Test included two flocks, 20 each, of Rhode Island Reds
of the same strain. Identical housing for each flock. The only
difference was flock "one" had 2% DE mixed into their feed.
Here is a bullet point summation:
Egg Production: Pre test, flock
#1, 84% flock #2 89%
Post test, flock #1 78% flock#2
85%
Exterior Quality: Thin shelled, No change
Ridged
shells, No change
Soft shell, 3 hens total no change
Carbon
shell, No change
wrinkled shell, 2 hens, improvement
overall
texture, smoother
Interior Quality: Meat spots, 2 hens, sporadic,
no change
blood spots, no change
All other interior aspects, No
change
Overall health: flock #1 a hen became sick with a crop
infection on day 37. Crop swollen and distended. Infection due to a
puncture from something, I'm not sure. We were not able to determine
what the real cause was, wire, straw, staple.....? the hen was culled
on day 52 and no replacement was made.
Droppings were much more
dry in flock #1 (DE flock). The Consumption of oyster shell that was
available to flock #1 did not change and was on par with flock #2
over the 90 day test.
Conclusion: From an economic standpoint
DE was of no measurable benefit and in fact was an additional cost to
my egg business with no quantitative return. The existing egg quality
problems, which included several hens, did not change to the point
that justifies the use of DE in the feed in order to improve upon the
problem. Flock #1 (DE flock) had no measurable increase in feed
conversion which was a hope of mine. The pre existing problems with
some of the hens eggs still exists and I will cull those hens. I will
continue to use DE as a pest control and dryer (absorbent) as needed
around the hen house and gardens.
I post this simply to share
the results of "MY" controlled DE test and not to argue the
use or non use of DE in hens feed. I did spend many hours, cracked
100's of eggs, and spent a little money in order to come to the
conclusion. "
Bio-live Yoghurt:
Some
say that bio-live yoghurt has a beneficial effect on the gut both for
humans and animals. John Seymour, a now dead farmer who wrote many
books on self sufficiency (see links page - recommended reading
section) even advocated it's use and he was not one to go along with
fads. I feed it mixed with oats to make a porridge/oatmeal mixture.
