Trish Lewis – Maximising Digestible Protein from Silage

After graduating with an Honours degree in Agriculture from the University of Nottingham, Trish began her career in the UK dairy and animal feed industries. In 1997, she immigrated to New Zealand and joined Nutritech as a nutritionist, marking the beginning of her long-standing contribution to the country’s agricultural sector.
Trish later worked with Cundy Technical Services, before establishing herself as an independent nutrition consultant with a focus on dairy systems in the Northland region. For the past nine years, she has returned to Nutritech in the role of forage and silage consultant, providing farmers with expert advice on improving silage quality and optimising the use of homegrown feed.
With extensive practical experience and technical knowledge across all aspects of silage—from harvesting through to feeding—Trish is a respected voice in the industry. She has regularly presented at conferences and farmer workshops, and has contributed technical articles to agricultural publications on silage and ruminant nutrition.
Trish is a founding member and now a Lifetime Member of the New Zealand Association of Ruminant Nutritionists (NZARN), reflecting her enduring commitment to advancing animal nutrition in New Zealand.
