The objective of this project was to design and construct a portable environmentally enriched wagon for a North American Porcupine with the intent for it to be used during educational presentations at the Omaha Henry Doorly Zoo and Aquarium. The wagon design was built using SolidWorks. A nine-step process was developed to build the wagon: (1) cut the boards to proper length and secure with corner braces (2) place border around primary and secondary platforms (3) add casters to primary boards and pegs to secondary board (4) connect U-brackets to board underside for dowels to fit (5) cut and add plastic base to boards (6) place cork tiles on secondary board (7) secure tree trunk and branches to primary board (8) secure hide next to tree (9) add woodchips to primary board. It took approximately 53 hours with two persons to construct the wagon and cost ~$63. In conclusion, the construction of the portable environmentally enriched wagon was successful. It was cost friendly and completed within the desired time frame.

Citrus fiber was tested in alternatively cured, all-pork bologna as a potential natural replacer of sodium tripolyphosphate (STPP). The STPP control, 0% STPP treatment and treatments containing various levels of citrus fiber (CF) (0.50%, 0.75%, 1.00%) all maintained acceptable quality throughout 98 days of refrigerated shelf-life. Results indicate that citrus fiber has potential to serve in a system with other binders as a natural alternative to phosphates in processed meat products, but not as a standalone single replacement source.

Selection for decreased RFI is controversial from a welfare standpoint, given that the genetic variation in RFI reflects the genetic variation in activity and response to stress. The objective of this experiment was to examine the behavioral metric correlations and growth performance of barrows divergently selected for residual feed intake (RFI) during a novel object test. Forty low-(LRFI, more feed efficient) and 40 high-RFI (HRFI, less feed efficient) barrows from the 8th generation Yorkshire selection lines were randomly selected. Barrows were evaluated in a Novel Object Test for zone crossing, zone 1 (defined as the mouth, nose, and/or face of the pig contact any part of zone 1), escape, freeze, urination and defecation frequencies and their effect on performance measures. Within the HRFI line, zone crossing frequency accounted for 10.9% of the variation in 10th-rib back fat at off test (r= 0.33; P = 0.04). Within the LRFI line, freeze frequency accounted for 13.7% of the variation in feed conversion ratio (r= 0.37; P = 0.03) and defecation frequency accounted for 11.6% of the variation in 10th-rib back fat at off test (r= 0.34; P = 0.05). Therefore, within the context of the ISU swine genetic selection program for improved lean accretion and feed efficiency, there were no negative behavioral metrics that determinately affected performance measures during the grow-finish period.

The objective of this study was to determine the effects of increasing inclusions of Diamond V Original XPC, a yeast fermentation product, on newly weaned beef steer performance and antioxidant defense. There was no effect of Original XPC on growth performance in the current study; however, blood measures indicated greater antioxidant capacity and lesser oxidative stress for steers fed XPC at 14 g/d. Further research is needed to better understand how oxidative stress impacts animal performance and health as well as the optimum supplementation dose of XPC for newly received beef cattle.

While the Iowa 4-H & FFA carcass contest cattle are not completely representative of all Iowa cattle, they can indicate trends for the Iowa cattle industry and represent the calves locally available for projects. With nearly 60% of these cattle receiving an $8/cwt premium, cattle feeders have the potential to improve net revenues by marketing cattle into a grid market.
