In the whole laying cycle, the late laying phase is the longest segment, and it directly determines total egg production and influences the timing of culling. To investigate the mechanisms underlying the decline in egg-laying performance du…

Alternative polyadenylation (APA) is a critical post-transcriptional regulatory mechanism, yet its role in follicular development and atresia in waterfowl remains poorly understood. To address this, we performed full-length transcriptome se…

In the field of genetic breeding, primordial germ cells (PGCs) have become essential cells for gene editing and genetic improvement due to their unique developmental potential and genetic characteristics. However, the low proliferation effi…

Despite several factors influencing reproduction in geese, but the precise molecular mechanisms of egg cessation are not fully understood. In the present study, the hematopoietic parameters and serum hormone levels in Wanxi white geese were…

Ovarian development is a complex process, with early stages laying a crucial foundation for subsequent egg production. To better understand this developmental trajectory from early stages to the peak of egg production, this study employed t…

The aim of this study was to investigate the effects of puerarin (Pue), a phytoestrogen, on the production performance, egg quality, endocrine hormones, antioxidant capacity, and intestinal morphology in aged laying hens. A total of 180 Hy-…

The proliferation and death of granulosa cells (GCs) in poultry play a decisive role in follicular fate and egg production. The follicular fluid (FF) contains a variety of nutrients and genetic substances to ensure the communication between…

High broodiness in Muscovy ducks impedes animal husbandry growth. The interaction between endocrine hormones and gut microbiota has been proven to play a crucial role in reproductive performance, and whether it can regulate the broody behav…

The underlying mechanism between the gut microbiota and reproductive function is not yet well-known. This study was conducted to investigate the effect of the administration of fecal microbiota transplantation (FMT) from highly laying rate …

Interleukin-1 receptor type 2 (IL1R2) is a decoy receptor for exogenous IL-1. However, its functional role in chicken immunity is poorly understood. Herein, chicken IL-1R2 (chIL-1R2) was identified and functionally characterized in vivo and…

The large tumor suppressor homolog 2 (LATS2), one of the central regulators of the Hippo/MST signaling pathway, plays an inhibitory role in ovarian function and different organ development and growth in mammals. However, the exact roles and…

Large ovarian follicles are primary characteristics of oviparous species. The development of such follicles is crucially governed by strict intrinsic complex regulation. Many aspects of the genetic basis of this regulation remain obscure. T…
