Types Of Higher Nervous Activity Research Articles

Studying the relationship of the type of higher nervous activity with the milk productivity of cows

The purpose of the presented research was to study the influence of the type of higher nervous activity (HNA) on the secretion of organic components of milk in various milking conditions. The studies were carried out in 2 periods. The first period was standard, and in the second there was a conditioned stimulus - the presence of an outsider. Black-and-white cows were assigned to four types of higher nervous activity: type 1 - strong, balanced; type 2 - strong, unbalanced; 3 - strong, inert; 4 - weak, inhibitory. In the first period, type 2 cows showed a significant decrease in the amount of milk, fat and glucose, but the mass fraction of protein in milk tended to increase separately for each milking by 0.22 %. The ratio of the mass fraction of protein to the percentage of lactose for two milkings was significantly higher by 0.06, in relation to type 1. In type 3, in general, for two milkings, an increase in lactose by 13.3 g, fat - by 7.0 g was noted, in contrast to the indicators of the first type. Animals of the fourth type tended to reduce milk secretion to 18.3 %. Also, the mass fraction of fat in milk was lower to 0.53 % (P < 0.05) and protein to 0.28 %, and the proportion of lactose in milk, on the contrary, was consistently higher in both milkings by 0.25-0,26 % (P < 0.05). In the second period (with a conditioned stimulus), cows of the second group showed a positive trend towards an increase in the mass fraction of protein in the morning with machine milking by 0.26 % (P < 0.05), and with manual milking by 0.32 % (P < 0.05), in relation to the first group. The mass fraction of fat during machine and manual milking in animals of the second type tended to decrease. In the third group, the indicators of milk of the first streams in the morning were higher by 0.99 % (P < 0.05) - fat, by 0.33 % - protein, by 0.09 % - lactose, in relation to the first type of higher nervous activity. In cows with a weak, inhibitory nervous system, the influence of the conditioned stimulus contributed to a decrease in the ratios of the mass fraction of fat and protein in milk to lactose to 0.14 and 0.09, compared with type 1 cows.

HEART RATE VARIABILITY IN FOOTBALL PLAYERS AND TRACK AND FIELD ATHLETES

Objective of the study: To investigate the state of the autonomic nervous system in athletes based on heart rate variability indicators. Materials and methods: The study was conducted on 142 male athletes (67 football players and 75 track and field athletes) aged 17-20 years, with an average age of 18.5±1.5 years. Depending on the type of higher nervous activity, athletes were divided into 4 groups: sanguine (41.55%), choleric (28.87%), phlegmatic (19.01%), and melancholic (10.56%). Heart rate variability (HRV) was studied using the "BioMouse" system. A t-test for independent samples (Welch's t-test) was used to analyze the significance of differences between the groups. Results of the study: It was found that the highest adaptive capabilities were observed in phlegmatic athletes, who demonstrated high SDNN and HF values, as well as a low tension index (IN). Their calm temperament allows for better adaptation to physical exertion and maintaining a balance between sympathetic and parasympathetic activity. The lowest adaptive capabilities were observed in melancholics, who showed high IN and LF values, as well as low SDNN and HF, indicating an imbalance in the autonomic nervous system and lower resilience to physical stress. Overall, beginner athletes tended to have slightly higher heart rates and lower HRV indicators (SDNN), LF, and HF compared to more experienced athletes of the 2nd-3rd ranks. This is due to the fact that first-year athletes have not yet fully adapted to physical loads, leading to more pronounced dominance of the sympathetic nervous system and less parasympathetic activity. KEYWORDS: variability, heart rate, athletes, football players, track and field athletes, autonomic nervous system, physical exertion

ANALYSIS OF THE DAIRY PRODUCTIVITY OF MARES NOVOOLEKSANDRIVSKA DRAFT BREED TAKING INTO ACCOUNT THE TYPE OF HIGHER NERVOUS ACTIVITY

The results of the analysis of the quantitative indices of milk yield of the mares of the Novo-Alexander weight-carrying breed and the determination of their type of higher nervous activity are given. The research was carried out using the motor-forage technique and monthly control milkings for two adjacent days. On the basis of the obtained data, the highest indicators of breeding in the herd were established in June. Record-breaking mares (Rizba, Fibr-ra) were identified according to the individual level of productivity, whose milk yield was more than 2000 liters per lactation, with an average value of1, 331 liters. Mares with a strong balanced mobile type of higher nervous activity prevailed in number and were characterized by significantly higher milk yield (p ˂ 0.05) compared to mares with a strong balanced inert and strong unbalanced type of higher nervous activity.

