“The “long fibre” structure determines the feed intake, faecal consistency and metabolic parameters of the acid-base balance. For example, short-chopped maize silage has a significant negative impact on the health of dairy cows compared to longer maize silage.”

The feed value of the ration for ruminants comprises besides energy and nutrients also the structure effect “long fibre”, as the structure effect is to be ensured in the glandular stomach of the animals. For rearing and fattening it is important to provide an optimised feed, and here we have the advantage of flat die pelleting of bulky raw materials (such as straw, alfalfa, etc.), which maintains the physical structure of the raw components, as can clearly be seen on the photos.
The animals get a feed, produced with KAHL flat die pelleting presses, which supports the rumen development due to its “coarse” structure and a high content of “long fibres”. The percentage of the raw materials (energy, protein and structure carriers) in the pellet is determined by the respective animal performance and development.
The “long fibre” structure determines the feed intake, faecal consistency and metabolic parameters of the acid-base balance. For example, short-chopped maize silage has a significant negative impact on the health of dairy cows compared to longer maize silage. In addition to an increase of abomasal displacements, a body cell destabilising effect could be demonstrated via the significantly higher activities of AST (aspartate aminotransferase, a liver enzyme) in the blood serum of cows fed on short maize silage. This corresponds to the experience of the practical livestock management.
Pathophysiologically the negative influence of“short” maize silage is effected via a shift in the acidbase balance towards an acidotic metabolism. The preservation of the structure in the feed pelleted with the flat die press significantly contributes to an improvement of the animal performance and animal health.
At present Amandus Kahl erects a major plant for the production of special feed in the United Arab Emirates, for example.
Kahl also supply a concentrate factory with a capacity of 40 t/h to Saudi Arabia. This feed is used above all in cattle, sheep and goat farming. The special feature of this plant is the fact that apart from normal feed for ruminants complete feed can be produced which includes both traditional grain components and long-fibre components, such as alfalfa. Due to the special technology of Amandus Kahl it is possible to largely maintain the long fibres in the pellets. This is a huge benefit to the health of the animals.
In Egypt, a plant is being built with a capacity of 35 t/h which produces concentrate feed for cattle. The customer is one of the largest grain traders and processors in the country.
