The predicative value and correlations of two milk indicators in monitoring energy metabolism of two breeds of dairy cows

Original language description

Milk acetone (AC) in combination with fat/crude protein (F/CP) ratio represents good ketosis indicators. 960 individual milk samples (MSs) from the Holstein (H) and Czech Fleckvieh (C) dairy cows (1 : 1). AC levels differed P > 0.05 between H and C in whole lactation and significantly (P < 0.05) in the 1st third of lactation (FTL; 2.20 > 1.72 mg.l-1). F/CP did not differ between breeds. AC and F/CP are good indicators for prevention of subclinical ketosis in dairy cows because of good correlations between them (0.23, 0.28 was found in H cows in FTL in summer (0.48, P < 0.001). Discrimination limits for H, 0.19 C; P < 0.001), especially in FTL (0.33 (n = 329), 0.36 H, 0.30 C; P < 0.001). Indicators correlated more in summer than in winter season (0.38 >0.29, P < 0.001, in FTL). The closest relationship was found in H cows in FTL in summer (0.48, P < 0.001). Discrimination limits for subclinical ketosis for F/CP (relevant AC threshold 10 mg.l-1) could be 1.32 and 1.42 (H) and 1.27 and 1
