The present invention provides PCR primers with which sexing of bovine embryos can be easily attained and provides a practical, rapid and reliable method for determining the sex of bovine embryos using these primers. The methods for determining the sex of the bovine embryos are characterized by discriminating PCR products which are obtained by amplifying specific DNA sequences by PCR with pairs of male-specific and gender-neutral primers. These primers are derived from DNAs which specifically hybridize to the bovine male genome and from DNAs which gender-neutrally hybridize to both bovine male and female genomes.

A carcass tilting device equipped in a spinal cord removing apparatus for suctioning and removing spinal cord from spinal cavity of a carcass of slaughtered cattle, to facilitate removing spinal cord from the carcass suspended with its head down in a vertically narrow space, comprises a support column 21, a tilting member 23 pivotally mounted on the support column 21 and having a contact portion 25a with which the carcass makes contact, and a second cylinder 29 configured to cause the tilting member 23 to pivot to be tilted with respect to a vertical direction such that a lower end of the tilting member is raised. The tilting member 23 has an inner member 24 and an outer member 25 which are displaceable in the longitudinal direction from a position where the members 24 and 25 overlap each other, thereby causing the tilting member 23 to entirely extend.

The present invention relates to a peptide having an amino acid sequence of Val-Val-Tyr-Pro as well as an agent for inhibiting elevation of triglyceride levels in blood, a food for specified health use (the so-called physiologically functional food) and a feed comprising the above peptide as an active component. According to the present invention, a peptide inhibiting elevation of triglyceride levels in blood as well as an agent for inhibiting elevation of triglyceride levels in blood, a physiologically functional food and a feed, all comprising the peptide as an active component are obtained. With these products of the invention, it becomes possible to prevent or treat obesity and hyperlipemia of human and animals as well as circulatory system diseases such as hypertension and arteriosclerosis associated therewith. Furthermore, the materials of the invention make it possible to improve the meat quality of livestock and hatchery fish.
摘要:
A foreign matter removal device 10 preliminary cleans the work 50 in a bucket 12 housed in an input tank 15, then further cleans the work 50 in buckets 13, 14 housed in cleaning tanks 16, 17 by agitating cleaning liquid while inverting the buckets to transfer the work to a subsequent bucket. Particularly, the bottom of the cleaning tank is formed such that the nearer to a center of the bottom, the deeper the bottom becomes. The cleaning liquid overflowing from the cleaning tanks are stored in auxiliary tanks 22, 23. First and second ejection units 29a, 29b are arranged at different heights in the cleaning tank to generate a circulating flow in the cleaning liquid.
