IceTag™ Devices: Feasibility for Measuring Activity and Postures in Gilts

The objectives of this project were 1) explore the feasibility of securing the IceTag™ device on sexually mature gilts, 2) determine effects of IceTag™ device on gilt behavior, and 3) compare IceTag™ data from gilts against the gold standard-behavioral data manually collected by a trained observer. Four individually housed bred gilts (~200kg) were used. The treatments were as...

Pig Age and Approachability Behavior to a Human Observer

The objective of this experiment was to determine if nursery pig age affected how many pigs touched and orientated to a human, or were classified as not-orientated during a human-animal interaction test using live human observation and digital image collection methodology. A complete randomized experimental design was utilized in this study where the pen of pigs was the...

Distance of Nursery Pig Snout and Tails from a Human Observer during an Approachability Test

The objective of this experiment was to determine the distance of nursery pigs snout and tails from a human observer when classified as touched, orientated to the human or s not-orientated during a human-animal interaction test using a digital image collection methodology. A complete randomized experimental design was utilized in this study where the pen of pigs was the...

Gilt and Barrow Approachability Behavior to a Human Observer

The objective of this experiment was to determine if nursery pig sex affected how many pigs touched and orientated to the human or were classified as not-orientated during a human-animal interaction test using a live human observation and a digital image collection methodology. A complete randomized experimental design was utilized in this study where the pen of pigs was the...

An Experimental Course: Animal Handling, Safety, and Well-Being

Students in the Department of Animal Science at Iowa State University are coming from increasingly diverse backgrounds, with little to no experience working with or handling various livestock species. In order to best accommodate these students, additional courses are being developed, one of which is Animal Science 190X: Animal Handling, Safety, and Well-Being. Through the course...

Behavioral Response to a Novel “X” Shape Target Stimuli in a Harbor Seal

The objective of this study was to provide an environmental enrichment device (shape target) to determine if it improved the Harbor Seal’s visibility in the underwater viewing windows when housed at the Blank Park Zoo. One male harbor seal (Phoca vitulina) 3-years of age weighing 39 kg was used. Testing occurred Saturday through Tuesday over 6 consecutive weeks between 1300 and...

The Micro-Environment in Trailers Transporting Market-Weight Pigs in the Midwest during Warm Weather

The objective of this pilot study was to determine how the micro-environment trailers transporting market-weight pigs’ change during different transport events in Iowa during warm weather. This study was conducted using 4 trailer loads carrying 680 mixed sex market weight (average 128 kg) pigs from commercial finishing facilities to a commercial processing plant all in Iowa. Data...

Independent Study 490H: The Effects of Environmental Enrichment during the Holding Period of Shelter Dogs on Rate of Adoption

The objective of this study was to determine the effects of providing dogs with environmental enrichment (EE) during the holding period on stereotypic behavior and if providing EE reduced the time to adoption. A total of 14 large dogs were selected for data analysis as they meet the following study inclusion criteria of being observed for 4 consecutive days. Dogs were assigned to...

Independent Study 490A: Do Play Groups for Shelter Dogs Reduce In-Kennel Arousal and Excitability Levels?

The objective of this study was to determine if 5-dog and 3-dog play groups had observable effects on-kennel arousal behavioral levels. This study was performed at the Animal Rescue League (ARL) of Iowa, located in Des Moines. A total of 36 dogs of mixed sex, breed, and age were observed. Two treatments were compared (1) 3-dog groups (n = 24) and (2) 5-dog groups (n = 12). All...
