Dietary copper for dairy cows: how to get feeding levels right

This webinar is a past event - watch the recording.

Copper is an important trace element that supports many functions such as growth, fertility and immunity. The composition of the diet, in particular the level of copper antagonists (sulphur and molybdenum) and the impact on rumen pH, plays an important role in copper absorption.

 Join Liam Sinclair for a webinar looking at how dietary starch levels and copper antagonists impact the metabolism of copper. He will also provide recommendations to avoid over- or under-supplementation in diets with different concentrate levels and composition.

 The webinar will cover: 

• Dietary factors influencing copper availability in dairy cattle
• Effect of forage source on copper status
• Effect of dietary starch and concentrate level on copper status
• How to assess the status of your cows and practical means to avoid over- or under-feeding copper

Speaker biography

Liam Sinclair undertook a degree in Agriculture with Animal Science at Aberdeen University, before moving to Nottingham University where he completed a PhD on the interaction between dietary energy and protein supply on microbial protein synthesis in the rumen. He then moved to Harper Adams University as a lecturer, progressing to Professor of Animal Science in 2010. His research interests focus on dairy cows and include improving the health attributes of milk, increasing forage utilisation, improving mineral nutrition, and reducing the environmental impact of dairy cows. He was awarded the Sir John Hammond Prize in 2011 for his applied research in ruminant nutrition and ability to transfer research findings to industry, and in 2016 was elected as the President of the British Society of Animal Science.
