The microscopic examination of lipid droplets in the muscles of chicken (hybrids of Vedetta line) was conducted. The section of superficial breast muscle (Musculus pectoralis thoracica) and thigh muscle (Musculus iliotibialis) were prepared for histochemical analysis. The microstructure analysis concerned quantity, size, and shape form of lipid droplets and their occurrence in the sarcoplasma and connective tissue. The computer analysis of microscopic images was conducted. The influence of rape oil, flaxseeds and α-tocopherol additions to the fodder of chicken on the size and manner of lipid droplets distribution in the sarcoplasma and connective tissue was stated.
