The Linders Feed Chart is a valuable tool for animal nutritionists, providing essential guidance on optimal feed rations for various species and life stages. It considers a range of parameters and factors, making it a comprehensive resource for ensuring the health and well-being of livestock.
Developed by Dr. David Linders, the chart has gained widespread recognition for its accuracy and reliability. It is commonly used in the formulation of feed rations for cattle, horses, sheep, goats, and poultry, among other animals.

Overview of Linders Feed Chart
The Linders Feed Chart is a valuable tool in the field of animal nutrition, providing guidance on the nutritional requirements of various livestock species and production stages.
The chart considers factors such as animal species, age, weight, production level, and environmental conditions to determine the optimal feed intake and nutrient composition.
Parameters and Factors Considered in the Chart, Linders feed chart
- Animal species: Different species have varying nutritional needs based on their physiology and metabolism.
- Age: Nutritional requirements change as animals grow and develop, influencing feed intake and nutrient composition.
- Weight: Body weight is a key factor in determining feed intake and nutrient requirements.
- Production level: Animals in different production stages (e.g., growth, lactation, gestation) have specific nutritional demands.
- Environmental conditions: Factors like temperature, humidity, and housing systems can impact feed intake and nutrient utilization.
Practical Applications of the Linders Feed Chart
The Linders Feed Chart is a valuable tool for animal nutritionists and farmers. It provides essential information on the nutrient requirements of different species and life stages, making it possible to formulate optimal feed rations that meet the specific needs of each animal.
One of the most important uses of the chart is to determine the energy and protein requirements of animals. The chart provides data on the digestible energy (DE) and crude protein (CP) content of various feedstuffs, allowing nutritionists to calculate the amount of each nutrient that an animal needs based on its age, weight, and activity level.
Example of Ration Formulation
For example, a dairy cow in early lactation has high energy and protein requirements to support milk production. Using the Linders Feed Chart, a nutritionist can determine that the cow needs approximately 25 Mcal of DE and 18% CP in its diet. The nutritionist can then use the chart to select feedstuffs that provide these nutrients in the correct proportions, ensuring that the cow receives the optimal nutrition for its needs.
Comparing Linders Feed Chart with Other Feeding Standards
The Linders Feed Chart is a valuable tool for estimating feed requirements for horses, but it is not the only feeding standard available. Other commonly used standards include the National Research Council (NRC) Nutrient Requirements of Horses and the Kentucky Equine Research (KER) Equine Nutrition System. Each of these standards has its own strengths and weaknesses, and the best choice for a particular horse will depend on its individual needs.
One of the main similarities between the Linders Feed Chart and other feeding standards is that they all use the same basic principles to estimate feed requirements. These principles include the horse's body weight, activity level, and age. However, there are also some key differences between the standards.
NRC Nutrient Requirements of Horses
The NRC Nutrient Requirements of Horses is a comprehensive feeding standard that provides detailed recommendations for the nutrient requirements of horses of all ages and activity levels. The NRC standard is based on extensive research and is considered to be the most accurate and up-to-date feeding standard available.
One of the strengths of the NRC standard is that it provides specific recommendations for the intake of all essential nutrients, including vitamins, minerals, and amino acids. This makes it a valuable tool for formulating diets that meet the specific needs of individual horses.
However, the NRC standard can also be complex and difficult to use. It requires a thorough understanding of equine nutrition and the ability to interpret the data provided in the tables. This can make it challenging for horse owners to use the NRC standard to formulate diets on their own.
KER Equine Nutrition System
The KER Equine Nutrition System is a user-friendly feeding standard that is designed to be easy to use for horse owners. The KER system provides general recommendations for the intake of essential nutrients, but it does not provide the same level of detail as the NRC standard.
One of the strengths of the KER system is that it is easy to use. The system provides a simple calculator that can be used to estimate the feed requirements of a horse based on its body weight, activity level, and age. This makes it a good choice for horse owners who are not familiar with equine nutrition.
However, the KER system can also be less accurate than the NRC standard. The system does not provide specific recommendations for the intake of all essential nutrients, and it can be difficult to adjust the recommendations to meet the specific needs of individual horses.
Considerations for Using the Linders Feed Chart
While the Linders Feed Chart provides a valuable framework for livestock feeding, it's crucial to acknowledge its limitations and caveats to ensure appropriate application and avoid potential pitfalls.
Limitations of the Linders Feed Chart
- Limited animal species coverage: The chart primarily focuses on cattle, and its accuracy may vary when applied to other species.
- Assumptions and simplifications: The chart assumes average animal performance and feed quality, which may not always align with specific conditions.
- Lack of regional specificity: The chart does not account for regional variations in feed availability and quality, which can impact nutrient requirements.
Importance of Considering Individual Animal Requirements
The Linders Feed Chart provides general guidelines, but it's essential to consider the unique needs of individual animals. Factors such as breed, age, body condition, and health status can influence nutrient requirements and should be taken into account when determining feed rations.
Importance of Considering Local Feed Availability
The availability and cost of feed ingredients vary significantly across regions. It's crucial to consider the local feed market and adjust feed rations accordingly to ensure cost-effectiveness and nutrient adequacy.
Advanced Applications of the Linders Feed Chart
The Linders Feed Chart is a versatile tool that can be used for complex diet formulation. It allows nutritionists to create diets that meet the specific nutrient requirements of animals while considering factors such as feed availability, cost, and environmental impact.
One advanced application of the Linders Feed Chart is to address specific nutritional challenges. For example, it can be used to formulate diets for animals with allergies or sensitivities to certain ingredients. It can also be used to create diets for animals with specific health conditions, such as diabetes or kidney disease.
Formulating Complex Diets
The Linders Feed Chart can be used to formulate complex diets that meet the specific nutrient requirements of animals. This is done by combining different feedstuffs in proportions that provide the desired levels of nutrients. The chart can also be used to calculate the cost of diets and to compare the nutritional value of different feedstuffs.
Addressing Specific Nutritional Challenges
The Linders Feed Chart can also be used to address specific nutritional challenges. For example, it can be used to formulate diets for animals with allergies or sensitivities to certain ingredients. It can also be used to create diets for animals with specific health conditions, such as diabetes or kidney disease.
Final Summary
In conclusion, the Linders Feed Chart is an indispensable resource for animal nutritionists, offering a comprehensive and reliable approach to determining optimal feed rations. Its versatility and ease of use make it a valuable tool for ensuring the health and productivity of livestock.
