A single-step genome-wide association study combined with random regression models identified 17 candidate genes whose effects on milk urea nitrogen in Iranian Holstein cattle shift across early, mid and late lactation.
The most compelling candidates were genes flagged consistently across all five methods. Among them was MITF, described by the authors as a key regulator of pigmentation and protection against ultraviolet radiation. The second was ACSL6, which the authors note participates in…
A pilot pedigree-based breeding program in black soldier fly larvae achieved indicative genetic improvement in larval weight over seven generations, while rising inbreeding levels exposed the limits of small selection nuclei in industrial insect production. Black soldier fly larvae have…
A missense mutation in the sheep MC4R gene, enriched in year-round estrus breeds, boosted receptor signaling and steroidogenic gene expression in cell experiments. Breed classifications were drawn primarily from the reference work Animal Genetic Resources in China: Sheep and Goats, with…
An in silico analysis of resistant White Leghorn chickens co-infected with Eimeria maxima and Clostridium perfringens identifies hub genes, transcription factor motifs and microRNA interactions linked to necrotic enteritis resistance.
Researchers have mapped stretches of DNA linked to milk yield, milk composition and fatty acid traits in Holstein Friesian crossbred cattle in India, identifying 36 SNPs across multiple chromosomes, including one statistically significant marker and 35 suggestive ones. The genome-wide association study,…
A missense variant in the INHA gene was significantly associated with twin-bearing in 100 Kreishi ewes, with computational predictions suggesting possible effects on protein structure.
Long non-coding RNAs are emerging as a vast regulatory layer controlling growth, fertility, disease resistance and meat quality in livestock, with new CRISPR-Cas13 tools poised to convert transcriptomic catalogues into actionable breeding markers. Subject of Research: Long non-coding RNAs as…
Genome-wide scans of more than 16,000 cattle reveal distinct selection signatures and shared evolutionary backgrounds across Italy's five native beef breeds. Subject of Research: Haplotype-based selection signature analysis in five Italian beef cattle breeds Article Title: Detection of selection signatures reveals…
A microsatellite study of 409 sheep from eight Serbian Pramenka varieties found moderate to high genetic diversity and measurable population structure, with Lipska emerging as the most genetically distinct variety. Subject of Research: Genetic diversity and population structure among eight indigenous…
Breeding and editing livestock: genomic selection, gene-edited pigs that resist disease, heat-tolerant cattle and cloned animals.
