D.H. Owings Summer Session II 2009 Sarah Laredo PSC113 LAB PIGLETS: ONTOGENY OF NURSING AND ITS SOCIAL CONTEXT Rules regarding access to the Swine Facility. 1. You may not enter the facility if you, or your clothes or shoes have had contact with swine or other food mammals (cattle, sheep) within the previous 24 hours. 2. You must apply shoe covers before entering the facility (these will be provided). 3. You should wash or disinfect your hands before leaving the Swine Facility . You may need to change clothes after this lab; 2 hours in the swine barn does not aromatic clothing make. You may also want to wear a cap or other head covering to minimize absorption of pig odor by your hair. (But, it’s a new facility, so this may not be as big a problem as in the old barn.) Please also note that we will observe piglets for two weeks. Note that you will be car-pooling out to the swine facility. Driving instructions : head west on Hutchison, across Hwy. 113, as though you’re going to Rd. 98 and the primate center. Turn left on Hopkins Rd., the fifth road (including dirt roads) that goes off to the left after crossing Hwy. 113 (it’s also the last road before Rd. 98 & the primate center). There may not be a sign identifying Hopkins Rd., but it probably says that Bee Biology is back there, too, and it’s the 2 nd olive-tree lined road. Continue back Hopkins, and take the 2 nd left onto Stralock Rd. The swine barn is just a couple of hundred feet down Stralock, on the left. Pull into the parking lot on the near (Hopkins Rd.) side of the barn – no parking permits are needed. Come on around to the front (Stralock Rd.) side of the barn, and wait outside until the TA arrives to provide further instruction. Restrooms are accessible from the outside if you need them. This exercise will provide the opportunity to record data on the occurrence and ontogeny of parent-offspring and peer-peer interactions. It also has the potential to reveal the phenomenon of social contagion, the active role of young in extracting parenting, and how even closely related individuals such as full siblings need to deal with conflicts of interest.
