Název v původním jazyce

Growth, carcass traits, chemical composition and fatty acid profile in beef from Charolais and Simmental bulls fed different types of dietary lipids

Popis výsledku v původním jazyce

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 edibletissues. 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.
