| Summary: | 1.25 h PM compared to controls, ES did not affect calpastatin 1.25 h PM whereas there was no such difference over PM time 450 mA. The remaining 36 birds of each type were used as a lower muscle pH at 0.25 h and 1.25 h PM and higher Rvalues activity in either broilers or ducks; however, the aging period time whereas that of the ducks did not. In All data were analyzed within species. ES treated ducks had at 0.25 h PM compared to controls. ES treated broilers had a avian muscles comprised primarily of either red or white broilers, ES decreased shear values at 1.25 h PM compared to calpastafin activity, and tenderness in anatomically similar calpastatin activity of the broilers did decrease over the calpastatin activity, shear value, and percent cook loss. controls. However, in the duck muscle there was no difference in shear values due to ES at any time PM, There ducks were treated with postmortem ES at the neck in a 1% electrical stimulation (ES) on rigor mortis development, exhibited increased myofibrillar fragmentation at 0.25 h and had no effect in the ducks. These results suggest that the harvested from the carcasses after 0.25 h, 1.25 h, and 24 h in the duck muscle. Cook loss was lower for ES-treated length (SL), gravimetric fragmentation index (GFI), lower muscle pH at 1.25 h and higher R-values at 0.25 h and muscle fibers. Thirty-six broilers and thirty-six AUte Pekin NaCl solution for 2 sec on I sec off for a total of 15 sec at non-stimulated controls. Both Pectoratis muscles were of the broiler Pectoralis. postmortem (PM) and analyzed for pH, R-value, sarcomere red fibers of the duck Pectoralis have less potential for rigor mortis acceleration due to ES than do the white fibers shortening at 1.25 h PM with ES. ES-treated broilers This study was conducted to evaluate the effects of time PM whereas the duck had an increase in sarcomere was no effect on SL due to ES in the broiler muscle at any |
