Nutritionally desirable fatty acids including CLA of cow´s milk fat explained by animal and feed factors

Popis výsledku v původním jazyce

This study evaluated the effects of four factors (breed, parity, month of lactation and feeding ration) on the total explained variation (R^2) determining composition of nutritionally important fatty acids. Individual milk samples were collected four times over an entire year (March, June, September, and December, respectively) on a conventional farm from two breeds: Czech Fleckvieh (dual-purpose, local) and Holstein (dairy, worldwide). In total, 145 samples (36; 38; 35 and 36, respectively) were analysed. Within the R^2, feeding ration and month of lactation were the main factors affecting milk fatty acids composition, whereas breed and parity showed a low effect. A high percentage of the R^2 was observed in rumenic acid (52%), for example, whereas a low percentage was observed in both palmitic acid (30%) and oleic acid (30%). This may be due to intra-breed variability affected by different genetic predisposition of each cows, their performance or individual response to changes in feeding ration.