STATE OF OXIDANT HOMEOSTASIS IN THE BODY OF DOGS WITH DIFFERENT TYPES OF HIGHER NERVOUS ACTIVITY

The relevance of the study is due to the lack of data on the cortical mechanisms of regulation of the activity of the antioxidant defense system in the body of dogs. In this regard, this article is aimed at revealing the specifics of the activity of key enzymes of the system of antioxidant protection of the blood of dogs with various types of higher nervous activity under the influence of short-term food deprivation. It was shown that short-term food deprivation in dogs caused a stressful state, which was accompanied not only by a change in the behavior of the animals, but also reflected the state of the enzymatic link of the antioxidant defense system in their body. In particular, a significant effect of short-term food deprivation on the activity of catalase in dog blood erythrocytes was established (F = 13.7 > FU = 4.15; p < 0.001). We note the increase in the influence of the force of nervous processes on the activity of catalase in the blood of dogs during the experiment from – gh²ᵪ = 0.20 (р < 0.05) in the intact state, to the indicator – гх²ᵪ = 0.68 (р < 0.001) by the third day of research. Also, under the influence of food deprivation, direct connections of the strength and balance of nervous processes with the activity of this enzyme appear (r = 0.52–0.78 (р < 0.05–0.001). Under such influence, after one day and three days after the action of the stress factor, the activity of catalase in the blood of dogs with a weak type of higher nervous activity is lower by 3.6–5.8% (P < 0.05) than that of dogs with a strong balanced mobile type of higher nervous activity blood erythrocytes also found a decrease in the activity of the glutathione link of the antioxidant protection system in the blood plasma of dogs, in particular, under the influence of a stress factor, the activity of glutathione reductase during the day in dogs with various types of higher nervous activity decreases by 11.6–16.9%, respectively (р < 0, 05–0.01), the activity of glutathione reductase also decreases. Prospects for further research consist in the development of new methods for the correction of substance metabolism based on the use of nanoaquachelates of biogenic metals, taking into account the individual characteristics of the dog’s body.

Influence of the type of higher nervous activity on seminal physiological characteristics in cats of Russian breeds

Temperament has a significant impact on reproductive function. Most studies are devoted to temperament as a mental characteristic, and the sexual temperament of cats and its influence on physiological characteristics of sperm have not been studied at all. The aim of the research was to study physiological features of reproductive function in cats of Russian breeds depending on sexual temperament. The experiments were carried out in Moscow and the Moscow region from 2019 to 2022. The study used 21 breeding mature cats aged 2 to 8 years, which belonged to 5 different Russian breeds (Bengal breed - 5 cats, British shorthair - 5 cats, Siberian breed - 6 cats, Maine Coon - 5 cats, Sphinx - 5 cats). The sexual temperament of cats was determined according to our methodology developed on the basis of modification of the method for determining the sexual temperament for stallions. Mobility of native sperm was the lowest in cats with a weak nervous system, which is 1.17 % less than mobility of sperm in animals with an unbalanced nervous system, 7.36 % less (P 0.01) compared to physiological mobility of newly acquired sperm in an inert nervous system and 9.71 % less than activity of sperm in cats with a sanguine temperament. The highest concentration of sperm was in cats with live sexual temperament, which was 3.02 million/ml more (P 0.05) than in cats with unrestrained type of temperament, 43.09 million/ml more (P 0.01) than in cats with calm sexual temperament and 56.74 million/ ml more (P 0.01) than in cats with weak sexual temperament. Sperm motility after thawing was higher in cats with inert temperament, which was 5.06 % more (P 0.01) compared to cats with mobile temperament and weak nervous system and 9.1 % more (P 0.001) than in unbalanced cats. Survivability of germ cells in Russian cats at 38 C after defrosting was greatest in live sexual temperament cats, which was 0.22 hours more in comparison with calm sexual temperament cats, 0.62 hours more (P 0.01) than in cats with weak sexual temperament and 0.91 hours more than in cats with unrestrained sexual temperament.

