GIMENEZ, G; ALONSO, N; VERA, G  e  PEDROZO, R. SEROPREVALENCE OF NEOSPOROSIS AND ITS EFFECT ON THE INTERVAL BETWEEN BIRTHS IN DAIRY COWS OF THE CENTRAL DEPARTMENT, PARAGUAY - YEAR 2018. Compend. cienc. vet [online]. 2019, vol.9, n.1, pp.30-34. ISSN 2226-1761.  https://doi.org/10.18004/compend.cienc.vet.2019.09.01.30-34.

The objective of this research was to evaluate the seroprevalence of Neosporosis in dairy cows and its effect on the interval between births, the same was carried out in the districts of San Lorenzo, Ñemby and Nueva Italia of the Central Department during the year 2018. There were selected 87 animals to wich blood samples were taken from the medial coccygeal vein, which were deposited in test tubes without anticoagulant for subsequent centrifugation, the serum obtained from each sample in microcentrifuge tubes, were sent refrigerated to the SENACSA ​​Laboratory, where they were studied using the indirect ELISA method for diagnosis, finding the following results: 41.4% (36 samples) were positive. In the evaluation of the interval between births it was found that there is a statistically significant difference (p = 0.01) between the seropositive animals with an average (± SD) of 546 days (± 153) and the seronegative with an average (± SD) of 463 days (± 119). In all the sampled establishments, a total of 13 abortions were registered, of which 10 animals were seropositive to Neospora caninum.
