It is just as important for animals to have a well-balanced diet as it is for people. Therefore, animal nutritionists have made a career out of making sure that our farm animals get all of the necessary nutrients for them to grow and produce safe food. Highly nutritional diets are developed for each stage of an animal’s production cycle. For example calves are fed diets high in protein to help them develop strong bones, just like children. Later on, dairy cows that are ready to give birth to a calf will also have their diet tailored to meet their specific nutritional needs for both mother and calf.
Sometimes medications are applied to animals’ feed as this is the only way to medicate a large group of animals. These medications must meet the requirements listed in the “Compendium of Medicated Ingredients Brochure” (CMIB) , a document developed by the Canadian Food Inspection Agency. This Compendium lists only those medicating ingredients allowed by Canadian regulation to be added to livestock feed. This document lists the species of livestock, the level of medication, the directions for feeding and the purpose for which each medicating ingredient may legally be used, as well as the brand of each medicating ingredient that is approved for use in Canada.
The Animal Nutrition Association of Canada (ANAC) represents the companies that manufacture livestock feed in Canada. They have developed a program that applies the HACCP-based principles developed for human food to animal feed. Their FeedAssure program is designed to ensure that animal feed contains only those ingredients that should be present are in fact in the feed.
