Compuler simulalion models for growth and developmeni of economically important 

 crops and weeds. 



Objective 3. Animal Productivity 



• Means to reduce mortality and other losses from disease and parasites, improve — at 

 the molecular level — genetic resistance to diseases and parasites, use biologically 

 based control of parasites, control zoonotic bacteria and parasites In the live animal, 

 increase the genetic capacity of animals for greater production, and evaluate 

 behavioral, physiological, and productivity indicators of animal well-being. 



• Elucidation of physiological processes involved in feed intake and metabolism and 

 mechanisms by which chemical and physical composition of feed limits nutrient 

 availability. 



• Technology for nondestructive repeated measurements of body composition. 



• Means to use animal wastes and means to reduce waste contamination of surface and 

 ground water. 



Objective 4. Commodity Conversion and Delivery 



• Means to prevent or eliminate foodbome microorganisms In animal products, prevent 

 mycotoxins in food and feed products, elimmate insect and disease trade barriers 

 limiting agricultural exports, meet commodity quality market requirements (physical, 

 sanitary, performance), and extend shelf life with sensory quality retention. 



• Methods for rapid, objective analysis of marketing safety and quality characteristics. 



• Technologies for conversion of agricultural commodities to value-added industrial 

 products, alternative fuels, and new fiber, leather, feed, and food products; process 

 treatments to enhance food safety, minimize residues or additives, and retain quality; 

 and altemalive environmentally benign processes and products. 



Objective 5. Human Nutrition and WellBeing 



Methods to determine composition of commonly consumed foods for several nutrients 

 and phyiogenic components and to change food production and processing systems to 

 improve food nutritional quality. 



Elucidation of role of dietary components in weight maintenance and risk of chronic 

 diseases, adequate and safe ranges of nutrient and calorie intake, and molecular and 

 cellular basis of human nutrition.
