“…They stand out among cattle in the Americas due to their distinctive coat and skin coloration; their coats are typically white, often speckled with black spots, and their skin is highly pigmented, as exemplified by their black ears. This coat-skin pattern also occurs in British White and Chillingham/White Park cattle [68], and the White Fulani cattle of West Africa [69]. For White Park cattle, it has been demonstrated that their coat colour variation is caused by a duplication in the KIT gene and an aberrantly inserted KIT gene on BTA29 [70].…”

Criollo cattle, descendants of animals brought by Iberian colonists to the Americas, have been subject to centuries of natural and human-mediated selection in novel tropical agroecological zones. Consequently, these breeds have evolved distinct characteristics such as resistance to disease and exceptional heat tolerance. In addition to European taurine (Bos taurus) ancestry, it has been proposed that gene flow from African taurine and Asian zebu (Bos indicus) cattle has shaped the ancestry of Criollo cattle. In this study, we analysed Criollo breeds from Colombia and Venezuela using whole genome sequencing data to examine population structure and admixture at very high resolution. We did not detect evidence of African taurine admixture in Criollo cattle; however, there was evidence of longstanding zebu ancestry in one breed (Hartón del Valle). In addition, we detected selection signatures associated with a myriad of adaptive traits, revealing genes linked to thermotolerance, reproduction, fertility, immunity, and distinct coat and skin coloration traits. This study underscores the remarkable adaptability of Criollo cattle and highlights the genetic richness and potential of these breeds in the face of climate change, habitat flux, and disease challenges. Further research is warranted to leverage these findings for more effective and sustainable cattle breeding programmes.

“…The concentrations of uric acid in the blood, lactate dehydrogenase and MDA decreased. Moreover, the findings of Akosile et al (2022), who evaluated the effect of in ovo feeding of cinnamon extract at different levels, indicated that the hatchability of broiler chicks from eggs injected with 4 mg cinnamon extract during incubation was enhanced. Similarly, Khan et al (2022) found that liver function, antioxidant status, growth performance and meat quality were favourably impacted by dietary cinnamon in broiler chickens.…”

“…The environmental temperature outside this range imposes stress on the birds. Avians are more vulnerable to a harsh temperature than other animals as they do not possess sweat glands and are covered with thick feathers, which prevent easy heat loss from their bodies to the environment (Loyau et al, 2013; Uyanga et al, 2022), causing them to be susceptible to thermal stress, which is one of the greatest environmental problems facing chicken farmers, particularly in the tropics (Ajayi et al, 2022; Kpomasse et al, 2021; Oke et al, 2022; Oke, Uyanga, et al, 2021). Studies have demonstrated that poultry under heat stress exhibits poorer growth performance, productivity indices, metabolism, immunity, behaviour, well‐being and physiological responses (Meteyake et al, 2020; Oladokun et al, 2023; Uyanga et al, 2023).…”

The increase in global temperature and consumers' welfare has increased the use of phytogenic feed additives (PFA) to mitigate the negative effects of heat stress on chickens in recent years. Various bioactive compounds capable of improving the thermotolerance of broiler chickens during exposure to thermal challenges have been identified in different plant species and parts. This review is an overview of the roles of bioactive compounds of different PFA, such as polyphenols and flavonoids, antioxidants, growth‐promoting and immune‐modulating agents, in heat stress management in broiler chickens. Common PFA in use, particularly in tropical environments, are also discussed. An understanding of the roles of the PFA in chickens' thermotolerance could further stimulate interest in their use, thereby improving the birds' productivity and addressing consumers' concerns. This review collates the existing data on the roles of herbs in mitigating heat stress on chickens and highlights future research perspectives.

“…These changes disrupt the delicate balance of the ecosystems, affecting the growth, development and productivity of crops and livestock. The tropics are particularly susceptible to the effects of climate change due to their high temperatures and diverse ecosystems (Oke et al., 2022 ; Thomson et al., 2015 ). This review critically examines the challenges and opportunities bedevilling broiler chicken production as it embraces the ongoing onslaught of climate change and its antecedent of global warming, especially in the tropical regions of the world.…”

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