Estudio Serológico De Leucosis Enzoótica Bovina Y Su Relación A Parámetros Productivos

Enzootic bovine leukosis, a disease caused by the Bovine Leukosis Virus (BLV), It present a hight prevalence that is variable from one región to another among dairy cattle worldwide. In Ecuador, prevalences runging from 7% to 65% have been reported having important productive implications we compared the seropositivity of the animals by the specificity of the inmunoabsorbent assay linked to enzimes (ELISA) competitive – indirect for the diagnosis of LBE. In total, 40 female animals alder tan 4 years of were selected, distributed in 20 seropositive and 20 seronegative (LBE) belanging to the livestock association “SANAGUS” SA; Two blood samples were taken from the selected cows by punctureof the middle coccy geat, with the use of needle vacutainer red cup tuve for the serological diagnosis of VLBE and purple cup tubes for hematic biometry and an individual simple of 40 ml of milk fpr the physico- chemical analysis of its, of wich the analyzes were run in the laboratorios of Animal Health and milk quality control AGROCALIDAD (Tumbaco). The 40 animals were distributed into two groups; A control and an experimental We studied the variation of cut-off points of competitive - indirect ELISA betwen the disease and its correlation with hematic biometrics and productions parameters, the experimental group (T1) did not present a significant defference on the relation of the serological status to the VLBE in relation to the productiveparameters that were analyzed giving a value of (p>0.05). Also, there were no significant defferences regarding the diferent hematic parameters of the read series of T1 (p>0.05)
