The present invention relates to a portable kit for pregnancy detection in livestock using urine sample and its method of use. More specifically, the present invention provides a quick, simple and onsite testing kit for pregnancy estimation in livestock comprising a combination of two solutions acidifying agent and colour developing agent in a vehicle, wherein kit helps to develop a red colour in presence of Abscisic acid (about 10 μg/ml and above) as indication of pregnancy and Yellowish orange colour at lower concentration of Abscisic acid as indication of non-pregnancy. Therefore, a kit provides colour based pregnancy detection in livestock using animal urine which provides ease of testing and immediate results. The portable kit would be particularly useful in field or rural settings where laboratory equipment, chemicals, and refrigerated storage are unavailable.

The present invention relates to a method of improving a reproductive potential of a male mammal using an ultra-weak photon. The ultra-weak photon according to the present invention is in a visible light spectrum but is transmitted as weak light that is not visually recognized so that the ultra-weak photon does not provoke stress and can be irradiated safely for a long time, thereby improving the reproductive potential of male mammals. Unlike an existing material feeding method of improving a reproductive potential, in which a material is supplied wastefully and environmental pollution problems are caused due to tolerance and misuse, the present invention relates to a useful alternative technology that can be used for a long time and ensure the sustainability of livestock industries.

This document describes devices and methods for suturing an anastomosis. For example, this document describes transurethral probe devices that can be used to suture a vesicourethral anastomosis with one continuous stitch along a helical toroidal path.

A physiological condition determination system and method can include: attaching a tag to animal tissue; emitting light into the animal tissue; detecting a first optical signal; extracting a first measurement of peripheral capillary oxygen saturation from the first optical signal; qualifying the first measurement of peripheral capillary oxygen saturation as a baseline; detecting a second optical signal with the optical sensor; extracting a second measurement of peripheral capillary oxygen saturation from the second optical signal; qualifying the second measurement of peripheral capillary oxygen saturation; storing the second measurement of peripheral capillary oxygen saturation as a tag feature set; storing a history; determining animal distress based on the difference between the second measurement of peripheral capillary oxygen saturation and the baseline; and sending an instruction to the tag.

A method of managing a disease and an apparatus performing the same are provided. The method of managing livestock disease includes receiving biometric information of livestock from a biosensor capsule settled in a body of the livestock, detecting a singular point deviating from a reference value, based on the biometric information, monitoring a health state by increasing a disease probability of the livestock when the singular point is detected, and detecting a disease by determining an abnormality in the health state of the livestock when the disease probability of the livestock is a first threshold value or more. An animal subject suspected of reproductive disorders (ovarian cyst) may be rapidly detected, and intensive care (veterinary examination and hormone prescription) may be provided to the farm, thereby increasing productivity of the farm.

The present invention is directed to methods for fertility prediction in animals, and in particular dairy cows. The methods allow detection of the likelihood of conception upon insemination of a cow based on the analysis of properties of milk of the cow, and in particular the mid-infrared (MIR) spectrum of the milk. Such methods also enable selection of cows for insemination and fertility classification of cows. Software and systems for carrying out the methods of the invention are also provided. The present invention also provides methods for deriving reference MIR spectra representative cows with good or poor likelihoods of conception upon insemination. These reference MIR spectra can be used for fertility prediction in cows to be tested.

In one embodiment, the present invention provides an intrauterine device (IUD) comprising an oval shape, wherein the device comprises a core of magnetic material, an inert material or copper coating the core, wherein the coating comprises a pharmaceutical agent, copper or a combination thereof. Another embodiment provides a method to suppress estrus in a subject comprising inserting an intrauterine device (IUD) comprising an oval shape, wherein the device comprises a core of magnetic material and an inert material or copper coating the core.

A method and system for managing animal data are disclosed. The system for managing animal data includes: a sensor inserted into the body of an animal or attached to the outside of the animal's body to provide an identifier of the animal; a first reader installed at a start portion of a passage through which the animal passes to receive the identifier of the animal from the sensor inserted into or attached to the animal when the animal moves past the start portion or the first reader and to identify a first time of receipt of the identifier; a second reader installed at an end portion of the passage to receive the identifier of the animal from the sensor inserted into or attached to the animal when the animal moves past the end portion or the second reader and to identify a second time of receipt of the identifier; and a management server that receives the identifier and the first time of receipt from the first reader, receives the identifier and the second time of receipt from the second reader, calculates the speed of movement of the animal matching the identifier, and predicting whether the animal matching the identifier is in estrus or not, based on the calculated speed of movement.

Aspects of the present invention relate to an apparatus and a method of determining when a cow may be in oestrus (in-heat), or when the cow is about to calve. The method comprises monitoring movement of the cow using a motion sensor or sensors attached to the cow. The method further comprises determining a mathematical function of the movement pattern of the cow based on the monitored movement of the cow over a period of time, and determining when the cow is in heat or about to calve by analysing and comparing the mathematical function to threshold values which are adjustable by a machine-learning self-adjusting algorithm.
