Abstract :
The nutritive value of processed meat solubles,
Protamino Aqua, a by-product from slaughterhouses, was examined in a growth
trial with juvenile tiger shrimp Penaeus monodon. Experimental diets were
formulated to contain processed meat solubles and/or squid meal as a partial
replacement of fish meal. Dietary treatments consisted of diets (1) 5%
processed meat solubles, no squid meal; (2) 2% processed meat solubles and
3% squid meal; (3) 5% squid meal, no meat solubles; (4) no meat solubles, no
squid meal (control) and (5) commercial shrimp feed. The water stability of
the diets was tested. Diets were fed to P. monodon postlarvae, PL20, with a
mean body weight of 0.014 g, reared in tanks for 60 days. Results showed
that survival of shrimp fed the various diets did not significantly differ
(p >0.05). The only significant difference in growth performance was that
the weight gain of shrimp fed diet 3 was significantly better (p <0.05)
than that of shrimp fed the control diet. The protein efficiency ratio was
best in shrimp fed diets containing processed meat solubles and poorest in
shrimp receiving commercial feed. Protamino Aqua has a water stability
similar to that of the control diet and commercial feed and appears to be
efficiently utilized by juvenile P. monodon. The study showed that processed
slaughterhouse by-products can be a cost-effective replacement for fish meal
in tiger shrimp feeds.
