Overview:
The growth weight, feed demand rate, survival rate,
nitrogen, phosphor, and excretion rate of dry matter
in excrement were compared between a test group and a
control group. The test group was fed with low protein
and low phosphor feed added with commercial amino acid
and phytase (16 % CP, 0.3 % nonphytin phosphorus) and
the control group with feed equivalent to Japanese Feed
Standard (18 % CP, 0.4 % nonphytin phosphorus).
No difference was observed for the growth weight, feed
demand rate, and survival rate, but the excretion of
nitrogen and phosphor of the test group was
significantly small. The quantity of dry matters
in excrement of the test group was somewhat smaller,
but there was no appreciable difference. Based on the
above results, by feeding meat chickens with the low
protein and low phosphor feed added with commercial
amino acid and phytase, it was shown that nitrogen and
phosphor excretion was reduced together and that the
quantity of dry matters in excrement tended to be
reduced.
In addition, the feed cost per bird increased by
4.2 to 8.4 yen by adding amino acid and phytase.
