Resumo
This study aimed to evaluate growth
performance and economic viability of
tambaqui fed different levels of coconut husk
meal (0;25;50 and 100). Thus, a 60-day feeding
trial was performed to evaluate the effect of
dietary graded levels of coconut husk meal on
growth performance of tambaqui (Colossoma
macropomum) and economic viability. One
hundred and twenty tambaqui fingerlings with
7.71±0.17g were randomly assigned to 24 150Laquaria
in a completely randomized
experimental design with four treatments and
six replication. Diets were formulated to contain
the same content of protein (26% CP),
digestible energy (3200kcal DE/kg diet) and
crude fiber (8.51%) differing only on the
coconut husk meal replacement levels which
were 0% (control diet), 25, 50 and 100%.
Although no effect of coconut husk meal
inclusion were observed for daily weight gain,
daily feed intake, feed conversion ratio, specific
growth rate, protein efficiency ratio and fillet
yield, a negative and positive linear regression
was significant for hepatossomatic and fat
visceral indexes, respectively. The use of
coconut husk meal in diets for tambaqui did not
affect growth performance and carcass quality
parameters. However, it is recommended the
replacement of soybean meal to coconut husk
meal up to 25% based on the economic
evaluation of the diets.
