Regionally produced protein with built-in feed safetyThe raw material used for ExPro iscarefully selected, regionally grown,doublezero rapeseed. LCA (LifeCycle Analysis) in combination with our feed safety programme
ensures that ExPro has minimalenvironmental impact and a highdegree of feed safety.
KARLSHAMN
Protein nutritionLocally produced forage usually sup-plies the base of the dairy cow’s proteinsupply. The major part of these feedproteins is metabolised to ammonia which may be utilized by rumenmicrobes to form microbial protein.Good roughage in combination with aconcentrated, grain-based feed may very well satisfy the dairy cow’s need forenergy and proteins during mid to latelactation.
During early lactation and high-yield-ing period, however, the cow needs aconcentrate containing an undegradableprotein rich in essential amino acids. Among the most important aminoacids are lysine and methionine. Theprotein must have a high degree of rumen stability (i.e., it must be rumenprotected, or have a low EPD -Effective Protein Degradation value), toensure that most of the amino acidsreach the intestines where they form
precursous to milk protein and bloodglucose.
Rapeseed protein is rich in the mostimportant amino acids. These are natu-rally metabolised to ammonia in thecow’s rumen, thus resulting in a low degree of utilization. Karlshamns ABhas therefore developed the ExProprocess to produce a high-performanceprotein for ruminants - i.e. a product with higher efficiency than regular rape-
seed meal or soybean meal.
Feeding effects of ExPro and the feedfat AkoFeed on a high-yielding cow areillustrated by the diagram to the right.

Negative
energy balance
Locally produced forage, good-quality silage and regular concentrate based on grain and soybean meal, for example, will give the cow sufficient energy and protein for a milk production up to 30 kg. Yields higher than that require nutritional supplements in the form of undegradable protein such as ExPro,a bypass protein not metabolised in the rumen, along with AkoFeed rumen protected fat.

ExPro productionThe ExPro protein is produced in apatented process. After extraction of
the rapeseed oil, the rapeseed proteinundergoes heat treatment to adjust itsprotein structure - the result being aprotein that is less degradable in thecow’s rumen without any negativeeffects on its metabolizable propertiesin the intestines. In vitro studies haveestablished the protein’s rumen degra-dation rate (EPD%) at 35%, whichmeans that 65% of the high-gradeprotein’s amino acids bypass the
rumen and may thus be utilized inthe small intestine instead.

A comparison between ExPro, soybean meal and rapeseed meal. The table shows ExPro to have a higher AAT content (absorbable
amino acids) in the intestines than soybean or rapeseed meal.
The production plant where ExPro meal is processed. The feed protein is transported through a series of coiled tubes at very high speed. The ExPro treatment affects the protein’s degradability,allowing it to bypass the rumen without affecting the metabolic process in the intestines and thus treatment improves the protein utilization in ruminants. No additives are used in the produc- tion process.
Feeding studiesThe attractive taste and high-yielding effects of ExPro havebeen confirmed in practical feeding studies on several dairy herds as well as by the Swedish University of AgriculturalSciences in Uppsala (Bertilsson 1994 and Sederblad 1996).The results of these studies show ExPro to yield 2 – 3 kgmore milk per cow and day than soybean meal or rapeseed
meal, when the cow is fed the same amount of crude protein.The ExPro protein is rich in the amino acids that are
crucial for the formation of milk proteins. The diagrambelow gives an example of how many kilos of ExPro dry
matter, soybean meal or rapeseed meal must be fed tocover the required supplementation of lysine and methion-ine, assuming an energy balance needed for a 30 kg milk yield (calculations according to Rolf Spörndly SLU 2002).
Recommendations
The high effect of the ExPro protein on ruminantsimproves conditions for a high production of milk withnormal contents of fat and protein, without excess supple-mentation of crude protein.
We recommend up to 25% ExPro in concentrate forcattle, or up to approximately 4 kg per cow and day.
Summary ExProq Regionally produced bypass protein for ruminants
q
Promotes higher milk productionq Gives normal contents of fat and protein in the milk
q Makes it possible to decrease the protein content of cattle feed, and thus also to reduce its environ-mental impact.
As is shown in the table below, theExPro meal has a higher protein value
than soybean meal despite the latter’shigher content of crude protein.