Indicators of protein exchange in dogs with different types of higher nervous activity

The relevance of the study is due to the current lack of data on cortical mechanisms of protein metabolism regulation in dogs, which is important to consider when developing methods of corrective action on metabolism. The aim of the study was to determine the peculiarities of protein metabolism in dogs with different types of higher nervous activity, and to establish the relationship between the main characteristics of nervous processes and indicators of protein metabolism in the blood. The leading method in the study of this issue was a new method for determining the typological features of the nervous system in dogs, and the obtained scores of strength, balance, and mobility of nervous processes helped to identify the degree of their influence on protein metabolism. A significant effect of short-term nutritional deprivation on the content of certain indicators of protein metabolism in the blood of dogs, depending on their temperament, was established. Under the action of the stimulus during the day, a decrease in the level of albumin and changes in the ratio of globulins were observed in the blood of dogs, in particular, an increase in the relative content of α- and β-globulins and a decrease in γ-globulins. It was determined that the type of higher nervous activity has a significant effect on the content of total protein, albumin, globulins, β-globulins, γ-globulins and the value of the albumin-globulin ratio (F=3.02-14.6>FU=2.90; P<0.05-0.001) in the blood plasma of dogs. A direct relationship between the strength of nervous processes and the content of total protein and albumin, γ-globulins (r=0.62-0.73; P<0.01) and an inverse relationship between the content of αand β-globulins (r=-0.51-0.56; P<0.01) was found three days after the onset of short-term nutritional deprivation. The balance of nervous processes was inversely related to the content of β-globulins (r=-0.44; P<0.05). The fundamental knowledge gained is of practical value for the development of new, modern methods of metabolic correction taking into account the temperament of animals

Рsychological training of freestyle wrestling athletes

The article examines the psychological preparation of freestyle wrestling athletes, which, along with technical, physiological and tactical training, is one of the most important conditions for the athlete's functional preparation for successful competition. The object of such training is always the athlete's personality with its individual characteristics and typical features.
 The article analyzes the importance of psychological preparation of freestyle wrestling athletes for the development of strength, speed of reaction, strength and endurance and, as a result, victory in the match.
 Free wrestling is a powerful means of learning self-defense skills and comprehensive development of the most important physical qualities: strength, speed, dexterity, coordination, reaction speed. From a psychological point of view, free wrestling contributes to a person's self-confidence, the development of demandingness, patience, courage, initiative, attentiveness and non-standard thinking. As we can see, the physical and mental aspects of an athlete's personality are inextricably linked, and the mental aspect contributes to the development and manifestation of the physical aspect, and is the basis for its formation. Such a dialectical understanding of the relationship between these two processes aims coaches at the constant improvement of the psychological functions and qualities of martial arts athletes.
 Success in sports activities of wrestlers is associated with the timely use of various means and methods of training, while it is important to take into account the peculiarities of education and strengthening the specific mental qualities of an athlete. The impact of pedagogical factors aimed at the formation of personality, taking into account the types of temperament of athletes, can help increase motivation for training.
 Sports specialists point to a significant dependence of a person's physical capabilities on the properties of the types of higher nervous activity (temperament), therefore, athletes belonging to different types of temperament should go to high sports results in different ways. The problem of individualization of the training process, taking into account individual peculiar properties, the psyche, also acquires practical significance.

