Summary: In this study, a medium-free incubation method for hatching Pelodiscus sinensis eggs was developed and compared with the traditional vermiculite incubation method. The results showed that medium-free incubation did not significantly affect hatching success, body weight, carapace length, carapace width, plastron length, plastron width, and righting response time of P. sinensis compared to the traditional vermiculite incubation. Furthermore, light treatment shortened the incubation period and had negative effects on certain parameters during medium-free incubation. This study also discovered the phenomenon of egg-hatching synchrony in P. sinensis.

Summary: This review provides an overview of the current state of knowledge in poultry epigenetics, discussing issues relevant to overall poultry production and the improvement of health status. Environmental modulation has a significant influence on the regulation of epigenetic mechanisms in poultry, particularly during egg incubation before hatching. The epigenome of adult birds can be modulated by nutrition, supplementation, treatment, and modification of intestinal microbiota.

Summary: This study conducted a comprehensive assessment of slightly acidic electrolyzed water and benzalkonium bromide solution for egg disinfection. The results showed that slightly acidic electrolyzed water had high sterilization rates and no impact on eggshell quality and hatchability. It can be an alternative disinfectant to conventional chemical disinfectants.

Summary: This study aimed to develop algorithms for identifying unsuitable goose eggs for incubation in advance, including infertile eggs and those with unsuccessful embryo development. By measuring egg parameters, four novel indicators were established, which could effectively predict unsuitable eggs before incubation. The application of these indicators can help reduce hatching waste.

Summary: In alternative poultry production systems, the storage of hatching eggs is an important aspect that is less standardized than in intensive poultry farming. This study investigated the effect of long-term storage of game farmed quail eggs on hatchability, weight loss, chick weight, and incubation length. The results showed that hatchability decreased when storage was extended to 35 days, and the eggs progressively lost more weight as the storage time increased. The incubation period also increased with storage time, while hatching synchrony decreased.

Summary: In broiler breeder production, cracked or broken egg shells account for 2% of rejected hatching eggs, leading to reduced hatchability and lower chick quality. A study was conducted to examine the effect of sealing egg-shell cracks with surgical tape on hatching parameters. The results showed that sealing the cracks with tape improved egg weight loss during incubation and reduced embryonic mortality, resulting in hatching percentages comparable to the positive control group.

Summary: Within the blood-gorging insect Rhodnius prolixus, corticotropin-releasing factor/diuretic hormones (CRF/DHs) modulate feeding, diuresis, and reproduction. This study explores the role of Rhopr-CRF/DH in female reproduction and reveals its co-localization with the glycoprotein hormone GPB5. Knockdown of Rhopr-CRF/DH-R2, the receptor for Rhopr-CRF/DH, accelerates egg production and alters the expression of vitellogenin and its receptor, suggesting the involvement of the CRF-signaling pathway in reproduction.

Summary: This study found that temperature has a significant impact on hatching success, incubation length, and hatchling traits in green turtle eggs. Hatching success was lowest at 34 degrees C and growth rates were lowest at 26 degrees C. The optimal temperature range for embryonic development was found to be between 28 degrees C and 32 degrees C.

Summary: This study found that breeder age and eggshell thickness have an impact on the hatching results of broiler breeders. Eggs from middle-aged breeders had higher weight loss during storage and incubation, while eggs from old breeders had the lowest hatchability. Eggs with thick shells were more tolerant to the detrimental effects of storage.

Summary: Variation in life-history strategies is crucial for understanding population dynamics and adaptation, with nest microclimate driving important trade-offs and thermal gradients often explaining observed biogeographic and seasonal patterns. Our study implies an indirect effect of climate change on reproductive success and recruitment.

Summary: This study evaluated embryonic development, analyzed blood concentrations of glucose, T3, and T4 in embryos and goslings, and assessed the structure and temperature of the eggshell. The results showed that embryo development and hormone concentrations in the blood were influenced by the age and laying period of the geese. The thickness and density of the eggshell also varied with the laying age and period. Goose age, laying age, and laying period have significant effects on embryonic development and eggshell characteristics.

Summary: Incubation temperature significantly influences the development of Reeves' Turtles embryos and hatchlings, while substrate moisture mainly affects incubation duration and hatchlings' carapace width. The optimal incubation conditions determined in this study are a temperature of 29+/-0.5 degrees C and a substrate moisture level of 1:1.2, which lead to higher hatching success, shorter incubation duration, and better survival rates for this aquaculture species.

Summary: Hatching failure is common but understudied in birds. The safety of nests and larger clutch sizes, particularly among cavity nesters, are associated with higher rates of hatching failure. Nest temperature has little influence on hatching failure and most failures occur before or shortly after incubation. Predation risk may indirectly affect hatching failure.

Summary: In recent years, the nesting range of loggerhead sea turtles in the Mediterranean has expanded, reaching the Italian coastlines of the Tyrrhenian and Adriatic seas. Human activities like tourism, fishery, and marine traffic, as well as environmental changes, may influence the growth of microorganisms like Fusarium, which can cause hatching failures in sea turtles. The monitoring of northernmost loggerhead sea turtle nests in the Adriatic coastline of Italy in summer 2021 suggests that this area may be suitable for a part of the turtle's life cycle and emphasizes the importance of environmental changes, human activities, and emerging pathogens in sea turtle health research and conservation management.

Summary: Reproductive aging in animals involves substantial molecular and cellular changes, with interventions playing a key role in delaying this process. The model organism Caenorhabditis elegans has been instrumental in understanding the mechanisms driving reproductive aging and its impact on individual fertility as well as population dynamics. Various theories have been proposed to explain why reproductive aging occurs and how it has evolved, with C. elegans being a valuable tool for testing mechanistic and evolutionary models of reproductive aging.
