Introduction
With the advent of "greener", more environmentally friendly
farming practices there has been a distinct move towards the production
of more natural food stuffs for human consumption. A major aspect
of this is the inevitable trend in favour of foods produced under
more acceptable conditions, including that from animals, which have
been fed diets free from unnecessary additives.
Some
years ago, the use of hormones to promote growth in farm animals
was unilaterally banned because of fears for the consequences to
human health. The present day fears surround the widespread use
of antibiotics in animal feeds to achieve a similar end. For many
years the sub-therapeutic use of such pharmaceuticals have had the
useful effect of:
·
Controlling the bacterial population of the internal environment
of the animal, and
· Improving their growth rate and feed conversion efficiency
This
has been an economically viable method of raising animals for food,
especially under increasingly intensive conditions where the spread
of disease is easy and sub-optimal management standards are prevalent
In short, antibiotics have been a crutch for an industry under increasing
financial pressures.
Recently, there has been a growing concern over the possibilities
of antibiotics used in animal nutrition causing cross-resistance
to the generation of antibiotics intended for use in human medicine.
Sweden
was the first country to take positive action in prohibiting the
sub-therapeutic use of in-feed antibiotics. Avoparcin was banned
throughout Europe and Denmark imposed its own internal ban on antibiotic
growth promoters in broiler feeds and in feeds for growing pigs.
Now, four more growth promoters -virginiamycin, spiramycin, tylosin
and zinc bacitracin are to be banned.
The
consequences for the animal production industry are grave and various
estimates into millions of dollars have been made as to the economic
effect such moves will have. Quite simply, the industry will have
to find an alternative method of maintaining modern levels of production
and routinely controlling microbial populations -but in a way that
is consistent with the natural and "green" approach
The
answer lies in Genex.
