In the world of animal nutrition, finding sustainable, cost-effective, and nutrient-rich feed ingredients is a constant pursuit. One such ingredient that has gained significant traction is the 棕榈仁榨油机(PKE). This valuable by-product of the palm oil industry offers a fantastic balance of energy, protein, and fiber, making it a staple for livestock farmers worldwide.
This comprehensive 2025 guide explores everything you need to know about PKE, from its production process and nutritional benefits to its primary uses and quality specifications. Whether you’re a seasoned farmer or new to animal husbandry, understanding this feed component is key to optimizing your feed strategy.
什么是棕榈仁榨油机(PKE)?
PKE is a by-product derived from the mechanical extraction of oil from the kernel of the oil palm fruit. After the 油棕果串 is harvested to produce 毛棕榈油,剩下的坚果被敲碎,露出 棕榈仁. This kernel is then crushed, or “expelled,” to extract valuable 棕榈油.
The solid residue left behind is the 棕榈核榨油机. It’s important not to confuse this feed ingredient with 棕榈壳, which is the harder outer casing and is primarily used as a biofuel. PKE is renowned for its high fiber and moderate protein content, positioning it as an excellent feed for ruminant animals.

PKE 的营养成分
The value of any feed ingredient lies in its nutritional composition. Palm Kernel Expeller provides a unique blend of energy, fiber, and protein that supports livestock health and productivity. While the exact values can vary based on the extraction process, a typical profile is as follows:
| 营养 | Typical Range (%) |
|---|---|
| 粗蛋白(CP) | 14 – 18% |
| Crude Fibre (CF) | 16 – 20% |
| Crude Fat / Oil | 8 – 12% |
| Metabolizable Energy (ME) | 10 – 12 兆焦/千克 |
| Shell Content | <5% (in high-quality PKE) |
This composition makes the expeller particularly suitable for cattle, goats, and sheep, where its high fiber content can aid rumen function and digestion. For more detailed analysis, research from institutions like the MDPI Animals Journal provides in-depth studies on its use.
6+ Proven Benefits of Using PKE in Animal Feed
合并 棕榈仁榨油机(PKE) into livestock diets offers several compelling advantages for modern agriculture.
1. Highly Cost-Effective Ingredient
Compared to other common protein and energy sources like soybean meal or corn, PKE is often more affordable. This price advantage allows farmers to lower overall feed costs without compromising on essential nutrients, directly impacting profitability.
2. 膳食纤维的极佳来源
The high fiber content is a standout feature. For ruminants, this fiber is crucial for stimulating cud-chewing, promoting saliva production, and maintaining a healthy pH in the rumen. This leads to better overall digestive health and efficient nutrient absorption.
3. Good Balance of Protein and Energy
With a crude protein content of 14-18%, PKE serves as a valuable protein source for muscle development and milk production. The residual oil also provides a dense source of energy, supporting the daily maintenance and growth requirements of livestock.
4. Sustainable and Eco-Friendly
As a by-product, this feed component contributes to a more circular economy. Utilizing it as animal feed reduces waste from the palm oil industry, making it an environmentally responsible choice. Sourcing from certified suppliers, as promoted by organizations like the 可持续棕榈油圆桌会议(RSPO),进一步增强其可持续性资质。
5. Improves Feed Palatability and Texture
Many animals find the nutty aroma of Palm Kernel Expeller highly palatable, which can help increase feed intake. Its texture can also improve the consistency of total mixed rations (TMR), preventing animals from sorting out individual ingredients and ensuring a more balanced diet.
6. Long Shelf Life and Stability
When stored correctly in a cool, dry place, PKE has an excellent shelf life. Its low moisture content and dense nature make it less prone to spoilage compared to other feed ingredients, ensuring a consistent supply for your livestock.
Common Uses of Palm Kernel Expeller
While PKE is most famous as a feed for dairy and beef cattle, its applications extend to other livestock as well. Here’s a breakdown of its primary uses:
- 奶牛和肉牛: This is the largest market for 棕榈仁榨油机(PKE). It’s an ideal supplement for grazing animals, providing the necessary protein and energy to support milk yield and weight gain.
- 绵羊和山羊: Similar to cattle, small ruminants benefit greatly from the fiber and protein in this feed, especially during periods of high nutritional demand like lactation.
- 家禽和猪: PKE can be included in the diets of monogastric animals like chickens and pigs, but typically at lower inclusion rates due to its high fiber content, which they cannot digest as efficiently as ruminants.
- Biofuel Research: Beyond animal feed, researchers are exploring the potential of this by-product as a biomass feedstock for producing renewable energy, as detailed in various studies on 科学导向.

Quality Specifications to Look For
Not all PKE is created equal. When purchasing 棕榈核榨油机, it’s vital to assess its quality to ensure you’re getting a safe and effective product.
- Low Shell Content: A high concentration of shell fragments reduces the nutritional value and digestibility. High-quality PKE should have a minimal shell content.
- Freshness and Aroma: The product should have a fresh, nutty smell. A sour or musty odor can indicate spoilage or mold growth, which may be associated with harmful mycotoxins.
- 水分含量: Ideal moisture content is below 12%. Higher levels can lead to mold and spoilage during storage.
- Aflatoxin Levels: It is crucial to ensure the product is tested for aflatoxins, which are toxic compounds produced by certain molds. Reputable suppliers should provide a Certificate of Analysis (COA). The 联合国粮食及农业组织(FAO) provides guidelines on safe levels in animal feed.

常见问题 (FAQ)
Is PKE good for all animals?
This feed is most beneficial for ruminants (cattle, sheep, goats) due to its high fiber content. It can be used for poultry and swine but at much lower inclusion rates to avoid digestive issues.
How is PKE different from Palm Kernel Cake (PKC)?
The terms are often used interchangeably. Technically, “expeller” refers to mechanical pressing, while “cake” can also refer to solvent-based extraction. 棕榈核榨油机 usually has a higher residual oil content than solvent-extracted cake.
What are the ideal storage conditions for Palm Kernel Expeller (PKE)?
PKE should be stored in a cool, dry, and well-ventilated area away from direct sunlight. It should be kept off the ground on pallets to prevent moisture absorption and reduce the risk of mold contamination.
结论
棕榈仁榨油机(PKE) stands out as a remarkable resource in the agricultural sector. Its unique combination of being a cost-effective, nutrient-dense, and sustainable feed ingredient makes it an invaluable asset for livestock farmers aiming to enhance productivity and profitability.
By understanding its nutritional benefits and adhering to quality standards, you can effectively integrate PKE into your feeding programs. This not only supports the health of your animals but also contributes to a more efficient and environmentally friendly farming operation in 2025 and beyond.
