title: Sensory and objective characteristics of broiler meat from commercial broilers fed rendered spent hen meal.
abstract: The objective of the study was to determine sensory and objective characteristics of broiler breast and thigh meat from commercial broilers fed rendered spent hen meal (RSHM) from hatch to 42 d of age. Breast and thigh muscles from 90, 6-wk-old straight-run broilers (i.e., mixed male and female broilers) fed starter and grower diets consisting of either 0, 8, or 12% RSHM were evaluated for sensory characteristics, instrumental texture, and compositional profiles. The RSHM treatments had no adverse effects (P > 0.05) on juiciness, chicken flavor intensity, tenderness, or compositional profiles for the breast or thigh meats. Off-flavor scores for all treatments were above the threshold value, indicating that the RSHM imparted no off-flavors to the breast and thigh meats. Warner-Bratzler shear measurements were similar (P > 0.05) for breast meat from broilers in all treatments. No shear measurements were conducted for the thigh meat. It was concluded that RSHM can be incorporated into the diets of broilers at levels of up to 12% without causing objectionable sensory characteristics in the cooked broiler meat.
