“…Os valores médios do PCE foram menores que os encontrados por CHEVILLON (1994), GUISE et al (1995) e LYNCH et al (2004. Essas diferenças podem ser atribuídas aos diferentes procedimentos aos quais os suínos foram submetidos durante o manejo pré-abate, tais como o tempo de jejum, a duração do transporte, o descanso e o sistema de alimentação).…”

RESUMO O objetivo deste trabalho foi avaliar os efeitos do tempo de jejum (9, 12, 15 e 18 horas) dos animais na granja (TJG) e da posição na carroceria do caminhão (PBO) durante o transporte da granja ao frigorífico sobre: a perda de peso corporal (PPC), o peso do estômago cheio (PEC) e vazio (PEV), o peso do conteúdo estomacal (PCE) e o escore de lesão na mucosa esofágica-gástrica (ELG ABSTRACT The objective of this study was to evaluate the effect of fasting time period (9, 12, 15 and 18 hours) at the farm (TJG) and the pig's position in the lorry's livestock compartment (PBO) during the transport from the farm to the processing plant on: body weight loss (PPC), weight of stomach (full= PEC and empty= PEV), weight of stomach contents (PCE), and incidence of gastric ulcer (ELG

“…During the 30-min journey, pigs always stood and very seldom touched the floor with their nose (data not shown). The pigs' standing behaviour has been reported during short journeys in a number of previous studies (Lambooij 1988;Bradshaw et al 1996;Guise et al 1997), and can be explained either by the lack of sufficient time to lie down or by the uncomfortable travel conditions (i.e., high amount of vibrations), which prevented pigs from lying down. The standing position and the scarce exploratory behaviour seemed to have prevented the contamination of pigs' body or mouth with the faeces present on the vehicle floor.…”

“…The enhanced hunger would have led to an increased water intake after 24 h of fasting. This is supported by the fact that pellet feeding has been reported to reduce feed intake (Fekete et al 1983), and to cause a faster gastric emptying (Gregory et al 1990;Guise et al 1995).…”

“…Indeed, fasting pigs before slaughter reduces the volume of stomach contents at evisceration, preventing the release and spread of microbial contamination (e.g., Salmonella) through the spillage of viscera contents due to inadvertent puncture during the carcass dressing process (Berends et al 1996;Miller et al 1997). However, industry reports and some studies have revealed a high variability in stomach weights at slaughter, even among pigs that were subjected to fasting before slaughter (Guise et al 1995;Turgeon 2003). According to Guise et al (1995), smaller feed particle size and pelleting may increase gastric emptying rates in pigs.…”

Gregory et al (1990) also showed that feeding finely ground feed favoured gastric emptying to the same extent as liquid feeding.…”

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...
