What is the
precise function of acidifying feed and adding probiotics? Experiments carried
out in suggest that, in experimental situations at least, these treatments control pathogenic bacteria first, and improve production
as a side-effect. Will it catch on in practice?
Making a combined
culture of bacterial species for use as a probiotic may improve animal
performance more than a single species alone. However, understanding of
inhibition and synergy is required to make an effective combination.
Consumers
have a preference form naturally well-pigmented egg yolks. The higher values
can only be reached by red pigments; Astaxanthin is an option, derived from a
natural source with health benefits too.
The use of
feed additives containing live micro-organisms and/or their metabolites to
improve the efficiency of production in ruminants has increased in response to
demands for using more “natural” growth-promoting substances. More research is
helping to realise potential applications of these additives in ruminant
nutrition.
Phytomolecules
added to feed may not produce their effects on growth and productivity via the
same mode of action as once thought. Research has allowed us to revise our
thinking, and to take a more
integrated approach to the use of plant extracts, combining their mode of
action with those of other AGP (Antibiotic Growth Promoter)-alternatives on the
market.
For some
time the European Probiotic Association has been actively promoting the use of
these feed additives. A French oriented organisation, the group now wants to
become more European. One of their aims is to phase out quackery.
In this blog I want to touch on the area of probiotics
a little bit more. The concept of probiotics and the use of these products as
feed additives has been developing since the late 1970's, but has become more
popular in animal feed since the ban of in-feed antibiotics from January 1,
2006.
Irish scientists report that a combination of five
probiotic strains may reduce food poisoning by salmonella, if results of their
pig study can be translated to humans.
The EU ban and possible ban on AGPs in the United States is expected to
boost the growth potential of the European animal feed probiotics market in the
next five years, according to a new report.
