“…The WBC counts in our study were within the range reported in Wild Boar or feral pigs or even in domestic pigs, although a wider total WBC count range was found by these authors. This difference in the ranges could be due to either preexisting subclinical disease generally associated with leukocytosis and an increase in segmented neutrophils, or stress induced by transport or captivity prior to sampling which may have also caused stress‐related leukocytosis.…”

“…It has been shown that the stress response associated with chemical or physical restraint may influence hematology and serum chemistry variables . Thereby, acute stress associated with physical struggling or snare restraint and application of anesthetic agents induced marked changes in a series of hematologic and biochemical variables . In addition, it has been reported that stress can influence the immune response in domestic pigs .…”

Background Establishing reference intervals (RI) for hematologic and biochemical variables in wild animals presents great challenges because capture stress or anesthesia during sampling can affect blood variables. Objectives The aims of this study were to establish RI for hematologic and blood biochemistry variables for Wild Boar (Sus scrofa) caught using cage traps, and provide information on the studied variables for different age groups. Methods Blood samples were obtained from 89 Wild Boars captured by cage trap between 2005 and 2013 in northeastern Spain. Piglets were handled without anesthesia, while juvenile and adult animals were anesthetized using a combination of tiletamine and zolazepam. Blood samples were collected from the anterior vena cava and were placed into plain and EDTA tubes. Thirteen hematologic and 21 biochemical variables were determined. Reference intervals for piglets and juvenile and adult groups were determined, and differences between these groups were statistically analyzed. Results Adults had higher HGB, PCV, MCH, MCHC, neutrophil count, and total protein, albumin, creatinine, and chloride concentrations than juveniles; in contrast, juveniles had higher values for lymphocyte count, cholesterol concentration, and ALP activity. Conclusions Reference intervals determined in this study provide a baseline for interpreting hematologic and biochemical results in Wild Boar at different age stages, and contribute to optimization of the management of this species.

“…The decreased levels of urea suggest enhanced nitrogen retention in clenbuterol-treated animals, even though no difference was seen between the two groups at slaughter. Increased urea levels after the acute stress response are probably due to increased protein catabolism associated with muscle damage during transport (DUBREUIL et al, 1993), and are in part due to enhanced cortisol output (FOSTER and MACGARRY, 1988).…”

“…CPK significantly increased at slaughter and was higher in clenbuterol-treated than in control pigs, as also found by WARRISS et al (1990) in salbutamol-tremed pigs. CPK released into the blood is an indicator of muscle metabolism and increases as a result of stress (DUBREUIL et al, 1993) especially in stresssusceptible pigs (POLTARSKY et al, 1989). WARRISS et al (1990) suggested that there should be a higher propensity to produce pale, soft and exudative meat in BAA-treated animals.…”

Summary The aim of this study was to evaluate if metabolic and endocrine adaptive responses to stressful stimuli are influenced by clenbuterol treatment in pigs. Two groups of nine Goland barrows of 167 kg liveweight, fed diets containing 0 (control) or 1 ppm of clenbuterol (clenbuterol‐treated) for 40 days, were used. Blood samples were collected by jugular venipuncture the day before (day 40) and at slaughter (day 41). On day 40 clenbuterol‐treated pigs had lower levels of thyroxin, tri‐iodothyronine, insulin, urea and higher levels of lactate and creatine phosphokinase activity. On day 41, thyroxin concentration was lower and creatine phosphokinase activity higher in clenbuterol‐treated pigs than in controls. In response to transport and slaughterhouse procedures, most of the parameters considered both in clenbuterol‐treated and in control pigs increased.

“…Moreover, the similarity in the prevalence of gastric ulcers and the lack of any treatment effect on the haematological and biochemical profiles do not suggest that transient stray voltage was causing stress in the pigs (O'Brien, 1986;Dubreuil et aL, 1989).

The effects of transient stray voltage associated with an alternating current were evaluated in growing-finishing pigs from 9 to 22 weeks of age. Seventy-two pigs were assigned to 9 blocks of 8 animals each. In each block, the following treatments were randomly distributed: a constant voltage differential created between the feeder or drinker and the metallic floor (woven wire), at a level of 0 volt plus 2-volt pulses (0 V-2 V), 2 volts plus 3-volt pulses (2 V-5 V), 5 volts plus 3-volt pulses (5 V-8 V), and a control treatment without any voltage differential (0 V-0 V). The constant voltage was applied 24 h per day. The pulses of 3 s duration were in the form of an increase in the amplitude of the constant 60-Hz signal. One pulse appeared every 20, 40 and 100 s during the hour following feed distribution and every 60, 120 and 300 s during the rest of the day. The animals were fed ad libitum and received fresh feed twice per day. Once during the 2-week periods at 9-10, 13-14, 17-18 and 21-22 weeks of age, the behaviour of the pigs was recorded during the hour following the two daily feed distributions. Animal weights and blood samples were taken every 2 weeks, from 9 to 21 weeks of age. No significant effect of transient stray voltage on any of the variables measured for the feeding, drinking, sitting or lying activities was found (p > 0.05). At 9-10 weeks of age, the number of rooting bouts was higher for the 5 V-8 V treatment (p = 0.03) and the number of events of butting the penmate was higher for the 2 V-5 V treatment (p = 0.05). Although the water and feed intake did not differ between treatments (p > or = 0.39), the average daily gain of the control group was lower than that of treated groups (p = 0.04) at 9 and 10 weeks of age, while the pigs submitted to a 2 V-5 V treatment had a higher daily gain than the pigs in the other treatment groups (p = 0.05) at 17 and 18 weeks of age.(ABSTRACT TRUNCATED AT 400 WORDS)
