棕榈仁压榨机（PKE）：2025 年 #1 终极指南

欢迎阅读您的完整指南 棕榈仁压榨机（PKE）, a crucial and cost-effective ingredient in the global animal feed industry. As demand for sustainable and affordable feed sources grows, understanding PKE’s role has never been more important. Whether you’re a farmer, nutritionist, or trader, this article provides the essential details on its uses, specifications, and market price.

This resource offers an in-depth look at what makes Palm Kernel Expeller (PKE) a popular choice for livestock, especially ruminants. We will explore everything from its nutritional profile to the economic factors influencing its value, giving you a comprehensive overview for 2025.

什么是棕榈仁压榨机（PKE）？

Palm Kernel Expeller (PKE) is a by-product derived from the mechanical extraction of oil from the kernel of the palm fruit. After the palm kernel is crushed to release its valuable oil, the remaining solid, fibrous material is PKE. It is known for its balanced energy and protein content, making it a highly sought-after commodity for animal feed formulations.

Often referred to as Palm Kernel Cake (PKC), this ingredient is prized for its high fiber content and moderate protein levels. The nutritional composition of Palm Kernel Expeller (PKE) makes it an excellent and economical feed component, particularly for cattle and other ruminant animals that can efficiently digest fibrous materials.

How is PKE Produced?

The production of Palm Kernel Expeller (PKE) is directly linked to the palm oil milling process. It begins with the 油棕果串, which contains a fleshy outer layer and a hard-shelled nut. Inside this nut lies the 棕榈仁, the source of both PKE and its valuable oil.

1. Sterilization and Stripping: Fresh fruit bunches are sterilized with steam to halt enzymatic activity and loosen the fruit. The fruits are then stripped from the bunch.
2. 采油： The fruit’s flesh is pressed to extract 粗棕榈油. The remaining nut contains the kernel and the hard shell, which can be processed into 棕榈仁壳, another useful biomass product.
3. 籽粒破碎： The kernels are separated, dried, crushed, and cooked to prepare them for oil extraction.
4. 机械压制： A screw press is used to mechanically extract 棕榈仁油 from the crushed kernels. The solid residue left behind is the 棕榈仁压榨机（PKE）.

This mechanical process ensures that a residual amount of oil (typically 5-12%) remains in the PKE, contributing to its energy value as a feed ingredient.

优质棕榈仁压榨机（PKE）的主要规格

质量 棕榈仁压榨机（PKE） is determined by its nutritional composition, which can vary based on the oil extraction process and the kernel’s quality. When sourcing PKE, it’s crucial to check the Certificate of Analysis (COA) for the following key parameters.

棕榈仁粕（PKE）的营养成分

• 粗蛋白（CP）： Typically ranges from 14% to 18%. This is a vital component for animal growth and milk production.
• 粗脂肪（油）： Generally between 5% and 12%. The residual oil is a great source of energy for livestock.
• Crude Fibre (CF): High levels, often 15% to 20%. While beneficial for ruminants, it can limit its use for monogastric animals like poultry.
• 水分： Should be below 12% to prevent mold growth and ensure a longer shelf life.
• 灰分含量： Represents the mineral content and is typically under 5%.

For more detailed information on feed compositions, the 联合国粮食及农业组织（粮农组织） provides extensive databases on animal feed resources. A consistent and high-quality Palm Kernel Expeller (PKE) supply is essential for predictable livestock performance.

The #1 Use of Palm Kernel Expeller (PKE): Animal Feed

主要应用 棕榈仁压榨机（PKE） is as an ingredient in compound feed for various types of livestock. Its unique nutritional profile makes it particularly suitable for certain animals.

反刍动物（牛、羊、山羊）棕榈仁粕

PKE is an exceptional feed for ruminants. Its high fiber content supports healthy rumen function, and its moderate protein and energy levels make it a perfect supplement for pasture-based diets. In dairy cattle, Palm Kernel Expeller (PKE) can improve milk fat content and is a cost-effective way to maintain body condition. Scientific studies, like those published in the 乳品科学杂志, often explore its impact on milk production.

PKE for Poultry and Swine

For monogastric animals like chickens and pigs, the use of PKE is more limited due to its high fiber content, which they cannot digest efficiently. However, it can be included at lower levels (typically 5-10%) in their diets. New research on enzyme treatments aims to improve the digestibility of 棕榈仁压榨机（PKE） 对于这些动物而言。.

Understanding Palm Kernel Expeller (PKE) Price Factors for 2025

价格 棕榈仁压榨机（PKE） is dynamic and influenced by a range of global and local factors. As a commodity, its value fluctuates based on supply, demand, and related markets.

Key Drivers of PKE Price:

• Palm Oil Market: PKE is a by-product, so its supply is tied to palm oil production. High palm oil output generally means more PKE is available, which can lower prices.
• 全球饲料需求： The price of competing feed ingredients like soybean meal and corn directly impacts PKE demand. When other feeds are expensive, demand for PKE rises.
• 物流和货运成本： A significant portion of the final PKE price comes from shipping. Major producers are Indonesia and Malaysia, so transportation costs to key markets like New Zealand, Europe, and China are a major factor. You can track commodity trends on platforms like IndexMundi.
• Quality Specifications: Higher protein and lower moisture content in a Palm Kernel Expeller (PKE) shipment will command a premium price.

Benefits and Limitations of Using PKE

尽管 棕榈仁压榨机（PKE） is an excellent feed ingredient, it’s important to understand both its advantages and its potential drawbacks.

好处：

• 经济实惠： It is often cheaper than other protein and energy sources like soybean meal.
• 高可用性： As a by-product of the massive palm oil industry, it is widely available year-round.
• 优质能源： The residual fat content provides a good source of slow-release energy.

局限性：

• 高纤维： Not ideal for monogastric animals in large quantities.
• 适口性： Some animals may find PKE less palatable than other feeds, requiring a gradual introduction.
• 可持续性问题： The link to palm oil production means it is crucial to source PKE from sustainable and certified suppliers. Organizations like the 可持续棕榈油圆桌会议（RSPO） are working to ensure environmentally responsible production.
