Mineral Nutrition In Broilers: Where Are We At?, Rick Kleyn, Mariana Ciacciariello Aug 2021

Mineral Nutrition In Broilers: Where Are We At?, Rick Kleyn, Mariana Ciacciariello

Proceedings of the Arkansas Nutrition Conference

Mineral nutrition remains an essential consideration for broiler nutritionists. The complex interactions between different minerals sources, other ingredients, and the broiler itself, coupled with their relatively low costs, have led to the current status of elevated levels of minerals in broiler diets. New perspectives on sustainability have brought about a rethink of the way we formulate practical diets. There are considerable opportunities for reducing macro minerals such as calcium and phosphorus, particularly for older birds. Our understanding of attaining an ideal dietary cation-anion balance is confused by the lack of clarity in measuring the balance and the bird’s ability to …

Measuring Palatability As A Linear Combination Of Nutrient Levels In Food Items, Jeffrey S. Young Aug 2021

Measuring Palatability As A Linear Combination Of Nutrient Levels In Food Items, Jeffrey S. Young

Faculty & Staff Research and Creative Activity

It well known that palatability and nutritional quality of foods and/or diets are viewed as being in tension with one another. While there exist multiple measures of healthiness, there are no such measures for tastiness. This gap limits the degree to which researchers can investigate this tension and its implications for dietary behavior and hence public health and nutrition policy. The scope of future work concerning the dietary behavior of Americans would expand greatly if researchers better understood consumers’ willingness to eat certain foods, which matters as much as recommending those foods for them to eat in the first place. …

Data From: Yellow Air Day Advisory Study, Arthur J. Caplan Aug 2021

Data From: Yellow Air Day Advisory Study, Arthur J. Caplan

Browse all Datasets

Using a dataset consisting of daily vehicle trips, PM2.5 concentrations, along with a host of climactic control variables, we test the hypothesis that “yellow air day” advisories provided by the Utah Division of Air Quality resulted in subsequent reductions in vehicle trips taken during northern Utah’s winter-inversion seasons in the early 2000s. Winter inversions occur in northern Utah when climactic conditions are such that PM2.5 concentrations (derived mainly from vehicle emissions) become trapped in the lower atmosphere, leading to unhealthy air quality (concentrations of at least 35 µg/m3) over a span of what are called “red air days”. When concentrations …
