Abslract:
Flavomycin
as
feed additive
was
maxed with basal feedstuff
to
form
control group feedstuff and the added level
was
O.
08
glkg.
Four kinds of feed additive , which were Chinese herbal medicine 1 , Chinese herbal medicine n , syn-
biotics and compound enzymes
, were maxed with basal feedstuff separately
to
form
trial group feedstuffs. The added lev-
els of them were 15
glkg
、
20
glkg
、
O.
2
glkg
and
o.
6
glkg
respectively. The experimental Macrobrachium Nipponense in-
dividuals were cultured in concrete tank for
40
d feeded with the five kinds of feedstuffs. Then , the activities of amylase ,
tηptase
and pepsin in the stomach and the hepatopancreas , as well as the activity of intestine protease , and the relative
weight gain rate were investigated. One-way
ANOV
A shown that feed additives of trial groups had significant effects
on
the activities of digestive enzymes in the stomach and the hepatopancreas
(pepsin
, tryptase) and on the relative weight
gain rate(
P <
O.
05)
, however ,
no
significant differences were found in activities of the intestine protease , as well as the
hepatopancreas amylase (
P >
O.
05).
The experiment shown that the relative weight gain rate and most of the digestive
enzymes activity items of flavomycin group were significantly lower than that ones of other groups respectively
, except
pepsin in stomach of compound enzymes group
, as well as
t
巧
ptase
and amylase in stomach of Chinese herbal medicine
n group. The relative weight gain rates of Chinese herbal medicine 1 , Chinese herbal medicine n, compound en-
zymes and synbiotics group were higher than that one of flavomycin group
by
13. 10% ,
16.53
'3毛，
22.07%
and 32.

respectively.
So
it was concluded that the feedstuffes of the four groups can be digested and absorbed more efficiently
than the feedstuff of flavomycin group.
