Colostrum is a substance, very often called „the first milk“, since in it produced 72 hours after delivery. The consumption of colostrum has increased recently due to its health beneficial composition. The health beneficial properties of colostrum are mainly connected with the content of bioactive colostrum proteins (IgG1, IgG2, IgM, IgA). These biologically active substances … [Read more…]
The aim of this study was to monitor physicochemical changes in the meat (thigh, back and shoulder) of hunted free-living rabbits and farmed rabbits during the process of post mortem aging. We monitored the concentration of lactic acid, the pH value and the amount of malondialdehyde as a secondary product of fat decomposition changes. The … [Read more…]
The basic characteristics of meat include its colour, water holding capacity and tenderness. These properties are influenced by the chemical composition of the meat (muscle), the proportions of different types of muscle fibres, the physical and chemical condition of the muscle, and the integrity of the internal structures of muscle fibres. The most important variables … [Read more…]
The aim of this study was to compare meat yield and physical meat properties in two genotypes of goose, i.e. the Czech goose (CG) and the Novohradská goose (NG), in dependence on sex. Slaughter analysis and evaluation of meat quality were conducted at the age of 56 days in 32 goslings (8 of each genotype … [Read more…]
The intent of this study was to evaluate the effect of a commercial type of cattle on the parameters of quality in the beef carcass and its meat (dry matter, content of protein, fat and ash). The values in the CIELab system were also monitored. In total, 87 bulls were involved in the experiment (35 … [Read more…]
During the performance of microbiological analyses, important groups of microorganisms whose action may have a significant influence on the quality of chilled beef meat stored aerobically and vacuum-packed were monitored in samples of beef on days 1, 3, 7 and 14. Samples of beef rump (musculus semimembranosus) and sirloin (musculus longissimus thoracis et lumborum) from … [Read more…]
