“…However, we also found significant differences between the monitored breeds in the musculus longissimus. Jeong et al (2012) focused on the comparison of meat quality traits, free amino acids, and fatty acids in longissimus lumborum muscles from Hanwoo, Holstein, and Angus steers, fattened in Korea. The results of this study have shown that there were no dramatic differences between beef from the three breeds that were fattened for 6 months under equal conditions.…”

Vopálenský J., Suchý P., Straková E., Šimek F., Macháček M., Herzig I. (2017): Amino acid levels in muscle tissue of eight meat cattle breeds. Czech J. Anim. Sci., 62, 339-346.Ten clinically healthy bulls equal in weight were chosen from eight meat cattle breeds maintained in the same geographical conditions using the extensive grazing method. After slaughtering, muscle tissue samples were taken from the musculus longissimus and pars thoracis, and dry matter, nitrogenous substances, fat, and the levels of essential (EAAs) and non-essential (NEAAs) amino acids were determined. Significant differences were found between the monitored genotypes in the contents of dry matter, nitrogenous substances, fat, EAAs, and NEAAs (P ≤ 0.05). The highest concentrations of nitrogenous substances in muscle tissue were detected in the Limousine breed and the lowest in the Aberdeen Angus breed; the highest fat content was found in Aberdeen Angus and the lowest in Galloway. Out of the total sum of EAAs, the highest percentage in the dry matter of muscle tissue in all genotypes was found for Lys (8.8-10.4%), the lowest percentage was found for Met (2.4-2.9%). The value of Thr was approximately 4.6, Val 5.1, Ile 4.8, Leu 8.2, Phe 4.1, His 4.2, and Arg 8.0%. Significant differences (P ≤ 0.05) between the monitored breeds were found in all EAAs, except for Val and Leu. Regarding NEAAs, out of the total protein, the highest percentage was found for Glu (13.9-15.1%). Conversely, the lowest values were detected for Ser (3.8-4.1%) and Tyr (3.8-4.4%). The values of other NEAAs were approximately 9.3 for Asp, 4.0 for Ser, 5.3 for Pro, 5.5 for Gly, and 6.1% for Ala. Significant differences (P ≤ 0.05) were found between the monitored genotypes in all NEAAs except for Pro and Ala. In the dry matter of muscle tissue, out of the total protein, the sum of EAAs ranged from 50.6 (Meat Simmental) to 52.0% (Limousine), and NEAAs ranged from 48.0 (Limousine) to 49.4% (Meat Simmental). Apart from its effect on the biological value of meat, representation of individual amino acids is important to enhance its taste or smell.Keywords: meat cattle breeds; musculus longissimus dorsi; dry matter; protein; fat; essential and non-essential amino acids List of abbreviations: EAAs = essential amino acids, NEAAs = non-essential amino acids, Asp = aspartic acid, Thr = threonine, Ser = serine, Glu = glutamic acid, Pro = proline, Gly = glycine, Ala = alanine, Val = valine, Met = methionine, Ile = isoleucine, Leu = leucine, Tyr = tyrosine, Phe = phenylalanine, His = histidine, Lys = lysine, Arg = arginine, AA = Aberdeen Angus, BA = Blonde d'Aquitaine, Lim = Limousine, Char = Charolais, Gas = Gasconne, MS = Meat Simmental, Sal = Salers, Gall = Galloway

“…Considering the daily feed cost, feeding TMR in order to achieve Korean beef carcass standard (highly marbled beef) was not efficient in current study. Jeong et al (2012) found no differences in meat quality between Korean native cattle (Hanwoo) and Holstein steers that were finished under similar conditions on a high-energy diet for 6 months. However, the nutrient composition and daily intake of the conventional diet (TMR) used in this study differed from those of the diets that are commonly used for Hanwoo fattening programs in Korea (Panjono et al, 2009).…”

Holstein-Friesian steer beef production is renowned globally as a secondary product of the milk industry. Grass feeding is a common practice in raising Holstein steers because of its low cost. Furthermore, grass feeding is an alternative way to produce beef with a balanced n-6 to n-3 fatty acids (FAs) ratio. However, the performance and meat quality of Holstein-Friesian cattle is more likely to depend on a high-quality diet. The aim of this study was to observe whether feeding two mixed diets; a corn-based total mixed ration (TMR) with winter ryegrass (Lolium perenne) or flaxseed oil-supplemented pellets with reed canary grass haylage (n-3 mix) provided benefits on carcass weight, meat quality and FA composition compared with cattle fed with reed canary grass (Phalaris arundinacea) haylage alone. In all, 15 21-month-old Holstein-Friesian steers were randomly assigned to three group pens, were allowed free access to water and were fed different experimental diets for 150 days. Blood samples were taken a week before slaughter. Carcass weight and meat quality were evaluated after slaughter. Plasma lipid levels and aspartate aminotransferase (AST), γ-glutamyl transpeptidase (GGT), creatine kinase (CK) and alkaline phosphatase (ALP) activities were determined. Diet did not affect plasma triglyceride levels and GGT activity. Plasma cholesterol levels, including low-density and high-density lipoproteins, were higher in both mixed-diet groups than in the haylae group. The highest activities of plasma AST, CK and ALP were observed in the haylage group, followed by n-3 mix and TMR groups, respectively. Carcass weight was lower in the haylage group than in the other groups and no differences were found between the TMR and n-3 mix groups. Although the n-3 mix-fed and haylage-fed beef provided lower n-6 to n-3 FAs ratio than TMR-fed beef, the roasted beef obtained from the TMR group was more acceptable with better overall meat physicochemical properties and sensory scores. According to daily cost, carcass weight and n-6 to n-3 FAs ratio, the finishing diet containing flaxseed oil-supplemented pellets and reed canary grass haylage at the as-fed ratio of 40 : 60 could be beneficial for the production of n-3-enriched beef.

“…Cho et al [24] also reported lower C18:2 and PUFA percentages for the longissimus muscle fat of KC versus AN. In addition, Jeong et al [31] reported that the longissimus lumborum of KC had lower C18:2 and PUFA percentages than that of HO. Hwang and Joo [8] reported that C18:1n9 was positively associated with beef flavor, whereas PUFAs were negatively associated with beef flavor.…”
