Adaptive immune response to a wild boar-derived recombinant hepatitis e virus capsid protein challenge in pigs.

Hepatitis E virus genotype 3 (HEV-3) is a zoonotic pathogen capable of infecting human, porcine, and other animal hosts. Despite a broad host range and abundance of species that act as reservoirs for human infections, no commercially available animal vaccines against HEV-3 are currently available. In the present study, we tested the capacity of recombinant aa 112-608 wild boar-derived HEV-3 capsid protein (rORF2p) to induce an immune response in immunized pigs.

The influence of lameness on several automatic milking system variables and reproductive performance indicators in dairy cows.

There is an increased interest in using automatic milking systems (AMS) to indirectly assess the welfare of dairy cows, but knowledge on analyzing the association between lameness, milk yield characteristics, and reproductive performance in cows is still insufficient. The main aims of this study were to evaluate the influence of lameness on several AMS variables and reproduc- tive performance indicators during the early stage of lactation and estrus in Lithuanian Black and White dairy cows, as well as to assess the associations between lameness, productivity and repro- ductive efficiency. A total of 418 milking cows (50.

Effect of Electromagnetic Field Exposure on Mouse Brain Morphological and Histopathological Profiling.

Introduction: Mobile phones (MP) and other electronic and communication devices that are used daily expose users to electromagnetic fields (EMF) and contribute to an increasing incidence of neurological disorders. Brain tissue is the closest organ to the MP as it operates, thus the influence of MP radiation on brain tissue is of particular concern, although research is still inconclusive. The present study investigated the possible effect of an EMF (1,350-1,375 megahertz (MHz)) from an MP on morphological and histopathological profiles in the mouse brain.

Evaluation of automatic milking system variables in dairy cows with different levels of lactation stage and reproduction status.

In this study, we hypothesized that differences of automatic milking systems (AMS) variables in dairy cows during estrus and through diverse stages of lactation can be suggested as alternative indicators to support the pregnancy in dairy farms using automatic milking systems. The key objectives were: (1) to determine the variation of automatic milking system indicators during lactation and to estimate the relationship with reproduction status in dairy cows; (2) to test the hypothesis that milking traits of cows can be influenced by estrus and conceiving, and can be used as a predictor of the likelihood of reproductive success in dairy herds. Estrus synchronization was performed in 368 healthy Lithuanian Black and White cows.
