Description
  • At present, owing to understanding of the role of dietary fat in human health, the nutritional quality of meat is of great attention. Thus, recent research has focused on feeding strategies increasing unsaturated fatty acids (FA) in the lipids of edible tissues. The objective of the study was to determine the effects of breed and whole sunflower seed on growth, carcass traits, chemical composition of meat and meat FA profile in Charolais (CH) and Simmental (S) bulls. The CH bulls had a lower feed intake, a higher killing out percentage and carcasses that are more valuable. The superiority of the CH over the S breed in a number of economically important traits was thus demonstrated. The sunflower seed supplement increased the proportions of linoleic acid and conjugated linoleic acid and the ratio of polyunsaturated FA to saturated FA and decreased the index of atherogenicity of FA in meat lipids. The breed effect on the nutritional quality of meat was ambiguous.

  • V současné době je vzhledem k poznání účinku tuku v potravě na zdraví lidí věnována velká pozornost nutriční kvalitě masa. Současný výzkum je proto zaměřen na strategie krmení, které zvyšují obsah nenasycených mastných kyselin (MK) v tucích poživatelných tkání. Cílem práce bylo zjistit vliv plemene a slunečnicového semene v krmné dávce na růst, jatečné vlastnosti, chemické složení masa a profil MK v mase u býků plemene charolais (CH) a masný simentál (S). Býci CH přijímali méně krmiva, měli vyšší jatečnou výtěžnost a vyšší jatečnou hodnotu. Je tedy patrná převaha býků plemene CH nad S v řadě ekonomicky významných vlastností. Přídavek slunečnicového semene zvyšoval podíl kyseliny linolové a konjugované kyseliny linolové a podíl polynenasycených MK k nasyceným MK a snižoval atherogenní index MK v tucích masa. Vliv plemene na nutriční kvalitu masa se nepotvrdil. (cs)
