Description

FIELD OF THE INVENTION

The present invention generally pertains to means and methods for measuring body temperatures in poultry.

BACKGROUND OF THE INVENTION

In the last decades, significant development has been done in the genetic selection of the meat-type broiler. These changes have led to rapid growth caused by increased feed efficiency and metabolic rate as well as increased heat production in broiler. However, inferior changes have led to a low capability in maintaining adequate dynamic steady-state mechanisms, under extreme environmental conditions. Thus, exposure of broilers to heat stress results in economic losses caused by longer time needed to reach marketing weight leading to poorer feed conversion and overall lower efficiency of poultry meat production. Sensors distributed in the farm space provide mean values of temperature and humidity, thus, they might present incorrect information about what the broiler actually feel. Extreme thermal conditions may dramatically affect the performance of broilers and other domestic animals, thereby impairing animal welfare and causing economic losses. Although body core temperature is the parameter that best reflects a bird's thermal status, practical and physiological obstacles make it irrelevant as a source of information on the thermal status of commercial flocks. Advances in the technology of infrared thermal imaging have enabled highly accurate, noncontact, and noninvasive measurements of skin surface temperature. This technology enables acquisition of reliable information on the thermal status of animals, thereby improving diagnoses of environmental stress in a flock.

An apparatus and method for facial temperature evaluation using thermal camera (Yahav et al., 2005), is being automatically implemented in this system. Temperature measurement of the individual broiler is of importance for improving climate control system in production house (Giloh et al., 2012).

Poultry welfare is measured in the ambient, namely at the environment within the poultry house. Hence for example, according to the recommendations of Tüller, newly hatched chicks require ambient temperatures of 32 to 35° C., see Tüller R., 1999: Faustzahlen am Geflügelmast. In: Jahrbuch für die Geflügelwirtschaft 1999. J. Petersen (ed.), Verlag Ulmer, Stuttgart, p. 97, incorporated herein as a reference. Alternatively, poltery temperature is detected by invasive manner, i.e., via measuring of cloaca temperature with a small rectal thermometer, see currently available link: https://www.hatchability.com/Chick-temperature.php incorporated herein as a reference. The normal body temperature of a bird is 41° C. A bird is most comfortable and grows faster in ambient temperatures ranging from 10° C. to 20° C. or more. These temperatures are those measured inside the poultry house, at bird level. The bird can tolerate and adapt to temperatures of 20-25° C. but above this heat stress is evident. Thermal analysis of the whole birds' body is known in the art, see Marelli, S. P., et al. “Thermography, a non-invasive method to investigate thermo regulation as welfare indicator in naked neck broiler chickens.” 11th International Conference on Quantitative Information for Red Thermography. 2012, providing for a wide temperature variability. Hence, indirect temperature measurements of ambient in poultry house is not accurate, and is about 20° C. lower than the temperature of the animal itself. Such an indirect and non-accurate measurement leads to many drawbacks, such as decreasing animals' welfare.

CN107549049 The invention relates to an automatic cage-rearing chicken health state monitoring device, and belongs to the technical field of poultry raising. The technical effect that the health state of chicken individuals is judged through the number and body temperature, detected by the automatic cage-rearing chicken health state monitoring device, of the chicken individuals, and missing inspection of manual inspection is avoided. According to the technical scheme for achieving the technical effect, the automatic cage-rearing chicken health state monitoring device comprises a vidicon, a thermal imagery camera, an inspection device, an image processing module, a display module and an alarm, wherein the vidicon and the thermal imagery camera are arranged on the inspection device, the output end of the vidicon and the output end of the thermal imagery camera are electrically connected with the image processing module, and the output end of the image processing module is electrically connected with the display module and the alarm. The automatic cage-rearing chicken health state monitoring device can be widely applied to the field of poultry raising.

There is an unmet need for direct (namely, of a specific predefined organ of the animal), local, reproducible, at least semi-continuous, noncontact and non-invasive temperature measurements of birds in a poultry house.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

It is the object of the current application to describe a system for measuring the temperature of a bird in a poultry house.

In the present application, the term “attractor” refers to a substance that attracts the bird to a specific position within the positioner. The attractor can work on sound, sight or smell. The substance could be a food or an instrument that generates a signal, such as a sound. In one preferred embodiment the attractor is a special food, such as seeds. The attractor can be placed inside a holder or receptacle to better position the birds head. The receptacle can be a hard, solid, container, such as a cup or a gentile pace holder, depending on the type of attractor.

