A study confirms that the use of BergaZym P in broiler fattening optimizes feeding and greatly increases profitability.
High daily weight gains, good feed conversion
and a low loss rate: these are the
criteria that determine success or failure in
broiler fattening. That makes considerable
demands on the plant manager: besides
production technology enabling maximum
comfort for the birds and elaborate hygiene
management to prevent disease, nutrition
plays a decisive role. Feeding in keeping
with the birds’ needs and performance
is a matter of the energy, protein and fat
content of the feed, the ratio of protein to
energy and, not least, the quality of the
protein.
Enzymes for better availability of nutrients
Since poultry are not readily able to convert
some groups of nutrients, for instance certain
carbohydrate compounds, the addition
of enzymes to the feed is an important topic.
Berg+Schmidt has developed the product
BergaZym P specially for the Asian feed
industry, where an extremely high percentage
of maize and soya is used in the feed
mixtures. BergaZym P is based on a multi-
enzyme containing 1,4-β-pentosanase as
the lead enzyme, with further enzymes
such a α-amylase for better starch digestion
and a protease to aid the digestion of protein.
In two production steps, BergaZym P
is microgranulated and coated for greater
temperature resistance during pelletizing
and better pH stability in the animal’s intestinal
tract. This ensures that the enzymes
required for digestion can take effect in an optimum concentration where they are
needed.
BergaZym P in practical use
In 2009 the efficacy of BergaZym P was veri-
fied in a trial conducted with the King Saud
University in Riyadh, Saudi Arabia, using
maize/soya rations under the conditions
usual in the region (see Table 1).

A total of 800 birds of the breed Cobb 500
were included in the trial; they were divided
into groups of equal size on a random basis.
The quantity of BergaZym P used in the
trial group was 250 g per tonne. An evaluation
of the results after 42 days of fattening
showed the final weight of the birds in the
BergaZym P group to be significantly higher
(100 g) and their feed conversion to be significantly
better (see Table 2).
It was further found that the protease contained
in BergaZym P had improved the digestibility
of the protein by 5.3% and led to
an 8% greater proportion of valuable breast
meat.

Greater profitability
A profitability calculation was carried out,
based on the results of the trials and market
conditions in Saudi Arabia (see Table 3).

The evaluation is impressive evidence that
a 5.9% higher live weight was achieved
through the use of BergaZym P. But the
calculation also shows that the cost of
BergaZym P (2,000 USD for 1,000 t of feed)
was more than set off by additional sales
proceeds of 30,474 USD. That is equivalent
to a yield of 133.46 EUR per 1,000 broilers.
Better for the environment – less risk of infection
It was also found that the addition of
BergaZym P had reduced the water content of
the birds’ excrement by 2 percentage points,
from 68 to 66 %. The water consumption of
a broiler in the BergaZym group fell by 650 g.
The reduced moisture content of the litter
restricts the growth of undesirable microorganisms such as
coccidia and thus reduces the risk of infection.
BergaZym P also lowers the viscosity in the
intestinal tract, with the result that more
water is available to the organism for digestion
and the animal therefore needs less
extra water.
A fast-growing market
Never before has so much chicken meat been produced in Germany: at around 754,000 t the
weight of broilers slaughtered increased last year by nearly 6 % as compared to 2008. That means
production has almost doubled in the last ten years. At the same time imports increased by nearly
6.8 % to 555,500 t, while exports rose by more than 10% to just under 432,000 t. The annual per
capita consumption in Germany was 10.7 kg.
USA, the world champion
As far as the annual per capita consumption of poultry meat is concerned, the USA is the unchallenged
world champion: Americans consume over 45 kg of chicken and turkey meat, followed by
the Brazilians with 36 kg. In Germany, on the other hand, there still seems to be enough market
potential. Only just under 19 kg of poultry meat are consumed there each year, albeit with an
upward trend: consumption increased by 300 g compared to 2008.
