![]() This study provides strong evidence that kids born to SRLV-infected does grow equally well as kids from uninfected does, provided that the lactogenic viral transmission is prevented by maintaining strict separation between the offspring and mothers. The mixed linear model including four variables fitted as random effects (doe, kid, the year of kid’s birth and the exact age of a kid at weighing) and four potential confounders fitted as fixed effects (parity, kid’s sex, litter size and birth body weight) was developed and showed that BWT was not significantly associated with SRLV serological status of a doe, regardless of the time for which does had been infected before the delivery of the kid (p = 0.242). In total 620 goat kids were weighed at least once, excluding weighing at birth, providing 992 BWT records. Kids were weighed immediately after birth, and then 1–3 times within the first 3 months of life. Moreover, kids were weaned immediately after birth, fed on bovine colostrum and kept in strict separation from mothers to prevent SRLV lactogenic transmission. ![]() ![]() As a result all goats enrolled in the study were asymptomatic. Goats in the herd were regularly serologically tested and individuals showing clinical signs of caprine arthritis-encephalitis (CAE) were promptly culled. The study was carried out in years 2001–2017 in the research dairy goat herd. ![]() Keywords: Bangladesh, caprine arthritis and encephalitis, enzyme-linked immunosorbent assay, goat, risk factors, seroprevalence.A longitudinal observational study was carried out to evaluate the influence of prenatal exposure to small ruminant lentivirus(SRLV)-infected does on the body weight (BWT) of young kids. To eradicate the disease, screening and culling of infected goats from the herd might be implemented. The multivariable logistic regression model identified sex (Female odds ratio : 3.98 95% CI: 1.13–13.95), animal age (12–48 months OR: 4.93, 95% CI: 0.63–38.13), and biosecurity status (Poor biosecurity OR: 1.66, 95% CI: 0.46–5.92) as potential risk factors for CAEV seropositivity.Ĭonclusion: This study revealed the serological detection of CAEV in Bangladeshi goats where seroprevalence is found to be relatively low. The overall seroprevalence was 4.26% (95% confidence interval : 2.58–6.57). Results: Out of 446 serum samples, 19 samples were seropositive against CAEV. Logistic regression models were used to analyze risk factors and serological data to identify the potential risk factors. A commercial indirect enzyme-linked immunosorbent assay kit was used to screen blood serum for CAEV antibodies. ![]() Goat owners were interviewed using a pretested questionnaire to determine the risk factors. Materials and Methods: From July 2021 to June 2022, 446 goat serum samples were randomly collected from the study area. Therefore, this study aimed to estimate the seroprevalence of CAEV infection among the goat population in the selected goat-prone districts in Bangladesh and to identify the associated risk factors of the disease. However, no information in this country is available regarding CAE virus (CAEV) infection. Background and Aim: Caprine arthritis and encephalitis (CAE) is a multisystemic persistent viral disease of goat that causes significant economic losses to the farmers and livestock sector. ![]()
