Description
| - Aim was to do a reciprocal validation of reliability of milk indicators (fat/crude protein F/CP and fat/lactose F/L) for subclinical ketosis (SK) identification. There were: dairy cows on 1st and other lactations free of clinical and superior subclinical mastitis; 3 herds of Czech Fleckvieh (CF) breed, 3 herds of Holstein (H) breed and 1 herd with CF and H; 329 individual milk samples from summer and winter season and 1st third of lactation. Average milk yield varied from 5,500 to 10,000 kg per lactation. Thresholds of F/CP and F/L were estimated (P < 0.05) according to SK milk acetone cut–off limit (> 10 mg.l–1). These were: for first lactation 1.27 (CF) and 1.32 (H), for other lactations 1.52 (CF) and 1.42 (H) in F/CP; for first lactation 0.84 (CF) and 0.84 (H), for other lactations 0.87 (CF) and 0.85 (H) in F/L. They were used for cross validation (P < 0.001) in the same order: 1.251, 1.31, 1.31 and 1.383 in F/CP; 0.831, 0.821, 0.989 and 0.852 in F/L. Validated cut–off limits are quite similar to their original values. It confirmes good reliability of original limits. These can be used in animal husbandry. Use of both quotients could improve the investigation of SK in practice.
