  The present study was conducted in order to examine the effect of monensin on serum level of haptoglubolin in pregnant dairy cattle. About 20 heads of pregnant dairy cattle (5 months pregnant) were selected in two, control and treatment, groups. The cattle of two groups were in the same situation considering management, production and age. In treatment group about 200 mg monensin was added to the diet of each cattle head in addition to the ordinary diet of control group. On days of 0, 30, 90, 120, time of parturition and 2 weeks after parturition the blood samples was collected from jugular vein and then serum was separated. In all serum samples the haptoglobin serum level was measured by biochemical kit. The average of serum haptoglobin did not have meaningful difference between two groups on day of zero but in care group there was decrease in serum haptoglobin after the day of 30 and on the day of 30 the difference between two groups was not significant (p = 0.066). On the day of 90 and 120 this difference was significant and it was p = 0.037 and p = 0.04, respectively. On parturition time, haptoglobin serum level increased in two groups and this increase in treatment group was less than control group which was nonsignificant (p = 0.003) and 2 weeks after parturition it was low in treatment group which was not significant (p = 0.586). The changes of serum haptoglobin in control group was not meaningful on different times but in treatment group the serum changes was significant on days of zero and 30 (p = 0.04). The mean serum level of this protein in affected cattle to parturition diseases was greater than healthy carrel in two groups. Final result was that adding monensin to pregnant cattle diet led to decrease of haptoglobin serum level, 4 month before parturition.

  This study was conducted on 150 goats (up to 1 to >6 years) in Khoy area in the North of Iran at Spring of 2010 in order to seroprevalence of leptospiral infection. Blood samples were collected from the animals and sera were initially screened at dilution of 1:100 against 6 live serovars of Leptospira interrogans: Pomona, Canicola, Hardjo, Ballum, Icterohaemorrhagiae and Grippotyphosa using the Microscopic Agglutination Test (MAT). The serum positive goats were in 4-6 years and the seroprevalence of leptospiral infection was 13.3% in them. About 20% of infected goats were in the moist stables and 80% were in the moist (marshy) stables. There was a significant difference between the seroprevalence of disease in two kind of stables (p<0.05). Also statistically, a significant relationship observed between the increased age of examined animals and the seroprevalence of disease (p<0.05). The highest number of reactors in goats was 80% due to serovar grippotyphosa and 20% due to serovar Pomona. The majority of titer levels were 100 for all the serovars. These results confirm that the majority of leptospiral infections are asymptomatic and indicate the risk of exposure of organism to other animals.

  Theilleriosis is one of the common protozoan disease in cows that experimental figures of this disease has great help in diagnosis and treatment. This study aimed to evaluate serum concentrations of sialic acid (total sialic acid and lipid compound sialic acid and protein compound sialic acid) as markers of inflammation in infected cattle. In the large anilmal clinic of Islamic Azad University, Veterinary Faculty and some dairy cattle farm around Tabriz, 37 infected cows to Theilleriosis were determinded based on clinical and experimental signs. They obtained blood samples from the jugular vein and serum was isolated. Total 35 cows were taken as control samples. Serum levels of these parameters were measured using Sydow and Katpodis method. Mean values of serum sialic acid, lipid compound sialic acid and proteins compound sialic acid in infected cattle to Theilleriosis were 3.26±0.13, 1.10±0.070, 0.91±0.056 mmol L-1 and in healty cows were 1.96±0.12, 0.68±0.064, 0.74±0.061 mmol L-1, respectively that differences between the two groups in all three cases was significant (p = 0.000, p = 0.000, p = 0.046, respectively). It was found that patients with elevated serum levels of total serum sialic acid, total amount of lipid compound sialic acid and proteins compound sialic acid are increased. But there was no significant correlation between them (r = 0.136, 0.064, respectively). The final result is that increase of sialic acid serum concentration in infected cows to Theilleriosis is mark of inflammation trend and measuring this parameter in experimental verifying of Theilleriosis disease can be useful.
