1997 feed trial comparing BioKyowa-C to Silver Cup

1/13/97 — We decided to place four lots of fish on Bio Kyowa-C diet and the other four lots a vitamin-boosted Silver Cup diet.

Results of six-month study:

Lot number	Diet fed	Fish/lb start	Fish/lb end	Feed conv.	Feed cost/lb gained	Daily growth
94SKJNLot-8	Silver Cup	86.10	23.70	1.62	$0.68	.008"
94SKJNLot-4	" "	78.21	25.43	1.93	$0.86	.007"

Results of six-month study on crippling: mouth, vertebral, cranial, operculum and fins were checked for crippling before and after feed trial.

Diet feed	Percent crippled before	Percent crippled after	Percent increase
Silver Cup	29%	77%	48%
Bio Kyowa-C	13.5%	21.8%	8.3%

Note: It was obvious from this feed trial that the BioKyowa-C was a much better diet for the June sucker. The only negative is the feed cost of the BioKyowa, but when the overall fish health was compromised by feeding the Silver Cup diet it is was determined that the BioKyowa was well worth the added cost.
