What are the main functions of feed additives?
Feed additives are substances that protect the nutritional value and palatability of poultry feed, as well as enhance the immunity of poultry. Currently, the number of additives added to feed is increasing, which strengthens the appetite of livestock and ensures safe growth. So, what is the role of feed additives? Let's take a look!
1. Improve feed palatability, which has a positive significance for enhancing feed palatability and promoting livestock consumption. The use of feed additives can not only improve the palatability of feed but also achieve good feeding results.
2. To improve feed processing performance, nearly two-thirds of feed mills in the United States use various forms of adhesives when producing pellet feed to reduce dust, enhance feed processing performance, and increase feed production capacity. Many nutrients contained in feed, such as vitamins and unsaturated fatty acids, are prone to oxidation failure or deterioration. Almost all countries with developed feed industries use antioxidants and antifungal agents in production to reduce nutrient loss during feed processing and storage. Experiments have shown that the loss of carotene in grass powder treated with antioxidants is reduced by 25% to 50% compared to grass powder without antioxidants after six months. Therefore, using preservatives such as antifungal agents and antioxidants can prevent nutrient loss in feed and avoid waste.
3. Promote the growth and development of livestock. Feed additives have the effects of disease prevention and health care, as well as promoting livestock growth. Their usage has rapidly increased in recent decades, playing a positive role in improving livestock production performance. In addition to antibiotics and synthetic antibacterial agents, many new growth promoters such as probiotics, oligosaccharides, and organic acids have also been applied in livestock production.
4. Improve the quality of livestock products. With the improvement of people's living standards, consumers' demands for the quality of livestock products are increasing. The quality and appearance of livestock products can be improved through feed additives, extending the shelf life and selling price of livestock products.
5. Rational allocation of feed resources. Feed is composed of various feed ingredients. After using feed additives, it is possible to utilize underutilized or insufficiently utilized feed resources to produce nutritionally complete feed, thereby expanding the utilization of feed resources that are used in a single state or limited use, and reducing cooperative feed costs. Especially for some feed ingredients that contain anti-nutritional factors, single use can be detrimental to the health of livestock and may endanger the health of the environment or humans. However, by using corresponding additives in combination, these feed resources can be fully utilized, achieving higher social, ecological, and economic benefits.
In summary, the role of feed additives in livestock production is multifaceted, permeating almost every aspect of modern animal husbandry production.