Dynamic Changes Of Physiological And Psychological Parameters Of Young Persons As Asthenia Risk Factors

Asthenic syndrome is the most important problem of the modern stage of development of human society, which is the most important component of many pathological conditions or risk factors for diseases. The purpose of the study is to determine some physiological and psychological parameters in young people in dynamics at different levels of intellectual load and evaluate their role in the formation of asthenic syndrome. Materials and Methods: The study involved 160 3rd year students of the Medical Institute of Moscow State University. N.P. Ogarev, divided into four groups according to the type of higher nervous activity (HNA), based on the indicators "Extraversion / Introversion" and "Neuroticism", determined by the Eysenck scale. We assessed the characteristics of emotional balance, functional parameters of autonomic regulation, features of cognitive functions in young people in different periods of training load. Results: the indicator of neuroticism correlated with the severity of asthenic syndrome in young people. Persons with a high level of neuroticism more often revealed maladjustment of mental processes, a decrease in cognitive functions, and an increase in emotional instability during the period of intense intellectual loads. After a period of increased intellectual load, asthenia occurs significantly more often in females. Features of autonomic regulation have little effect on the development of asthenia. The exceptions were individuals with a high level of neuroticism. In these groups, the stress of hemodynamic mechanisms was occurred frequently.

Evolutionary morphology of spinal nodes of poikilotherm vertebrate animals

An important issue of modern neuromorphology of animals is the study of spinal cord nodes, which play an important role as primary centers on the way to transmit sensory information from receptors to the central nervous system, providing appropriate reactions to the action of certain factors. The scientific article uses material that is a fragment of the research work of the department of normal and pathological morphology, hygiene and expertise “Development, morphology and histochemistry of animal organs in normal and pathological conditions”, state registration number – 0120U100796. Using anatomical, morphological, neurohistological and statistical methods of research, the histomorphology of spinal cord nodes in a comparative anatomical series of vertebrates: bony fish, amphibians, reptiles, which differ in motor activity and their place of existence in a certain environment, was clarified in the work. It has been established that in the process of phylogenesis, a certain structural and morphofunctional reorganization of the spinal nodes occurs. They differ in shape and size. Adaptation to various living conditions of animals was formed on the basis of changes in the density and size of neurons, their morphological structures, an increase in the total number of gliocytes and glial cells, and polymorphism in the degree of chromatophilia. Thus, according to neurohistological studies, it has been noted that the neurons of the spinal cord nodes of cold-blooded animals (pond frog, pond lizard) are characterized by a functional degree of relative polymorphism – chromatophilia. With the total impregnation of the spinal cord nodes with silver nitrate according to the Bolshovsky-Gross method, different intensity of staining of nerve cells is found in all the studied animals: light, light-dark and dark. It was found that the neurocytes of all groups of vertebrates differ in the volume of the perikaryon, the nucleus and the nuclear-cytoplasmic ratio, which is related to the peculiarities of species and age-related neuromorphology, the morpho-functional state of the nervous system and the type of higher nervous activity. Nissl staining of histopreparations of spinal nodes of poikilothermic animals showed that the neuroplasm of nerve cells of spinal nodes contains deep basophilic substances in the form of small grains of varying density. In carp neurons, the basophilic substance is concentrated on the periphery of the dust-like neuroplasm. Nuclear chromatin is more pronounced in the pond frog than in the carp, the depths of which are much larger. It should be noted that the highest degree of development of the protein-synthesizing apparatus is characteristic of the neurocytes of the spinal nodes of the swift lizard, compared to the previously studied vertebrates. The obtained research results have not only important general biological significance, which complements and expands modern scientific ideas about certain regularities of morpho-functional rearrangements of spinal cord nodes in a comparative anatomical series, but also serve to develop new material and substantiate the morpho-functional assessment of species morphological differences of the nervous system of poikilothermic vertebrates, adapted to different conditions of existence in the environment.

