Abstract. The aim of this research was to determine differences in beef carcass fatness and in the fatty acid composition of muscle and adipose tissue of three different breeds slaughtered at the age of 14 months and 19 months. The breed significantly affected the muscle fat content, carcass subcutaneous fat tissue thickness and fatty acid composition of the muscle and subcutaneous fat tissue. Different age at slaughter had no significant effect on analysed traits. The muscle tissue of the Herefords contained a higher (P < 0.05) percentage of C14 : 0 and C16 : 0 fatty acids and fewer long-chain fatty acids than the Simmentals and Charolais. The subcutaneous fat tissue of the Simmentals contained a higher (P < 0.05) percentage of PUFA, PUFA/SFA ratio and n-6 fatty acids. When fed with a high-energy diet, the Herefords proved to have the most fattened carcasses and the highest content of saturated fatty acids in the muscle. Changes in the diet of feedlot cattle should result in a more favourable fatty acid composition.

In this study, the effect of soybean meal substitution by raw chickpea seeds on the thermal properties and fatty acid profile of subcutaneous fat tissue of broiler chickens was examined. The experiment, performed on Ross 308 chickens, lasted for 42 days. Tight subcutaneous fat tissue was analyzed using differential scanning calorimetry (DSC) measurements while the fatty acid composition of subcutaneous adipose tissue was determined chromatographically. There was no effect of soybean meal substitution on fat crystallization temperature or crystallization enthalpy. However, the total calorimetric enthalpy of the melting of low-melting monounsaturated and saturated triacylglycerols differed between groups. Fatty acid proportions in the subcutaneous fat tissue of broiler chickens were also altered. Among others, chickpea seed inclusion decreased the content of main saturated acid (palmitic acid) and increased the content of main monounsaturated (oleic) and tri-unsaturated (linolenic) acids. The results show that the soybean meal substitution by raw chickpea seeds in the feed can affect the structural properties of adipose tissue in broiler chickens, including the thermal transformation of unsaturated fatty acids. Due to the numerous physiological functions of subcutaneous fat tissue, understanding these mechanisms can promote the use of alternative protein both in poultry and human nutrition.
