“…This average weight meets the abattoir specification for maximum stomach weight (1400 g; Chevillon 1994). However, 25% of the stomachs evaluated in this study exceeded this weight and, as reported by Faucitano et al (2006), 51% had contents weighing more than 500 g (671.3 g on average), which is the recommended threshold to prevent carcass contamination at slaughter (Chevillon 1994).…”

L. 2007. Effect of feed texture, meal frequency and pre-slaughter fasting on behaviour, stomach content and carcass microbial quality in pigs. Can. J. Anim. Sci. 87: [479][480][481][482][483][484][485][486][487]. In this study, behaviour in lairage, weight and composition of stomach contents and carcass microbial contamination were studied in 96 barrows assigned to the following treatments: feed texture (FT; mash vs. pellets), meal frequency (MF; 2 vs. five meals per day) and fasting time (WT; 4, 14 and 24 h) according to a 2 × 2 × 3 factorial design. Pigs fed two meals had heavier stomach weights at slaughter than those fed five times per day (P = 0.01). An interaction was found between WT and FT (P = 0.002) for stomach weight. With respect to the contamination of the mouth, total aerobic mesophilic counts were higher than 10 4 cfu cm -2 but not significantly different between treatments. Coprophagy behaviour in lairage was not correlated with mouth contamination at slaughter. The treatment resulting in the lowest Escherichia coli counts on the thoracic area was feeding the pigs pellets five times per day followed by a 24-h fast. In contrast, the highest E. coli counts were observed in pigs fed mash five times per day followed by a 4-h fast. Comparison a posteriori of these two extreme scenarios yielded a P value of 0.03.

Effet du type de moulée, de la fréquence des repas et de la mise à jeun avant l'abattage sur le comportement, le contenu stomacal et la contamination microbienne de la carcasse chez le porc. Can. J. Anim. Sci. 87: 479-487. Dans cette étude, le comportement des animaux au repos, le contenu de l'estomac ainsi que la contamination microbiologique des carcasses ont été évalués sur 96 mâles castrés assignés aux traitements suivants : texture des aliments (FT : farine vs. cubés), la fréquence des repas (MF : 2 vs. 5 fois par jour) et le temps de jeûne (WT : 4, 14 et 24 h) selon un plan expérimental factoriel 2 × 2 × 3. Les porcs recevant deux repas par jour avaient un poids d'estomac plus élevé que ceux nourris cinq fois par jour (P = 0,01). Une interaction significative a été observée entre WT et FT (P = 0,002). La contamination de la gueule par les aérobes mésophiles totaux était supérieure à 10 4 cfu cm -2 , mais pas significativement différente entre les traitements. Le comportement coprophage pendant la période de repos n'était pas corrélé à la contamination de la gueule au moment de la saignée. Le traitement pour lequel la contamination de la région thoracique par Escherichia coli était la plus faible est celui dont les animaux étaient nourris avec de la moulée cubée, cinq fois par jour et suivi d'un jeûne de 24h. À l'inverse, l'énumération des E. coli était plus élevée pour les porcs nourris avec de la moulée non cubée, présentée cinq fois par jour et suivi d'un jeûne de 4 h. La comparaison a posteriori de ces deux scénarios renvo...

“…It is well known that pre-slaughter management influences the final quality of meat (Gispert et al 2000;Faucitano 2001;Guàrdia et al 2004Guàrdia et al , 2005. To obtain better quality and safer pork, feed withdrawal 16-24 h before slaughter is recommended (Eikelenboom et al 1991).…”

“…Overall, the pHu values obtained in this study are rather low, possibly because of the still high glycogen reserves in the muscle at slaughter allowing an extended pH fall over time. As already observed by Faucitano et al (2006), in small scale studies conducted under experimental conditions it is difficult to observe a significant depletion in muscle glycogen levels as the stress level is generally very low. Differences in pHu values between genotypes could be observed in this study.…”

“…However, during this time liveweight losses are more related to the excretion of urine and feces rather than to body tissues and consequently carcass weight is not affected (Beattie et al, 2002). Losses in carcass weight of approximately 100 g/h are reported after 24 h fasting (Chevillon, 2000) which would be equivalent to a total decrease of 1% of carcass yield after a fasting period of 24 h (Faucitano et al, 2006); however, other studies have shown that fasting times as long as 60 h did not affect carcass weight losses (Ellis, 1998;Turgeon, 2003). This discrepancy in the results can be explained by the different levels of stress imposed on pigs between studies.…”
