“…Similarly, Halliday et al (1977), Freeman et al (1984), Pijarska et al (2006), and Ondrasovicova et al (2008) found that transportation of a long duration reduced the glu-cose level in broilers. Suchy et al (2007) reported that the glucose level decreased in blood plasma of pheasants after a 4-h transport compared with a nontransported control group.…”

“…Other authors (Lin et al, 2000;Yalçin et al, 2004) reported that plasma glucose was higher during the summer than the fall after 1 h of transportation. Halliday et al (1977) reported that the level of uric acid in blood plasma increased after 1 to 2 h of transport in broilers. Similarly, Huff et al (2008) described how transport increased the levels of uric acid in turkeys transported for 3 h. According to Delezie et al (2007), transportation of broilers for a period of 1.5 h resulted in a significant increase in plasma uric acid concentration.…”

“…They found that the time in transit and the distance between the farm and the slaughterhouse increased the corticosterone level in plasma and reduced the glucose level in blood. Similarly, Pijarska et al (2006) detected a lower glucose concentration in birds after transportation lasting 18 h. Other research has described hypoglycemia in broiler plasma after transport for 2 to 4 h (Halliday et al, 1977;Freeman et al, 1984) and has suggested that this condition resulted from exhaustion of the hepatic glycogen stores. On the other hand, Warriss et al (1993) and Savenije et al (2002) found no significant differences in plasma glucose or lactate concentrations in broilers transported for 1.5 h.…”

The effect of transport distance on selected biochemical parameters (corticosterone, uric acid, triglycerides, total protein, glucose, and lactate) under various ambient temperatures was monitored in a group of unsexed Ross 308 broilers aged 42 d. Broilers were transported to the slaughterhouse over 3 different travel distances (10, 70, and 130 km). They were sampled before and after each transportation in 3 various periods with different ambient temperatures (-5 to +5°C, 10 to 20°C, and 25 to 35°C), which approximately correspond to temperature conditions during transport in individual seasons of the year (winter, fall, summer). The changes in biochemical parameters were specific in their dependence on the travel distance and the ambient temperature under which the broilers were transported. The highest corticosterone concentration was found in broilers before transport (i.e., immediately after catching, crating, and loading) at all ambient temperatures. The concentration of corticosterone was higher at winter temperatures than at summer and fall temperatures. Triglycerides decreased with travel distance, although this effect was detected under summer temperatures only. The concentration of total protein was higher only after 10 km of transport and then it decreased with travel distance at all monitored ambient temperatures. A highly significant decrease (P < 0.01) in the glucose level of broilers was observed after 130 km of transport when compared with broilers before transport at fall and winter temperatures. The effect of travel distance on lactate concentrations was the same at all monitored ambient temperatures, with the lactate level decreasing with travel distance. The results obtained indicate that pretransport handling procedures (catching, crating, and loading) may be more stressful for broilers than the transport itself. To improve broiler meat quality, it is necessary to meet the need for broilers to recover before being slaughtered. With regard to different seasons of the year, we can assume that transport under conditions of low ambient temperatures in winter represents a more stressful event than transport during fall and summer.

“…Overall, plasma glucose was affected by transport time, and glucose significantly decreased with the elapsed transport time. Several studies have suggested that poultry, when subjected to long-term transport, consistently develop hypoglycemia that may be the result of exhaustion of hepatic glycogen stores (Halliday et al, 1977;Freeman et al, 1984).

Transport stress in broilers: I. Blood metabolism, glycolytic potential, and meat quality

et al. 2009

The effect of transport stress on blood metabolism, glycolytic potential, and meat quality in broilers was investigated. Arbor Acres chicks (n = 360, 1 d old, males) were randomly allotted to 1 of 5 treatments: unstressed control, 45-min (short-term) transport with 45-min (short-term) recovery, 45-min transport with 3-h (long-term) recovery; 3 h (long-term) transport with 45-min recovery, and 3-h transport with 3-h recovery. Each treatment consisted of 6 replicates with 12 birds each. On d 46, all birds (except the control group) were transported according to a designed protocol. Transport time affected plasma glucose level (P<0.05) and glycogen level (P=0.06) in breast muscle as well as the area (P<0.01) and density (P<0.01) of IIa fibers. Glucose concentration increased slightly during the first 45 min of transport and then decreased dramatically in the long-term transported broilers (P<0.05). Long-term transport decreased the concentration of breast glycogen (P=0.06) and affected the size of IIa fibers in tibialis anterior by decreasing the area (P<0.01) with an increase in density (P<0.01). However, a long-term recovery after transport contributed to the homeostasis of blood corticosterone (CORT, P=0.05) and low levels of glycogen (P<0.05), lactate (P<0.01), and glycolytic potential (P<0.01) in thigh muscles. Interactions existed between transport and recovery time on area (P<0.05) and density (P<0.01) of IIa fibers. Furthermore, plasma nonesterified fatty acids increased significantly in the 3-h transport with 3-h recovery group (P<0.05) in comparison with the control. These results suggested that transport induced the release of plasma CORT and glycopenia, which affected the contractive status of muscle fibers by changing their area and density, and enhanced glycolysis and even lipolysis. A long-term recovery after transport was beneficial in lowering plasma CORT levels and reducing muscle glycolysis, which might improve broiler meat quality.

“…Handling in Rock Pigeons (Columba livia domestica) was associated with substantial increases in CK and decreases in UA (Scope et al, 2002). However, Halliday et al (1977) showed increased levels of UA in domestic chickens (Gallus domesticus). Baseline differences between populations might exist that explain all or part of the differences, but further research is needed to rule out handling-stress.…”

ABSTRACT:The eastern hellbender (Cryptobranchus alleganiensis alleganiensis) has experienced precipitous population declines throughout its range. Numerous factors are speculated to be involved, but no empirical evidence has been presented for any. We implemented a populationwide health assessment in Indiana, USA, examining both the physical well-being of individuals and the quality of their habitat. Physicochemical parameters were analyzed directly in the field and later in the laboratory, when appropriate. Samples were collected June 2008-October 2008 and June 2009-September 2009 for reproductive analysis, blood screening, and disease prevalence. Of 27 chemicals screened in water samples, three were found in the study site, including atrazine. Atrazine was found at levels reported to cause reproductive problems in other amphibians. Vitellogenin was detected only in females and proved a reliable indicator of sex. Sperm parameters were generally of high quality and similar to other populations. Most plasma parameters were similar between sexes, although there were significant differences in calcium and potassium concentrations. Abnormalities were common, occurring in 68% of individuals. No hemoparasites were found, but amphibian chytrid fungus (Batrachochytrium dendrobatidis) was detected on one individual. Our findings establish a baseline for hematology and water-quality parameters that can be used as a model for evaluating population health throughout the hellbender range.
