Feed Phosphates

Pioneer in high quality feed phosphates

Phosphates have long been core products for Aliphos. Production of inorganic feed phosphates on an industrial scale began at the Belgium factory in 1929. Subsequently, the range was extended to include chemically manufactured mono- and mono-dicalcium phosphate, as well as magnesium and mono-ammonium phosphates.

Output capacity was expanded in 1995 by the acquisition of the factory in Vlaardingen, the Netherlands. This produces special types of inorganic feed phosphates primarily for worldwide export under the WINDMILL brand name. Today, with a total capacity of over 300,000 tons a year, Aliphos is a main producer of inorganic feed phosphates and its products set the standard for quality all over the world. Since 2014 this also includes our factory in Varna, Bulgaria.

Through its well-developed distribution channel, Aliphos also commercialises other feed ingredients that have an important place in animal nutrition and/or follow the new trends in animal nutrition.

Phosphorus, the essential element

Mineral elements are known to have many different functions in animal nutrition, and a range of macro- and micro-elements has been identified as essential. One of these vital elements is phosphorus, which is the second most abundant mineral in the animal body after calcium. Phosphorus plays a major metabolic role and has more physiological functions than other elements. It is, for example, involved in the development and maintenance of skeletal tissue (80% of the phosphorus is found in the bones), as well as in energy utilisation and transfer, and in the maintenance of osmotic and acid-base balances.
The most common symptoms associated with phosphorus deficiency are: reduction in live weight gain caused by loss of appetite, leg disorders, reduced hatchability, reduced fertility and vulnerability to specific diseases. An adequate supply of phosphorus in the feed is, therefore, crucial to the health and optimal production of livestock.


Versatile feed solutions

Phosphates are used to adjust the phosphorus and calcium or magnesium content of the basic feeds. They can either be incorporated in complete feed, or used as mineral supplements for the production of farm feeds or silage.

The Aliphos product range covers all of these requirements. In addition to the calcium phosphates (dicalcium, monodicalcium and monocalcium), there are also magnesium and ammonia-based phosphates in different granulation sizes. These offer a choice of phosphorus concentrations and calcium/phosphorus and magnesium/phosphorus ratios to meet virtually every feed application.

In this part you will find information on phosphorus and digestible/available phosphorus content of the different feed materials

In case of ruminants including roughages. We have also included a system which enables you to calculate the P-requirements of the different animal species, simply by filling in production parameters in an Excel sheet. In case of ruminants we have also included information on Magnesium in ruminant nutrition.

Analytical Methods

Chemical analysis is a necessity to judge the quality of feed phosphate in terms of mineral content and the content of undesirable elements.

Other analytical methods like the P-solubility are used for a first indication of the quality of a particular phosphate with subsequent methods offering additional information on its composition. In this chapter a summary of the existing analytical methods is given, the whole methods can also be downloaded.

Feed Legislation

GMP certification

The introduction of a Code of Good Practice or GMP started already in 1992 in The Netherlands. After GMP certification became obligatory, Aliphos was the first Feed Phosphate producer to apply for certification according the Dutch GMP+ system.

This code of Good Practice do include HACCP principles. The implementation of HACCP consists of 12 steps, which include the listing of possible hazards associated with each production step. After analysing, the listed hazard measurements to control identified hazards are considered and implemented. Ultimately, this system will guarantee complete feed safety.

Feed Hygiene Regulation

The objective of the European Parliament and Council regulation 183/2005 laying down requirements for feed hygiene is to ensure feed safety at all stages that may have an impact on feed and food safety. Key features of this Feed Hygiene Regulation are improved traceability throughout the feed/food chain, the implementation of HACCP (Hazard Analysis and critical Control Points) systems by feed business operators and the registration of all feed businesses.

The development of guides of good practices for the production of feed and feed materials at national or EU level is foreseen under the feed Hygiene regulation. Some countries or sectors already have such Codes of Good Practices installed.


The other key-principle of the Feed hygiene regulation is traceability. With Aliphos, traceability starts with the control of the incoming raw materials to guarantee end product quality and end product safety. During production processes and products are closely monitored according a quality system in place. End products are controlled by means of sampling outgoing products and analysing same samples. 
All deliveries, either in bulk, big bags or small bags, receive a lot number. This lot number, that includes product identification, date of production and retest date, is entered in our administrative system and coupled to customer numbers. This enables Aliphos to trace feed phosphates back to the used raw materials but at the same time it also enables us to trace products of the same lot to the customers.
