  To evaluate stress and metabolic adjustments in buffaloes with Post Parturient Haemoglobinuria (PPH), certain serum enzymes viz. Gamma-Glutamayl Transferase (GGT), Glucose-6-Phosphatase (Glc-6-Pase), aldolase, glucose-6-phosphate dehydrogenase, glutamate dehydrogenase, malate dehydrogenase, arginase and 5'nucleotidase enzymes were determined. Simultaneously haemoglobin and serum calcium, phosphorus, glucose and proteins were also determined. Blood samples were collected from adult female healthy and buffaloes with post parturient haemoglobinuria. In affected group the mean values of all the parameters were compared with respective healthy mean values. Significantly (p≤0.05) increased serum GGT activity in buffaloes with PPH indicated stress. Activities of the enzymes related to glycolysis and hexose monophosphate shunt were found to be decreased in affected animals. Activities of other enzymes like Glc-6-Pase, GDH, MDH, ARG and 5'NT were found increased significantly (p≤0.05) in the affected cases. This pattern was suggestive of metabolic adjustments where rate of glycolytic pathway decreased and rate of gluconeogenesis was observed to be increased in the affected cases. Correspondingly, serum glucose concentration of affected animals was significantly (p≤0.05) higher. Serum calcium showed non significant (p>0.05) difference whereas serum phosphorus, proteins and haemoglobin levels decreased significantly (p≤0.05) in affected cases. Decreased levels of phosphorus and disturbed calcium to phosphorus ratio suggested that phosphorous deficiency plays a key role in causing haemoglobinuria in buffaloes. Pattern of variation in the activities of the enzymes related to various metabolic processes revealed the metabolic adjustments. The data obtained in the present investigation support the concept that sustained PPH stress may represent an integrating mechanism underlying metabolic adjustments for homeostasis. Better understanding between PPH stress and metabolic homeostasis can be instrumental in the design of novel therapeutic strategies.

  Present investigation was launched to detect oxidative stress in pregnant and non-pregnant Murrah buffaloes during extreme ambiences. Serum oxidase and peroxidase profiling was used as a tool to detect oxidative stress. Blood samples of apparently healthy adult female Murrah buffaloes were collected to harvest sera during extreme hot cold and moderate ambiences. Moderate mean value of serum oxidase was 50.32±1.21 UL-1 and of serum peroxidase was 49.51±1.11 mUL-1. Extreme hot and cold ambiences resulted into a significant (p≤0.05) rise in the activities of serum oxidase and peroxidase. Animals were classified as non pregnant milch, pregnant milch and pregnant dry and activities of both the enzymes were compared. It was observed that mean values of both the enzymes in non-pregnant milch, pregnant milch and pregnant dry differed significantly (p≤0.05) from each other, respectively in all the ambiences. Non pregnant milch animals showed lowest activities whereas pregnant dry animals exhibited highest activities of both the enzymes. Multipara animals showed significantly (p≤0.05) higher activities than primipara. Serum oxidase and peroxidase are considered as important markers to assess oxidative stress. Increased activities of both the enzymes reflected the presence of oxidative stress in the buffaloes. It was concluded that extreme ambiences resulted into oxidative stress affecting the animals of all the physiological states. In each ambience the magnitude of increase was greater in pregnant dry animals. Trend was similar in all the ambiences but impact was maximum during hot ambience. Multipara animals showed greater changes than primipara. It can be stated that multipara and pregnant dry animals require proper care and supplementation of immuno-nutrients in order to protect them from the ensuing risk of oxidative stress. Further serum oxidase and peroxidase activities can be used effectively in detection of oxidative stress.

  An investigation was carried out to assess oxidative stress in goats of Marwari breed affected from gastrointestinal parasitism and pneumonia belonging to farmers’ stock of arid tract of Rajasthan State, India. The animals were grouped into healthy and affected. All the blood samples were collected in sterile tubes with anticoagulants for erythrocyte separation and determination of erythrocytic Catalase (CAT) and Superoxide Dismutase (SOD) as biomarkers of oxidative stress. Activities of both the enzymes were significantly (p≤0.05) higher in affected animals in comparison to healthy lot. Erythrocytic catalase activity was 2.37 times higher in goats having gastrointestinal parasitism and 3.06 times higher in goats affected with pneumonia. Erythrocytic superoxide dismutase activity was 4.77 times higher in goats having gastrointestinal parasitism and 6.40 times higher in goats affected with pneumonia. It was observed that goats affected with pneumonia showed higher magnitude of enzyme activities in comparison to those having gastrointestinal parasites. Magnitude of change was greater in SOD activities than CAT activities. It can be concluded that gastrointestinal parasites and pneumonia served to produce oxidative stress in the goat. Catalase and superoxide dismutase are considered as potent biomarkers of oxidative stress. They are also named as antioxidant enzymes. Increased activities of both these enzymes signified the presence of oxidative stress in order to combat excessive production of free radicals. Antioxidant supplementation is recommended in cases affected with conditions like parasites and pneumonia to protect the animals from oxidative stress and ensuing damage to cellular machinery.
