In animal feeding, the most determining factor in price formation is the selection of the appropriate protein source.

Rapeseed and soy are important protein sources in animal feeding. Animal feeds contain a wide variety of ingredients, and when selecting protein sources, several factors need to be considered, such as price, nutrient content, and digestibility.

Rapeseed:

Rapeseed is an oilseed plant from which rapeseed oil can be extracted. The residue remaining after oil extraction, the by-products of rapeseed (for example, rapeseed meal, rapeseed cake, or rapeseed pellets) can be used in animal feeds.

• Protein Source: Both rapeseed meal and rapeseed cake can be good sources of protein. Poultry, in particular, require adequate protein for growth, egg production, and overall health. The protein derived from rapeseed contains essential amino acids that are indispensable for animals.
• Energy Source:Rapeseed meal contains less than 3% fat, while rapeseed cake contains more than 10% fat, which can serve as an energy source for poultry. Energy is vital for growth, egg production, and reproductive processes.
• Fiber:Both rapeseed meal and rapeseed cake contain fibers that influence digestion.
• Good value for money:The meal and cake produced during rapeseed oil extraction are often economically obtainable by-products, offering a good value for money in animal feeds.
• Geographic accessibility:Rapeseed can be grown successfully in many areas, and the processing of rapeseed seeds can be part of local or regional agricultural production. This can promote feed security and support the local economy.

When using rapeseed, it's important to consider early spoilage and the fact that rapeseed may contain certain antinutritive substances (such as glucosinolates, polyphenols, etc.) that can have negative effects on animal health. However, the PEELKO supplement developed by ROP Ltd. offers a solution to both problems. It inhibits the spoilage of rapeseed meal and rapeseed cake when treated with PEELKO, making it usable for up to 6 months from mixing. Additionally, it's important to note that rapeseed products treated with the PEELKO supplement are GMO-free.

Soy:

Soybean is one of the most important and widely used plant protein sources in animal feeding. Soybeans are high in protein and contain complete proteins, meaning they contain all essential amino acids required by animals. However, the antinutritive substances found in soybeans, such as trypsin inhibitors, glycinin, phytic acid, and lectins, can cause digestive issues for animals, especially monogastric animals (e.g., pigs, poultry). These antinutritive substances are neutralized through heat treatment in the case of soybeans.

Both plant protein sources have their advantages and disadvantages, and their application depends on specific feed and livestock farming conditions. It's important to maintain proper nutrient balance and consider animal health when selecting feeds. Additionally, proper processing technologies may be necessary during feeding to reduce the negative effects of potential antinutritive substances. In light of these factors, the PEELKO feed supplement offers a perfect solution for rapeseed, both in terms of its price and utilization in feed, as well as its GMO-free nature, providing further benefits.
