I am an MSc. thesis student studying swine nutrition specifically in trace mineral digestibility in weanling pigs, under the supervision of Dr. Ming Z. Fan (http://animalbiosciences.uoguelph.ca/abscpeople/mfan). When I was a child, I have always been passionate about taking care of animals, including dogs, rabbits, crabs, frogs, hamsters, etc., and had a strong relationship with them. I was always eager to learn more about animal nutrition, behaviors and other knowledge about them. As such, I have cultivated a passion for animals because I regard them as our best friends and want to improve their wellbeing through nutritional diet.

My research mainly focuses on intestinal responses and the determination of true digestibility and the endogenous losses of trace minerals (specifically copper, iron, manganese, zinc, and selenium) in weanling pigs by a mathematical method, regression analysis. Trace mineral, not only in human nutrition but in animal feeding, is an area with scarce information and understanding of bioavailability leading to oversupplying in food and feed, which could potentially cause extra cost as well as environmental pollution. In my research, I am using a simple linear regression model, based on the relationship between total tract apparent digestible trace minerals and total dietary trace mineral intake of the weanling pigs, to estimate the true trace mineral digestibility which is recommended to use to swine diet formulation and the endogenous trace mineral losses. Compared to other methods, the regression model is much cheaper, more accurate, more reliable, and convincible than other methods measuring true nutrient digestibility. Also, the growth performances, the apparent ileal and total tract dry matter digestibility, gut permeability and jejunal alkaline phosphatase activity kinetics were also conducted to investigate the intestinal responses of different gradient levels trace minerals in experimental diets in weanling pigs. I hope this research is able to have a tremendous contribution in swine diet formulation, reducing feed costs as well as detrimental impacts of excessive manure heavy trace minerals on the environment. For the future, I am still hesitating about pursuing a career or a higher degree in this area after I graduate, hopefully, I can figure it out as soon as possible!

During my free time, I love to workout, play basketball, walk my dog and watch funny YouTube videos! By the way, I am a big fan of the Raptors!
