The Physiological Effect of Different Types of Water used to Thermally Stressed Ewes During the Summer Season

Abstract

Abstract This study was conducted in the sheep field of the Department of Animal Production-Faculty of Agriculture - University of Kirkuk for the period from 15/6/2021 to 15/9/2021, The study targeted the role of water types in influencing some of the chemical and biological qualities of ewes exposed to heat stress in the summer. 20 sexually mature ewes were used at the age of 1.5 year with an average weight of 44.12 kg, The animals were divided into four groups, each group included five ewes of homogeneous weights, and then randomly divided the coefficients into groups, The first treatment was irrigated with tap water, the second treatment was irrigated with well water, the third treatment was irrigated with tap water treated magnetically (1500 gauss) and the fourth treatment was irrigated with well water treated magnetically (1500 gauss). The results of the study showed a significant decrease (p≤0.05) in the level of glucose and the level of AST and ALT enzymes for magnetically treated water groups. The results did not show significant differences between the treatments in the level of total protein, as there were differences mathematically, where the two groups outperformed the treatment with magnetically treated water, as well as showed a significant increase (p≤0.05) in the level of creatine and cortisol in the second treatment and decreased in the magnetically treated water totals.
