Don't feed pigs distillers grains

Pat's Note: DDGS looks bad for a different reason.
Byproducts from ethanol production exposes livestock to resistant
bacteria and antibiotics as well.
Here is an extract from Mary McKenna on the subject followed by the
article from the University of Manitoba
http://drugresistantstaph.blogspot.com/
" ?Ethanol production uses yeast to convert corn starches into
alcohol
" Bacterial contamination, usually by lactobacilli, can hijack
the process and covert the starches to unusable lactic acid instead
" To prevent that from happening, ethanol producers dose their
corn mash with antibiotics
" Because contamination is frequent and persistent, producers
use increasing amounts of antibiotics to overcome bacteria that have
become resistant
" After ethanol is extracted, the mash residue remains tainted
with those resistant bacteria and with antibiotics - including
penicillin, erythromycin and streptogramin (an analog of the human
antibiotic Synercid)
" The dried mash residue is sold to farmers as livestock feed,
exposing livestock to resistant bacteria and dosing them with
unsuspected additional antibiotics as well.
If there is any good news in this, it is that (according to the IATP),
some of the faltering ethanol industry is aware of the problem and
working on it, with about 45% of plants now working on non-antibiotic
alternatives. The bad news is that 55% - more than 90 of the 170
ethanol facilities in the United States - are not.

Swine Producers Advised to Not Push DDGS Use Too High

University News for August 27, 2009
The University of Manitoba reports dried distillers grains with
solubles have a role to play in helping reduce the cost of swine
rations but producers need to be careful not to push inclusion rates
too high.
The year's abnormal growing conditions are expected to result in a
higher use of dried distillers grains with solubles, a byproduct of
ethanol production, in livestock rations.
Dr. Martin Nyachoti, an animal science professor with the University
of Manitoba's Faculty of Agricultural and Food Sciences, says
depending on the price of other feed ingredients there's every
indication using DDGS will reduce feed costs.
Clip-Dr. Martin Nyachoti-University of Manitoba:
Generally for the growing pig you probably want to have about 10
percent no more that because you start seeing an impact in performance
of those animals.
Values as high as high as 30 percent has been suggested for sows but I
think it's probably safe to say that you need maybe 15 to 20 percent
in a sow ration.
In terms of the adjustments, DDGS has concentrated levels of various
nutrients compared to the initial cereal grain so I guess one has to
take that into account when formulating the diets so that you can
still have adequate diets without over-supplying nutrients such as
nitrogen and phosphorus which we know are not only expensive but if
you have large amounts being put into the environment it'll cause
problems.
The other thing with DDGS is that they tend to have high fibre content
so feed intake might be an issue as well to consider so how much one
is going to put into the diet might impact the amount of feed that the
pigs are able to consume.
So those are some of the considerations that I think one should be
aware of.
