Functional plant materials to boost growth performance, gastrointestinal health, antioxidation, and immunity in heat-stressed and necrotic enteritis challenged broiler chickens.

The annual heat-related losses incurred in the broiler sector alone were estimated at $51.8 million. Given current climate change realities and increasing poultry demand, it is safe to assume that these estimates would further increase. Similarly, subclinical necrotic enteritis (NE) reduced growth and productivity at an estimated cost of $6 billion annually in 2015. Prophylactic antibiotic administration is the primary means of prevention of NE. However, with regulations limiting antibiotic applications, there is an urgent need to develop effective new approaches to controlling infection by this and other pathogenic bacteria. Natural plant-derived feedstuffs (phytogenic substances) have been reported to have a great importance in nutrition and health. These plant materials contain phenolic substances and dietary fiber which are recognized as having health benefits and antimicrobial and antioxidative properties. This proposed study aims to investigate the ameliorative effect of some functional plant materials (seaweed, grape pomace and red osier dogwood products) on growth performance, gut morphology, gut microbiota, and biomarkers of oxidative stress in heat stressed and NE challenged broiler chickens. The study promises to increase profitability and sustainability for the poultry industry and offers an excellent opportunity to train 1 PhD, 1 PDF, and 1 MSc and equip them with
