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 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.
