According to the official veterinary reports cattle in the Nizhny Novgorod region in 2014-2016 showed a decreased level of carotene in 50.2.57.9%, a total serum protein - in 20.0.24.5%, total calcium - in 33.0.35.7%, inorganic phosphorus - in 29.0.32.5%, alkaline reserve - in 12.0.13.8% of the samples studied; in the structure of non-contagious pathology, the leading place was occupied by diseases of the reproductive organs, registered in 34.0% of diseased сattle. Our own studies revealed a decreased level of inorganic phosphorus and phagocytic activity of neutrophils in dry cows in a base economy. We developed a method for optimizing the reproductive function of cows comprising daily peroral application of remedy Bio-PHAYAL at a dose of 15.20 mg/kg body weight for 5 days starting at onset of the lactation period and 10 days prior to calving, in combination with the two-fold subcutaneous injection of the preparation Bio-TEK at a dose of 10 ml/head 60 and 30 days prior to calving, two-fold intramuscular injection of tetrahydrovit at a dose of 10 ml/head 60 and 30 days prior to calving and a single intramuscular injection of sedimin at a dose of 10 ml/head 45 days prior to calving. The developed method contributed to the optimization of the reproductive function of postpartum cows, which was characterized by a decrease in the level of obstetric morbidity by 19.0.49.3%, less time required for the uterine involution by 2.8.6.1 days, a reduction in the infertility by 7.7.21.6 days and an increase of their fertility by 5.7.13.0% in comparison with analogues.
