration (TMR) or separately as a free choice (FCH) to compare performance, behaviour, and meat quality. The heifers were assigned to treatments in a randomized complete block design. Animals were allotted to roofed pens with 3 animals per pen, and 3 pens per treatment. Intake of concentrate, average daily gain, and gain to feed ratio were not different between diets, being on average 7.6 kg/day, 1.38 kg/day and 0.18 kg/kg, respectively. Straw intake was greater in TMR than in FCH treatment (0.7 vs 0.3 kg/day, respectively; p<0.001). Crude protein intake, neutral detergent fibre intake and water consumption did not differ between treatments. Time spent eating was longer in FCH than in TMR (p=0.001), whereas time spent ruminating and total chewing time were longer (p<0.01) in TMR than in FCH. The number of displacements resulting from competition for feed in the main feeder in TMR treatment tended to be greater than in FCH treatment. There were no differences in the carcass characteristics and quality of meat of animals assigned to the different feeding methods, but the percentage of 18:2 n-6 was higher in FCH treatment. In summary, these results suggest that the use of TMR as a feeding method in beef cattle fed high concentrate diets did not affect performance and increased time spent ruminating with a potential decrease of ruminal acidosis incidence.Additional key words: beef cattle; feeding method; high concentrate diets.

“…Gomez et al (2014) analyzed the intramuscular fat in the same animals as the current study (Table 1). The inclusion of linseed in the diet increased the amount of n-3 PUFA in the intramuscular fat by 3.7 fold (P ⩽ 0.001), greater than the two-fold increase when linseed was added at 5% in the diet (Albertí et al, 2014). Some authors have reported that CLA supplementation in pig diets reduces backfat and increases marbling (Barnes et al, 2012).…”

Instrumental assessments and sensory tests were performed to evaluate the effects of diet and postmortem ageing time (1, 7 and 21 days) on beef quality. A total of 48 Friesian calves were randomly allocated to four dietary treatments: control, whole linseed (10% linseed), conjugated linoleic acid (CLA) (2% protected CLA), and whole linseed + CLA (10% linseed and 2% protected CLA). Animals were slaughtered at 458 ± 16.6 kg live weight and 11 months of age. Ageing was more significant than diet on most instrumental parameters. Meat from linseed enriched diets had greater drip loss ( P ⩽ 0.001) and intramuscular fat ( P ⩽ 0.01) than meat from animals fed CLA. Beef aged for 7 and 21 days had lower cooking losses ( P ⩽ 0.01) and shear force ( P ⩽ 0.001) than beef aged for 1 day. Lightness was affected only by display time. The addition of CLA in the diet increased hue and yellowness, whereas the inclusion of linseed decreased these values, as well as increased redness. Linseed in the diet decreased fat odour ( P ⩽ 0.05), but increased beef ( P ⩽ 0.01) and liver ( P ⩽ 0.05) flavours. Meat aged for 21 days was significantly more rancid ( P ⩽ 0.001), even under vacuum storage. Several organoleptic properties were improved with the inclusion of linseed in the diet, whereas they remained unaffected by the inclusion of CLA.
