“…Talpur et al (2008) in goats have previously reported differences between longissimus and ST muscles in the profile of fatty acids. Also, Barton et al (2008) noted significant differences significant in fatty acid composition between muscles.…”

“…Several authors reported that the type of muscle significantly influenced the intramuscular lipid content (Talpur et al, 2008;Marichal et al, 2003), although the sign of the differences may vary with age (Mahgoub et al, 2002) and genotype (Santos et al, 2007;Velasco et al, 2004;Barton et al, 2008). Rusman et al (2003) explained the lower fat content in biceps femoris muscle compared to LT due to its higher activity.…”

“…In addition, the intramuscular fat content may be responsible for the different fatty acid profile among genotypes. Barton et al (2008) demonstrated that lean animals have higher proportions of muscle PUFA due to the higher incidence of membrane phospholipids (high in PUFA). However, the breast lipid content, along with the PUFA proportion of MG birds, do not clearly confirm the findings of Barton et al (2008).…”

However, the breast lipid content, along with the PUFA proportion of MG birds, do not clearly confirm the findings of Barton et al (2008). Another hypothesis to explain these differences in the PUFA profile is that SG birds may have a higher D-6 desaturase activity, the enzyme involved in the conversion of LA to ARA as well as of LNA to EPA and DHA, being these long chain PUFA quite higher in their meat and absent both in feed and grass (Table 2).…”

The characteristics of meat quality, chemical and fatty acid composition, from fast-growing (FG) and medium-growing (MG) meat-type and slow-growing (SG) egg-type chickens reared under organic conditions were compared. Three-hundred and sixty 1-day-old male chicks, equally divided into three experimental groups represented by strains (FG: Cobb 700, MG: Naked neck Kabir and SG: Brown Classic Lohman) were housed into three poultry houses with outdoor pasture availability of 10 m 2 /bird located in the same Research Centre of the University of Perugia. All the birds were fed ad libitum the same diets formulated according to the European Union (EU) Regulations by using organic raw materials. Birds from the FG and MG groups were raised until 81 days, whereas birds from the SG group were raised until 96 days in order to achieve an acceptable market live weight. SG birds showed significantly ( P , 0.01) higher breast meat drip and cook losses, Allo-Kramer shear values and collagen content. In comparison with FG and SG, MG exhibited a higher breast meat pH (5.86% v. 5.79% and 5.78%, respectively; P , 0.01) and a lower lightness (54.88% v. 57.81% and 56.98%, respectively; P , 0.05). Genotype dramatically affected the lipid content as well as the fatty acid composition of both breast and thigh meat. SG exhibited the lowest content of lipid, both in breast and in thigh meat, the lowest proportions of monounsaturated fatty acids (MUFA) and the highest proportions of polyunsaturated fatty acids (PUFA). The total n-3 PUFA of SG breast meat was double that of FG meat and intermediate with respect to MG birds (8.07% v. 4.07% v. 5.14% total fatty acids; P , 0.01). The fatty acid composition of thigh meat is similar to that of breast meat, but the differences among genotypes are less pronounced. Total saturated fatty acids were not affected by the genotype. In conclusion, meat functional properties of FG and MG strains appeared much more attractive both for industry and consumer (lower drip and cook losses and higher tenderness), whereas from a nutritional point of view, meat from SG appeared healthier (less fat and higher content of n-3 PUFA) and thus might better fit with the consumer's expectations of organic products.

“…and Simmental bulls (Bartoň et al, 2008). It was suggested that the differences were due to different activity of Δ 9 -desaturase, which is the enzyme responsible for catalyzing the conversion of SFA to Δ 9 MUFA (Yang et al, 1999).…”

ABSTRACT:The effects of breed and diet containing different types of silages on meat quality parameters and fatty acid profile of m. longissimus lumborum (MLL) were evaluated in a total of 30 Czech Fleckvieh (CF), Charolais (CH) and Charolais × Czech Fleckvieh (CH × CF) bulls. The animals were fed two mixed diets: MS (based on maize silage) and LCS (based on legume-cereal mixture silage and lucerne silages) with different concentrations of dietary energy and fatty acids. The MLL from CH bulls had the lowest content of dry matter (P < 0.01), less protein (P < 0.01) and lighter meat (P < 0.01) compared to the CF. The extensive LCS diet reduced dry matter (P < 0.01) and intramuscular fat (P < 0.01) and increased the content of hydroxyproline (P < 0.05). The CH bulls exhibited higher PUFA n-3 (P < 0.05) and lower MUFA (P < 0.05) compared to the CF, with the CH × CF being intermediate. The LCS diet enhanced the proportions of PUFA (P < 0.05) and PUFA n-3 (P < 0.001) and reduced MUFA (P < 0.001). In conclusion, both breed and diet affected the meat quality and fatty acid profile of the intramuscular fat of the bulls. The replacement of maize silage with the legume-cereal mixture and lucerne silages in the diet reduced the concentration of intramuscular fat and improved its fatty acid profile from the human nutrition perspective.

Growth, carcass traits, chemical composition and fatty acid profile in beef from Charolais and Simmental bulls fed different types of dietary lipids

Abstract: BACKGROUND: The effect of breed and whole sunflower seed on performance, carcass traits and the composition of meat was evaluated in Charolais (CH) and Simmental (SI) bulls. Samples of musculus longissimus lumborum (MLL) and musculus infraspinatus (MIS) were analysed.
