 As broilers grow very fast, especially in the
first weeks of their lives, they need correspondingly
intensive nutrition. An adequate
supply of energy and protein, for example,
combined with bulk and trace elements is
essential if healthy, rapidly growing broilers
are to ensure the profitability of the farm.
Moreover, the performance criteria relevant
to broiler fattening such as daily weight
gain, feed conversion, the feeding period
and the mortality rate need to be improved
systematically by means of optimized feeding.
This challenge can be met successfully with
the aid of BergaPur. BergaPur is a highly
concentrated phospholipid complex with
a phospholipid content of over 95 percent.
Better known as lecithin, phospholipids are
essential nutrients and activate the birds’
metabolism in a number of ways.
Fresh meat is “in”
The trend towards fresh chicken joints is
continuing in Germany. The latest assessment
by the Society for Consumer Research
(GfK) shows that the demand for fresh
joints increased by 7.8 to 58 percent in the
first half of 2010, the total amount sold to
households being 131,000 tonnes. Purchases
of frozen joints fell by twelve percent, to
just over 34,000 tonnes, compared to the
first half of 2009. Purchases of whole fresh
carcasses also increased by 5.4 percent,
whereas the demand for frozen chickens
fell by 6.6 percent.
Better digestibility
The positive effect of BergaPur on the digestibility
of feed has now been demonstrated
in numerous trials and confirmed
in practice. The addition of 0.2% BergaPur
to complete feed for broilers improved the
digestibility of crude fat by 6% and that of
crude protein, NFE and the organic substance
by 2% each. In a field trial at the
plant of a broiler integrator with an annual
production of 35 million birds, various performance
parameters were recorded before
and after the administration of BergaPur.
The results showed that the use of BergaPur
had improved feed conversion, lowered the
mortality rate and increased profitability,
measured by the European Production Efficiency
Factor (see Table 1).

Lecithin improves feed conversion
In its role as an emulsifier lecithin is also
an important link between fats and an aqueous environment, which greatly enhances
the digestibility of the fats. Lecithin enlarges the surface area of food
constituents which is open to attack and thus increases the efficacy of the digestive
enzymes. Even fat-soluble vitamins are absorbed better.
But improved digestibility is not only of
interest because of the potential nutrient deficiency at the start of lactation. On the
contrary: an additional supply of lecithin is advisable for all high-performance cattle
since rapid passage through the rumen and thus reduced digestibility of the nutrients
is a typical characteristic.
Optimized feed economy
As a result of the above saving and the
more specific use of energy from the fat it is
possible to achieve a higher production efficiency
factor in conjunction with demonstrably
better performance.
Enhanced feed quality
BergaPur supplies essential nutrients including
natural choline (33 g), natural inositol
(37 g), available phosphorus (33 g),
potassium (10 g) and essential fatty acids
(values per kg of BergaPur).
More hygiene in the henhouse
BergaPur in the feed ensures good digestion
and a better water balance in the gut
by lowering the viscosity of the chyme. In
this way the microorganisms in the litter
and thus the risk of infection are reduced.
Moreover, dry litter helps to prevent the occurrence
of breast blisters, and this in turn
greatly reduces the wastage of meat from
the carcasses.
Better carcass quality
Besides increasing the weight of the carcasses,
the better digestibility of the crude
nutrients also enhances their quality; the
proportion of lean breast meat increases
and the proportion of abdominal fat is reduced.
Conclusions
The demands on fattening feed for broilers
are considerable. With quality raw materials
and optimum feed conversion the
birds must be fattened up to the desired
final weight as quickly as possible without
a loss of carcass quality. That means
the birds have to be sturdy and that their
health must be maintained throughout the
fattening period.
The relevant trials and practical experience
show that these complex objectives can be
achieved through the use of BergaPur in
broiler feed. Combined with good management,
this creates the basis for profitable
broiler production.
