Hepatitis E virus (HEV) is the causative agent of acute hepatitis E infection in humans. Two epidemiological patterns of the disease exist-endemic and sporadic. Genotypes 1 (HEV-1) and 2 (HEV-2) are transmitted through contaminated water and are responsible for the outbreaks of many large-scale epidemics in developing countries of Asia and Africa.

The objective of this study was to determine the relationship between the MRF gene family members and slaughter characteristics in Saanen kids with varying slaughter weights. Twenty male kids of the Turkish Saanen breed were individually fattened for 60 days after weaning under an intensive management system. The kids were divided into two groups: low slaughter weight (L; = 11; ≤29 kg) and high slaughter weight (H; = 13; >29) at the end of the fattening.

Antibiotic resistance genes (ARGs) are emerging as significant environmental contaminants, posing potential health risks worldwide. Intensive livestock farming, particularly swine production, is a primary contributor to the escalation of ARG pollution. In this study, we employed metagenomic sequencing and quantitative polymerase chain reaction to analyze the composition of microorganisms and ARGs across four vectors in a typical swine fattening facility: dung, soil, airborne particulate matter (PM), and fodder.

Myostatin (MSTN), a member of the TGFβ superfamily, negatively affects skeletal muscle growth and controls muscle development at stages of pre-natal muscle growth. Marker-assisted selection with molecular markers of the MSTN gene can be used in animal husbandry for higher-quality and more economically profitable lambs. The study aims to identify multi-locus genotypes within the MSTN gene regions as molecular markers for fattening, feed efficiency, and carcass traits in Latvian sheep.

Article Synopsis
- Tibetan sheep are traditionally grazed on pastures without extra feed, but now they are increasingly being fattened in feedlots, prompting a study comparing growth and health outcomes between two methods: pasture grazing (PG) and stall feeding (SF).
- The study found that SF sheep had better average daily gains, higher white blood cell counts, and lower platelet counts compared to PG sheep, while PG sheep showed higher serum antioxidant activity and protein levels.
- Additionally, the rumen analysis revealed distinct bacterial communities between the groups, with PG sheep showing greater diversity and a dominant presence of certain bacteria, highlighting the nutritional differences affected by feeding methods.
