dc.description.abstractLumpy skin disease (LSD) is an important viral disease caused by LSD virus belonging to family Poxviridae. The virus has much economic implication since it affects the fertility of bulls and cows alongwith decline in milk production and trade of animal products. The experiment aims to detect the changes in the spermiogram of breeding bulls affected by LSD and also to compare seminal parameters between different breeds. A total of 18 bulls of 3 different breeds were selected for study and they were divided into 3 groups on the basis of breeds with 6 bulls in each group i.e, 6 Cross bred Jersey (CBJ), 6 Jersey (JY) and 6 Cross bred Holstein Friesian (CBHF). In all the groups seminal parameters like post thaw motility, HOST, live sperm count, acrosomal integrity and Computer Assisted Semen Analysis (CASA) are studied before and after LSD virus infection. The mean post thaw motility, HOST, live sperm percent, acrosomal integrity values ranges from 52 to 60 (%), 53 to 58 (%), 86 to 88 (%), 78 to 81 (%) respectively before LSD and their corresponding value ranges from 40 to 47 (%), 36 to 45 (%), 67 to 68 (%), 58 to 64 (%) respectively after LSD. Similarly, CASA detected the mean progressive motility, VCL, VSL, VAP & wobble values ranges from 52 to 59 (%), 127 to 130 (µm/s), 92 to 94 (µm/s), 115 to 118 (µm/s) and 86 to 90 (%) respectively before LSD and their corresponding value ranges from 41 to 45 (%), 97 to 107 (µm/s), 74 to 82 (µm/s), 92 to 98 (µm/s) and 68 to 71 (%) respectively after LSD. It was found that all the seminal parameters including CASA values decreases significantly post LSD infection irrespective of breeds. When each parameter was compared individually between three breeds then there was no significant difference found for both before and after LSD virus infection which suggest that all the breeds produce semen of equal quality before infection and are equally affected after infection. Since, all the seminal parameters decreases post infection in all the bulls so the semen produced after LSD is of poor quality and should not be used for artificial insemination. Further research should be conducted on the fertility implication of LSD virus to produce semen of good quality and prevent the spread of disease.en_US
