Abstract :

Bovine Leukosis Virus (BLV) is a worldwide disseminated Retroviral infection. In this study, Enzootic form was investigated in Afyonkarahisar province. For this purpose, total of 6.631 adult cattle was sampled from both central and 17 borough. The collected 2.275 samples from small scale enterprices in Sinanpaşa, Sandıklı, Şuhut, Dinar, Çobanlar, Evciler, Hocalar, Sultandağı, Dazkırı, Bayat and Kızılören were found to be negative with ELISA. Positivity determined locations were İhsaniye (6/158, 3.79%), Bolvadin (5/367, 1.36%), Emirdağ (9/258, 3.48%), Başmakçı (2/242, 0.82%), İscehisar (2/177, 1.12%) and Çay (1/214, 0.46%). In addition, 3 big scale organised dairy herds were investigated. Out of 1.915 samples, 985 (51.43%) was determined as positive while 2 herds were negative, while in an only one, 60% positivity was detected. As according to test result, out of tested 6.631 samples, 1.025 (15.45%) was found to be BLV positive. It was concluded that, infection proportions were relatively low or absent in small scale family type farms but incidens could be quite high in intensive breeding due to ignored transmission ways like close contact for a long time, feeding of the calves with infected milk, injections and vaccination applies with same tools.
