Sažetak
The objective of this study was to verify the presence of oxidative enzymes in the quadriceps femoris muscle of Lika Pramenka sheep and to evaluate the effect of supplement from button mushrooms, Agaricus bisporus (A. bisporus), on the histochemical and morphological characteristics of the muscles. Fourteen oneyear-old Lika Pramenka sheep were randomly divided into two groups (control and experimental groups) comprising 7 animals each. The experiment was conducted over a period of 6 weeks of the winter feeding period. The control group of sheep was fed with a standard feed without antimicrobials or growth promoters. The experimental group was given the same feed but with an additional 1.5% of dry A. bisporus. During the experiment access to water and feed was ad libitum. Samples were tested for the size and type of muscle fibers, as well as for the presence of oxidative enzymes. The diameter of muscle fibers and histochemical reactions profiles were significantly greater in animals fed with the A. bisporus supplement. On the basis of the increased activity of oxidative enzymes, which resulted in pronounced cell metabolism and increased muscle mass, we conclude that A. bisporus displays growth promoter effects.
