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

Journal 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.

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

Animal 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.

In silico genomic and proteomic analyses of three heat shock proteins (HSP70, HSP90-α, and HSP90-β) in even-toed ungulates

Electronic Journal of Biotechnology, 2021
Background: Heat shock proteins (HSPs) play important roles in the responses to different environmental stresses. In this study, the genomic and proteomic characteristics of three HSPs (HSP70, HSP90-α and HSP90-β) in five even-toed ungulates (sheep ...

Effects of Shade and Concentrate Supplementation on Heat Tolerance, Metabolic, and Hematological Responses of Holstein Cows in a Semi‐Arid Environment

New Zealand Journal of Agricultural Research, Volume 69, Issue 3, June 2026.
This study evaluated heat tolerance and biochemical and haematological responses of Holstein cows exposed to different environmental conditions (full sun or shade) and feeding regimens (with or without concentrate) in the semi‐arid region of Brazil. Sixteen adult cows were distributed across four treatments.

Factors influencing calf mortality in zebu and crossbred cattle reared under subtropical agroclimatic conditions

Indian Journal of Animal Sciences, 2019
Data on birth weight and mortality pattern of Zebu (Sahiwal and Tharparkar) and Crossbred (Holstein Friesian × Tharparkar) cattle spread over 16 years were utilized to analyze the causes of calf mortality and to study the effect of non-genetic factors ...

Integrative Genomics Identifies Candidate Genes Underlying Trypanotolerance in Hybrid African Cattle

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT Integrative genomics combines data from different omics sources to link genotypes and phenotypes with the aim of unravelling biological networks and pathways that undergird complex traits, particularly with respect to disease. In this respect, integrative genomics, leveraging population and functional genomic data, can be employed to ...

Prevalence of Trypanosome Infections in Cattle and Sheep in the Benin's West Atacora Agro-Ecological Zone [PDF]

Tropicultura, 2012
Trypanosomiasis remains one of the major constraints to ruminant livestock development in Benin. In order to determine the prevalence of trypanosome infections in the municipality of Ouake in the West Atacora agro-ecological zone, a parasitological study

Production objectives, trait and breed preferences of farmers keeping N’Dama, Fulani Zebu and crossbred cattle and implications for breeding programs

Animal, 2017
Many local livestock breeds in developing countries are being replaced by exotic breeds, leading to a loss of genetic resources. In southern Mali, for the past two decades, a trend towards increasing crossbreeding between the trypanotolerant N’Dama ...

Deciphering the Evolution Pattern of Structural Variations Overlapped With Repetitive Sequence During Cattle Evolution

Advanced Science, Volume 13, Issue 28, 18 May 2026.
The authors complement bovine pan‐SV with massive novel structural variations (SVs) identified through long‐read sequencing of 83 globally distributed cattle breeds. Repetitive sequence‐mediated SVs (rep‐SV) exhibit distinct dynamic patterns throughout cattle sub‐speciation and/or domestication processes, including uneven distribution between chr‐X and
