Livestock Blastoids: In Vitro Blastocyst Models for Embryogenesis and Reproductive Technologies
Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.ABSTRACT Understanding early embryogenesis in livestock remains a persistent bottleneck in both reproductive biology and animal breeding. Work in domestic species has long been limited by restricted access to embryos, ethical considerations, and the complexity of peri‐implantation development, making mechanistic studies difficult.

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.ABSTRACT The aim of this study was to evaluate the effect of supplementing in vitro culture medium of porcine zygotes with interleukin‐4 (IL‐4) on their developmental competence and quality. Cumulus‐oocyte complexes (COCs) were matured and fertilized in vitro.

Recent Advances and Emerging Applications in Embryo Vitrification for Livestock
Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.ABSTRACT Vitrification has progressively supplanted conventional slow freezing as the method of choice for embryo cryopreservation in both human medicine and animal production, particularly for in vitro‐produced embryos and for species or developmental stages highly sensitive to conventional freezing.

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.ABSTRACT This study directly compares hCG and buserelin as ovulation‐inducing agents following eCG‐based superovulation in weaned donor sows, focusing on their practical impact on ovulation‐embryo synchrony under field conditions. Fifty‐five multiparous sows received 1000 IU eCG 24 h after weaning and were treated at onset of estrus with either 750 IU ...

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.ABSTRACT The efficiency of AI in sheep depends partly on maintaining sperm function during storage. This study compared INRA 96 and a skim milk‐based formulation for storing ram semen at 15°C for 6 h, evaluating sperm quality and IVF and field fertility outcomes. INRA 96 showed higher VCL, ALH, and sperm viability after 6 h of storage.

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.ABSTRACT Sirtuin 1 (SIRT1) is a NAD+‐dependent deacetylase involved in chromatin remodelling. In this study, we evaluated whether sperm SIRT1 inhibition affects early embryonic chromatin dynamics. Sperm were treated with sirtinol during capacitation or during both capacitation and fertilization. SIRT1 inhibition increased acH4K16 in the male pronucleus

Embryonic stem cells: modelling effects ofearly embryo environment
, 2013 The Developmental Origins of Health and Disease (DOHaD) hypothesis proposes that embryonic environment can induce permanent changes in metabolism during development, increasing the risk of disease in adults. Adverse environments during critical stages of
