| Summary: | The current study was aimed to examine the effect of partial or complete
replacement of fishmeal (FM) with fermented soybean meal (FSBM) on growth
performance, fecal composition, and meat quality in broiler chickens. A total
number of 240 one-day-old broiler chicks were randomly allotted into four
dietary treatments with six replications and ten birds per one pen. Dietary
treatments were followed as; 1) Diet incorporated with 4% FM without FSBM
(Control), 2) Diet incorporated with 3% FM and 2% FSBM (FSBM2), 3) Diet
incorporated with 2% FM and 3% FSBM (FSBM3) and 4) Diet incorporated with 4%
FSBM without FM (FSBM4). Body weight and feed intake were recorded weekly for 35
days of the experimental period. Moreover, fecal samples were collected to
evaluate moisture, ash, nitrogen, calcium and phosphorus content on day 21
post-hatch. On day 35, two birds were sacrificed from each pen to measure meat
quality parameters and visceral organ weights. Results revealed that, no dietary
treatment effect (p > 0.05) was observed either in both
body weight or average daily gain of broilers within the entire experimental
period while broilers fed FSBM2 increased (p < 0.05)
average daily feed intake by 10.07% whereas FSBM4 improved (p
< 0.05) feed efficiency ratio by 8.45% compared to birds fed other
dietary treatments on day 7 post-hatch. Besides, birds fed FSBM3 obtained the
improved (p < 0.05) feed conversion ratio over the birds
fed control diet by 7.51% from hatch to day 35 post-hatch (1.60 vs. 1.73).
Nevertheless, no difference (p > 0.05) was detected on
visceral organ weight, proximate composition and physicochemical characteristics
of meat while broilers offered FSBM4 obtained the lowest (p
< 0.05) calcium and phosphorous in faces (2.27% and 1.21% respectively)
over those offered control feed and other FSBM treatments. In conclusion, FSBM
would be a better replacement for ousting FM partially or completely in broiler
diet as it did not impair the growth performance and meat quality while reducing
the calcium and phosphorous excretion in broilers for 35 days post-hatch. |
