Recently, consumers have been seeking natural and healthy products such as meat rich in polyunsaturated fatty acids, beneficial for health with decreasing the saturated fatty acids. Then, to enhance the meat quality, some nutritional strategies were considered such as using the residues of aromatic and medicinal plants. Then, the use of rosemary residues in lamb feeding increased the polyunsaturated fatty acid, n-6 and n-3 contents and reduced the saturation index in muscles and adipose tissues.

In an experiment the longissimus lumborum and gluteus medius muscles were collected from lambs of two genotypes to analyse physico-chemical traits, fatty acid profile, taurine, carnosine, and L-carnitine. Results showed a greater impact of the lamb’s genotype on physical traits of meat than on its chemical composition and content of bioactive components. Muscle type had an effect on meat colour; collagen content; fatty acid profile; and the amount of taurine, carnosine, and L-carnitine.

This study aimed to assess drip loss measurements in mutton taken by different methods (EZ and bag, BM) and their relationship with pH values and color. Mutton samples originating from 20 ewes of Istrian sheep were used to examine the effect of the method on drip loss after 24 and 48 h. EZ and BM method in mutton do not provide equivalent results for measuring drip loss. Comparisons of the results obtained with different methods should be avoided or at least performed with great precaution.

The aim of this study was to compare the chemical composition and fatty acid content of the muscle tissues of lambs and adult sheep. The results support the inclusion of dietitian-recommended mutton into the human diet and the promotion of the production of meat from adult animals as a high-value product. The sheep industry could benefit economically, particularly in countries where this meat type has not enjoyed a high standing in consumer preferences.

The research was carried out on lamb meat to determine the physicochemical characteristics and oxidative stability of lipids. The analysis was performed on fresh and 14 d aged longissimus lumborum and gluteus medius muscles. The meat aging determined all physicochemical features except protein and fat content. The tenderness of meat was better in muscles aged for 14 d. The muscles differed in the degree of lipid peroxidation in both fresh and aged meat.
