Abstract
A cross-sectional study was conducted on reproductive organs of cows slaughtered in Addis Ababa and Adama municipality abattoir with objective of characterize the pathological lesions and isolate and identify possible aerobic bacteria from lesion. Out of the 209 genital tracts examined 12.9% (n=27) were pregnant and excluded from study. From total 182 reproductive organs examined 55 (30.2%) have one or more visible gross lesions. The most common abnormalities encountered were follicular cysts (2.20%), Luteal cysts (1.6 %,) Par ovarian cysts (3.3%), ovarian hypoplasia (2.2%), ovarian bursa adhesion (2.7 %), ovarian hemorige (1.6%), endometritis (18.7%), Pyometra (2.2%), Mucometra (1.1%) and Hydrometra (1.6%) with endometritis being the most frequent abnormality. Age, breeds, body conditions (BCS) and origin of animals were not statistically associated with the disorders (P>0.05). Endometritis were the major disorder recorded in this studies accounting for 34 (18.7 %) and all 34 endometritic ureine tissue were positive either single and/or mixed bacteria. E. coli 17 (50%), S.aureus 18(52.9%), S. hicus 1(2.9%) S. intermedius 2(5.9%), C.N.S. 12(35.3%), Streptococcus spp. 24 (70.6%) Proteus bulgaris spp 5(14.7%), and C. fundi 1(2.9%) were the bacteria isolated. It could be concluded that reproductive tract abnormalities were important diseases in the study areas which could have considerable impact on the reproductive performance of cows and in fact could be the sole reason for coming of these cows to abattoir. Another thing that worth mentioning was that significant (12.9%) of number of pregnant dairy cows were slaughtered which in fact should not have been happened.
