Dr. Elijah Kiarie joined the University of Guelph as an assistant professor in 2016 and was appointed as the Mcintosh Family Professor in poultry nutrition.

Dr. Elijah Kiarie’s interest in farm animals originated from growing up on a small family farm in Kenya. He described obtaining a bachelor’s degree in agriculture, majoring in animal science, as the catalyst for fueling his interest in animal nutrition.

Motivated to gain the necessary skills to improve feed quality and utilization of byproducts, he pursued a master’s degree in animal szcience (nutrition). He remained compelled to advance his understanding of nutrition and moved to Canada to pursue a PhD in monogastric nutrition at the University of Manitoba, where he was awarded a doctor of philosophy degree in 2008.

Having completed a Post-Doctoral Fellowship, Kiarie spent several years working as a research scientist in the swine and poultry nutrition industry and has made notable contributions in advancing the understanding of the application of exogenous feed enzymes to improve nutrient utilization and modulate gut health, while reducing feed costs and environmental impact. This research resulted in patent applications and invention disclosures related to the development of feed technologies for improving health and productivity of farm animals in addition to many significant scientific publications contributing to this area of research.


Kiarie joined the University of Guelph as an assistant professor in 2016 and was appointed as the Mcintosh Family Professor in poultry nutrition. He is concentrating on two areas of research at this point in his career; the gastrointestinal tract as a potential rate-limiting factor in survival and productivity of poultry and ways to manipulate perinatal nutrition for stronger skeletal growth to improve productivity, skeletal integrity and welfare.

A rising star
Kiarie’s ongoing research project entitled Investigating optimal feed structure for promoting pullet gut and skeletal development for enhanced layers productivity is in part supported by CPRC. This project aims to investigate use of dietary insoluble fiber to alter diet structure in developing pullets with the objective of promoting gut and skeletal health and productivity in laying hens. The ongoing experiments will determine the effects of the addition of fiber on: gut health and performance, and skeletal development and performance in the pullet stage through to the end of the laying cycle. A recent finding of this research shows that enhancing the digestive capacity through feed additives and processing plays an integral role in improved utilization of nutrients. Additionally, distinct feed additives and functional factors can complement each other through different modes of action on the gut. Kiarie will continue research to elucidate whether this is an additive, antagonistic or synergistic relationship.

CPRC, its board of directors and member organizations would like to acknowledge Kiarie as a ‘Rising Star’. His research responds directly to the needs of the scientific and poultry industry and addresses industry and CPRC research priorities. We anticipate that the outcomes of this research will benefit the poultry industry.

CPRC, its board of directors and member organizations are committed to supporting and enhancing Canada’s poultry sector through research and related activities.
