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.

The objective of this study was to investigate the physicochemical and sensory attributes of scalded (SBC) and non-scalded (NSBC) broiler chicken breast meat. Ten carcasses from each type of chicken were randomly selected from the processing line of a commercial broiler processing plant. After dissecting the breast meat, physiochemical parameters such as pH, color, cooking loss, and proximate composition and sensory characteristics were examined. SBC contained higher protein but a lower fat content in breast meat compared to NSBC (p < 0.05). CIE L*, CIE a*, and CIE b* values of breast meat have not differed (p > 0.05) between NSBC and SBC. Higher pH values were shown by NSBC (p < 0.05) and no difference in cooking loss of breast meat from NSBC and SBC was observed (p > 0.05). Results of the sensory analysis showed a difference (p < 0.05) in the overall acceptability of breast meat between SBC and NSBC. Further studies are suggested to compare the levels of taste active compounds between SBC and NSBC.

The objective of this study was to investigate the effect of exogenous protease supplementation in dietsformulated with poultry by-product meal on growth performance, small intestine magnitudes, and meat physiochemicalcharacters in broiler chickens from 21 to 35 days post-hatch. A total of 120, one-day-old "Arbor Acres Plus" broiler chickens(male: female - 50:50) were allocated one of two dietary treatments to give six replicates and ten birds per cage. Two dietarytreatments included a control diet (CON) and a diet supplemented with protease (CON+Pro). At day 35, body weight andfeed intakes were measured to calculate the feed conversion ratio for the entire experiment period. Two birds from each penwere euthanized to measure the relative lengths and relative weights of three small intestine sections and meat samples werecollected for physiochemical characteristic analyses at 35 days post-hatch. Exogenous protease supplementation did notinfluence (P>0.05) growth performance but showed a tendency to improve FCR (P=0.082). Protease supplementation showed a tendency to reduce proximal small intestine length (P=0.091). Broilers offered dietary treatments influenced minced meatcolor where protease supplementation resulted in lower CIE b* (P<0.001) colorimetric value for yellowness and showed a significant trend (P=0.059) on reducing meat redness CIE a*. In conclusion, the addition of exogenous protease to a broilerdiet formulated with poultry by-product meal did not affect the growth performance, small intestine magnitudes, and meatphysiochemical parameters (except CIE b*) in broiler chickens.
