Zinc oxide nanoparticles influence methane production and endoparasitic infection in lambs with minimal changes in key bacterial taxa

Matej Leško, Alexandra Bombárová, Daniel Petrič, Dominika Batťányi et autres

ABSTRACT Zinc oxide nanoparticles (ZnO-NPs) represent a sustainable feed additive with potential anthelmintic effects and the ability to mitigate enteric methane (CH₄) emissions. This study evaluated the effects of ZnO-NPs as a commercial product (SkySpring Nanomaterials, Inc., Houston, USA) on dry matter …

Effect of zinc oxide nanoparticle supplementation on parasite infection and rumen environment of grazing lambs

Matej Leško, Alexandra Bombárová, Daniel Petrič, Michaela Komáromyová et autres

This study investigated the effect of zinc nanoparticles (ZnO-NPs) on the growth parameters, parasitological status, ruminal fermentation, and histopathology of lambs that were experimentally infected with Haemonchus contortus larvae. The infected lambs were divided into two groups ( n = 10/group) and …

Chicory modulates the rumen environment in lambs with endoparasites

Daniel Petrič, Matej Leško, Klára Demčáková, Michaela Komáromyová et autres

The most natural areas typically host a variety of plant species that serve as nutritional centers for grazing ruminants. We aimed to determine the growth parameters, histology, and ruminal microbial characteristics of lambs with endoparasites grazing on meadow pasture with experimentally sown …

Insights into the role of bioactive plants for lambs infected with Haemonchus contortus parasite

Michaela Komáromyová, Daniel Petrič, Klára Demčáková, Matej Leško et autres

Bioactive plants provide therapeutic and prophylactic effects to ruminants. We determined the effect of grazing on natural meadow grassland enriched with experimentally sown chicory (Cichorium intybus) on parasitological status, pasture larval infectivity, antioxidant parameters, and the histology of abomasal tissue in lambs …

Factors Affecting the Perception and Practice of Iranian Nomadic and Semi-Nomadic Pastoralists in Regard to Biosecurity Practices in Sheep and Goat Farms: A Cross-Sectional and Prospective Study

Zeinab Hatami, Richard Anthony Laven, Saeid Jafari-Gh., Matej Leško et autres

Preventing the spread of diseases between and within farms (biosecurity) is essential for minimizing animal mortality and morbidity, as well as for reducing the risk of spread of zoonotic diseases. These effects are even greater in countries such as Iran, which have …
