Description

The invention relates to agriculture, namely animal husbandry, and can be used for mass diagnostics of the conditions for the comfortable keeping of young cattle using the thermographic method, as well as for veterinary diagnostics, to determine changes in the condition of the animal depending on the chosen method of keeping and etc.

Most effectively at the moment it can be used in mass diagnostics of preventive examinations in order to identify inconsistencies in the conditions of the physiological state of the animal.

A known method for the recognition of heat-emitting objects by their images, including the formation of a thermal image of the studied object on the screen of a video monitoring device, a visual analysis of this image by the operator with the choice of information zones [1].

The disadvantage of this method is that the operator sets the temperature interval on the video monitoring device to form a thermal image of the test object, sets the number of thermal image decomposition elements, and also creates a frame that defines the real value of the temperature interval in a step-by-step manner.

Thus, in the known method, subjectivity of the perception of the thermal image by the operator is possible, which arises due to its rapid fatigability during mass diagnostics.

Closest to the invention in its essence and the achieved result is a method for determining the radiation temperature of open areas of an animal and detecting the dependence of the radiation temperature of the animal’s body on the ambient temperature [2].

However, the application of this method does not allow to identify the effect of the used technological equipment on the physiological state of young cattle, as well as to evaluate the selected conditions for keeping animals. Thus, the diagnosis of farm animals by the radiation temperature of open zones of animals and the determination of the dependence of the radiation temperature of the animal’s body on the ambient temperature is carried out without taking into account the types of construction (technological) solutions of livestock buildings, without specifying the conditions of young animals and without taking into account the influence of maintenance technological equipment.

The basis of the invention is the development of a method for assessing the conditions of comfortable keeping of calves, which provides higher accuracy in solving problems of matching the construction (technological) solution of the livestock building and the technological equipment used with the physiological state of young cattle.

Common with the known methods signs are recognition of the state of heat-emitting objects from their images, which consists in the formation of a thermal image of the studied object on the screen of a video monitoring device, a visual analysis of this device by the operator with the choice of information zones and the determination of the radiation temperature of the open zones of the animal and the dependence of the radiation temperature of the animal’s body on ambient temperature.

The technical result is an increase in productivity and increase the resistance of the animal organism.

The technical result is achieved by the fact that the method for assessing the conditions of comfortable keeping animals includes recognizing the state of heat-emitting objects from their images, generating a thermal image of the object being examined on the screen of a video monitoring device, visual analysis of this image by the operator with the choice of information zones, determining the radiation temperature of the open zones of the animal - eyes, nose, revealing the dependence of the radiation temperature of the animal’s body on the ambient temperature, and t thermal image of the studied object on the screen of a video monitoring device in the form of thermal imaging cards in static or dynamic mode with saving to a common database in the form of files, take the radiation temperature of the open area of the animal - ears and thermal maps of the temperature of the above-mentioned open areas of the animal’s body for various technological schemes of keeping animal - individual or group way of keeping indoors, in addition, take thermal imaging maps of the temperature of the air surrounding here, and thermal imaging temperature maps of the used technological equipment: technical means of feeding the animal and enclosing structures, compare the temperatures of the studied open areas of the animal’s body in different areas of keeping the animal in the room in different technological schemes, reveal the temperature differences of the studied open areas of the calf’s body in different areas of the selected technological flow chart, simulate the conditions of detention - replace the building envelope with a larger heat conductivity Tew walling on a lower thermal conductivity, change in the animal accommodation according to the presence of "cold" areas used within the animal room to restore normal body temperature of the animal the detection of abnormalities in the animal's body temperature at least 1 ° C.

This set of features allows to increase the accuracy in assessing the conditions for comfortable keeping of calves by examining the thermal (thermographic) image of an animal or group of animals depending on the selected technology for keeping young cattle and the technological equipment used, as well as improving the conditions of keeping the calf from the point of view of creating a comfortable zone for growing the animal, in which the calf receives all the necessary conditions for growth at the optimum temperature ambient air, according to the selected construction (technological) solution of the livestock building and optimization of the corresponding technological equipment. In addition, with the improvement of the conditions of keeping the calves, their productivity (weight gain) increases and the resistance of the animal organism increases with minimal time spent on the assessment of the conditions for comfortable keeping of the calf.

The method is as follows. First, a thermal image of the object under study is formed on the screen of the video monitoring device in the form of thermal imaging cards in static or dynamic mode with the thermal (thermographic) image being saved as files in a common database. Then, thermal imaging maps of the temperature of the following open areas of the calf’s body are removed: ears, eyes and nose, with various technological schemes for keeping the animal — an individual or group way of keeping them indoors or in open or half-open areas, that is, they remove thermal imaging maps of areas containing the greatest amount of information calf body temperature, about the distribution of ambient temperature in the animal keeping area. In addition, thermal imaging cards of the used technological equipment are removed, such as technical means for feeding the calf, enclosing structures, that is, areas from which additional heat can be supplied (technological equipment for feeding the calves during feeding), or the absorption of a certain amount of heat (the presence of enclosing structures with increased thermal conductivity). After that, the temperatures of the studied open areas of the calf’s body in different areas of the animal’s keeping in different technological schemes are compared and the differences in the temperatures of the studied open areas of the calf’s body in different places of the selected technological scheme of the contents are revealed. Determine the presence of deviations in the body temperature of the animal, at least 1 ° C, indicating hyper - or hypothermia of the animal. If necessary, simulate the living conditions until the calf’s body temperature is restored to normal, that is, replace walling with higher thermal conductivity with walling with lower thermal conductivity, change the location of the calf if possible depending on the presence of “cold” zones (according to the ambient temperature) inside the building ( technological) solutions for livestock buildings.

In general, using the proposed method for assessing the conditions of a comfortable calf, the quality and quantity of information obtained in a minimum period of time is increased.

Thus, the proposed method for assessing the conditions of comfortable keeping the animal makes it possible to accurately judge the real picture of the correspondence of the proposed construction (technological) solution of the livestock building and the technological equipment used with the selected method of keeping to the volume (zone) where the calf is located, receiving all the necessary conditions for it growing, and therefore, increases its productivity and increases the resistance of the animal organism.

The proposed method can be practically implemented by using a thermal imager connected to a personal computer such as Pentium class IV and / or higher, as well as a software package through which it is possible to fully implement this method.
