Weighted Single‐Step GWAS Reveals Genetic Mechanisms Underlying Pregnancy Loss in Early Nellore Heifers

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT Pregnancy loss (PL) affects reproductive efficiency in beef cattle, yet its genetic architecture remains poorly understood in Bos indicus populations. Here, PL was defined as failure from pregnancy diagnosis to calving, capturing a window approximately 60 days after the breeding season.

COMPARISON OF hCG AND GnRH FOR SYNCHRONIZATION OF THE FOLLICULAR WAVE IN SAANEN GOATS DURING THE BREEDING SEASON

Slovenian Veterinary Research
This study aimed to compare the effects of a single dose of GnRH or hCG administered at the beginning of the short-term oestrus synchronization protocol on ≥4 mm diameter follicles in Saanen goats during the breeding season.

Integrating cryobanks into conservation frameworks: The case of boreal caribou in Ontario

Conservation Science and Practice, Volume 8, Issue 10, October 2026.
Conservation cryobanks are a powerful but underutilized complement to conventional recovery strategies such as habitat protection and population monitoring. Here, we present a transferable, stepwise framework for integrating cryobanking into formal species recovery plans, including guidance on population prioritization, partner engagement, and the ...

Assessing the Value of Coordinated Sire Genetics in a Synchronized AI Program [PDF]

Synchronized artificial insemination was used to inseminate cows using different types of sire genetics, including low-accuracy, calving-ease, and high-accuracy. These three calf sire groups were compared to calves born to cows bred using natural service.

A Spatial Clustering Approach of Economic Activities: An Application to the Agribusiness Sector in Brazil's Midwest Region

Geographical Analysis, Volume 58, Issue 4, October 2026.
ABSTRACT The spatial distribution of economic activities is central to regional economics. However, empirical tools for comparing industries based on the similarity of their spatial distributions remain limited. Traditional cluster analysis typically ignores geographical distance and connectivity, while spatial methods focus on clustering places rather

Early Labor Market Outcomes of Young Adults From Same‐Sex Families: Evidence From Population Data

Journal of Marriage and Family, Volume 88, Issue 5, Page 1266-1283, October 2026.
ABSTRACT Objective This study offers the first population‐based evidence on how young adults from same‐sex families fare when entering the labor market shortly after leaving full‐time education. Background Same‐sex couples' parenting rights remain controversial in many countries.

Comparison of Tree‐Based Machine Learning Algorithms for Classification of Livestock Breeds Based On Post‐Thaw Spermatological Parameters

Veterinary Medicine and Science
Reproductive efficiency is a crucial determinant of livestock productivity, with sperm quality being a key factor in successful fertilization. The quantitative assessment of spermatozoa using computer‐assisted sperm analysis (CASA) yields valuable ...

Seminal Extracellular Vesicles as Molecular Modulators of Male Reproductive Function

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Extracellular vesicles (sEVs) contained in seminal plasma (SP) maintain, in concert with free SP‐components (proteins, hormones, cytokines, metabolites and antioxidants) under an endocrine umbrella the functional in vivo homeostasis of ejaculated spermatozoa. The sEVs define a generic mixture of nanovesicles delivered by male epithelial cells,

Differentially expressed miRNA Cargo From Boar Seminal Extracellular Vesicles Is Linked With Motility Quality in AI Doses

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Sperm motility is a key parameter for male selection and is closely linked to male fertility status. miRNAs have been proposed as fertility biomarkers, and their regulatory effects on sperm motility have been previously investigated. In the present study, the miRNA cargo from three different sources, seminal extracellular vesicles, free ...

Small and Large Seminal Extracellular Vesicles Differentially Modulate Capacitation‐Related Parameters in Frozen–Thawed Porcine Epididymal Spermatozoa

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Seminal extracellular vesicles (sEVs) have been proposed as modulators of sperm function, but their exact role remains unclear. Most studies use ejaculated sperm for clarification. This approach has limitations; nevertheless, as ejaculated sperm have already been exposed to their own native sEVs, which hinders the assessment of their specific ...
