Effect of supplemental feeding with whole triticaleand processedtriticale on the growth, feed conversion, fat content,
and fillet yield of 4-year-old carp was studied under semi-intensive pond farming conditions. The trial was conducted in 83-
day-experiment in duplicate experimental ponds. Fish fed pressed or ground triticale reached significantly (P<0.05) higher
mean individual weight gain (IWG 1.00 and 0.95 kgind-1, respectively) and specific growth rate (SGR 0.70 and 0.68% d-1,
respectively) than that of carp fed wholetriticale (IWG 0.86 kgind-1 and SGR 0.61%d-1).Processed filet yield with skin did not
significantly differ between groups fed processedand wholetriticale (44.33 and 44.78%, respectively). We found moderate
positive correlation (Spearman's ρ test;r2= 0.38) between fillet yield and correlation (r2= 0.11)between fillet yield and
standard body length. Significantly (P<0.05) lower mean values of IWG (0.65 kgind-1), SGR (0.49%d-1), fat content (4.6%),
and fillet yield (41.9%) were observed in a group of fish dependent only on natural zooplankton. Common carp is able to
better utilize pressed and ground triticale compared to whole triticale, which was indicated by the decreased FCR of14.1% and
9.5%, respectively.