Study of the influence of the type of higher nervous activity on the secretion of organic components of milk

The purpose of the experiment was to study the influence of the type of higher nervous activity (HNA) on the secretion of organic components of milk in various milking conditions. Under the influence of the unconditioned stimulus "inadequate udder preparation" in the milk of machine milk in cows in the morning milking: I HNA type - secretion and percentage of milk fat and the ratio of percentage of fat to percentage of lactose decreases, while in all other types there is a decrease in the percentage of fat and protein. In the unbalanced (II) type, the average duration of the milk flow cycle decreases; in the inert (III) and weak (IV) type, the concentration of fat and lactose decreases, and the ratio of fat to lactose in the latter. It is advisable to characterize the stress resistance of animals based on knowledge of their types of HNA. At the same time, the complexity of their determination by known methods should be noted. In dairy farming, it is necessary to provide for the presence of all types of HNA among the cows and take into account their individual characteristics in terms of resistance to stress, the level of milk production and milk yield. It is recommended to apply the model of dairy cows developed by us to objectively determine the type of their stress resistance in production conditions. The presented patterns of changes in the secretory function of the mammary gland under the influence of tested stress factors on dairy cows of different types of higher nervous activity should be used to develop express methods for determining the types of stress resistance in animals and completing the herds of dairy farms.

Specific features of the morphology of the spinal nodes of homeothermal vertebrate animals in the comparative and anatomical series

Scientific studies that reflect the evolutionary morphology of the nervous system, namely the spinal nodes of homoeothermic vertebrates, allow us to identify specific patterns, trends, and criteria that relate to the structural organization of the organ at the population and cellular levels of their organization. The evolutionary direction of research into the macro- and microstructure of spinal cord nodes provides an opportunity to investigate the patterns of formation of optimal relationships of their structural components: nerve and glial cells, capillaries concerning the level of development of the organism, and their motor activity. The article contains the results of the morphometric characteristics of the spinal nodes of warm-blooded vertebrates in a comparative aspect: class Aves – Birds (Gallus gallus, forma domestica L., 1758 – domestic chicken); class Mammalia – Mammals (Oryctolagus cuniculus L., 1758 – European krill, Canis lupus familiaris L., 1758 – domestic dog, Sus scrofa, forma domestica L., 1758 – domestic pig, Bos taurus taurus L., 1758 – domestic bull). When performing this work, complex research methods were used: anatomical, neurohistological, morphometric, and statistical. The morphological study of the structural components of the organs of the nervous system was studied on histological sections by the method of light microscopy following the requirements of the international principles of the “European Convention for the Protection of Vertebrate Animals Used in Experiments and for Other Scientific Purposes” (Strasbourg, 1986), a decision of the First National Congress on Bioethics (Kyiv, 2001), Law of Ukraine No. 692 “On the Protection of Animals from Cruel Treatment” (3447-IV) dated February 21, 2006. For histological examination, the newly selected material was immediately fixed in a 10% aqueous neutral formalin solution, with a fixation period of 30 days, followed by step-by-step embedding in paraffin. Using a sled microtome, histological sections with a thickness of 6–10 μm were obtained. The general histological structure and microstructural changes in histological preparations were studied under a light microscope MC (Micros Austria) at magnifications from 70 to 600 times. Photomicrographs of histological preparations were carried out using a CAM V200 video camera mounted in a Micros MC microscope. The work aims to conduct a complex morpho-functional study of spinal nodes in a comparative anatomical series of representatives of higher vertebrates. It was investigated that in phylogenesis, a particular structural and morphofunctional rearrangement of the central and peripheral nervous system organs, namely the spinal nodes, takes place. They differ in shape and size. It was established that the neurocytic organization of the spinal cord nodes of all species of animals studied is characterized by the presence of large, medium, and small nerve cells. Adaptation to various living conditions of animals was formed based on morphometric indicators (the volume of neurocytes and their nuclei), their morphological structures, the density of nerve cells per 0.1 mm2, the number of glial cells per 0.1 mm2, an indicator of nuclear-cytoplasmic ratio, degree of polymorphism chromatophilia. Nissl staining of histopreparations of spinal nodes of homoothermic animals showed that the neuroplasm of nerve cells contains well-defined depths of basophilic substance, compared with lower animals, as evidence of a higher degree of development in nerve cells of the protein-synthesizing apparatus. According to the method of impregnation of spinal cord nodes with silver nitrate in all studied animals, a different intensity of coloring of nerve cells is revealed: dark, light-dark, light, which is related to the peculiarities of species and age neuromorphology, the morphofunctional state of the nervous system and the type of higher nervous activity. The obtained morpho-functional features of the organs of the nervous system are essential not only for evolutionary and comparative morphology but also for developing issues of physiology, pathology, and treatment of peripheral nervous system diseases.

