“…This scenario, in addition to reducing the thermoregulation capacity of pigs, since heat dissipation through panting becomes inefficient (Nardone et al, 2010), can cause a high energy cost and result in excessive CO2 loss (Mota-Rojas et al, 2012), causing a drop in partial pressure and in the concentration of carbonic acid and hydrogen, which can increase the DOA rate (Tasse & Molento, 2019), dehydration (Machado et al, 2016) and time post-transport recovery of animals (Johnson et al, 2018).…”

This study evaluates the dynamics of heat zones in the load and its relationship with the stress of pigs during transport. Four journeys of 170 km were monitored, recording the physiological variables of 192 animals (48 per journey), namely rectal temperature (RT), body temperature (BT), respiratory rate (RR), blood lactate concentrations and salivary cortisol. Heat zones and ventilation patterns were characterized by the spatial variability of the enthalpy and the Computational Fluid Dynamics of the load. The formation of a thermal core was observed in the frontal region of the load, which extended through the lower (LD) and upper (UD) decks. Pigs transported in the LD had higher means of RR (UD = 89 and LD = 94 breaths/min), and salivary cortisol (UD = 33.84 and LD = 34.92 ng/mL). The pigs transported in the UD presented the highest mean BT (UD = 38.9 and LD = 38.1 °C) and lactate (UD = 61.63 and LD = 58.26 mg/dL). Pigs transported in the LD of the load were more susceptible to thermal stress, while pigs transported in the UD showed greater physical stress and muscle exhaustion.

“…In addition, an animal will also experience weight loss when there is a lack of food and water. Machado et al (2016) estimate the rate of body weight loss can reach 12% of the initial weight of an animal. Body weight reduction is the most important economic effect because animal trade is usually based on body weight variables (Bravo et al, 2018).…”

The process of transportation of animals from one to another area can lead to stress. Animals tend to reduce feed intake which then affects animal performance, so palatable feed is needed, with high energy content, and can speed up the body weight recovery process. This study aimed to evaluate the effect of logistic feed (mash, silage, pellet, and wafer) compared with conventional feed on physiological parameters, blood metabolite profiles, and body weight recovery of tropical sheep pasca transportation. This study used Randomized Block Design (RBD) consisting of 5 treatments and 6 replications using 30 male local sheep: P 0 = conventional feed (100% forage), P 1: Mash, P 2: Silage, P 3: Pellet, P 4: Wafer. The logistic feed has a significant effect on dry matter, crude protein and ether extract intake, blood glucose level, leukocytes lymphocyte, Neutrophil and Lymphocyte (N/L) ratio, and basophil level in sheep blood, total body weight gain, feed efficiency, and income over feed cost (P<0.05). A logistic feed can accelerate the increase in the body weight recovery process of sheep pasca transportation. Moreover, the provision of logistic feed in the form of silage resulted in the highest feed efficiency and income over feed costs.

“…Segundo Pilcher et al (2011), tempo de transporte com mais de 3 horas, são classificados como longos, enquanto na União Europeia para esta mesma classificação considera-se viagens acima de 8 horas (Brandt & Aaslyng, 2015). Em pesquisa realizada no Brasil o período de transporte para viagens de até 2,99 horas foi considerado como extra curto, entre 3 e 3,99 horas como curto, entre 4 e 7,99 horas como médio e acima de 8 horas como longo (Machado et al, 2016). Porém a mesma literatura destaca que a duração do transporte acaba por determinar aspectos negativos como privação de água e alimentos, estresse por calor e falta de oportunidade para descanso, comprometendo, portanto, o bemestar e parâmetros de qualidade de carne.…”

The pre-slaughter management of pigs, including loading, transport, unloading and resting time in the slaughterhouse can compromise animal welfare evidenced by the increased incidence of bodily injuries, skin lesions and compromised quality of carcasses and meat. The aim of this study was to assess whether the time taken to transport pigs from the production farm to the slaughterhouse influences on the bodily injuries and the skin damage score of carcasses. Transports lasting 2 hours, 8 hours and 14 hours were considered. Bruises, bite marks and abrasions were considered as bodily injuries. The incidence of injuries was high in the regions of the dorsum (76.53%), hind limbs (44.34%) and neck (38.97%) of the animals, but the transport time did not influence (P > 0.05) the incidence of bodily injuries, although there was a 16.28% reduction in the presence of injuries in the region of the rear limb in the shortest travel time (P = 0.0873). Abrasions on the dorsum were higher (P < 0.031) in transport lasting 8 hours, while the score for more severe injuries increased (P = 0.077) by an average of 77.06% in the longer transport compared to transport of 2 or 8 hours. The influence of transport time on the absence or severity of the skin damage in the carcass was evidenced by the Fisher test (P < 0.0001), allowing to infer that longer journeys contribute to the increase in carcasses with a worse skin damage in carcasses.
