Why are feed additives used in animal rations?

Feed additives are incorporated into animal rations for several important reasons, and one of the primary purposes is to improve animal health. These additives can encompass a wide range of substances, including vitamins, minerals, probiotics, and other supplements that enhance the nutritional value of feed and ensure that animals receive the essential nutrients necessary for their growth, reproduction, and overall well-being.

Improving animal health through feed additives can also lead to better performance, such as increased weight gain, improved feed efficiency, and enhanced immune function. This is particularly crucial in large-scale animal production, where maintaining herd health is vital for profitability and sustainability.

In contrast to the other choices, while some feed additives might have indirect effects related to feed intake, carcass composition, or shelf life, the primary aim of many commonly used additives is indeed to contribute directly to the health and robustness of the animals consuming them. This focus on health reinforces productivity and welfare in livestock management.
