摘要
The effect of two different lairage times on meat quality was investigated in pigs with different halothane genotype previously submitted to controlled pre-slaughter treatments. One hundred and ninety nine Italian heavy pigs were loaded by ramp or lift and transported unmixed for 1 h to the abattoir at a stocking density of either 0.6 m2 per 100 kg pigs. After unloading, an equal number of animals within each previous treatment was held in lairage for 2 h or overnight (22 h) before slaughter. Carcass and meat quality and incidence of skin damage were evaluated. Longer lairage did not negatively affect carcass traits and reduced the incidence of PSE meat without increased DFD occurrence. It also seriously increased the amount of skin damage due to fighting, resulting in long fasting. Pre-slaughter treatments and halothane genotype showed a negligible effect on the response to the resting time.

在先前提交给受控屠宰前处理的不同氟烷基因型的猪中研究了两种不同的刈割时间对肉质的影响。通过斜坡或升降机装载99只意大利重型猪,并以每100kg猪0.6m sup 2 / sup的放养密度未混合1小时运输到屠宰场。卸载后,将每次先前处理中的相同数量的动物在屠宰前保持2小时或过夜(22小时)。评估了胴体和肉质以及皮肤损伤的发生率。较长的粪便不会对胴体性状产生负面影响,并且在不增加DFD发生的情况下降低PSE肉的发病率。它还严重增加因战斗造成的皮肤损伤量,导致长时间禁食。屠宰前处理和氟烷基因型对休息时间的响应显示出可忽略的影响。
