Animal feed additives are a broad term used in a variety of nutritional products produced for livestock. Livestock farmers use a combination of nutrients to safely provide complete improvements to the health and functioning of their animals. Medicines or supplements that prevent or treat disease are regarded as drugs. They are highly regulated in animal feed products by the U.S. Food and Drug Administration (FDA) or similar institutions in other countries. Examples of the non-drug additives include yucca, aloe vera, yeast or yeast extract, kelp, glycosaminoglycans, probiotics, omega-3 fatty acids, bentonite, mineral oil, colour, and ethoxyquin, among others.

Meaning of Feed Additives

Feed additives are the products used to improve the number of animals by overcoming deficiencies, nutritional problems, and performance problems. Digestive problems, malnutrition, stressful pregnancies, and weakened bone formation can all be solved.

Over the last 3 decades, great strides have been made in understanding the body’s functions in pets, at the levels of organic matter, including the whole animal, its immune system, tissues, cells, and molecules.

Modern livestock and poultry production has achieved great success in the effective and economical production of high-quality and safe animal products and products. Livestock productivity can be increased by improving nutrient utilisation, health status, fertility, and production efficiency. Consumption of feed additives has been an important part of achieving successful livestock production.

Types of Feed Additives 

Dietary supplements are divided into five main groups:

1. Nutritional Supplements: These are supplements that provide specific nutrients like vitamins, amino acids, urea, and combinations of trace elements that are found to be deficient in the normal diet of the animal.
   
   2. Nutrition Supplements: These are supplements used to arouse the appetite of an animal to improve its diet. It usually takes the form of nutritious ingredients such as sweeteners, which also often change the appearance and aroma of the feed to make it look more attractive to the animal.

3. Anti-bacterial food ingredients: These ingredients are used to fight bacterial infections and infections. They usually do not bring additional value to the feed supply. They are also used to improve the efficiency of food consumption and food intake or to improve the health or body of an animal in some way.

4. Zootechnical Dietary Supplements: These are supplements that help increase the amount of nutritious animal feed. These nutrients enable the bodies of animals to take advantage of the nutritious content of their food. There are certain herbs such as thyme, oregano, and peppermint that help increase animal activity while positively affecting the animal’s digestive system.

5. Technical feed additives: These additives are intended for feed performance. Technical supplements help indirectly balance the management or purity of the feed. Reduce the corruption of the feed product. For example, preservatives protect food from degradation caused by microorganisms and antioxidants.

Feed Additives in Animal Nutrition

Here is the list of most common feed additives in animal nutrition:

Antioxidants: They prevent malnutrition caused by the breakdown of essential vitamins and fats. They also play a role in protecting against free radicals that can cause cancer, heart disease and more.

Enzymes: They are used to supplement digestive enzymes in an animal’s stomach to break down food. Enzymes also ensure that meat and egg production is improved.

Mould inhibitors and mycotoxin binders: Used to prevent fungal growth and to stop any harmful mould from being absorbed in the gut and blood, which can cause serious health problems.

Probiotics: Used to measure the level of bacteria in the stomach and to help digest food.

Antibiotics: They are used both for the prevention and treatment of diseases but also for rapid growth and development.

Hormones: Promote endochondral bone growth and long bone epiphysis.

Animal nutrition and productivity

Malnutrition reduces animal production. Plenty of literature on cooperation with the production of nutritious food shows that good feeding increases the milk of mammals.

• Nutrition increases the growth rate of meat-producing animals, providing more meat.

• Nutrition increases fertility efficiency:

1. High cyclicity.
2. Low age at the time of the first birth.
3. Low calf breeding season.
4. Highly productive health and high profitability for farmers.

Animal Feed and product safety and quality

The food chain quality and safety may be affected by the close interactions between feeders and bacteria found in food such as Escherichia coli, Salmonella, and Campylobacter.

• These germs can enter animal products through food.
• Mycotoxins, heavy metals, radionuclides, pesticides, dioxins, dibenzofuran, and other foodborne toxins are transferred to animal products that affect animal and human health and product safety.
• Animal feed safety has an impact on animal health, welfare, and production, as well as food security and the health of farmers.
• Safe food helps reduce production costs, maintain or increase food quality, and reduce food and food loss and waste.
• Infected food often leads to food being diverted or destroyed with severe economic losses to the livestock industry and a negative impact on food security.

Food is an important part of the food chain, so food production should be lower, in the same way as food production, in ensuring the quality of integrated food security systems.

Conclusion

In changing circumstances – achieving higher productivity, higher animal production, animal safety and quality, animal welfare, and health are increasingly needed. Increasing awareness and emphasis on animal welfare, as well as the environment, product safety, and quality, have been at the forefront of animal-based food production programs. Moreover, animal nutritionists are at a crossroads at which almost all sectors and activities of the livestock industry come together. Significant contributions can be made by veterinarians to produce adequate, safe, and nutritious food in a humane manner.
