In the quest for sustainable and cost-effective animal nutrition, the global feed industry is constantly exploring valuable co-products. One of the most significant is Palm Kernel Expeller (PKE), a versatile ingredient derived from the palm oil industry. This guide offers a comprehensive look into what this feed component is, its rich nutritional profile, and how it’s revolutionizing feed formulations for livestock worldwide.
What is Palm Kernel Expeller (PKE)?
Palm Kernel Expeller is a co-product created during the extraction of oil from the Palm Kernel. The process begins after the Oil Palm Fruit Bunch is harvested to produce Crude Palm Oil. The inner kernel of the fruit is then processed to extract Palm Kernel Oil using a mechanical press. The remaining solid, fibrous material is the expeller.
This mechanical extraction method, known as the “expeller press,” is crucial as it ensures a significant amount of residual oil (typically 5-12%) remains in the final product. This residual oil makes PKE an excellent source of energy in animal diets.
Nutritional Profile of Palm Kernel Expeller
The nutritional value of PKE can vary based on oil extraction efficiency and shell content, but it generally offers a balanced profile of protein, fiber, and energy. It is a key ingredient for farmers looking to optimize feed costs without compromising on essential nutrients. Let’s break down the components of this valuable feed source.
Key Nutritional Components
- Crude Protein: This feed contains a moderate level of crude protein, typically ranging from 14-21%. While not as high as soybean meal, it provides essential amino acids for growth and milk production, particularly in ruminants.High Fiber: It is exceptionally rich in crude fiber (around 12-18%), which is highly beneficial for ruminant animals like cattle. This fiber promotes healthy rumen function and digestion.Energy Source: The residual palm kernel oil gives the expeller a high energy value. This makes it an effective ingredient for animals with high energy demands, such as dairy cows. You can explore a more detailed analysis in this ScienceDirect overview on palm kernel cake.Essential Minerals: The material is a good source of minerals like phosphorus, copper, zinc, and manganese, which are vital for bone development, immune function, and overall animal health.
Primary Uses of PKE in Animal Nutrition
Due to its unique nutritional makeup, this co-product is most suitable for certain types of livestock. Its application has become a cornerstone of feed management in many agricultural systems.
Excellent for Ruminant Feed (Cattle, Sheep, Goats)
PKE is a star performer in the diets of ruminants. The high fiber content is easily fermented in the rumen, providing a steady release of energy. It is widely used in dairy farming to boost the butterfat content of milk and is a cost-effective way to supplement the diets of beef cattle.
Strategic Use in Monogastric Diets (Poultry & Swine)
For monogastric animals like chickens and pigs, the high fiber content can be a limiting factor. However, it can be included at lower levels (typically 5-10%) in their diets. Modern advancements, such as the use of feed enzymes, can help break down the complex fibers, increasing the nutritional value of the ingredient for these animals.
A Growing Role in Aquaculture
As the aquaculture industry seeks sustainable, plant-based protein sources, PKE is gaining traction. It is being researched and used as a partial replacement for more expensive ingredients like fishmeal in the diets of certain fish species, contributing to more sustainable fish farming practices.
Key Benefits of Using Palm Kernel Expeller
Incorporating PKE into animal feed offers several compelling advantages, from economic savings to environmental sustainability.
- Economic Viability: As a co-product, this ingredient is significantly more affordable than primary feed ingredients like corn, barley, and soybean meal. This helps farmers reduce production costs substantially.Sustainability and Waste Reduction: Using co-products like Palm Kernel Expeller and Palm Kernel Shell adds value to the palm oil production chain, promoting a circular economy. It ensures that less of the palm fruit goes to waste, aligning with sustainable agricultural goals championed by organizations like the Food and Agriculture Organization (FAO).Improved Animal Health: The high fiber content is not just filler; it actively promotes good gut health in ruminants, preventing digestive issues. The presence of lauric acid in the residual oil also has known antimicrobial properties.High Palatability for Ruminants: Most ruminants find this feed highly palatable, especially when mixed with molasses, ensuring good feed intake.
Limitations and Considerations for Using PKE
While Palm Kernel Expeller is a fantastic resource, users should be aware of a few considerations to ensure its optimal use.
- Variability in Quality: Nutritional content can differ between suppliers based on the oil extraction process. It’s vital to source PKE from reputable suppliers who can provide a consistent product analysis.Grit and Shell Content: Poorly processed material can contain higher levels of shell, which reduces its digestibility. Low-shell PKE is a premium product with higher nutritional value.Mycotoxin Risk: Like many feed ingredients, PKE must be stored correctly in dry, cool conditions to prevent mold growth and mycotoxin contamination, a topic explored in detail by animal science journals such as this study on mycotoxins in feed.
The Future of PKE in a Circular Economy
The future for Palm Kernel Expeller is bright. Ongoing research is focused on enhancing its nutritional value through processes like fermentation and enzyme treatment. These technologies can break down the complex fibers, “upgrading” the feed to make it more suitable for poultry and swine, thus expanding its market reach.
As the world moves towards a more sustainable and circular economy, the role of co-products like this will only grow. Its ability to turn a potential waste stream into a high-value nutritional resource makes it a key player in the future of responsible agriculture.

Frequently Asked Questions
Is PKE good for dairy cows?
Absolutely. PKE is an excellent feed for dairy cows due to its high fiber and energy content, which supports rumen health and can increase the butterfat percentage in milk.
What is the difference between Palm Kernel Expeller (PKE) and Palm Kernel Cake (PKC)?
The terms are often used interchangeably. However, “expeller” specifically refers to a product from mechanical pressing, which leaves more oil. “Cake” can sometimes refer to the product of solvent extraction, which has a lower residual oil content.
Why is Palm Kernel Expeller not used in high quantities for chickens?
The high crude fiber content in Palm Kernel Expeller is difficult for chickens (monogastric animals) to digest. This can limit nutrient absorption, so it is typically only included at low percentages in poultry diets.
