Abstract: A conventional pig estrus measuring device can only measure the weight of a pig by measuring the weight of the pig using one or two load cells, and the estrus of a pig cannot be known thereby. To solve such a problem, an automatic breeding device according to the present invention comprises an entrance door, a weight measuring part, a feeding part, and an exit door part. The weight measuring part comprises: a top plate composed of a rectangular top plate frame and a top plate wire mesh; and load cells placed in the middle of the long side of the top plate and at the four corners of the top plate, at the lower part of the top plate. The estrus of a pig is determined from a change pattern of the weight of the pig measured by the six load cells and generated when the pig enters the automatic breeding device. When it is determined that the pig is in estrus from the change in the weight of the pig, pheromone is generated by driving a pheromone scent generator provided at the lower part of the front part of the weight measuring unit where the pig′s head is located, so that it is possible to accurately inspect the estrus of the pig. Also, the movement of a pig after the generation of the pheromone is measured by the six load cells to determine whether there is a change in the movement of the pig. According to the structure of the present invention, a means for determining whether a pig is in estrus is provided, and by using the pheromone scent of a male pig for more accurate confirmation of estrus, the estrus can be more reliably detected earlier.

Title: Fabric softener composition with antimicrobial effect
Inventor: PARK YONG SOON
IPC: C11D3/00
Filed: 2019-08-14
Abstract: The present invention relates to a fabric softener composition, and more particularly, to a fabric softener composition having antibacterial and deodorant effects. According to the present invention, the fabric softener composition includes an eucalyptus extract and a grapefruit seed extract as active ingredients, and includes a cationic surfactant, a nonionic surfactant, and water. The fact that the eucalyptus extract and the grapefruit seed extract have a bactericidal effect against various microorganisms including germs such as bacteria and viruses has been known before the present invention. However, it has not been expected to provide a fabric softener composition in which such natural extracts are mixed with other ingredients of the fabric softener composition at a concentration within a range that is harmless to a human body to exhibit a sterilizing or antibacterial effect while maintaining a sufficient fabric softening effect without affecting other components of a fabric softener. According to the present invention, each of the eucalyptus extract and the grapefruit seed extract is preferably 0.1 to 10 wt% of a total weight of the composition. When each of the eucalyptus extract and the grapefruit seed extract is less than or equal to 0.1 wt%, antibacterial and sterilizing effects are weakened, and when each of the eucalyptus extract and the grapefruit seed extract is greater than or equal to 10 wt%, a fabric softening effect is reduced.
