Raised on a sheep and pig farm, Russell Jennings has over 30 years’ experience in the animal nutrition and feed industry with a career spanning sales leadership, product innovation and strategic development.

He began in 1989 as a Sales Representative with Agway Milling, later founding Agri-Yield in 1991 to supply feed and train on-farm sales teams. He held senior roles at Celtic Sea Minerals and later Vistavet, where he supported the shift from in-feed antibiotics to sustainable nutritional solutions.

From 1996 to 2006, Russell worked closely with Lesaffre Feed Additives (now Phileo), first through Vistavet and later AB Vista, who were Phileo’s distributor for the UK and Ireland. In 2009 Phileo UK & Ireland was set up, where Russell became Sales Director and shareholder. He was appointed Managing Director in 2014.