ANATOMICAL AND HISTOLOGICAL ASPECTS OF THE EVOLUTIONARY MORPHOLOGY OF THE SPINAL NODES OF VERTEBRATES ANIMALIUM

Using anatomical, histological, neurohistological and morphological research methods, the histomorphology of spinal cord nodes in a comparative anatomical series of vertebrates: bony fishes, amphibians, reptiles, birds and mammals, which differ in their motor activity and their place of existence in a certain environment, was clarified in the work. It has been established that in the process of phylogenesis, a certain structural and morphofunctional reorganization of the spinal nodes occurs. They differ in shape and size. Adaptation to various living conditions of animals was formed on the basis of changes in the density and size of neurocytes, an increase in the total number of gliocytes and perineuralneglia cells, and polymorphism in the degree of chromatophilia.
 Thus, according to neurohistological studies, it has been noted that the neurons of the spinal cord nodes of cold-blooded animals (pond frog, pond lizard) are characterized by a functional degree of relative polymorphism – chromatophilia.
 Impregnation of spinal cord nodes with silver nitrate in all studied animals revealed different intensity of staining of nerve cells (light, light-dark, dark), which is related to the specifics of species and age-related neuromorphology, the morpho-functional state of the nervous system and the type of higher nervous activity.
 An important issue of modern neuromorphology of animals is the study of spinal cord nodes, which play an important role as primary centers on the way to transmit sensory information from receptors to the central nervous system, providing appropriate reactions to the action of certain factors.

 The obtained results of the research have an important general biological significance, which complements and expands the idea of certain regularities of spinal nodes, which relate to their structural organization and comparative characteristics at the cellular and tissue levels in vertebrate animals of various species.

FEATURES OF CARBOHYDRATE-LIPID METABOLISM IN DOGS WITH DIFFERENT TYPES OF HIGHER NERVOUS ACTIVITY

The relevance of the study is due to the lack of data on the cortical mechanisms of regulation of carbohydrate and lipid metabolism in the body of dogs. In this regard, this article is aimed at revealing the issue of lipid and carbohydrate metabolism in dogs with various types of higher nervous activity under the influence of short-term food deprivation. It is shown that the effect of short-term food deprivation is characterized by changes in metabolism in the body of dogs, which are limited by the state of the nervous system of these animals. In the intact state, the glucose content in the blood of dogs with different types of higher nervous activity does not reliably differ, while the lactate content in the blood of dogs with a weak type of higher nervous activity is higher by 16.2% (P < 0.01), and pyruvate is lower by 6.3% (P < 0.001) from the indicators of dogs with a strong balanced mobile type. Within a day after the beginning of food deprivation, the glucose content in the blood of dogs decreases by 4.6–8.2% depending on the type of nervous activity (P < 0.05–0.01). During the day after the beginning of deprivation, the ratio of lactate to pyruvate in the blood of dogs, depending on the type of higher nervous activity, increases by 19.1–36.0% (Р < 0.01), the content of total cholesterol and triacylglycerols in the blood plasma decreases by 3, 5–12.9% and the ratio of lipids of different densities changes significantly. In particular, in the blood plasma of dogs of a strong balanced mobile type of higher nervous activity, the cholesterol content of high-density lipoproteins decreased during the day by 7.1% (Р < 0.05). Thanks to the conducted research, it was possible to obtain fundamental knowledge of the cortical mechanisms of regulation of carbohydrates and lipids in the body of dogs, which will form the basis of the development of new, modern methods of correction of metabolism, taking into account the type of higher nervous activity. Prospects for further research consist in the development of new methods of correction of metabolism based on the use of nanoaquachelates of biogenic metals, taking into account the individual characteristics of the body of dogs.

