“…It can promote oxidative stress, thereby increasing hydroperoxide and lipid peroxide production. These free radicals are detoxified by the glutathione peroxidase (GSH-Px), which can convert them into oxygen and water or non-toxic fatty acid hydroxides (Carroll and Forsberg, 2007).…”

“…Selenium is scarce globally, although it is essential to many organic functions, based on its antioxidant properties and its incorporation in selenoproteins such as glutathione peroxidases (GSH-Px) that protect cell membranes against free radical damage and eliminate peroxides from blood and extracellular space (15,16). The present study investigated the effect of Se-supplemented diets on anti-rabies humoral response of Nelore (Zebu) cattle under handling stress.…”

This study determined the correlation between serum cortisol levels and rabies antibody titers in cattle primo-vaccinated against rabies and supplemented with dietary selenium (Se). Sixty Nelore male calves (10 to 12 months old) received daily and individual dietary supplementation with 0, 3.6, 5.4 and 6.4 mg Se (groups Gc, G 3.6 , G 5.4 and G 6.4 , respectively). The animals were vaccinated against rabies (day 0) and subjected to handling stress in the corral for 120 days. Blood sampling procedures were performed on days 0, 15, 30, 60, 90 and 120. Cortisol levels increased until day 90, but had dropped significantly by day 120 (P < 0.01). Rabies antibody titers on days 30 and 90 were similar among Sesupplemented groups; in the control group, rabies antibodies decreased significantly from day 30 to 60, and 90 to 120. Serum cortisol levels and antibody titers were not correlated in most of the groups or blood sampling days. A positive correlation among these variables was found only in G 6.4 on days 60 (R = 0.513; P = 0.05) and 120 (R = 0.644; P = 0.009). In conclusion, repeated handling in the corral stresses cattle, but without compromising rabies humoral immune response.

“…The acute phase response (APR) is a nonspecific component of innate immunity, which may respond to infection, inflammation, tissue damage, or stress (Fisher et al, 2001;Hughes et al, 2014). Biological responses associated with the APR include fever, production of acute phase proteins by hepatocytes, and increases in circulating WBC (Carroll and Forsberg, 2007).…”

Castration has been shown to elicit physiological stress, inflammatory reactions, pain-associated behaviour, suppression of immune function, and a reduction in performance to varying degrees. The responses to castration using Burdizzo were investigated in four male West African Dwarf (WAD) goats hourly over a period of 3 hours. The bucks were castrated with Burdizzo clamp, blood samples were collected by jugular venipuncture for biochemical, hematological and hormonal analyses. The hematological values showed significant decreases (P<0.05) in PCV, Hb, Rbc, neutrophil throughout the period, while the White blood cell count decreased significantly 1 hour post castration. Respiratory rate increased significantly (P<0.05) throughout the post castration period of study, while the rectal temperature significantly increasing (P<0.05) for just an hour post castration. Cortisol level rose significantly (P<0.05) throughout the study period. Testosterone and estrogen levels fell after an hour though non-significantly (P>0.05) but later rose significantly (P<0.05) during the second and third hour post castration. The serum biochemistry changes observed include a significant rise (P<0.05) in AST, ALT, urea and Creatinine after 1 hour upon castration, but the values later significantly decreased (P<0.05) after the 2nd and 3rd hours. The serum electrolytes increased significantly (P<0.05) an hour post castration when compared with the pre castration values and later decreased significantly (P<0.05) at the 2nd and 3 hours post castration in comparison to the 1st hour value. There was a non-significant (P>0.05) increase in heart rate 1 hour post castration before returning to the pre castration value. This study concluded that the effects of three hours post burdizzo castration on hematological and biochemical profile fluctuated significantly in all the values under study and this calls for clinical surveillance among surgeons when such animals are brought for surgery during the acute period of castration. Also, this study will make information available for clinicians and researchers.
