Special Issue Information

Dear Colleagues,

The Animals journal is hosting a Special Issue on “Heat Stress Management in Poultry” addressing the critical challenges posed by rising temperatures in poultry farming. Heat stress negatively affects poultry's physiological functions, immune responses, and productivity, leading to economic losses and welfare concerns. This Special Issue will explore scientific advancements in mitigation strategies, including nutritional, environmental, and genetic approaches. Given the increasing frequency of heatwaves due to climate change, research in this field is vital for ensuring sustainable poultry production. By understanding and implementing effective management practices, we can enhance poultry resilience, improve productivity, and promote animal welfare in heat-stressed environments.

This Special Issue aims to improve the productivity of poultry through various methods, such as feed and environmental management in high-temperature stress conditions. We invite you to submit papers on the many recent studies on the management of various high-temperature stress specifications, whether original research articles, reviews, systematic reviews, case reports, or communication, are welcome.

We look forward to receiving your contributions.

Mitigating stress responses is crucial for maintaining optimal productivity and profitability in modern poultry production. The effects of early feed withdrawal (EFW) and vitamin C (Vit C) supplementation, both individually and in combination, on heat-stressed broilers’ productivity, stress responses, and metabolic markers were investigated. In total, 240 newly hatched Cobb-500 male chicks were randomly distributed to four treatment groups (six replicates × 10 birds per group). A basal diet was offered to the control group; meanwhile, the EFW group underwent a 24 h early feed withdrawal on day four of age. The Vit C group was given 200 mg/kg vitamin C daily, and the EFW + Vit C group received both interventions. The study was executed under hot summer conditions, where the average minimum and maximum temperature-humidity Index (THI) were 29.15 ± 0.78 and 33.34 ± 0.76, respectively. The results demonstrated a superior stress-mitigating effect when EFW was combined with Vit C supplementation, leading to a significant improvement in productive parameters and elevated blood metabolic hormone levels. Additionally, total antioxidant capacity was enhanced, hepatic endogenous antioxidant enzyme expression was upregulated, and stress biomarkers were reduced. Furthermore, the economic efficiency indicators were significantly improved with EFW, and when EFW was combined with Vit C addition. These findings suggest that integrating multiple stress mitigation strategies, such as EFW and Vit C supplementation, may be more effective in relieving the adverse effects of heat stress by restoring homeostasis and optimizing broilers’ productivity and profitability.

Effects of Cool Water Supply on Laying Performance, Egg Quality, Rectal Temperature and Stress Hormones in Heat-Stressed Laying Hens in Open-Type Laying Houses

Abstract
We used an animal welfare-certified open-type layer farm and analyzed the egg production, egg quality, rectal temperature, and yolk corticosterone levels of laying hens supplied with cool water during the summer season (avg. 33 ± 3.89 °C). A total of 5750 Hy-Line Brown [...] Read more.
We used an animal welfare-certified open-type layer farm and analyzed the egg production, egg quality, rectal temperature, and yolk corticosterone levels of laying hens supplied with cool water during the summer season (avg. 33 ± 3.89 °C). A total of 5750 Hy-Line Brown laying hens at 53 weeks of age were used, and two treatment groups were established: a control group (2900 hens) and a cool water treatment group (2850 hens). The water temperature of the control group was 25.3 ± 0.8 °C and the cool water was 20.1 ± 0.3 °C; all other environment parameters (lighting, ventilation, temperature, feed, etc.) were the same. The experiment was conducted for a total of 9 weeks (between July and September 2024), and during this period, the temperature–humidity index (THI) inside the breeding facility averaged 85.21, which corresponds to the cool water supply range (80 < THI < 90). As a result, the cool water treatment group maintained high productivity and showed low mortality (p < 0.05). In addition, hens provided with cool water showed high eggshell strength and low yolk corticosterone levels (p < 0.05). The core finding of this study is that the supply of cool water in summer is effective in maintaining the productivity and egg quality of laying hens and reducing HS. This is significant in that it suggests it is possible to manage laying hens in summer in a simple way, and it can also be used as basic data for designing future studies, such as using a combination of natural products including vitamins and minerals.
