Rosalina Angel

Dr. Roselina Angel
Associate Professor, Animal and Avian Science
Extension Poultry Specialist

The work done in Dr.  Angel's lab melds applied and basic nutrition. The main focus is on maximizing nutrient availability from diets with the goal of reducing environmental impact as well as improving production efficiency and costs of production. The tools used for this work go from the very basic (epigenetics or nutritional imprinting, gene expression of transporters as well as specific genes that can be associated with changes seen, measures of nutrient absorption as well as intestinal enzyme, and gastrointestinal tract morphological changes) to the very applied (demonstration trials with industry to validate tools developed in the lab. 

Extensive work has been done and continues on minimizing the impact of poultry production on the environment, primarily as related to phosphorus and nitrogen. Work with phosphorus has focused on understanding requirements, improving absorption through management and diet (calcium/phosphorus ratios, use of enzymes and other feed additives) and implementation of new tools under commercial conditions. Work with nitrogen has focused on diet changes as well as post excretion changes to minimize nitrogen excretion and nitrogenous emissions to air.
