Left displacement of abomasum (LDA) is an important metabolic disease in dairy cows which cause a large economic loss in dairy industry. So determination of these changes will be important to predict the disease after parturition. In the present study, 14 serum biochemical parameters of cows with LDA before and after parturition were compared to those of healthy cows (control group) using several statistical models especially Logistic regression. In the statistical model changes in 6 parameters beta-hydroxy butyrate(BHB), Non esterified fatty acids(NEFA), Aspartate amino transferase(AST), Calcium, Sodium and Potassium between control and LDA groups was significant (P<0.05). Using the values of these 6 parameters in the Logistic regression formula one week after parturition, the odds of LDA would be calculated. So the owner would be able to predict the occurrence of LDA and protect the herd against it with correction of diet and treatment of LDA concurrent metabolic diseases.

Propofol is a short-acting intravenous general anesthetic for induction and maintenance of general anesthesia. Propofol used alone or in combination with other CNS depressant drugs in human and animals. Nowadays studies considering usage of anesthetic drugs in poultries for research and surgery purpose are in developing. Injectable drugs have problems in poultry, so inhalant anesthetic drugs are preferred. But sometimes inhalant anesthetic drugs have problems too. In this experimental study, we evaluate serum biochemical change subsequent propofol-induced general anesthesia in adult aborigine hen. Therefore 10 adult aborigine hens selected randomly. To induce anesthesia propofol (7.5mg/kg) injected intravenously and for maintenance propofol (0.5mg/kg/min) infused until 90 minute with infusion pump. During anesthesia the following biochemical factors were determined in 0, 15, 30, 60, 90 minutes and 24, 72 hours after anesthesia. Serum albumin, alanine amino transferase (ALT), aspartate amino transferase (AST), alkaline phosphates (ALP), bilirubin, blood urea nitrogen (BUN) and creatinine concentration were measured. Results showed that: bilirubin, BUN, ALP and creatinine concentrations significantly changed (p<0.05), but ALT, AST and albumin concentration had none significantly changed. Using this drug in poultry’s anesthesia and surgery needs to be investigated more.

In present study, we determined the effects of doxycycline on the serum biochemical parameters of Broilers. Forty Broilers (19 days old) were randomly divided into two groups of control and treatment. Bath groups were kept under the same environmental condition and nutrition. In the treatment group, 400 gr/ 1000 lit doxycycline was administered. After five days blood samples of all birds were collected. And their sera separated by centrifuging, then some of biochemical parameters were evaluated. Results showed that Alkaline phosphatase (ALP), Alanine aminotransferas (ALT), Aspartate aminotransferase (AST), billirubin and billiverdin concentration were significantly increased (p<0.05), but Calcium concentration was significantly decreased in treatment group. Evaluation of the serum levels of glucose and Phosphorous did not reveal statistically significant differences between treatment and control groups. In assessment of results, doxycycline administration can be used in broilers but it must be controlled in liver diseases because it can cause changes on liver parameters.
