Changes in milk fatty acid composition in relation to indicators of energy balance in holstein cows

Original language description

The contents of protein (P), fat (F), a F:P ratio, and content of individual fatty acids (FA) and groups of FA, including ratio of SFA:UFA (saturated FA-to-unsaturated FA) and MUFA:PUFA (ratio monounsaturated FA-to-polyunsaturated FA) in milk during thefirst 17 weeks of lactation with respect to the development of NEB demonstrated by the change in cows? body condition. The resulting changes of the fat-to-protein ratio over time are associated with adipose tissue mobilization due to NEB. The highest concentrations of saturated FA (SFA) were observed for C14:0, C16:0, C18:0, and also for the SFA with low carbon numbers. The highest concentrations of unsaturated FA (UFA) were determined for C18:1, C18:2, and C16:1. The changes in MUFA:PUFA in milk duringthe first 5 weeks of lactation differed between the cows with low and high decrease of BCS one month after calving. The results suggest the possibility of using MUFA:PUFA ratios as suitable indicators of NEB in cows after calving.
