Effect of cow energy status on the Hypercholesterolaemic fatty acid proportion in raw milk

Popis výsledku v původním jazyce

We evaluated the proportion of fatty acid groups, with an emphasis on hypercholesterolaemic fatty acids, in the milk of 25 Holstein cows during the 1st period of lactation in relation to their negative energy balance (NEB). Sampling of each cow?s milk started the 7th day after calving. Milk samples (n=425) were collected at 7-day periods during the first 17 weeks of lactation. The proportion (%) of saturated (SFA), hypercholesterolemic (HCFA), volatile (VFA), unsaturated (UFA), monounsaturated (MUFA), and polyunsaturated fatty acids (PUFA) in the milk fat was determined. Body condition score and fat to protein ratio in milk were applied for precise determination of the NEB break point during the observed period. The effects of parity, NEB, regression on lactation week and fat to protein ratio were evaluated using SAS 9.3. Milk contained a lower proportion of SFA as well as equally higher UFA (?2.13%; P < 0.01) during the NEB period. Overcoming NEB caused an increase in SFA, however, an
