As the global demand for sustainable and cost-effective animal feed ingredients grows, one product consistently stands out: Palm Kernel Expeller (PKE). This powerful by-product of the palm oil industry, which also produces Crude Palm Oil, is a cornerstone of livestock nutrition in many parts of the world, offering a unique blend of energy, protein, and fiber. Understanding its properties is key to unlocking its full potential for agricultural success.
Whether you’re a seasoned farmer, a feed formulator, or new to the agricultural industry, this guide will walk you through everything you need to know about Palm Kernel Expeller (PKE). We will explore its production, critical specifications, and the incredible benefits it brings to animal nutrition.
What is Palm Kernel Expeller (PKE)?
Palm Kernel Expeller (PKE) is a by-product derived from the mechanical extraction of oil from the kernel of the oil palm fruit. After the Palm Kernel is crushed to release its valuable Palm Kernel Oil, the remaining solid, fibrous material is PKE. It is also sometimes referred to as Palm Kernel Cake (PKC).
This material is rich in protein, energy, and minerals, making it a highly sought-after ingredient for compound animal feeds. Unlike some other feed options, Palm Kernel Expeller (PKE) is celebrated for its balance of nutrients, particularly its high fiber content, which is exceptionally beneficial for ruminant animals like cattle.

How is Palm Kernel Expeller (PKE) Produced?
The production of PKE is a straightforward mechanical process. It begins after the flesh from the Oil Palm Fruit Bunch has been processed. The remaining nut is cracked to reveal the palm kernel, which is the primary source of palm kernel oil and, subsequently, Palm Kernel Expeller (PKE).
The Extraction Process
The kernels are crushed and heated to break down the oil-bearing cells. Then, they are fed into a mechanical screw press or “expeller,” which exerts immense pressure to squeeze out the oil. The dry, solid mass left behind is the Palm Kernel Expeller (PKE). This process avoids the use of chemicals like hexane, which are common in solvent extraction methods.
Key Specifications of High-Quality Palm Kernel Expeller (PKE)
The nutritional quality of Palm Kernel Expeller (PKE) can vary based on the source and processing method. However, high-quality PKE generally adheres to specific nutritional profiles. Understanding these specs is crucial for formulating balanced animal diets.
- Crude Protein (CP): Typically ranges from 14-18%. This protein is vital for muscle development, milk production, and overall animal growth.
- Crude Fiber (CF): High fiber content, usually between 16-22%. This is a key reason why PKE is excellent for ruminants, as it supports healthy rumen function. For more details on fiber in animal diets, you can review research from journals like Animal Feed Science and Technology.
- Crude Fat/Oil: The residual oil content is typically 5-10%. This fat is a great source of concentrated energy for livestock.
- Moisture: Should be below 12% to prevent mold growth and ensure a longer shelf life.
- Metabolizable Energy (ME): Provides a good level of energy, making it a valuable component for maintaining animal productivity.
5 Ultimate Benefits of Using Palm Kernel Expeller (PKE) in Animal Feed
Incorporating PKE into livestock diets offers a wealth of advantages, making it a smart choice for modern agriculture.
1. Highly Cost-Effective
As a by-product, Palm Kernel Expeller (PKE) is often more affordable than primary feed ingredients like soybean meal or corn. This allows farmers to reduce feed costs without compromising on essential nutrients.
2. Excellent Source of Fiber
The high fiber content promotes good gut health, particularly in ruminants like cattle, sheep, and goats. It aids in proper rumen fermentation, which is essential for nutrient absorption and preventing metabolic issues. The Food and Agriculture Organization (FAO) provides extensive resources on the importance of fiber in livestock.
3. Good Protein and Energy Balance
Palm Kernel Expeller (PKE) provides a balanced combination of protein for growth and fat for energy. This dual-purpose nutrition supports everything from weight gain in beef cattle to milk yield in dairy cows.
4. Improves Feed Texture and Palatability
When mixed into a total mixed ration (TMR), PKE can improve the texture and reduce the dustiness of the feed. While some animals may need time to adapt to its taste, it is generally well-accepted, especially by cattle.
5. Sustainable and Readily Available
Using a by-product like Palm Kernel Expeller (PKE) contributes to a more sustainable food system by minimizing waste. Along with other useful materials like Palm Kernel Shell, it ensures that every part of the palm fruit is utilized efficiently.

Common Uses of Palm Kernel Expeller (PKE) Across Livestock
PKE is a versatile ingredient, but its application varies depending on the animal’s digestive system.
Ruminants (Cattle, Sheep, Goats)
This is the primary market for Palm Kernel Expeller (PKE). Its high fiber and moderate protein content are ideal for the digestive systems of ruminants. It is widely used in feed for both dairy and beef cattle to support milk production and growth.
Monogastrics (Poultry and Swine)
Due to its high fiber content, PKE is used more sparingly in diets for poultry and pigs. High fiber can be difficult for these animals to digest. However, recent studies published in journals like Cambridge’s Animal Journal explore using enzymes to improve its digestibility, opening new possibilities for its use.
Other Uses
The versatility of Palm Kernel Expeller (PKE) also extends to aquaculture, where it can be included in feed formulations for certain fish species. It is also sometimes used as a biofuel feedstock.
Potential Limitations and Important Considerations
While PKE is an excellent resource, it’s important to be aware of a few factors:
- Palatability: Some animals may find the gritty texture of PKE unpalatable at first. It is often introduced gradually and mixed with more palatable feeds like molasses.
- Nutrient Variability: Quality can differ between suppliers. It is essential to source Palm Kernel Expeller (PKE) from a reputable provider who can offer a consistent product with a guaranteed analysis.
- Mycotoxin Risk: Like any feed ingredient, PKE must be stored in a cool, dry place to prevent the growth of mold and the development of mycotoxins. A study from the National Institutes of Health (NIH) highlights the importance of proper feed storage to avoid contamination.
Ultimately, the success of using Palm Kernel Expeller (PKE) lies in balanced formulation and sourcing high-quality products. When used correctly, it is one of the most reliable feed components available.

Frequently Asked Questions (FAQ)
1. What is the difference between Palm Kernel Expeller (PKE) and Palm Kernel Cake (PKC)?
The terms are often used interchangeably. However, technically, PKE is produced via mechanical expeller pressing, while PKC can also refer to the by-product from solvent extraction. PKE typically has a higher residual oil content than solvent-extracted cake.
2. Is Palm Kernel Expeller (PKE) suitable for all animals?
PKE is ideal for ruminants like cattle due to its high fiber. Its inclusion level in diets for monogastric animals like poultry and swine should be limited unless specific enzymes are added to aid digestion.
3. How should PKE be stored?
It should be stored in a dry, well-ventilated area away from direct sunlight to prevent moisture absorption and mold growth. Proper storage is key to maintaining its nutritional quality and safety.
