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

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.

Liam Sinclair looks at how dietary starch levels and copper antagonists impact the metabolism of copper. He also gives recommendations to avoid over- or under-supplementation in diets with different concentrate levels and composition.

The webinar covers:
• 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
