Heat stress is a threat that can lead to significant financial losses in the production of poultry world’s tropical and arid regions. The degree heat (mild, moderate, severe) experienced by depends mainly on thermal radiation, humidity, animal’s thermoregulatory ability, metabolic rate, age, intensity, duration stress. Contemporary commercial broiler chickens have rapid metabolism, which makes them produce higher be prone negative effect birds’ physiology, health, production, welfare, behaviors are reviewed detail this work. appropriate mitigation strategies for equally explored review. Interestingly, each these finds its applicability at different stages poultry’s lifecycle. For instance, gene mapping prior breeding genetic selection during promising tools developing heat-resistant breeds. Thermal conditioning embryonic development or early life enhances ability birds tolerate their adult life. Nutritional management such as dietary manipulations, nighttime feeding, wet feeding often, applied with timely effective correction environmental conditions been proven ameliorate chicks birds.

Climate change and broiler production

Veterinary Medicine and Science, Journal Year: 2024, Volume and Issue: 10(3)

Published: March 20, 2024

Abstract Climate change has emerged as a significant occurrence that adversely affects broiler production, especially in tropical climates. Broiler chickens, bred for rapid growth and high meat rely heavily on optimal environmental conditions to achieve their genetic potential. However, climate disrupts these poses numerous challenges production. One of the primary impacts production is decreased ability birds attain potential faster growth. Broilers are possess specific traits enable them grow rapidly efficiently convert feed into meat. climates affected by change, consequent rise daily temperatures, increased humidity altered precipitation patterns create an unfavourable environment broilers. These impede development, preventing from reaching maximum influence, which crucial achieving desirable outcomes. Furthermore, exacerbates existing faced systems. Higher costs impact industry's economic viability limit availability quality nutrition birds, further hampering In addition scarcity, also predisposes chickens thermal stress. This review collates information its including nutrition, immune function, health disease susceptibility.
