Abstract

FIELD: veterinary.

SUBSTANCE: invention relates to veterinary medicine and is intended for predicting postpartum complications in cows of black and motley breed. Compare the morphological, biochemical and immunological parameters of the blood of black-mottled cows for a month before parturition with the developed complex of hematological parameters: hemoglobin 92.24±0.24 g/l, erythrocytes 4.71±0.21 mln/mm³, white blood cells 7.05±0.32 thousand/mm, thrombocytes 219.82±18.5 thousand/mm³, calcium 2.10±0.03 mmol/L, phosphorus 1.10±0.08 mmol/l, alkaline reserve 43.98±1.66 % CO₂, carotene 0.41±0.05 mg%, sugar 35.7±2.37 mg%, total protein 61.23±1.12 g/l, albumins 37.48±0.46 %, globulins 64.52±0.39 %, including beta-globulins 23.68±1.60 %, immunoglobulins: A 117.86±5.33 mg/dl, M 95.08±5.13 mg/dl, G 996.09±16.32 mg/dl; and if obtained results of blood test are lower or equal to the indices of the developed hematological complex, then after birth the risk of postpartum complications increases.

EFFECT: method allows to assess the preparedness of animals for parturition and to predict manifestation of postpartum complications in animals one month before parturition.

Description

The invention relates to the field of veterinary obstetrics and can be used to predict postpartum complications in cows of black-motley breed in the prenatal period.

A known method for predicting the pathology of the postpartum period in cows, the essence of which is to measure the diameter of the navel in newborn calves [4].

The disadvantage of this method is the low prognostic accuracy and the inability to conduct early prevention of postpartum complications, since we obtain the results only after childbirth.

A known method for predicting postpartum diseases in cows, based on vaginal cytology of smears 10-15 days before calving [5].

A known method for predicting postpartum diseases in cows, based on measuring the arterial systolic and diastolic pressure of the cow in the caudal artery [3].

A known method for predicting postpartum endometritis in cows, based on vaginal examination and the time of formation of the mucous plug [6].

The main disadvantages of the known methods are their complexity, low predictive accuracy and the need for reagents and laboratory tests in the economy.

The prototype of the invention is a method for predicting birth and postpartum diseases in cows by examining the biochemical and hormonal indicators of the peripheral blood of pregnant animals for the content of steroid hormones [1, 2].

The disadvantage of the prototype is that it is less accurate and more expensive, since it is necessary to conduct additional studies on hormones, as well as the fact that it is based only on the level of corticosteroid hormones, which does not allow to fully assess the physiological state of the animal and correctly carry out its adjustment with the goal of preventing postpartum complications.

The effectiveness of the use of a complex of hematological parameters for predicting postpartum complications is higher than in the above methods, which is confirmed by significant differences in blood and plasma parameters obtained from animals a month before birth (according to the plan for taking blood in the household) with pathology and without pathology of the birth the postpartum period.

The objective of the invention is to increase the prognostic accuracy of identifying obstetric and gynecological diseases in cows of black-motley breed in the prenatal period through the use of a complex of hematological parameters.

The technical result is achieved by comparing the morphological, biochemical and immunological parameters of the blood of black and white cows a month before birth with the developed complex of hematological parameters: hemoglobin 92.24 ± 0.24 g / l, red blood cells 4.71 ± 0.21 million / mm ³ , white blood cells 7.05 ± 0.32 thousand / mm ³ , platelets 219.82 ± 18.5 thousand / mm ³ , calcium 2.10 ± 0.03 mmol / l, phosphorus 1.10 ± 0.08 mmol / l, alkaline reserve 43.98 ± 1.66 vol. % CO ₂ , carotene 0.41 ± 0.05 mg%, sugar 35.7 ± 2.37 mg%, total protein 61.23 ± 1.12 g / l, albumin 37.48 ± 0.46%, globulins 64, 52 ± 0.39%, including beta globulins 23.68 ± 1.60%, immunoglobulins: A 117.86 ± 5.33 mg / dl, M 95.08 ± 5.13 mg / dl, G 996.09 ± 16.32 mg / dl; Moreover, if the results obtained are lower or equal to the indicated indicators, then in these animals after childbirth the risk of postpartum complications increases, which allows us to assess the preparedness of animals for childbirth and to predict the manifestation of postpartum complications in animals one month before the onset of labor.

The essence of the method lies in the fact that it is carried out by taking blood from cows of black-motley breed a month before giving birth, examining it for morphological, biochemical and immunological parameters, then comparing the results with the developed complex of hematological indicators (Table 1). If the obtained results of blood and its serum are lower or equal to the indicators of the developed complex of hematological parameters, then in these animals after childbirth the risk of postpartum complications increases.

The method for implementing this method is illustrated by an example. Two production experiments were conducted in the SEC them. Kuibyshev and SEC them. "Kalyagin" of the Kinelsky district of the Samara region, studies were conducted for twelve months. The number of animals participating in the production experiment was 600 animals. Based on comparative data on the course of labor and the postpartum period of cows of black-motley breed and analysis of indicators of their blood and plasma obtained from animals a month before the birth, it was found that blood indicators of cows of black-motley breed with pathology and without pathology of the birth and the postpartum period have significant differences. After analyzing the results of morphological, biochemical and immunological studies of blood, we selected animals whose blood counts were lower or corresponded to a complex of hematological parameters, which amounted to 156 animals. The reliability of the developed complex of hematological parameters was 75%, that is, 117 heads of black-motley cows out of 156 showed postpartum complications in the form of subinvolution of the uterus and postpartum endometritis.
