What: A "performance" angus breeding bull on auction in Northern California will become a source of revenue for students at UC Davis. Proceeds from this bull's sale will go to the campuswide Students First fund-raising campaign and will support animal science students. The bull has been donated by rancher Bill Borror and it will be auctioned at his ranch in Gerber. UC Davis is doing all it can to ease the financial burdens of its students. Students First aims to increase private financial support for UC Davis students and their families. The campus goal is to raise more than $15 million by Dec. 31, 1995. The bull to be auctioned weighs about 1,400 pounds and is expected to be sold for at least $4,000. More than 200 ranchers from the western United States will attend Borror's well-known auction. When: Friday, Sept. 23, at noon Where: From Redding, proceed south on Highway 99 and exit at Tehema Avenue. Travel east on Tehema Avenue for 1 mile and enter the Tehema Angus Ranch property. Visuals: In addition to this particular bull, there will be a number of other bulls auctioned. A ranch lunch will also be provided for those who attend. Background: An alumnus of UC Davis, Borror is donating the proceeds of this bull to the campus animal science department for supporting joint student/faculty research projects. Students knowledgeable in research methods gain analytical abilities that inevitably help the animal industry, according to Borror. The department averages 380 undergraduate students, notes James H. Meyer, chancellor emeritus and professor of animal science. In addition, he says, the animal science department has 85 graduate students in two master's programs and several Ph.D. programs in specific animal-related disciplines such as genetics and nutrition.
