The effect of parity on the proportion of important healthy fatty acids in raw milk of Holstein cows

Popis výsledku v původním jazyce

The objective of study was to determine and evaluate effect of parity on the fatty acids groups proportion, with an emphasis on its potential importance for consumer health, in the Holstein cows milk during the first phase of lactations. A total of 25 Holstein cows, 9 primiparous, 9 in the 2nd, and 7 in the 3rd and subsequent parity, were observed and sampled at 7-day periods through first 17 lactation weeks. The % proportion of saturated (hypercholesterolemic and volatile as its part) and unsaturated (monounsaturated and polyunsaturated as its part) fatty acids in the samples of milk fat (n=425) was detected. The effects of parity, negative energy balance as well as regression on lactation week and fat to protein ratio were evaluated using SAS 9.3. Significantly (P < 0.01) lower proportion of unhealthy hypercholesterolemic fatty acids was detected in primiparous (-2.67%) and cows in the 3rd and subsequent lactation (-2.94%) compared to the 2nd lactation as well as simultaneously highe
