Study looks at zinc oxide in growth, health of pigs

Jan 09, 2023

A Kansas State University swine nutrition student is conducting research that focuses on potential alternatives to zinc oxide, a common ingredient in the diets of weaned pigs, in a project he says may contribute to the swine industry’s goal of improving the efficiency of pork production and animal welfare.

“Pharmacological levels of zinc from zinc oxide have been shown to improve growth performance and health status of the newly weaned pig,” graduate student Ethan Stas said in a university news release. “However, there are growing concerns with the use of pharmacological levels of zinc in swine diets because of environmental concerns.”

Stas — who is working with feed ingredients with an acid binding capacity at a pH level of 4 (known as ABC-4) — noted that the European Union has already banned the use of pharmacological levels of zinc and said that North America may follow a similar path

T.K. Cheung Lecture in Animal Science: "Using science to assess and improve the welfare of dairy cattle"

Dan Weary is a Professor at the University of British Columbia. Dan did his BSc and MSc at McGill and Doctorate at Oxford before co-founding UBC’s Animal Welfare Program where he now co-directs this active research group. His research focuses on understanding the perspectives of animals and applying these insights to develop methods of assessing animal welfare and improving the lives of animals. His work has helped drive changes in practices (including the adoption of higher milk rations for calves and pain management for disbudding) and housing methods (including the adoption of social housing for pre-weaned calves). He also studies cow comfort and lameness, social interactions among cows, and interactions between cows, human handlers and technologies like automated millking systems that are increasingly used on farms. His presentation will outline key questions in cattle welfare, highlight recent UBC research addressing them, and showcase innovative methods for improving the lives of cattle and their caretakers.
