Relationships of fatty acid group contents in milk and reproductive performance in Holstein cows

Popis výsledku v původním jazyce

The aim of this study was to evaluate the relationships between milk fatty acid group contents and subsequent reproductive performance in Holstein cows. A total of 27 cows in 1st to 4th lactation were included in the evaluation. These cows were divided to primiparous and multiparous groups within the statistic evaluation. The data were processed and evaluated with Microsoft Office Excel and the statistical software SAS 9.3. Daily milk yields increased in the first eight weeks of lactation. Body condition score decreased until the third month of lactation. As the cows gradually recovered from the negative energy balance, the contents of saturated fatty acids (SFA) increased, whereas the contents of monounsaturated (MUFA) and polyunsaturated (PUFA) fattyacids decreased. The contents of SFA and MUFA were significantly (P < 0.01 ? 0.05) correlated (r = -0.279 to r = 0.275) with all the reproductive traits evaluated (calving to first insemination interval, days open and insemination index)