In the present invention, the term “remote sensing instrument” refers to an instrument configured to acquire data about the bird without making contact. In one preferred embodiment the instrument is a thermographic camera.

Reference is now made to FIG. 1 presenting a system (10) for measuring the temperature of birds in a poultry house. The system is constructed from an enclosure (11) that has at least one opening (12). The opening is configured to induce placing a bird's head (17) inside the enclosure (11) and reach an attractor (16) placed in a receptacle (13). Solid and liquid foods are in the scope of the present invention, A remote sensor instrument (14) and the receptacle (13) accommodating the attractor (16) are mutually disposed such that the bird's head (17) is within a field of view of the remote sensor instrument (14) in order to acquire a thermal reading of the bird, according to one embodiment, the remote sensor instrument (14) is a thermographic camera configured for taking at least one image of a specific area of birds' head near the eye and beak.

In one embodiment, the system also includes an external temperature sensor (18) that enables calibrating the remote sensing instrument (14). The temperature sensor selected from the group consisting of resistance thermometers (such as a PT100), thermocouples or thermistors. The calibration is conducted in real time and/or intermittently.

Reference is now made to FIG. 2 presenting a method (20) for measuring the temperature of birds in a poultry house. The enclosure (21) is placed in a poultry house. When the bird is positioned in front of a remote sensor instrument (22) a reading of the bird is generated. The remote sensor instrument is configured to take multiple readings of a single bird. The reading(s) are entered into a computation system (23) that is configured to decode the reading and generate a temperature measurement (24). The computation system (23) generates measurements using multiple readings and multiple data points within each reading by using a weighted average of the readings and of the temperature measurement of each data point within each reading.

Reference is now made to FIG. 3 presenting a system (100) for regulating the environmental conditions of a poultry house. The regulation system comprises a number of measuring modules (102) placed within a poultry house (101). The measuring modules are spread-out throughout the poultry house to enable a sampling of the poultry population in the house. The measuring modules (102) transmit the readings to a computation module (103). The computation module generates temperature measurements and regulates the environmental control units (104) placed throughout the poultry house. In one preferred embodiment of the current invention, the environmental control systems are air conditioners, cooling pads, vitrines, heaters and ventilators of all kinds. In another preferred embodiments the environment of the poultry house can be regulated by a combination of the various technologies listed above. The computation module (103) is configured to read input from additional sensors (105) that measure additional environmental parameters, such as air temperature, humidity etc.

Reference is now made to FIG. 4 presenting a method (200) for regulating the temperature in a poultry house. A measuring module (201) is placed in the poultry house, together with birds. A temperature reading in conducted (202.i) and the temperature is calculated (202.ii) and communicated to the control unit (203).

The control unit (203) is configured to regulate the poultry house climate according to various parameters: Average body temperature readings of individual birds; Number of birds whose body temperature is outside of a designated “comfort zone”; and Environmental readings.

In some embodiments, the control unit uses a combination of the listed parameters.

The settings are dependent on a number of variables, such as the species of bird in the poultry house, the outside climate, the season etc.

If the temperature is within the optimal range then the environmental control unit settings are not changed (204). If the temperature is outside the optimal range then the environmental control unit settings are recalculated (205). The steps of conducting temperature readings (202), communicating's the measurements to the controller (203) and resetting environmental control units (204, 205), are repeated to enable continuous regulation of the poultry house climate. Requirements to climate control are defined by European Council Directive 2007/43/EC of 28 Jun. 2007.

It is experimentally shown that the system of the present invention is able to sense the poultry body temperature in a production house and automate monitoring over a broiler stock without human intervention. By implanting temperature loggers and RFID tags into the birds, the thermal images of individual birds and the corresponding body temperature measured by the loggers were pared. Using the paired set of data consisting of logger temperatures and the matching thermal images, a model that predict body temperature of the bird by using a thermal image was built. FIG. 5 shows the correlation between face temperature and body temperature (R²=0.923478). The model results, as seen in FIG. 6, confirm that body temperature can be measured using low cost thermal camera. This fact enables the future development of a thermal commercialized system.
