Abstract
The subject of this dissertation is to study the different methods used for diagnosis of endometritis in the mare, to study the different methods used for treatment of endometritis in the mare and to assess the most appropriate treatment for endometritis in the mare. The present study was carried out from February 2012 to December 2013, on a number of 67 mares (Arabian mares from Al-Zahraa stud farm and working mares in Dakahlia and Gharbeya governorates). They were fed on alfa alfa and barley in the winter and on hay and barley in the summer. The clinical signs of the mares affected with endometritis in this study were repeat breeder, early pregnancy loss and in some mares dropping of secretions from the vulva . The trans-rectal ultrasonography was performed on the affected mares and the picture of most of the affected mares was presence of intra uterine fluid. This diagnosis was confirmed by applying of low volume uterine flush and cytologic examination. In this study, the microscopic picture of the cytology was the presence of multiple poly morphonuclear cells (PMNs) in one microscopic field which confirm that these mares were affected with acute endometritis. In some mares, their cytologic picture revealed the presence of lymphocytes which confirm that these mares were affected with chronic endometritis. In the present work, the animals were classified into four groups, the first group were 15 mares affected with endometritis that washed with saline intra-uterine. This group considered as control group. The second group was treated with Gentamicin 10% buffered with equal amount of sodium bicarbonate (NaHCO3 7.5%) intrauterine wash. The third group was treated by cefepime, a fourth generation cephalosporin intrauterine wash and the fourth group was treated systemically by ceftiofur, a third generation cephalosporin (I. M. injection). The results were analyzed statistically to assess the level of deference. For the first group, The number of cured mares that return to its normal fertility life in the second estrous cycle after treatment was 1 (Second estrous conception rate was 6.67%). The number of cured mares that return to its normal fertility life in the third estrous cycle after treatment was 5 (Third estrous conception rate was 33.33%). The total number of conceived animals was 6 (conception rate was 40%). The number of mares that retain their pregnancy was 4 (pregnancy rate was 26.66%). The treatment conception interval in the second estrous was (34.0±0.0) and in the third estrous was (87.4± 8.4). For the second group, the number of cured mares that return to its normal fertility life in the second estrous cycle after treatment was 4 (Second estrous conception rate was 25%). The number of cured mares that return to its normal fertility life in the third estrous cycle after treatment was 5 (Third estrous conception rate was 31.25%). The total number of conceived animals was 9 (conception rate was 56.25%). The number of mares that retain their pregnancy was 6 (pregnancy rate was 37.5%). The treatment conception interval in the second estrous was (34.75±2.4) and in the third estrous was (70.4±15.5). For the third group, The number of cured mares that return to its normal fertility life in the first estrous cycle after treatment was 2 (First estrous conception rate was 12.5%). The number of cured mares that return to its normal fertility life in the second estrous cycle after treatment was 2 (Second estrous conception rate was 12.5%). The number of cured mares that return to its normal fertility life in the third estrous cycle after treatment was 10 (Third estrous conception rate was 62.5%). The total number of conceived animals was 14 (conception rate was 87.5%). The number of mares that retain their pregnancy was 12 (pregnancy rate was 75%). The treatment conception interval in the first estrous was (12.0±6.9), in the second estrous was (30.0±1.0) and in the third estrous was (62.7±2.6). And for the fourth group, The number of cured mares that return to its normal fertility life in the first estrous cycle after treatment was 11 (First estrous conception rate was 55%). The number of cured mares that return to its normal fertility life in the second estrous cycle after treatment was 3 (Second estrous conception rate was 15%). The total number of conceived animals was 14 (conception rate was 70%). The number of mares that retain their pregnancy was 12 (pregnancy rate was 60%). The treatment conception interval in the first estrous was (20.0±0.4) and in the second estrous was (25.0±0.6).
