Over 100 years ago, the TDN system was developed as a metric for estimating the energy value of feedstuffs, and it remains a commonly used tool in livestock nutrition today. Total Digestible Nutrients (TDN) represents the sum of all digestible nutrients within a feed, providing a valuable estimate of the energy an animal can derive from its diet.

According to animal nutrition experts, selecting nutrient-rich ingredients without considering their digestibility can lead to animal weight loss and deficiencies. Knowing what is the digestibility of a feed is therefore essential for maximizing nutrient uptake and ensuring animal welfare.

The total surface area available for nutrient absorption in the small intestine can be equivalent to a tennis court. This remarkable efficiency is central to understanding what is absorption in animal nutrition, the vital process that follows digestion and delivers essential building blocks to an animal's body.

Globally, feed additives are classified into several major categories by regulatory bodies like the European Food Safety Authority, with those categories encompassing numerous specific functional groups. Understanding what are the functional groups of feed additives is critical for producers aiming to optimize nutrient utilization, animal health, and overall farm profitability.

Globally, the animal feed industry is projected to reach over 1.3 billion metric tons in volume by 2025, driven by the increasing demand for animal-based protein. This growth is a testament to the essential role of specialized feeds in modern agriculture, highlighting the significant benefits of animal feed for producers, animals, and consumers.

In a study published in 2022, data from the Dog Aging Project indicated that dogs fed once daily, a form of restricted feeding, had lower odds of developing certain health conditions compared to those fed more frequently. This highlights a key debate in animal care: should animals be fed freely, or should their intake be controlled? These two primary feeding strategies, ad libitum and restricted feeding, have distinct approaches and outcomes for animal health and management.

According to the Food and Agriculture Organization (FAO), feed costs can account for up to 70% of an animal production operation's total expenses. Understanding what are the advantages of animal nutrition, therefore, directly impacts a farm's economic viability by influencing feed efficiency, health outcomes, and overall productivity.

A commercial Cornish Cross broiler can reach a market weight of 6 to 8 pounds in as little as 6 to 8 weeks, making it the highest-yield option for those wondering what chicken produces the most meat. However, its rapid growth comes with specific challenges and trade-offs that are important for any farmer or homesteader to consider.

Over 65% of the cost associated with raising livestock is attributed to feed, making energy a critical component of the diet. Understanding the energy content of feed, particularly the metric known as metabolizable energy (ME), is crucial for animal nutritionists and producers to formulate balanced, cost-effective diets that optimize animal performance and health.

With feed costs representing a significant portion of total livestock production costs, understanding what is the difference between feed additives and feed supplements is vital for producers. This distinction helps optimize nutrition, enhance performance, and address specific animal health needs efficiently.