A significant influence of the type of higher nervous activity on the content of total protein (F = 11.2 > FU = 2.90; Р < 0.001), albumins (F = 14.6 > FU = 2.90; Р < 0.001), globulins ( F = 3.02 > FU = 2.90; P < 0.05), β-globulins (F = 4.07 > FU = 2.90; P < 0.05), γ-globulins (F = 5, 52 > FU = 2.90; P < 0.01), lactate (F = 36.2 > FU = 2.90; P < 0.001) and pyruvate (F = 4.1 > FU = 2.90; P < 0.01), total cholesterol (F = 4.1 > FU = 2.90; P < 0.05) and triacylglycerols (F = 4.9 > FU = 2.90; P < 0.01) in the blood of dogs . Then, as the influence of higher nervous activity on the content of glucose (F = 0.69 < FU = 2.90; p = 0.56) and α-globulins (F = 1.50 < FU = 2.90; p = 0, 24) was not detected in the blood plasma of dogs. Short-term food deprivation also had a significant effect on the content of glucose (F = 18.7 > FU = 4.15; P < 0.001), β-globulins (F = 39.3 > FU = 4.15; P < 0.001), γ- globulins (F = 11.7 > FU = 4.15; P < 0.001), albumins (F = 19.1 > FU = 4.15; P < 0.001), globulins (F = 7.71 > FU = 4, 15; Р < 0.01), lactate (F = 50.0 < FU = 4.15; Р < 0.001), pyruvate (F = 20.7 < FU = 4.15; Р < 0.001), total cholesterol ( F = 5.7 < FU = 4.15; P < 0.05) and triacylglycerols (F = 11.5 < FU = 4.15; P < 0.01) in the blood of dogs. The influence of food deprivation on the content of total protein (F = 0.44 < FU = 4.15; p = 0.28) and α-globulins (F = 0.88 < FU = 4.15; p = 0.36) in the blood of experimental dogs has not been determined. During the entire experiment, no interfactorial interaction between short-term food deprivation and the type of higher nervous activity was established (F = 0.01–1.29 < FU = 2.90; p = 0.29–1.00), which indicates the absence of the influence of deprivation on the type of higher nervous activity of animals.

PECULIARITIES OF TRAINING OF SERVICE DOGS BY DOG SPECIALISTS

The article considered a comparative characteristic of the compatibility of temperaments of cynologists and service dogs for training in a cynological center. The results of studies on the study of types of higher nervous activity in cynologists and service dogs are presented in order to determine the effectiveness of their training.

Influence of the types of higher nervous activity in cows on the milk flow process

The aim of the research was to study the effect of the type of higher nervous activity on the excretory function of the mammary gland. Cows are classified according to the types of higher nervous activity (HNA): First type - strong, balanced, mobile; Second type - strong unbalanced; Third type - strong inert; Fourth type – weak breaking. Under standard milking conditions, in cows of the first higher nervous activity type there were observed: a tendency or a significant increase in single milk yield and milking time in comparison with other types. The conditioned stimulus “foreign milkmaid”, when applied once or twice, caused an increase in the number of milk flow cycles in first and second higher nervous activity type cows with a decrease in the duration of one cycle both in the morning and lunchtime milking, compared with standard conditions. The following positively correlates with the intensity of milk flow: single milk yield, the milk flow rate for the first and second minutes of milking and maximum, the percentage of milk yield for the first and second minutes, the number of milk production cycles for two, three minutes and in general for milking. Negatively correlates the time of milk yield, the achievement of the maximum rate of milk flow and the total milking time. The process of inhibition of milk flow weakens these connections. The type of higher nervous activity in cows affects the relationship of indicators of milk flow both under conditions of varying degrees of readiness for milk flow, and action of conditioned and unconditioned stimuli on the animals used in the experiment.
