Analysis of
different vitamin e sources for poultry rations showed clear differences in the
transfer rate to body tissues. By comparing three different sources,
baker and his colleagues pelletier, pfeiffer and troescher oncluded that
currently used silica-based standard formulation provides the best performance
for poultry.
When forced to do so, we have no choice but
to reduce phosphorus excretion on poultry farms. Even where it is not
mandatory, economics dictates that we attempt phosphorus excretion reduction.
Research at ArkansasUniversity suggests that
we consider combining improved phosphate sources with phytase enzymes.
Lipids are one of the most important
variables in meat quality and are especially vital to meat shelf life. Studies
show that the most effective way of prolonging shelf life and maintaining
quality is to introduce antioxidant protection through the diet.
Animal
nutrition can also benefit the human population, simply by enriching feed with
the necessary nutrients. There is a real need in many countries to increase our
selenium intake and with the controversy surrounding cholesterol in eggs at
last reaching a conclusion, what better packaging is there for good human
nutrition?
Heat stress and age are common causes of
reduced egg shell quality and incur large economic losses in the Indian poultry
industry. A number of plants are known to contain high levels of metabolically
active vitamin D3. Studies have shown that under adverse conditions, these can
be useful in reducing the egg shell quality problems associated with age.
Two enzyme products used widely in the poultry industry to improve the
digestibility of wheat- and maize-based diets have been found to have additional
effects on the numbers of bacteria in the gut of broilers that can cause food
poisoning in humans.
When environmental pollution becomes a restricting factor in
livestock nutrition, there is a danger of over-compensating. In poultry
production, this could have damaging effects on welfare. There is thus a need to re-assess phosphorus requirements in
practice.
Since the European ban of most traditional
antimicrobials and growth promoters in animal feed, many alternatives have been
discovered, tested and commercialised. Safe, innovative and powerful plant
extracts can fit perfectly into today's animal husbandry and will play
important roles in the sustainable husbandry practices of the future.
The Dutch measures against Salmonella in animal feed are highly effective.
This became apparent after an analysis conducted by PDV (the Dutch Product Board
Animal Feed).
After the detection of an illegal colorant in
eggs in Ho Chi Minh City, Vietnam, egg sales dropped with 50-70%.
However, the test is not considered representative and experts are now
double checking the findings.
