AGE VARIABILITY AS ONE OF THE MOST IMPORTANT PREGNANCY PLANNING RESERVES AND FORECASTING ITS CURRENT IN COWS
The article is devoted to predicting the time critical for the development of fetoplacental insufficiency. The relevance of the study lies in the fact that the problem of managing the processes of reproduction of cattle, increasing its fertility and preventing infertility is of particular relevance in connection with the introduction of industrial methods of keeping animals. The purpose of our research is to further study the main directions of prevention of fetoplacental insufficiency in cows and methods of its detection. The main result of a normal pregnancy is the birth of a healthy offspring [1]. Consequently, all the activities of the mother’s body during the pregnancy are aimed at ensuring the normal development of the fetus and those genetic potencies that are embedded in the fertilized egg, implanted in the uterus. Methodology. A change in the mother’s condition affects actively the development of the fetus; moreover, this impact is determined not only by genetic laws. In the reproduction of farm animals, the degree of mutual influence of the mother and the fetus is largely determined by the conditions of keeping and feeding the breeding stock. These conditions have a direct impact on the extensive list of regulatory and executive mechanisms that ensure the functioning of the mother-placenta-fetus system. Results. Most of the causes and conditions leading to infertility or the birth of a weak and unviable offspring are considered by specialists in a causal relationship with a violation of the structure and function of the fetoplacental system. Unfortunately, such violations, which are called fetoplacental insufficiency in medical practice, are poorly generalized in the veterinary literature. In recent years, with some manifestations of fetoplacental insufficiency in animals, the life periods of predisposition to it in females of various species have not been established, and there are no comprehensive recommendations for the prevention and treatment of fetoplacental insufficiency in animals, taking into account all the etiopathogenetic factors of this disorder. In recent years, with some manifestations of placental insufficiency, certain pharmacological preparations began to be used to stimulate the reproductive functions of animals, the renewal of secretory activity and neuromuscular tone of the genitals. The effectiveness of these drugs in many cases turns out to be low, especially when they are used without taking into account the conditions of keeping animals, their physiological state, the course of their metabolic processes, and finally, without taking into account the immunobiological reactivity of their organism. In this regard, the response of the body to the introduction of medicinal substances is not always the same. Scientific novelty. The only way to eliminate placental insufficiency is its timely prediction, including on the basis of studying the features of ontogenetic transformations of the mother’s body, knowledge of the physiological age patterns of a pregnant female with predicting critical and favorable terms for the course of pregnancy, bearing healthy and genetically valuable offspring. These activities are possible only on the basis of understanding the need to grow a healthy and full-fledged mother herd, understanding the essence of the relationship between the mother’s body and the fetus during pregnancy.
