Article Synopsis
- Lumpy skin disease (LSD) is a viral illness affecting cattle, leading to high morbidity and significant production losses, particularly in endemic areas like Ethiopia.
- Despite extensive vaccination efforts, outbreaks continue to occur, prompting a study to investigate the disease and isolate the virus for future vaccine development.
- The study collected biopsy samples from affected cattle, revealing a morbidity rate of 6.5%, a mortality rate of 0.5%, and confirmed LSDV presence through various molecular techniques, suggesting further genetic studies on the virus are necessary.
A cross-sectional calf mortality study was conducted in urban and periurban dairy farms in Addis Ababa, special zones of Oromia and Amhara regions in July and August 2015. The objectives of the study were to estimate the annual mortality and to assess the major causes of calf mortality in the dairy farms. One-year retrospective data on calf mortality were collected from 330 farms by face-to-face interview using the pretested and structured questionnaire format and direct observation of farm practices.

The study was conducted on 262 cross breed lactating cows selected from 12 intensively managed dairy farms. California mastitis test (CMT) and bacteriological culture methods were used as diagnostic tools.
