Abstract
Post-parturient period consider one of the most important stages in production phases of dairy animals. During this period animals subjected to sever metabolic modification and load, which affect negatively on general health of dam and predispose them to several metabolic disorders.
This study conducted using of 58 dairy animals (22 buffaloes, 12 native cows and 24 cross breed), aged 2- 5 years. These animals were investigated in this study during the period from December 2017 to April 2018.These animals selected from farms in El- MiniaGovernorate.
Animals were examined clinically at first and third weeks after parturition. Two blood samples (whole blood sample and blood serum sample) were collected at the first and the second at the third week of lactation from each animal. Blood serum samples were subjected for investigation of total proteins, albumin, total bilirubin, liver enzymes (AST, ALT, GGT), BHBA, triglyceride, total cholesterol and HDL. Whole blood sample were collected on anticoagulant (sodium fluoride) containing tubes for obtaining blood plasma for estimation of NEFA andglucose.
Results of biochemical examination in buffaloes revealed that there were a significant increment in the level of total proteins, globulin, NEFA and triglyceride and non-significant change in albumin, A/Gratio, glucose,
BHBA, Total cholesterol, HDL, LDL, AST, ALT, GGT and Total bilirubin in the first week after calving when compared to its level in the third week after calving.
The result of native bred cows revealed that there were a significant increment in the level of total proteins, globulin, NEFA and Total bilirubin; decrement in the level of A/G, HDL and triglyceride and non-significant change in albumin, glucose, BHBA, Total cholesterol, LDL, AST, ALT and GGT levels in the first week after parturition when compared to its level in the third week ofparturition.
Investigation of this parameters in cross bred cows revealed that there were non-significant change detected in the level of total protein, globulin, albumin, A/G ratio, NEFA, BHBA, glucose, total cholesterol, triglyceride, HDL, LDL, AST and ALT and decrease in GGT and total bilirubin levels in first week after parturition when compared to its level in the third week of parturition.
There were slightly variations between parameters in diseased groups of all breeds when compared to healthy corresponding ones in the first week after calving.
