The Turkmen horse is one of the oldest breeds in the world with unique characteristics in agility, endurance and jump, being publicly acclaimed. Laminitis affects the limbs and decreases athletic performance. Radiographic evaluation is essential to confirm the sinking diagnosis in every breed of a horse suffering from laminitis. Since no information about distal phalanx radiographic measurements in this breed has been reported, the current study was designed and conducted. In the present study, 24 clinically sound registered Turkmen horses of both sexes (15 mares and nine stallions) were selected. Lateromedial radiographic views of both front distal phalanges were taken, focusing on the distal phalanx. After magnification correction, images were used to measure founder distances (FD) and other distal phalanx radiographic measurements using an image processing program. There was no significant difference between radiographic measurements of the left and right front feet. The FD had a significant positive correlation with weight. The horses under 3 years of age had a significantly greater U angle than the horses over the age of three. Also, palmarocortical length (PCL) in the Turkmen stallions was significantly higher than mares. In this investigation, PCL in horses under the age of three was significantly lower than horses over 3 years of age. The values determined in this study can be used as baseline data of front feet in Turkmen horses.

Chlamydia abortus (C. abortus) is a Gram-negative intracellular bacteria responsible for major economic losses due mainly to infection and subsequent induction of abortion in several animal species and poses considerable public health problems in humans. This study was conducted to determine the prevalence of antibody against C. abortus in sheep and goat population of Khorasan Razavi province located in northeastern Iran. Four hundred fifty-two (271 sheep and 181 goats) sera samples from 40 sheep/goat epidemiologic units located in 11 counties were selected. Sera were assayed for antibodies against C. abortus using ELISA assay. Out of 452 sheep and goat sera, 44 [9.70% (95.00%CI: 7.10%-12.40%)] were positive for C. abortus antibodies. 28 out of 40 epidemiologic units (70.00%) and 10 out of 11 counties (91.00%), at least one seropositive sample was found. There was no significant difference between the seropositivity of sheep and goats. Age, sex, and location did not show significant relationship with the test results. The results showed that C. abortus was circulating in wide parts of Khorasan Razavi province. Considering the economic and public health importance of C. abortus, measures should be taken to help prevent its spread and to reduce the zoonotic risk of C. abortus in the studied region.

Abstract
Black zira (Bunium persicum) is a medicinal plant and spice, naturally grows in Iran. The aim of this study was to investigate the combined effects of different concentrations of Bunium persicum essential oil (EO; including 0, 0.08, 0.16 and 0.24%), three incubation temperatures (15, 25 and 35˚C), three ...

Black zira (Bunium persicum) is a medicinal plant and spice, naturally grows in Iran. The aim of this study was to investigate the combined effects of different concentrations of Bunium persicum essential oil (EO; including 0, 0.08, 0.16 and 0.24%), three incubation temperatures (15, 25 and 35˚C), three levels of pH (5, 6 and 7 adjusted by hydrochloric acid), and three inoculum size (102, 103 and 104 CFU mL-1) on the growth of Staphylococcus aureus in the brain heart infusion broth. Black zira EO was extracted and its component was identified using gas chromatography-mass spectrometry (GC-MS) analyses. The experiment was carried out in triplicate. Growth was monitored by visible turbidity during a 30-day period. To evaluate effects of explanatory variable on time to detection (TTD) of bacterial growth, parametric survival models based on Log-normal distribution was used. All explanatory variables had significant association with time to detection (p < 0.05). The final model accurately predicted the growth initiation and inhibition of S. aureus.

To describe proportion and pattern of culling in commercial dairy herds of Khorasan Razavi Province, this survey was carried out from 21st March 2008 to 20th March 2009 in 15 industrialized dairy herds. For each culled cow data related to parity at culling, last calving to culling interval and primary reason for culling were recorded. Annual herd exit rate was 20.9%. Out of a total of 652 culled cows, the proportions of culled dairy cows were due mainly to involuntary culling with very small proportion of voluntary culling (4%). The involuntary culling were mainly from infertility or reproductive disorders (23.6%), udder disorders (17.5%) and digestive tract disorders (15.9%). Average ± SD of parity at culling was 3.15 ± 1.96. Culled cows from digestive tract disorders, injuries and infectious diseases were significantly younger than those of other culling reasons (P < 0.05). Mean ± SD of last calving to culling interval was 194 ± 159 days. Culled cows from digestive tract disorders, injuries and udder disorders were removed earlier in lactation period than cows culled from reproductive disorders, infectious diseases and lameness (P < 0.05). Low proportion of voluntary and high percentage of involuntary culling specially from health problems should be considered as an important economic loss and precaution measures are necessary to reduce this loss.
