Resting Period

Over 1900 pigs, supplied by two producers, were first delivered to an assembly yard and then transported to a commercial abattoir. Transport times were 50 min and 2 h, and resting periods at the abattoir were < 30 min, 3 h and 6 h. Times were chosen to represent normal practices in Ontario. The colour and structure of the boneless loins were as sessed subjectively 24 h postmortem. The shorter (50 min) transport time was associated with the highest (P ≤ 0.05) incidence of pale and soft/exudative loins. A longer transport time reduced the incidence of pale and soft/exudative loins; it also increased (P ≤ 0.05) the incidence of dark and firm/dry loins; particularly during winter. A resting period of < 30 min resulted in the highest (P ≤ 0.01) incidence of pale and soft/exudative loins. A 3 h resting period significantly improved (P ≤ 0.01) quality by reducing the incidence of pale loins and soft/exudative loins. Extending the resting period from 3 h to 6 h provided inconsistent improvements in quality due to interactions with season (P ≤ 0.05) and producer/management (P ≤ 0.05). Considering transport time and resting period together further highlighted the importance of resting period at the abattoir. Three h resting period always improved (P ≤ 0.05) quality regardless of transport time, season or producer. Key words: Transport, resting period, pork quality, pale, soft and exudative, DFD

Three groups, each consisting of six crossbred pigs weighing approximately 100 kg, were used to determine the effects of three preslaughter stunning methods on certain quality characteristics of the longissimus, semitendinosus and biceps femoris muscles. The three methods of stunning were captive-bolt, electric shock and oral dantrium (dantrolene sodium, a muscle relaxant) followed by captive-bolt. The three muscles were significantly different to each other in some of the quality traits, but the responses to treatments were similar in the three muscles. Without dantrium, captive-bolt stunning resulted in reduced muscle pH at 45 min postmortem and a greater water exudation in muscles at either 1 h or 24 h postmortem compared to electrically stunned pigs. Dantrium treatment followed by captive-bolt stunning eliminated these differences. Key words: Pigs, PSE, stunning, muscle relaxant, dantrolene

Development of tourism and transport infrastructure closely related and interwoven process. Tourism as mass phenomenon was a result of nascence and development of transport. It’s admitted fact. However emergence of transport area as direction of social-geographic research happened in the middle of XIX century. Before that transport infrastructure just had been forming, evolving and making direct influence on the world’s travelling at all. Main stages of conception and development of transport infrastructure of Europe in the context of territorial spreading of tourism are considered in this article.

Abstract Forthcoming revisions to Canadian Transport regulations indicate un-weaned and weaned calves can be transported a maximum of 12 and 36 h, respectively, before an 8 h rest is required. The aim of this study was to assess the effect of rest duration after 12 and 36 h of transport on physiological and behavioral indicators of welfare in 7–8 mo old beef calves. Three hundred and twenty weaned calves (258 ± 23.9 kg BW) were randomly assigned to a 2 × 4 factorial design: 12 and 36 h of transport; and 0 (R0), 4 (R4), 8 (R8), and 12 (R12) h of rest. After the resting period animals were transported for an additional 4 h. A subset of 12 animals/treatment were sampled for non-esterified fatty acids (NEFA), haptoglobin and lactate concentrations prior to, and after the first and the 4 h transport, and 7 h, 2 and 28 d after the 4 h transport. Standing and lying behavior was assessed for 14 d after transport. Data was analyzed using the GLIMMIX procedure of SAS, where transport, and time nested within rest period were fixed effects and animal was a random effect. NEFA concentrations were greater (P &lt; 0.01) in 12-R4 than 12-R8 and 12-R12 calves, while 36-R0 calves had greater (P ≤ 0.05) NEFA concentrations than 36-R4, 36-R8 and 36-R12 calves after the 4 h transport. Haptoglobin concentrations were greater (P &lt; 0.01) in 36 than 12 h calves. No differences (P &gt; 0.10) were observed for lactate. The day after transport, 36-R8 calves spent more (P &lt; 0.01) time lying than 12-R8 calves. Overall, physiological indicators were greater in calves transported for 36 than 12 h, while no differences were observed between rest stops with the exception of NEFA, where overall concentrations were greater after shorter than longer rest periods.

Fat thickness (3rd–4th last rib) was weakly correlated with subjective pork structure score (R2 = 1.0%) and marbling score (R2 = 1.6%) in 399 boneless pork backs sampled from commercial processing plants. Pork colour and structure scores (R2 = 5.9 and 11.1%) were more highly correlated with marbling score than carcass fat and muscle depths (R2 = < 2.0%). Pork backs that had structure scores of 1 and 2 (extreme to slight soft and exudative pork) tended to have low amounts of marbling (traces or less). A second trial with 311 pork backs also indicated that higher marbling scores were associated with lower frequencies of pale, soft and exudative pork. Key words: Pork quality, marbling, PSE

The influence of pretest hand-resting time and induction time on kinesthetic aftereffect was determined for 22 males and females. Aftereffect was assessed with the apparatus of Koehler and Dinnerstein (1947). Three separate tests of aftereffect were administered. Each was preceded by either a 10-, 20-, or 30-min. hand-resting period. Significant differences in aftereffect were not found between pretest conditions. Scores were also determined for varying induction times at each pretest condition. Induction periods totaling 90-, 180-, and 300-sec. were used. Aftereffect was significantly less pronounced following 90 than 180 sec. of induction for the 10- and 20-min. pretest conditions but was the same following 90, 180, and 300 sec. of induction for the 30-min. condition. Results indicated that less than 300 sec. of induction could be used regardless of the duration of the pretest period. However, because the internal validity of the 180-sec. score was significantly better than the 90-sec. score, it was concluded that at least 180 sec. of induction were needed.

Canada Data

This is an observational study to investigate slaughter cattle transportation conditions in Canada. Data collected include: length of time in transit; temperature variation; season; weather transport conditions; cattle weight; sex and whether sexes were separated on mixed loads; number of lots and whether lots were separated; cattle unloading speed; cattle handling score; trucker training and experience hauling cattle; ventilation; and condition of cattle at arrival. Information was collected on approximately 50 000 animals transported by 1363 trucks. All but 0.2% of trucks arrived within the 52 h allowable transport time before unloading required for rest, feed, and water. Most trucks (85.7%) were from within 8 h of the plant. Trucks surveyed were at or above the recommended space allowance 49% of the time. There were five non-ambulatory (unable to walk off the truck with or without assistance) or dead, 79 lame, and four animals that needed assistance of the 49 959 animals observed (0.4, 4.8 and 0.2%, respectively, of the trucks surveyed). However, these concerns were not necessarily a result of transportation, as animal health at loading was unknown. There were very few visible animal welfare concerns associated with the transportation of slaughter cattle in the population sampled. Key words: Cattle, transport, welfare, beef

The aim of this study was to investigate the effect of pre-slaughter handling on the occurrence of PSE (Pale, Soft, and Exudative) meat in swine slaughtered at a commercial slaughterhouse located in the metropolitan region of Dourados, Mato Grosso do Sul, Brazil. Based on the database (n=1,832 carcasses), it was possible to apply the integrated multivariate analysis for the purpose of identifying, among the selected variables, those of greatest relevance to this study. Results of the Principal Component Analysis showed that the first five components explained 89.28% of total variance. In the Factor Analysis, the first factor represented the thermal stress and fatiguing conditions for swine during pre-slaughter handling. In general, this study indicated the importance of the pre-slaughter handling stages, evidencing those of greatest stress and threat to animal welfare and pork quality, which are transport time, resting period, lairage time before unloading, unloading time, and ambience.
