The effects of season and post-transport rest on alpaca (Vicunga pacos) meat quality
The effects of season (summer, autumn, winter and spring) and post-transportation rest on alpaca meat quality were investigated in 160 castrated male alpacas (23 ± 1 month of age) over a 12 month period. Twice per season, animals were randomly allocated to consignment groups of 20, transported 4 h t...

| description | The effects of season (summer, autumn, winter and spring) and post-transportation rest on alpaca meat quality were investigated in 160 castrated male alpacas (23 ± 1 month of age) over a 12 month period. Twice per season, animals were randomly allocated to consignment groups of 20, transported 4 h to slaughter and allocated to either of two treatment groups: (1) overnight lairage pre slaughter (Direct) and (2) seven day rest period with access to feed pre slaughter (Rested). At slaughter, blood was collected for the analysis of plasma cortisol and a longissimus core sample obtain pre rigor for glycogen content determination. Alpaca muscle moisture loss increased through summer and spring in the longissimus thoracics. Seasonal differences did not reflect pasture seasonality or muscle glycogen content. Resting alpacas for 7 days pre-slaughter reduced muscle glycogen content and tenderness. Drip loss and purge was greater for rested animals indicating that resting alpacas post transport is not advantageous to alpaca meat quality. |
