Summary: In this study, the levels of serum corticosterone, cortisol, and glucose were measured to evaluate the responses of fish to seven common stressors. The results showed that corticosterone and cortisol exhibited different patterns of dynamic changes, and glucose levels were influenced by both hormones. Corticosterone seemed to respond to stress earlier than cortisol and together they regulated glucose levels to cope with stress.

Summary: 17 beta-hydroxysteroid dehydrogenase type 2 (17β-HSD2) plays an important role in the regulation of estradiol (E2) availability in adipose tissues by converting E2 into estrone (E1). This study found significant conversion of E2 into E1 in omental (OM) and subcutaneous (SC) adipose tissues of women, with higher expression and activity of 17β-HSD2 in OM compared to SC adipose tissue. Additionally, the activity of this enzyme was negatively associated with body mass index, waist circumference, lean body mass, and SC adipose tissue areas.

Summary: Broiler chickens are prone to various health and welfare issues, with behaviour showing strong associations with health indicators. Better growth and feed efficiency were observed in conventional broilers, while specific behaviours were identified as indicators of good or poor health outcomes. These behavioural measures not only reflect health status but also provide insights into motivational and affective aspects of welfare, suggesting the importance of incorporating behaviour into broiler welfare assessments.

Summary: This study investigated the effects of different dietary amino acid levels on body weight, egg production and composition, fertility, hatchability, and embryo mortality of Cobb 500 SF broiler breeders up to 65 weeks of age. Results showed that moderate-AA and standard-AA diets resulted in the best hen-housed egg production at 65 weeks. The study concluded that amino acid levels during rearing have a significant impact on broiler breeder reproductive performance.

Summary: This study compared a novel crossbred slow-growing broiler breed with a conventional fast-growing broiler to assess their suitability as an alternative for chicken meat production in Australia. The crossbred reached the target weight later than the fast-growing broiler, but displayed longer latency-to-lie, higher thigh, drumstick, and wing yields, as well as darker and redder meat. The fast-growing broiler outperformed in feed conversion efficiency, antibody production, apparent metabolizable energy, breast yield, and meat drip loss, suggesting that the crossbred is a suitable candidate for a slow-growing alternative in Australia.

Summary: The study investigated the effects of eggshell temperature and CO2 concentration on incubating eggs, finding that the impact of CO2 concentration (at concentrations <= 0.8%) on embryonic development and chicken quality appears to be limited when eggshell temperature is maintained at a constant level. Moreover, a higher eggshell temperature from day 8 of incubation onward seems to negatively affect chicken quality at hatch.

Summary: The current study investigated the potential use of avian beta-defensin-1 peptide as a candidate agent against coccidiosis infection in broiler chickens. In-silico analysis was employed to study the structure of the peptide and its mode of action. The results showed that treatment with beta-defensin-1 peptide led to a significant reduction in oocyst count and down-regulation of beta-defensin 1 and 4 expression. These findings may contribute to the development of novel approaches for coccidiosis control in broilers.

Summary: This study evaluated the impact of different dietary factors on the metabolic regulation of chicken liver. It found that supplementation of butyrate in the diet decreased levels of insulin receptor and glucagon receptor, but increased levels of mTOR protein. The use of wheat-based and lowered protein diets increased gene expressions of GCGR and mTOR in the liver. These findings contribute to a better understanding of glycemic control in birds and offer opportunities for improving production parameters and broiler welfare.

Summary: Beta-lactam antibiotics are widely used in human and veterinary medicine, but their excessive use has led to the spread of deadly antibiotic-resistant bacteria. This study found that beta-lactam antibiotics were commonly prescribed in integrated broiler operations, and their use was associated with an increase in beta-lactam-resistant E. coli isolates. These findings highlight the importance of strengthening farm management practices and reducing antibiotic use.

Summary: Incubation and hatching commonly take place at hatcheries. Recent developments have introduced innovative housing systems that transport fertilised eggs from the hatchery to the grow-out facility, where they hatch. We investigated the effects of prolonged transport on the development of slow growing broiler chicken strain and found that transport leads to an autonomic stress response in chicken embryos, but had no further effects on other indicators of prenatal stress.

Summary: The acclimatization of certain ectothermic vertebrates to winter conditions involves reduced energy consumption, achieved through decreased movement activity, depression of cellular functions, or switching to anaerobic energy production. This study on crucian carp showed that winter-acclimatized fish exhibited lower metabolic rates and a shift to anaerobic energy production during anoxia. Winter dormancy in crucian carp is achieved through active reduction of energy consumption, a slowed metabolic rate, and a direct response to oxygen absence.

Summary: According to life-history theory, there might be different immunological strategies between reproductive and non-reproductive periods due to limited resources. Our study on two sympatric marine fish species, rockfish and sandperch, found that reproductive individuals showed lower immune function, but higher levels of natural antibodies in rockfish females, compared to their non-reproductive counterparts. On the other hand, reproductively active sandperch males showed lower levels of natural antibodies and higher neutrophil to lymphocyte ratio and spleen index compared to non-reproductive males. The study highlights the species-specific patterns of immunity and the potential influence of resource limitation and abiotic factors on immune trade-offs in fish.

Summary: This study cloned the genes encoding glucokinase and glucose-6-phosphatase catalytic subunit in largemouth bass, revealing their distribution and transcriptional regulation. The results showed that the functions of G6pc and Gck in LMB were highly conserved in evolution, and the interconversion of glucose and G6P in the liver was well regulated at the transcript level under high starch diet, but a futile cycle was induced after a glucose load.
