Балльная оценка упитанности, молочная продуктивность и биохимические показатели крови у высокопродуктивных коров

The aim of this work was to study the relationship of body condition evaluated in scores (BCS) on a scale of1 to 5, in the dry period with milk production, hematological and biochemical indices of blood of cows. Three groups of Russian Black and White cows of fatness in the dry period (1 st BCS 1.5 to 3.0, 2 nd BCS 4.0 to 5.0 and control, BCS 3.0 to 4.0) wdre formed and studied the dynamics of changes in BCS on the 1st, 3rd, 5th and 7th months of lactation. During the 1 st month of lactation in the 2 nd and control groups, respectively, BCS has decreased from 4.2 to 3.5 and from 3.5 to 2.8, while in the 1 st group it increased from 2.5 to 3.2. Further BCS from month to month were fallen to 2 or less. Yield for the previous 305 days of lactation in cows of the 1 st, 2 nd and control groups was equal, respectively, 6938, 7944 (p st, 2 nd and control groups was 7628, 7470 and 7500 kg of milk, the fat productions are 318, 307 and 292 kg. Days open the 1 st and 2 nd groups, respectively, equal to 125 and 154 days (p
