Abortion imposes great economical loss in productivity and by product of small ruminants. The present study was conducted to determine the rate of abortion and apparent prevalence of Brucellosis, Toxoplasmosis and Q-fever in aborted goats from June 2015 to August 2019 in North Shoa, Ethiopia. During consecutive years of clinical case study 503 does were entered to mating, of which100 (19.5 %) animals aborted. There were significant differences (p=0.013) in abortion among parities. A total of 35 serum samples were collected from aborted does within six months periods. All samples were screened initially with Rose Bengal plate test (RBPT) for Brucellosis. All RBPT positive were further tested by i-ELISA. Also, serums were tasted to screen specific antibody against Q-fever and Toxoplasmosis using i-ELISA. Of total tested 64.7 % and 8.6 % of them were positive for Q-fever and Toxoplasmosis, respectively, but neither of them was positive for Brucellosis. The present clinical study revealed that abortion was the cause of kids’ loss and serological investigation of antibody against Q-fever and Toxoplasmosis showed that the agents were the major causes of abortion. Even though there was no positive reactor does to brucellosis, the result must be interpreted with care since absence of evidence is not evidence of absence. Beside of this, some samples collected from active cases were sero-negative for neither of tested antibodies; it indicated there was other cause/s of abortion in the study site. These interesting findings deserve further detail study by using more sensitive diagnostic test in order to examine the full extent of the problem in small ruminant populations. Also, an awareness-raising campaign should be launched to educate farm workers and professionals about proper preventive and control measures for such zoonotic diseases

The present study was conducted from 2019 to 2020 in the Debre Birhan area of the Amhara region, Ethiopia, aiming to evaluate the effect of single-dose prostaglandin hormone in dairy cows and heifers at the smallholder farmer level. A total of 458 dairy cows and heifers were treated with 2ml of Synchromate® hormone, and after 77.82±2.74 hours, 286 of which (62.4%) were reported to have manifested estrus signs. Insemination was performed to 215 animals, 71 animals were not inseminated (the time for AI was passed when checked by rectal palpation) because of later reports by farmers after the cessation of estrus periods. Of the 215 animals that were inseminated, 82 (38.1%) conceived, and from the 82 animals that conceived, 79 (96.3%) gave birth. Estrus response and conception rate have not shown a significant difference between parity and body condition scores. However, treatment to estrus interval has been found to be significantly (p<0.05) influenced by parity, cows had shorter intervals than the heifers. This study indicated that there were problems in the detection and reporting of estrus response by the smallholder farmers, hence, requiring continuous training on dairy cow management.
