In the world of animal nutrition, finding cost-effective, high-energy feed ingredients is a constant pursuit. Enter the 棕榈核榨油机 （PKE）, a significant by-product of the palm oil industry that has become a cornerstone in livestock diets worldwide. This guide explores everything you need to know about this valuable feed component, from its production to its precise applications.
Whether you’re a farmer, nutritionist, or trader, understanding the nuances of Palm Kernel Expeller (PKE) is crucial for optimizing animal health and farm profitability. Let’s dive into the details.
棕榈仁压榨机（PKE）到底是什么？
棕榈仁压榨机（PKE）是从棕榈仁中机械提取油后留下的固体残留物 棕榈仁 of the palm fruit. It is a coarse, brownish material rich in protein, fiber, and energy, making it a popular ingredient in compound feeds, particularly for ruminant animals like cattle.
Often referred to as Palm Kernel Cake (PKC), it’s important to distinguish it from Palm Kernel Meal (PKM), which typically undergoes a solvent extraction process. The mechanical “expeller” process used for PKE generally leaves a higher residual oil content, which translates to a higher energy value.
棕榈仁压榨机（PKE）是如何生产的？
The journey of PKE begins with the 油棕果串. After the fleshy part is processed to extract 毛棕榈油, the nut remains. This nut is cracked, separating the valuable 棕榈壳 (often used for biofuel) from the kernel itself. This kernel is the primary source of 棕榈油.
- Crushing: The palm kernels are crushed to break them down.
- Heating: The crushed kernels are heated to facilitate oil extraction.
- Extraction: The heated material is fed into a mechanical screw press (an expeller) that applies immense pressure to squeeze out the oil.
- The By-Product: The solid, cake-like material that remains is the 棕榈仁榨油机（PKE）.
- 成本效益： PKE is often more affordable than other protein sources like soybean meal.
- 高可用性： As a by-product of the massive palm oil industry, it is widely available year-round.
- 可持续性： 使用 棕榈仁榨油机（PKE） adds value to a by-product, reducing waste and promoting a circular economy.
- 质量变异性： Nutritional content can vary between suppliers.
- 适口性： Some animals may find its gritty texture less palatable, requiring gradual introduction.
- High Copper: Unsuitable for sheep in high concentrations.
The Complete Nutritional Profile of PKE
The value of this feed ingredient lies in its dense nutritional makeup. While quality can vary based on the extraction process and shell content, a typical analysis provides a good overview of what makes PKE so useful.
Macronutrients: Protein, Fiber, and Energy
PKE is considered a balanced source of protein and energy. It typically contains 14-18% crude protein, which is vital for animal growth and milk production. Its high crude fiber content (15-22%) is particularly beneficial for ruminants, as it supports healthy rumen function. The residual oil (5-10%) provides a concentrated source of energy.
Minerals and Other Components
PKE is a good source of essential minerals like phosphorus, magnesium, iron, and manganese. However, it’s notably high in copper, which makes it an excellent supplement for cattle but requires careful formulation for sheep, which are sensitive to copper toxicity. For more on ruminant mineral requirements, you can refer to resources from the 默沙东兽医手册.
Primary Uses of PKE in Animal Feed
The unique nutritional specs of Palm Kernel Expeller (PKE) make it suitable for a variety of livestock, though it excels in certain applications.
A Staple for Ruminant Nutrition (Cattle, Goats)
PKE is most widely used in the diets of dairy and beef cattle. Its high fiber content and moderate protein level make it an ideal complement to pasture-based systems. It serves as a cost-effective bulk feed that promotes satiety and supports milk fat production. Research published in journals like the 动物科学杂志 frequently confirms its efficacy in cattle rations when balanced correctly.
Use in Monogastric Diets (Poultry and Swine)
The use of PKE in poultry and swine diets is more limited due to its high fiber content, which these animals cannot digest as efficiently as ruminants. However, it can be included at lower levels (typically 5-10%) to reduce feed costs without significantly impacting performance. Enzyme supplementation can help improve its digestibility for these animals.
Key Technical Specifications for Quality PKE
When purchasing Palm Kernel Expeller (PKE), buyers rely on a set of technical specifications to ensure quality and consistency. These parameters determine its nutritional value and shelf life.
| 参数 | Typical Range | Importance |
|---|---|---|
| 湿度 | < 12% | Prevents mold growth and ensures stability |
| 粗蛋白（CP） | 14 – 18% | Essential for growth and production |
| 粗脂肪（油） | 5 – 10% | Provides concentrated energy |
| 粗纤维（CF） | 15 – 22% | Aids digestion in ruminants |
| 灰烬 | 3 – 6% | Indicates mineral content |
| Shell Content | < 5% | Low shell content means higher digestibility |
For official standards, organizations like the Codex Alimentarius provide international food standards, guidelines, and codes of practice.

The Global Market and Sustainability of Palm Kernel Expeller (PKE)
Indonesia and Malaysia are the world’s largest producers of 棕榈仁榨油机（PKE）. Major importing regions include the European Union, New Zealand, China, and South Korea, where it supports large-scale dairy and livestock industries. The global trade is robust, driven by the demand for affordable animal feed.
Sustainability is a critical aspect of the palm industry. Reputable suppliers often provide certification from organizations like the Roundtable on Sustainable Palm Oil (RSPO), ensuring the PKE comes from environmentally and socially responsible sources. A report from the RSPO can offer insights into the certification process and its importance.

常见问题 (FAQ)
Is PKE good for dairy cows?
Yes, PKE is an excellent feed for dairy cows. Its high fiber supports rumen health, and its protein and energy content contribute to milk production and quality.
What is the difference between Palm Kernel Expeller (PKE) and soybean meal?
PKE generally has lower protein (14-18%) and higher fiber compared to soybean meal (44-48% protein). It is valued as a balanced energy and fiber source, while soybean meal is primarily a protein supplement.
How should I store PKE?
PKE should be stored in a cool, dry place away from direct sunlight to prevent mold growth. Keeping moisture content below 12% is the key to long-term storage and quality preservation.
