What is the function of feed additives in animal nutrition?

The function of feed additives in animal nutrition is primarily to improve feed efficiency. These additives can include a variety of substances such as vitamins, minerals, enzymes, probiotics, and flavor enhancers that are used to promote growth, improve the digestibility of feed, enhance nutrient absorption, and support overall health in animals. When feed efficiency is enhanced, animals are able to convert feed into body mass more effectively, which can lead to better growth rates and improved production outcomes in livestock. This ongoing optimization of feed utilization not only benefits individual producers but can also contribute to more sustainable agricultural practices by minimizing waste and lowering feed costs.

The other options fail to represent the beneficial roles that feed additives actually play. Instead of hindering animal health or reducing nutritional content, these substances are carefully formulated to support the health and well-being of animals. In addition, they do not reflect any notion of agricultural neglect; rather, they suggest a proactive approach towards enhancing performance and welfare in animal farming.
