The invention features a single tool for collecting a known volume of a fluid biological sample from an animal, such as a human or small mammal, for mixing the sample with a predetermined amount of a reagent or a diluent, physically separate components of the sample, for storing the sample in a secure and stable fashion, and for then recovering some or all of the sample in a condition suitable for performing a diagnostic assay. The tool can be equipped with an optional means of recording or displaying information about the sample, such as a tag, a bar code, or a surface indicator that identifies, e.g., the date, animal number, and any additional information necessary. A second bar coded label to remove and attaché to the cage shall be provided. The cage/blood-sample can be correlated if needed at a later date.

A noninvasive photoplethysmographic sensor platform for mobile animals such as small rodents, namely rats and mice is useful such as in a laboratory research environment. The noninvasive photoplethysmographic sensor platform may be a collar which provides an easily affixed, adjustable attachment mechanism that encircles the animal, such as the neck. The neck of the animal provides several particular advantages as a sensor mounting platform for photoplethysmographic sensors. For pulse oximetry, the neck location will provide significant blood flow under all conditions. For small mammals, such as rats and mice, transmittance pulse oximetry through the neck of the subject remains possible. The neck mounted collar also offers inherent bite resistance to the sensor platform.

The current invention is based upon administration of a probiotic, B. Lactis NCC2818 to healthy young mammals during the critical weaning period (in infants this period is usually from about 3 months to about 12, 18 or 24 months old), so as to accelerate the young mammal's adaptation to new food. The effectiveness of the invention is evidenced herein by morphological and immunological changes observed in a piglet animal model of weaning. Thus, administration of the probiotic according to the invention had a prophylactic effect, preventing the severe discomfort and pathological states associated with the introduction to novel foods during the weaning period.

The present invention relates to methods and compositions for inhibiting, treating, and preventing dental diseases in human and non-human animals, particularly domesticated companion animals. More particularly, the present invention relates to the unexpected discovery that the combination of micron-sized particulate bioactive glass and a topical bisphosphonate yields a composition that is capable of treating and/or preventing dental problems such as periodontal disease, tooth decay and tooth resorption in animals, particularly small mammals such as cats.

Described herein are systems and methods for efficient and accurate, automated detection of a region of interest interior to the ribcage from an in vivo mammalian image. It is found that efficient, automated identification of the region of interest interior to the ribcage can be achieved by the use of both a bone distance mask and a surface distance mask. The technique solves the problem of accurate and fast identification of the region of interest for a wide range of sizes and shapes of mammals, e.g., small mammals such as mice.

Pest control in an enclosed area, such as a room of a building, by positioning an ozone producing device in an area to be treated. Ozone generating ultraviolet lamps emit ozone around the entire perimeter of the device, generating ozone from the atmosphere within the enclosed area. A concentration of ozone in the area is measured by a sensor. Production of ozone by the ozone generating ultraviolet lamps is terminated upon the ozone concentration reaching a predetermined concentration of ozone or by time of exposure. Pests that are subject to treatment include invertebrates, such as insects and arachnids, or small mammals, such as mice and rats.

The invention relates to a method for improving animal semen quality by the use of a chestnut flower ethyl acetate extract. The male ablactation mammals are daily supplemented with the chestnut flowerethyl acetate extract through a gavage mode or a mode of adding into a feed: acceptable daily intake of small male mammals is 0.01-5 mg/kg (weight), and acceptable daily intake of middle-sized male mammals is 0.1-10 mg/kg (feed). The chestnut flower ethyl acetate extract is a freeze-dried powder after ultrasonic extraction and further hyperfiltration. After ultrasonic extraction of the chestnut flower ethyl acetate extract and further hyperfiltration, male mammals are supplemented with the chestnut flower ethyl acetate extract so as to remarkably improve animal semen quality, and the supplementary feeding time starts after ablactation of the male mammals. The technical scheme helps male mammals to better establish a reproductive system, fully tap genetic potential of male animals and broaden using range of the chestnut flower ethyl acetate extract.
