title: Effects of the terminal sire type and sex on pork muscle cathepsins (B, B+L and H), cysteine proteinase inhibitors and lipolytic enzyme activities.
abstract: Pork muscle cathepsins (B, B+L, and H), cysteine proteinase inhibitors and lipolytic enzyme activities were measured in the offspring of five different genetic sire types: Danish Duroc (DU), Dutch Large White (LW(D)), English Large White (LW(E)), Belgian Landrace × Landrace (BL×LR) and Belgian Landrace (BL). Cathepsin B and B+L activities were higher for LW(E) and LW(D) sires than for BL×LR and BL. Cathepsin H activity showed an opposite evolution, being higher for BL and BL×LR sires than for DU, LW(D) and LW(E). Cysteine proteinase inhibitor activity was higher for LW(E) sires than for DU and BL. In lipolytic enzymes, BL sires had a lower acid lipase activity than DU and LW(E) sires and also a lower neutral esterase activity than LW(E) and LW(D) sires. Significant differences between sexes were found for cathepsin H activity only, being higher for females.
