In the quest for sustainable and economically viable animal feed, the industry is constantly exploring alternative ingredients. This comprehensive guide delves into Palmpitschilfers (PKE), a significant by-product of the Ruwe palmolie industry, and its pivotal role in modern animal nutrition. As demand for traditional feedstuffs like corn and soybean meal grows, understanding PKE is essential for feed manufacturers and livestock farmers alike.

Wat is een palmpitschilferspoelmachine (PKE)?

Palmpitschilfers (PKE), also known as Palm Kernel Cake (PKC), is a by-product derived from the mechanical extraction of oil from the kernel of the oil palm fruit (Elaeis guineensis). The process starts with the Oliepalmfruitbos, which is processed to extract palm oil. The remaining nut is then cracked to obtain the Palmpit. This kernel is then crushed in an expeller press to extract Palm Kernel Oil, and the solid residue left behind is the PKE.

This process makes PKE an abundant and valuable resource, particularly in major palm oil-producing regions like Southeast Asia. Instead of becoming waste, it is repurposed into a valuable feed ingredient, contributing to a more circular economy. Its composition is primarily known for a moderate protein content and, most notably, a very high level of dietary fiber.

The Detailed Nutritional Profile of Palm Kernel Expeller (PKE)

De voedingswaarde van Palmpitschilfers (PKE) can vary based on the oil extraction efficiency and the amount of shell remaining. However, a typical analysis provides a solid baseline for feed formulation. It is highly regarded as a source of energy and fiber, making it particularly suitable for certain types of livestock.

Here is a typical nutritional breakdown:

• Ruwe eiwitten: 14-18%
• Ruwe celstof: 16-22%
• Ruw vet/olie: 8-12%
• Energy (Metabolizable): ~1,700-2,000 kcal/kg for poultry, significantly higher for ruminants.
• Mineralen: A good source of phosphorus, copper, zinc, and manganese.

Compared to soybean meal, PKE has lower protein content and higher fiber. This high fiber, rich in Non-Starch Polysaccharides (NSPs), is what makes its application for monogastric animals (like poultry and swine) more challenging than for ruminants. For a more detailed analysis, you can review its profile on gezaghebbende bronnen zoals Feedipedia.

5 belangrijke voordelen van het gebruik van PKE in diervoeder

Incorporeren Palmpitschilfers (PKE) into feed rations offers several compelling advantages for the animal feed industry.

1. Kosteneffectiviteit: PKE is often significantly cheaper than conventional protein and energy sources like corn and soybean meal, helping to reduce overall feed costs.
2. Hoge beschikbaarheid: As a by-product of one of the world’s most produced vegetable oils, PKE is available in large quantities year-round.
3. Excellent Fiber Source: Its high fiber content is extremely beneficial for the digestive health of ruminant animals, promoting healthy rumen function.
4. Good Palatability for Ruminants: Cattle, in particular, find PKE palatable, which encourages consistent feed intake and performance.
5. Duurzaamheid: Using PKE reduces waste from the palm oil industry, turning a by-product into a valuable resource and supporting agricultural sustainability.

Practical Applications of Palm Kernel Expeller (PKE) for Livestock

The unique nutritional profile of Palmpitschilfers (PKE) dictates its suitability for different animal species. Understanding these nuances is key to maximizing its benefits.

Ruminants are where PKE truly shines. Their multi-chambered stomachs are designed to ferment and digest high-fiber materials efficiently. For dairy and beef cattle, PKE serves as an excellent source of bypass protein and energy. Studies published in journals like the Tijdschrift voor zuivelwetenschap have consistently shown its effectiveness. Inclusion rates can be as high as 30-50% in the total diet, making it a staple in many cattle-producing regions.

Using Palm Kernel Expeller (PKE) in Poultry Diets (Broilers and Layers)

Gebruiken Palmpitschilfers (PKE) in poultry diets is more complex. The high fiber content and gritty texture can negatively impact digestibility and feed intake for chickens. However, with proper treatment, its use is possible at lower inclusion rates (typically 5-10%). Supplementing the feed with NSP-degrading enzymes is a common strategy to break down the complex fibers, making nutrients more accessible. Research continues to explore methods like fermentation to improve its value for poultry, as noted in studies in publications like Pluimveewetenschap.

Similar to poultry, the high fiber in PKE limits its use in pig diets, especially for young, growing pigs. However, it can be effectively used in the diets of gestating sows, where high fiber can promote satiety and gut health. For growers and finishers, inclusion rates are generally kept below 15% to avoid any negative impact on growth performance.

Limitations and Challenges of Using PKE

Despite its benefits, there are challenges to consider when using Palmpitschilfers (PKE). Quality can be inconsistent, depending on the oil extraction process, which affects protein, oil, and fiber levels. The presence of crushed Palm Kernel Shell can increase the grittiness and reduce palatability.

Furthermore, like many agricultural commodities stored in tropical climates, PKE is susceptible to mycotoxin contamination, particularly aflatoxins. Proper sourcing from reputable suppliers and routine quality control are crucial to mitigate these risks. The Food and Agriculture Organization (FAO) provides extensive resources on managing mycotoxin risks in animal feed.

3 Proven Ways to Improve the Nutritional Value of Palm Kernel Expeller (PKE)

To overcome its limitations, especially for monogastric animals, researchers and feed technologists have developed several enhancement strategies.

1. Enzyme Supplementation: Adding specific enzymes (e.g., cellulase, xylanase, mannanase) to the feed helps break down the complex fiber structures, releasing trapped nutrients.
2. Solid-State Fermentation: This process uses beneficial microbes (like Aspergillus niger of Trichoderma) to ferment the PKE. This can significantly increase its protein content and decrease its fiber level, making it more suitable for poultry and swine.
3. Physical Processing: Simple methods like fine grinding can improve the texture and digestibility of Palmpitschilfers (PKE), making it easier for animals to consume and digest.

Conclusie: De toekomst van PKE in diervoeding

Palmpitschilfers (PKE) stands out as a powerful resource for the global animal feed industry. Its cost-effectiveness, high availability, and sustainability make it an attractive alternative to traditional feed ingredients. While it is a perfect fit for ruminants, ongoing technological advancements are steadily unlocking its potential for poultry and swine.

As the world population grows and the demand for animal protein rises, leveraging resourceful by-products like PKE is not just an economic choice—it’s a necessary step towards a more sustainable and efficient future for agriculture.
