Analyzed was the meat quality of fatteners, which were reared indoor or outdoor, in bedded or nonbedded pens, and fed a complete feed mixture or a complete feed mixture and, additionally, a green forage of alfalfa. The crossbred fatteners [♀(♀ PL × ♂ PLW) × ♂ (♀ Pietrain × ♂ Duroc)] were divided into six experimental groups, 15 pigs in each group. Samples of m. Longissimus dorsi were collected from the fattener carcasses and in the samples determined were the basic chemical composition, physicochemical and sensory properties, and fatty acid profile. The lowest level of crude fat was found in the meat samples derived from the fatteners reared indoor in bedded pens and fed a fodder with green forage of alfalfa added. The highest level of monounsaturated fatty acids (MUFA) was obtained in the meat samples derived from the fatteners kept outdoor, without bedding, regardless of the feeding type applied. The meat derived from the fatteners kept in bedded pens, fed a complete feed mixture and, additionally, green forage of alfalfa was characterized by the least desirable aroma and the best juiciness. Under the particular conditions of the experiment accomplished, it was impossible to clearly and precisely determine what methods of feeding and rearing the fatteners impacted the significant improvement of the quality of meat thereof.
