Analysis of food for animals

Animal feed represents the most important cost in milk production, therefore the control of the food produced as well as those included from external origin are essential to control to ensure a supply in agreement with the production levels, quality and safety required.

The objective is to know the nutritional value and microbiological quality of food supplied to livestock on the farm.
