A total of 84 sows (PIC 1050) and their litters were used to determine the effects of supplementing maternal diet with vitamin D3 on sow and pig performance, serum 25-hydroxyvitamin D3 (25(OH)D3), milk vitamin D3, neonatal bone mineralization, and neonatal tissue vitamin D3. After breeding, sows were randomly assigned to 1 of 3 dietary vitamin D3 treatments(More)
SUMMARY: We examined whether college‐ age video game players and musicians are better than controls at implicit sequence learning in the Alternating Serial Reaction Time Task. People learn to use subtle sequence regularities to respond more accurately and quickly to predictable versus non‐predictable events. Although previous studies have shown experts'(More)

In 2 experiments, 530 pigs were used to evaluate the effects of adding commercial enzymes to diets containing dried distillers grains with solubles (DDGS) on pig growth performance. In the first experiment, 180 pigs (9.0 kg initial BW) were fed a corn-soybean meal-based control diet, a diet containing 30% corn DDGS, or the 30% DDGS diet with 0.05% of enzyme(More)
Eye movement deficiencies are inherent with age and tend to increase in distracting visual fields, in the useful field of view (UFoV), and when information is located in the periphery. Despite well-known age-related differences in eye movement, there has been limited empirical study into how older adults look at Web sites. The study of eye movement during(More)
Two experiments were conducted to evaluate the effect of nursery diet sources, porcine circovirustype 2 (PCV2) and Mycoplasma hyopneumoniae (M. hyo) vaccines, and vaccination timing on pig (Sus scrofa) performance. In Exp. 1, a total of 400 pigs (5.6 BW, 1.03 kg SD) were used in a 20-d study. Treatments were arranged in a 4 × 2 factorial in a blocked design(More)
In a usability study on a portion of the Census Bureau Web site, we assess how people of different ages search for specific information by evaluating performance and strategy differences between age groups. We collected us-ability metrics of accuracy and efficiency, including mouse click data. Eye-tracking data were also collected including eye-movement(More)
