العلاقة بين درجة الحرارة و الرطوبة النسبية و معدل النبض و التنفس و درجة حرارة المستقيم في الأبقار المضربة

Abstract EN

This study was conducted at Animal Farm, College of Agriculture, University of Basrah and Animal Farm of Aked Agriculture Secondary School, Dhi-Gar Province during the period of 1/10/2013 to 1/7/2014.

So we can the effect of temperature,humidity and value (THI) monthly on pulsing rate,repiration rate and rectum temperature.It have been used 28 crossed cows of different ages and milking season.Cows were fed available feed within each season,while water was available during 24 hours.

Results shows foundation of significant effect (p<0.05) of average of temperature, humidity and value (THI) monthly on pulsing, respiration at morning and evening, so rectum temperature.

Maximum recrded parameters of June through the priod of study reached (1.32±82.11)beat/min, (2.11±55.69,0.72±19.38)Insp and (0.06±38.42)c° .

Through this month (June) it had been recorded the maximum average of temperature,so, the highest value(THI) through morning ,wile the general rate to both (36.51,43.86,29.16)c° and (72.43 at morning, 83.53 at evening, 78 for the general rate) unit.
