PT journal article

AB Two studies were designed to test the effects of stunning method and time interval between stunning and exsanguination on blood splashing in pork muscle. In study I, 82 market weight barrows and gilts were assigned randomly to one of two treatments using captive bolt (CB) stunning with either a short (S; 18.5 +/-11.1 s) or a delayed (D; 144.7 +/- 36.8 s) time interval to exsanguination. More blood splashing occured in the D group than in the S group. In study II, 48 barrows and gilts were assigned randomly to one of four treatment combinations using either CB or electric (E) stunning with time intervals of either S (8.7 +/- 3.5 s) or D (96.0 +/- 19.1 s) before exsanguination. Sex or side of carcass did not affect blood splashing. Carcasses in the CB-D group had more blood splashing than muscles from the other treatment groups. Blood splashing were similar for the CB-S, E-S and E-D groups.
