“…This fact is even more evident in rabbit than in other farm animals. Although this time may seem negligible in comparison with the time needed for fattening, an improper treatment of the animals during transport can cause high economic losses to the breeders (Speer et al, 2001). Meat palatability is positively related to increased tenderness, juiciness and flavour (Love, 1994).…”

ABSTRACT:Little is known about the effect that journey duration and position on the vehicle have on the sensory aspects of meat quality in rabbits. In this study, 156 rabbits were transported by road in a commercial truck for 1 h or 7 h in one of three replicates in summer or winter. After slaughter, slices from the left side of the longissimus dorsi muscle were vacuum-packaged and chilled at -18 ºC until the sensory analysis to assess odour, tenderness, juiciness, fi brousity, greasiness, and fl avour intensity. Overall, the journey duration had a signifi cant effect (P<0.05) on tenderness, fi brousity and overall liking of the meat, being better the results of the meat samples from the short transport treatment. Season had a signifi cant effect (P<0.05) on the intensity of off-odours, being obtained the highest scores in summer transports. There was a signifi cant interaction effect (P<0.05) of journey time and season on tenderness and meat odour. Therefore, meat from short journeys in summer was the most tender, and meat from long journeys in winter was the toughest. The position on the truck (in multi-layered cages) do not infl uence sensory meat quality. Therefore, rabbit sensory meat quality can be affected by transport time.

“…S Food and Drug Administration, 1994). Immunosuppression after transportation predisposes calves to developing bovine respiratory disease (BRD), which commonly occurs in the first 45 d of arrival and is associated with 65 to 80% morbidity and 35 to 55% mortality (Cernicchiaro et al, 2012;Edwards, 1996;Speer et al, 2001). Bovine respiratory disease is estimated to cost the beef industry US$500 million annually (Miles, 2009).…”

Transportation stress can result in significant economic losses to producers due to decreased animal productivity and increased medication costs associated with sickness such as bovine respiratory disease (BRD). Meloxicam (MEL) provides pain relief and anti-inflammatory effects in cattle for several days after a single oral treatment. Our hypothesis was that MEL administration before shipping would reduce the impact of long-distance transportation on circulating physiological biomarkers of stress and inflammation in beef steers. Ninety-seven beef steers were blood sampled for baseline biomarker determination and then randomly assigned to receive either 1 mg/kg MEL (n = 49) or a placebo (CONT; n = 48) per os before a 1,316-km transportation event lasting approximately 16 h. Calves were then blood sampled on arrival and 5 d later. Changes in the hemogram, circulating plasma proteins, total carbon dioxide (TCO 2 ), fibrinogen, substance P (SP), cortisol, haptoglobin (Hp)-matrix metalloproteinase-9 (MMP-9) complexes, and tumor necrosis factor α (TNFα) between treatments over time were compared using a mixed effects model with statistical significance designated as P < 0.05. Analysis of covariance was conducted to assess the relationship between circulating MEL concentrations and biomarker changes over time. An increase in neutrophil, platelet, monocyte, white blood cell, and red blood cell counts occurred after transportation (P < 0.0001) and a decrease in lymphocyte count were observed (P < 0.0001). Meloxicam treatment reduced the stress-induced neutrophilia (P = 0.0072) and circulating monocyte count (P = 0.013) on arrival. Mean corpuscle hemoglobin (P = 0.05), mean corpuscle volume (P = 0.05), and lymphocyte count (P = 0.05) were also greater in the CONT calves compared with MEL calves after transportation. Furthermore, Hp-MMP-9 complexes, TCO 2 , TNFα, plasma proteins, and SP increased and cortisol decreased after shipping (P < 0.01). Meloxicam treatment tended to reduce serum cortisol concentrations (P = 0.08) and there was evidence of a time × treatment interaction (P = 0.04). An inverse relationship between plasma MEL concentrations and circulation cortisol concentrations (P = 0.002) and neutrophil (P = 0.04) and basophil counts (P = 0.03) was also observed. The results suggest that MEL administration may reduce the impact of long-distance transportation on circulating physiological biomarkers of stress and inflammation in beef calves.

“…This could be due to the fact that more time was needed for the effect of the vitamin to be manifested following their administration since it was given shortly before loading. Further studies may be required to elucidate the effect of AA on loading exercise, which is an important component of transportation as observed by Speer et al (2001) and Tarrant and Grandin (2000), who also characterized the transport process as beginning with the assembly and including loading. The RT values recorded during the journey demonstrated clearly that transportation increased significantly the values of RT in both the experimental and control groups of transported pigs.…”

“…This is important because pigs are often transported to areas located far outside where they are produced for many economic purposes as reported by Giovagnoli et al (2002). A colossal loss both in quantity and quality of meat, high morbidity and mortality has been observed in transported animals (Ayo et al, 1996;Speer et al 2001;Vecerek et al, 2006). Thus, the administration of AA to pigs over a long distance and across different geographical zones for many hours may result in minimal loss in pigs if they are administered with AA prior to commencement of the journey.…”

Experiments were performed with the aim of investigating the effect of ascorbic acid (AA) on fluctuations in rectal temperature (RT) of pigs transported by road for eight hour during the harmattan season. Seventeen pigs administered with AA at the dose of 250 mg/kg orally and individually served as experimental animals, and 12 others administered orally with sterile water were used as control animals. Values of meteorological and RT parameters were recorded concurrently using standard procedures before the journey and at 30 min., 2, 4, 6 and 8 h of the journey, 3 h post-transportation and for three consecutive days post-transportation. The overall mean value of 38.62 ± 0.12 o C obtained in experimental pigs was significantly (P < 0.05) lower than 38.92 ± 0.13 o C recorded in control pigs. In conclusion, AA ameliorates the adverse effect of 8-h road transportation during harmattan season by decreasing the RT values in experimental pigs.
