Palm Kernel Expeller (PKE): The #1 Complete Guide for Animal Feed (2025)

In the quest for sustainable and affordable livestock nutrition, farmers and feed manufacturers are constantly exploring alternative ingredients. This is where 棕榈核榨油机 （PKE） emerges as a powerful contender, offering a unique blend of cost-efficiency and nutritional value. But what exactly is it, and how can it be effectively integrated into animal diets?

This complete guide for 2025 breaks down everything you need to know about Palm Kernel Expeller (PKE). We’ll explore its origins, nutritional benefits, and practical applications, providing you with the essential knowledge to make informed decisions for your animal feed strategy.

棕榈仁压榨机（PKE）到底是什么？

Palm Kernel Expeller (PKE) is a co-product derived from the palm oil industry. After the palm fruit’s flesh is processed to extract 毛棕榈油, the hard nut in the center remains. Inside this nut is the 棕榈仁, which is rich in a different type of oil known as 棕榈油.

PKE is the solid, protein-rich material left behind after the oil is mechanically extracted from these kernels using an expeller press. This process makes it a valuable and sustainable resource, transforming a potential waste product into a key ingredient for the global animal feed market. The quality and composition of 棕榈仁榨油机（PKE） can vary based on the efficiency of the oil extraction process.

棕榈仁压榨油（PKE）的营养成分

Understanding the nutritional makeup of Palm Kernel Expeller (PKE) is crucial for its proper use. While not a complete feed on its own, it serves as an excellent base ingredient, particularly for ruminants. It is known for its high fiber and moderate protein content.

Here’s a typical nutritional breakdown:

• 粗蛋白（CP）： 14-18%
• 粗纤维（CF）： 15-22%
• 残留油/脂肪： 5-12%
• Metabolizable Energy (ME): Varies by species, but is significant for ruminants.
• 矿物质： Contains essential minerals like phosphorus, magnesium, and iron. However, it is high in copper, which requires careful formulation for sheep.

Due to its composition, 棕榈仁榨油机（PKE） is valued more for its fiber and energy than as a primary protein source. For a detailed scientific analysis of its components, Feedipedia offers a comprehensive database on its nutritional values.

5 Key Benefits of Using Palm Kernel Expeller (PKE) in Animal Feed

Incorporating PKE into feed rations offers several compelling advantages for livestock producers.

1. 卓越的成本效益

One of the primary drivers for using 棕榈仁榨油机（PKE） is its affordability. It is often significantly cheaper than conventional feed ingredients like soybean meal or corn, allowing farmers to reduce production costs without compromising energy intake for their herds.

2. Enhanced Sustainability

PKE is a by-product, meaning it makes use of material that would otherwise be discarded. Its utilization helps create a more circular economy within the agricultural sector, reducing waste and promoting resource efficiency. This approach mirrors the full utilization of the palm tree, where other parts like the 油棕果串 are also used, creating a zero-waste cycle. This aligns with modern sustainable farming practices, a topic extensively covered by organizations like the 联合国粮食及农业组织（FAO）.

3. Excellent Source of Fiber

高纤维含量 棕榈仁榨油机（PKE） is particularly beneficial for ruminants like cattle, sheep, and goats. This fiber promotes good rumen function, stimulates digestion, and contributes to overall gut health, leading to better feed efficiency and animal well-being.

4. Reliable Energy Source

The residual oil left in the PKE after the extraction process provides a dense and readily available source of energy for livestock. This fat content helps improve the body condition of animals and can support milk production in dairy cows.

5. Year-Round Availability

作为全球庞大棕榈油产业的产物， 棕榈仁榨油机（PKE） is consistently available throughout the year. This reliability prevents feed formulation disruptions that can occur with seasonal crops.

Applications: Which Animals Can Consume Palm Kernel Expeller (PKE)?

While PKE is versatile, its suitability varies by animal species due to its high fiber content.

• Ruminants (Cattle, Goats, Sheep): This is the ideal application. Ruminants can efficiently digest the high fiber in PKE, making it a staple in many beef and dairy cattle diets worldwide. It can often comprise up to 50% of the concentrate ration for cattle. For more on ruminant nutrition, academic resources like the 动物科学杂志 provide in-depth research.
• Poultry: Use in poultry is limited. The high fiber is difficult for chickens to digest and can hinder nutrient absorption. If used, it should be at very low inclusion rates (typically under 5%) and preferably in layer hen diets rather than for broilers.
• 猪： Similar to poultry, the high fiber content makes 棕榈仁榨油机（PKE） less suitable for pigs. It can be used in small quantities for sow diets but is generally avoided for growing pigs.
• 水产养殖： Research has shown that PKE can be included in the diets of some herbivorous fish species, offering a low-cost plant-based protein alternative.

Limitations and Considerations When Using Palm Kernel Expeller (PKE)

To use PKE effectively, it’s essential to be aware of its limitations.

• Grit and Shell Content: Poorly processed PKE can contain a high percentage of 棕榈壳, which reduces its digestibility and palatability. Always source from reputable suppliers who guarantee low shell content.
• Amino Acid Imbalance: 棕榈仁榨油机（PKE） is deficient in key essential amino acids like lysine and methionine. Rations must be balanced with other protein sources to meet the complete nutritional requirements of the animals.
• 霉菌毒素风险： Like any feedstuff, PKE is susceptible to mold and mycotoxin contamination if not stored properly in a cool, dry place. Poor storage can lead to health issues in livestock. The World Health Organization (WHO) provides information on the dangers of mycotoxins.
• 适口性： Some animals may find PKE less palatable than other feeds. It is often introduced gradually and mixed with more palatable ingredients like molasses to encourage intake.

Sourcing and Quality Control for Palm Kernel Expeller (PKE)

The success of using 棕榈仁榨油机（PKE） hinges on quality. When sourcing, look for a supplier who can provide a product analysis certificate. Key quality indicators to check for are:

• 水分含量： Should be below 12% to prevent mold growth.
• Crude Protein and Fiber Levels: Should be within the expected ranges.
• 壳牌内容： Should be as low as possible, ideally under 5%.
• Color and Smell: Good quality PKE has a light brown color and a fresh, nutty aroma. A dark color or musty smell can indicate poor quality or spoilage.

结论：PKE 在动物营养领域的未来

棕榈仁榨油机（PKE） stands out as a valuable, sustainable, and economically viable feed ingredient, especially for the ruminant sector. Its ability to convert an industrial by-product into a source of energy and fiber for livestock is a testament to agricultural innovation.

By understanding its nutritional profile, benefits, and limitations, farmers and feed formulators can safely incorporate PKE to lower costs and enhance the sustainability of their operations. When sourced carefully and balanced correctly, PKE is more than just a filler—it’s a strategic component of modern animal nutrition.
