The Importance of Optimum Vitamin Nutrition

The vital importance of vitamins for the health of humans and animals was established in the early and mid-20th century, with the main target being to identify the minimum amounts required to avoid deficiency symptoms.

Published 20 years ago

This research was carried out around the middle of the 20th century by a number of highly respected organisations and the results published around 20 years ago.

Times move on

In the meantime, our food-producing animals and the way they are reared have changed fundamentally in terms of their productivity.

The last two decades have also seen significant changes in societal attitudes, including a greater interest by consumers in how their food is produced.

Recognised Experts update Knowledge

To help update our knowledge, DSM Nutritional Products has invited recognised experts to review the vitamin requirements of farm livestock for maintenance, growth, breeding and production. They have also addressed aspects of animal health and welfare, as well as product (meat, milk egg) quality, where appropriate.

Hugely useful reference

This new book is a fantastic reference for everyone who works with aminal and animal nutrition, from vets to farmers to researchers.
