Article Synopsis
- A citizen science survey in Poland involved 2169 beekeepers reporting losses of 9466 honey bee colonies from 2017 to 2022, accounting for 12.2% of winter losses.
- Small-scale apiaries experienced the highest loss rates at 14.8%, compared to 11.6% for large-scale and 11.4% for medium-scale apiaries, with the main issues being dead colonies linked to depopulation syndrome or starvation.
- Five management factors were identified, with practices like queen replacement being more frequent in large-scale apiaries, but the overall impact on loss rates varied and was complex depending on the apiary size.
Article Synopsis
- In 2023, a study assessed the genotypes of small ruminant lentiviruses (SRLV) in Hungarian goats, taking blood samples from 135 seropositive adults from 10 herds.
- The researchers used a two-stage nested real-time PCR to identify SRLV DNA, revealing that six herds had genotype A or B, while four herds had mixed infections.
- Findings indicated that 81.5% of goats tested positive for SRLV, with specific subtypes identified as A1/A18, A2, and B1, marking the first identification of both SRLV genotypes in Hungarian goats.
Astaxanthin due to its strong antioxidant activity is believed to reduce oxidative stress and therefore is considered as feed additive in pathological conditions and also for the athletes. It is promoted by several equine web portals, however, data supporting that concept in horses is limited. Thus, the aim of this study was to evaluate the effect of astaxanthin supplementation on the parameters of oxidative status in 3 years old, racing Arabian horses during long term observation and the changes related to a single training session of high intensity.

The disease prevalence has never been investigated in the Lithuanian goat population. Therefore, a descriptive cross-sectional study was carried out in 2021-2022 to determine if SRLV infection was present in the Lithuanian goat population and, in the case of a positive result, to estimate the true herd-level prevalence of SRLV infection and specify genotypes and subtypes of SRLV responsible for the infection.

- A serological and coproscopic survey was conducted on Polish goats to investigate the prevalence of the common liver fluke, focusing on 33 randomly selected herds between 2014 and 2022.
- Results showed that 33.3% of herds had at least one seropositive goat, but the overall rate of infected goats was only 1.2%, indicating low infection rates.
- The study concluded that liver fluke infection in goats is sporadic and less common compared to its prevalence in cattle and sheep, suggesting minimal treatment or prevention measures are necessary for goats.
