Extension Interests
My extension responsibilities are related to broiler nutrition and management, and nutrient and waste management. Educational nutrition programs include the North Carolina Turkey Industry Days and Poultry Supervisors’ Short Course, the Carolina Poultry Nutrition Conference and short courses, workshops, and seminars held periodically throughout the state and abroad. Topics include broiler nutrition and feeding, broiler health and management, effects of broiler breeders on broiler performance, efficacy of feed additives (coccidiostats, antibiotics, probiotics, prebiotics, symbiotics, amino acids, vitamins, and minerals, etc.), and nutritional factors that affect enteric health and meat quality. An emphasis is made on broiler house air quality issues.
Research Interests
-
To understand mechanisms of nitrogen and amino acid utilization; to improve efficacy of low crude protein diets in broiler chickens and minimize nitrogen environmental impact, including air emissions.
-
To develop computerized growth models to be used as tools to determine economical optimal management practices and feeding programs.
-
To evaluate feed additives, feedstuffs, feed processing methods, and their effects on intestinal pathobiology, specific immunity against Eimeria spp., gut microbiota dynamics, and microbial uricase activity.
-
To estimate the optimum dietary electrolyte balance and mineral requirements for optimum performance.
-
To improve the understanding of avian bone development and leg disorders in broilers and turkeys.
Educational Programs Under My Coordination
The NC Broiler Supervisors' Short Course
The NCSU International Course on Poultry Production
The Carolina Poultry Nutrition Conference, Poultry Nutritionists Round Tables; workshops and seminars held periodically throughout the state and abroad.
Topics include:
Broiler nutrition and feeding, and broiler health and management.
Effects of broiler breeder management and nutrition on broiler performance.
Effects of hatchery and incubation management on broiler performance, bone development and welfare.
Evaluation of efficacy of feed additives and nutritional factors that affect enteric health and meat quality. This includes evaluation of coccidiostats, antibiotics, probiotics, prebiotics, symbiotics, crystalline amino acids, vitamins, trace minerals, and vaccines against Eimeria spp.
Technologies to improve broiler house air quality and reduce gas emissions.
Presentations
Alternative Feed Additives to Replace Antibiotics and Ionophores in Poultry Diet
Methods to Minimize Environmental Impact Due to Nitrogen Excretion from Poultry
Practical Applications of Modeling and Decision-Making Analyses in Poultry Production
