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.

Objective: An experiment was conducted to determine the effect of algae-based antioxidant containing Se yeast (EconomasE®) on the growth performance, visceral organ weight, meat quality, and oxidative stability of broiler chickens.Methods: Nine hundred sixty, day-old male broiler chickens (Cobb, 43.97±0.55 g) were divided into three dietary treatments and allocated into 12 deep litter pens in a completely randomized design giving 4 replicate cages for each treatment. Three dietary treatments were: i) control (CON, basal diet with sufficient nutrient), ii) vitamin E (VitE, basal diet supplemented with 100 IU VitE), and iii) Algae-based antioxidant containing Se yeast (EcoE, basal diet supplemented with 0.2% algae-based antioxidant containing Se yeast: EconomasE®). Maize soybean meal based basal diets were formulated to meet or exceed the nutrition requirement for broiler chickens. Chickens were fed ad-libitum experimental diets during the 42 days experiment period. On days 21 and 42, body weight and feed intake were measured to calculate the feed conversion ratio of the chickens. Intestine and visceral organs were measured together with meat quality and oxidative stability on days 14 and 42.Results: Chickens fed with EcoE showed improved (p<0.05) growth performance, meat quality, and higher (p<0.05) oxidative stability compared to the chicken fed on CON. Moreover, broiler chickens fed with EcoE showed similar (p<0.05) growth performance with better (p<0.05) meat quality and higher oxidative stability compared to the broiler chickens fed VitE (p<0.05).Conclusion: The algae-based antioxidant containing Se yeast can be supplemented into commercial broiler diets as a substitution of VitE while maintaining growth performance with enhancing meat quality and oxidative stability of the broiler chickens.

Purpose: There is a need to explore the use of non-conventional, locally available and cheap energy-rich ingredients to substitute corn in broiler diets as it is used mainly for human consumption in developing countries. Therefore, this study investigated the effect of partial substitution of corn with breadfruit flour (BFF) in broiler diets on growth performances and meat quality in broiler chickens.Research Method: One hundred and eighty day-old straight-run "Cobb 500" broiler chicks (45.92 ± 0.43 g) were randomly allocated into one of three dietary treatments (Corn based basal diet with no BFF [Control], Corn-substituted basal diet with 5% BFF [BFF5], and Corn-substituted basal diet with 10% BFF [BFF10]) with six replications and 10 birds per replicate. Growth parameters including body weights, average daily gain, average daily feed intake, feed conversion ratio, and organ weights and meat quality parameters were determined. Findings:The broilers fed BFF10 significantly (P < 0.05) improved the body weight, average daily weight gain, and feed efficiency of broilers for the complete experimental period (d 1-35). Further, the same diet improved (P < 0.05) the average daily feed intake of broilers for the starter period (d 1-7) compared to the control diet. Furthermore, broilers fed BFF10 had a heavier (P < 0.05) heart, liver and empty intestine than those fed BFF5. Moreover, breast meat of broilers fed BFF10 had a significant (P < 0.05) lower crude fat content and CIE a* value than that of broilers fed other diets.Originality/value: Breadfruit flour would be a suitable non-conventional energy feed source to partly substitute corn in broiler diets up to 10% with improved growth performance and meat quality in broiler chickens.
