Sažetak
Beef intramuscular fatty acid (FA) profile was investigated on a sample of Simmental beef bulls from an intensive rearing system in Croatia. Animals were housed indoor in common pens on a concrete slatted floor (SF group, n=15) or a full floor with straw bedding (FF group, n=15). Diet in both groups was given as total mixture ration composed from maize grain and stalk silage, super-concentrate and hay (average composition per kg: 599 g of DM, 76 g of crude protein and 4.59 MJ of ME as feed). Bulls were slaughter at similar age (494±17 days) and body weight (597.5±56.4 kg) and the intramuscular fat (IMF) content (g/kg) and FA composition (g/100g of total FA) of the M. longissimus thoracis were determined. The average IMF content was 25.49±9.21 with C18:1 (36.28±3.99), C16:0 (22.61±1.81), C18:0 (17.18±1.71) and C18:2n-6 (9.15±3.08) as the most represented FAs. The average proportions of total saturated FA (SFA) and monounsaturated FA (MUFA) were 44.33±1.89 and 41.78±4.31, while the share of total polyunsaturated FA (PUFA) was 13.89±4.72, with the averages of n-6 and n-3 PUFA totals of 12.93±4.52 and 0.68±0.24, respectively. The PUFA/SFA and n-6/n-3 ratios were out of the nutritionally recommended limits ; while the proportion of beneficial conjugated linoleic acid (CLA) averaged 0.285±0.082 g/100g of FA. Floor type had no major effect on FA profile, except for slightly higher CLA and C20:1 and lower C12 and n-6/n-3 in SF group. It is concluded that the obtained results imply a need for feeding strategy that could enhance the nutritional quality of beef FA under the intensive production systems.
