Milk fat free fatty acids in dependence on health of dairy cows

Popis výsledku v původním jazyce

Free fatty acids (FFAs) in fat are important indicator of raw milk quality. The aim was to analyse the relationships and quantify effects of dairy cow mastitis on FFAs. Individual milk samples (IMSs; n 307) came form Holstein and Czech Fleckvieh cows (67 : 33%). IMSs were classified into 3 groups according to somatic cell count (SCC): A LESS-THAN OR EQUAL TO 150, healthy; B from 800 to 1 500, subclinical mastitis; C > 1 500 10^3.ml-1, subclinical and clinical mastitis. With growing intensity of secretion disorder the content of FFAs increased from 0.65 +- 0.209 (A) to 1.44 +- 0.379 mmol.100g-1 (C; P < 0.001). The mastitis state (SCC) deteriorated milk quality by increase of FFAs, 0.703 (P < 0.001; by 121.5%) and reduced L, -0.522 (P < 0.001). Increased SCC by 1000 10^3.ml-1 increased FFAs by 0.433 mmol.100g-1. A risk increase of ketosis coefficients (F/P and F/L) deteriorated milk quality by increase of FFAs, 0.395 and 0.443 (P < 0.001) where 0.1 is equal to 0.05 and 0.067 mmol.100g-1.
