Bighorn sheep (BHS) populations have been reported to experience high levels of morbidity and mortality following infection with . This contrasts with the subclinical presentation in domestic sheep (DS). Understanding this difference requires baseline knowledge of pre- and post-infection immune responses of both species.

The dairy industry relies on reproductive efficiency to maintain efficient milk production. Spontaneous abortion (SA), defined as pregnancy loss between gestation days 42 and 260, occurred in 4.5% of the artificially inseminated (AI) Holstein heifers and 31.

This study aimed to identify loci (p < 1 × 10) and gene sets (normalized enrichment score (NES) ≥ 3.0) associated with the number of times a heifer is bred to attain a successful pregnancy (TBRD) for Holstein heifers bred by artificial insemination (AI, n = 2754) or that were embryo transfer (ET, n = 1566) recipients. Eight loci were associated (p < 1 × 10) with TBRD in AI bred heifers and four loci were associated with TBRD in ET recipients.

Article Synopsis
  • * A study using genotypes from 81 flocks found that nearly all genetic variation (99.9%) comes from a single ancestral population, suggesting a current population size of around 150, but the breed should actually target a reference population of 15,000 for better genomic prediction accuracy.
  • * The average inbreeding level was about 16.6%, with specific genomic regions linked to production traits showing high levels of shared genetic material; addressing these could help improve selection outcomes,

The shift toward sustainable energy has fueled the development of advanced electrocatalysts to enable green fuel production and chemical synthesis. To date, no material outperforms Pt-group catalysts for key electrocatalytic reactions, necessitating advanced catalysts that minimize use of these rare and expensive constituents (i.e.
