Muscle composition and fatty acid profile in lambs fattened in drylot or pasture



Muscle composition and fatty acid profile in lambs fattened in drylot or pasture



Meat science 51(4): 283-288



The effects of two fattening systems on muscle composition and fatty acid profile were determined in an experiment using samples of the longissimus dorsi (LD) muscle of 24 ram lambs (slaughter weight 29-31 kg). The fattening systems were: (i) drylot (a mixture of maize, soybean, wheat and minerals) and (ii) grazing (Cynodon dactylon). The lambs fattened in the drylot system presented higher fat levels (p < 0.01), but lower concentrations of moisture (p < 0.01) and cholesterol (p < 0.05). The lipid content presented a negative correlation with moisture and protein. In lambs fattened in the drylot system increasing levels of fatness of LD muscle were associated with a decrease (p < 0.05) in myristic and palmitic acids, but myristic, palmitic and linoleic acids increased (p < 0.05) as the cholesterol levels of the muscles increased.
