METHOD OF ASSESSMENT OF LEVEL OF MORPHOFUNCTIONAL DEVELOPMENT OF NEWBORN CALVES Russian patent published in 2014 - IPC G01N33/48 A01K67/02 

FIELD: veterinary medicine.

SUBSTANCE: at the age of 1-3 days in the blood of calves the content of foetal haemoglobin, calcium and magnesium is determined. The ratio of calcium and magnesium is calculated. The clinically healthy state and the normal level of development of newborn calves is proved by the level of ratio of calcium/magnesium which is greater or equal to 2.9 and the content of foetal haemoglobin is greater than 60% of the total haemoglobin. The morphofunctional immaturity is proved by the level of the ratio of calcium/magnesium which is less than 2.9 and the content of foetal haemoglobin is less or equal to 60%. Informativeness of the proposed indicators is maintained up to 3 days age, but it is recommended to carry out the assessment of the level of development of calves at the age of 1 day, which enables to carry out more quickly the necessary measures aimed at correcting their physiological state and the prevention of possible diseases. The method enables to assess the muscle metabolism on the ratio of calcium and magnesium, and the usefulness of development of the mechanisms of the haemoglobin synthesis on the level of foetal haemoglobin, changes that occur in the majority of cases of disturbance of prenatal development and/or during birth.

EFFECT: increase in informativeness and the predictive value of the method.
