Genetic Parameters of Methane Emission, Feed Efficiency, Feeding Behaviour, and Growth Traits in Beef Cattle

open access: yesJournal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 496-507, July 2026.
ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus, especially Nellore cattle, remain limited.

Contribution of Fat Adjustment to Residual Feed Intake Estimation in Beef Cattle

open access: yesJournal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 602-612, July 2026.
ABSTRACT Including fat thickness as a covariate in the regression model used to calculate residual feed intake (RFI) could help preserve carcass quality traits, such as marbling, flavour and juiciness, by accounting for variation in fat deposition.

Engineering a Virus‐Derived X Family DNA Polymerase FvPolX for de novo DNA Synthesis

open access: yesAdvanced Science, Volume 13, Issue 32, 9 June 2026.
In this study, a Faustovirus‐derived polymerase (FvPolX) is engineered based on structural and sequence analysis of PolX enzymes. The optimal mutants demonstrate substantially enhanced catalytic activity toward dNTPs and 3′‐ONH2‐dNTPs compared to the wild‐type enzyme.

The Path to Future‐Proof Photovoltaics in Europe: Current Status and Impact of Technological Innovation on Reliable and Bankable Photovoltaics

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 6, June 2026.
This article provides an overview of the current state of the art and future improvements in PV technology and explains how changes in the technology and design of individual PV components—at the module level, the balance‐of‐system (BOS) level, or the PV plant level—can affect the reliability, durability, and energy output of a PV system.

Influence of MC1R Gene Variants on Coat Color of Indicine Cattle Breeds

open access: yesAnimal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT Indicine cattle display a broad range of coat colors, representing a relevant and breed‐defining trait required for registration in breeder association. Among the genes involved in pigmentation, MC1R stands out for modulating the synthesis of melanin‐related proteins and remains poorly explored in indicine cattle breeds. Therefore, we aimed to

Genetic Diversity of the Beta‐Casein Gene in Brown Swiss and Creole Cattle From the Peruvian Highlands

open access: yesAnimal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT Cattle's milk and derivatives are essential for human nutrition. However, up to 90% of people experience gastrointestinal discomfort after consumption. Milk digestibility depends on its protein composition. Casein, about 80% of milk proteins, includes beta‐casein (CSN2) with two variants: A1 and A2. The A1 variant is linked to gastrointestinal

Stage‐Dependent Transcriptional Reprogramming of B‐Cell Receptor Signaling and Antigen Presentation During Bovine Leukemia Virus–Driven Lymphomagenesis

open access: yesAnimal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT Bovine leukemia virus (BLV), an oncogenic deltaretrovirus, establishes lifelong infection in cattle and induces enzootic bovine leukosis in a subset of animals following prolonged latency. Despite extensive evidence of immune dysregulation, stage‐specific transcriptional reprogramming of B cells, the primary viral reservoir remains ...

ASIP Variants in Livestock: It's Not Black and White

open access: yesAnimal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT Fur and feather pigmentation play an important role in the survival and reproduction of many species, as well as in selective breeding and agriculture. The synthesis of pigment molecules, eumelanin and pheomelanin, is partially regulated by the agouti signalling protein (ASIP) encoded by the ASIP gene.
