Sažetak
Aiming determination of the differences in prevalence of subclinical ketosis and subsequent daily milk yield due to dairy cattle breed more than 4.6 million of test-day records collected in regular milk recording of dairy cattle in Croatia were used. The subclinical ketosis prevalence was indicated by the fat to protein (F/P) ratio, while subclinical ketosis was indicated by the F/P ratio and cows daily production. The effect of subclinical disorders on daily milk traits were tested by Scheffe’s method (SAS/ STAT). The highest subclinical ketosis prevalence occurred in early lactation (until 15th day of lactation in Holsteins and 25th day in Simmentals) with highest prevalence in first parity cows. Regarding the parity, in both breeds, highest prevalence in the beginning of lactation, occurred in cows in first, then in third parity, with the lowest prevalence in second lactation. Regarding the breed, Holsteins experienced higher subclinical ketosis prevalence compared to Simmentals in all lactation stages and all parities. Furthermore, a significant negative effect of subclinical ketosis on daily milk yield in each parity and both breeds was determined in both subsequent milk controls (A-1, A-2). Finally, it should be emphasized that test-day records could be used as cost effective and non- invasive method for monitoring the herd health enabling farmer early reaction and prevention of development of strong clinical symptoms.
