Determination the Normal Parameters (amplitude and duration) of Electrocardiogram Waves in River Buffaloes (Bubalus Bubalis) of Khuzestan

چکیده مقاله:
An easy way to evaluate the cardiovascular system is recording the cardiac electrical activities. Reviewing the available literatures suggests that buffalos ECG compared to other large animals have been neglected and the carried out studies in this field are too limited. Using this method for the diagnosis of cardiac disorders needs the standardization, not only among animal species but also among different breeds of a species. The present study was performed to determine the normal parameters of electrocardiogram in 100 clinically healthy buffaloes of different ages and sexes. The buffaloes were divided into male and female and two age groups (less than 2.5, and more than 2.5 yrs.) on the base of dental formula. After taking the anamnesis and performing a clinical examination, electrocardiogram was obtained based on base - apex lead system with the paper speed of 25mm sec-1 and sensitivity of 10 mm mV-1 at rest. Results showed that regardless of age and sex, the median and interquartile range of P, R, S and T waves' amplitude (voltage) was, 0.18±0.04, 0.69±0.40, 0. 97± 0.31 and 0.20 ±0.25 mV, respectively and the duration of p wave, QRS complex, and T wave was determined 0.06 ±0.01, 0.06 ±0.01 and 0.08 ± 0.02 seconds, respectively. Only in a less than 2.5 years old female buffalo, Q wave was recorded, the amplitude of this wave was 0.07 mV. Statistical method showed that among different ECG parameters, there was significant difference between the two sexes (p< 0.05), only in amplitude of S wave. Also there were significant differencesbetween two age groups in all of the electrocardiogram parameters with the exception of P and R amplitude (p

The aim of the present was to evaluate the prevalence of H9N2-specific antibodies among water buffaloes (Bubalus bubalis). To this end, blood samples were obtained from 80 randomly selected water buffaloes, 40 cases of which were obtained in the winter months, and 40 cases were sampled in the spring months. The presence of H9N2-specific antibody was determined by hemaggl...

Epidemiology of ectoparasites of buffaloes was studied in Kurigram district of Bangladesh from November, 2007 to October, 2008. A total of 236 buffaloes were examined, among them 61.86% were found infested with one or more species of ectoparasites. Three species of ectoparasites were identified of which, two species were arachnids, namely, Boophilus microplus (13.98%), Haemaphysalis bispinosa (...

Background: A number of studies have demonstrated membrane lipid peroxidation (LPO) as one of the causes of defective sperm function in liquid semen preserved at 4◦C and cryopreserved semen. Some attempt has been made to preserve sperm parameters, particularly sperm motility, by adding some elements and Materials to the semen before freezing. Materials and Methods: To investigate effects of cop...

The world buffalo population is about 168 million, and it is still growing, in India, China, Brazil, and Italy. In these countries, buffalo genetic breeding programs have been performed for many decades. The occurrence of congenital malformations has caused a slowing of the genetic progress and economic loss for the breeders, due to the death of animals, or damage to their reproductive ability ...
