Background: The Taihe black-boned silky fowl, a distinguished indigenous breed of chicken, is renowned for its dual utility in both traditional medicinal and culinary applications. However, the breed faces significant challenges due to its suboptimal reproductive capabilities and a notably brief egg-laying period, which have impeded its broader development and cultivation. In this research endeavor, we employed an advanced, rapid DIA (Data independent acquisition) quantitative proteomics method on the Astral platform to meticulously analyze the ovarian proteome of these chickens.

The domestication of ducks represents a pivotal evolutionary shift from the unguided propagation of wild species to deliberate human-mediated selection, culminating in distinct behavioural, morphological, and physiological traits that differentiate domesticated ducks from their wild counterparts. This transition has yielded breeds with traits fine-tuned to specific economic roles, such as egg production, meat yield, or dual-purpose functionality. Duck domestication plays a significant role in poultry production globally, meeting the growing demand for eggs and meat in various regions.

The reproductive lifespan of female mammals is determined by the size of the primordial follicle pool, which comprises oocytes enclosed by a layer of flattened pre-granulosa cells. Oocyte differentiation needs acquiring organelles and cytoplasm from sister germ cells in cysts, but the mechanisms regulating this process remain unknown. Previously helicase for meiosis 1 (HFM1) is reported to be related to the development of premature ovarian insufficiency.

Article Synopsis
- - The study analyzed serum allergen-specific IgE (sIgE) in 3,822 patients with respiratory and skin diseases in Shanghai over one year to help understand and improve the diagnosis and treatment of allergies in the region.
- - Results revealed that 88.4% of patients tested positive for at least one allergen, with 72.9% exhibiting multiple allergy sensitivities; the most common allergens included house dust mites, milk, fungi, and certain tropical mites.
- - Statistical analysis indicated that certain allergens like cat dandruff were more prevalent in respiratory diseases, while food allergens like shrimp and crab showed lower positivity rates, providing insights into the allergen distribution for targeted prevention strategies.

Feather pecking (FP) is a significant welfare concern in poultry, which can result in reduced egg production, deterioration of feather condition, and an increase in mortality rate. This can harm the health of birds and the economic benefits of breeders. FP, as a complex trait, is regulated by multiple factors, and so far, no one has been able to elucidate its exact mechanism.
