“…The chicken embryo responds to the environmental temperature around day 15 of incubation when the hypothalamus–pituitary–thyroid (HPT) and hypothalamus–adrenocortical axes (HPA) control the thermoregulatory mechanism and manage stress responses, respectively [ 42 ]. An increased incubation temperature during the development of the HPT and HPA axes could have long-lasting effects on the body function and behavior in chicks post-hatch [ 17 ].…”

The phenomenon of increasing heat stress (HS) among animals is of particular significance when it is seen in economically significant industries, such as poultry. Due to the identification of the physiological, molecular, and genetic roots of HS responses in chickens, a substantial number of studies have focused on reducing the effects of HS in poultry through environmental management, dietary manipulation, and genetic alterations. Temperature manipulation (TM) during embryogenesis has been claimed to increase the thermal tolerance and well-being of chickens without affecting their capacity for future growth. There has been little investigation into the vulnerability of the epigenome involving TM during embryogenesis, although the cellular pathways activated by HS have been explored in chickens. Epigenetic changes caused by prenatal TM enhance postnatal temperature adaption and produce physiological memory. This work offers a thorough analysis that explains the cumulative impact of HS response genes, such as genes related to heat shock proteins, antioxidants, and immunological genes, which may aid in the enhanced adaptability of chickens that have undergone thermal manipulation during their embryonic stages.

Background and Aim: Over the last decades, the poultry industry has experienced steady growth. Although the industry is gradually expanding in Indonesia, poultry feed production has always been expensive. There is a need to study alternative ingredients to obtain affordable feed from natural resources. Chaetomorpha linum (CL) is an abundant macroalgae available throughout the year in Indonesia. This study aimed to determine the effect of CL on the histological structure of the small intestine, pectoralis muscle, growth performance, and meat quality of broilers. Materials and Methods: This study used 300-day-old chick (DOC) male broilers that were reared until they were 21 days old. This study used a completely randomized design with four treatment groups and five replications, and each replication group contained 15 DOC individuals. The treatment groups consisted of Control (CON), CON basal feed (BF), CL1 (0.75%/kg BF), CL2 (1.5%/kg BF), and CL3 (3%/kg BF) groups. The histological structure of the small intestine, pectoralis muscle, growth performance, and meat quality of the broiler was examined. Results: Small intestine and pectoral muscle histomorphology, growth performance, and meat quality were significantly improved in the CL2 (1.5%) and CL3 (3%) groups compared with the CL1 (0.75%) and CON groups. Conclusion: Dietary CL supplementation ameliorates small intestine and pectoral muscle histomorphology, growth performance, and meat quality of broilers. Keywords: Chaetomorpha linum, growth performance, pectoral muscle, small intestine, water-holding capacity.

“…At hatching, TM broiler chicks were heavier compared to control chicks, whereas yolk‐ free body masses were identical. They attributed these findings to the faster growth of internal organs and breast muscles than body weight gain between ED14‐18, resulting in significant increases in percentages of these organs and heavier weights at hatch for TM chicks than control chicks (Yalcin et al, 2022).…”

“…At hatching, TM broiler chicks were heavier compared to control chicks, whereas yolk-free body masses were identical. They attributed these findings to the faster growth of internal organs and breast muscles than body weight gain between ED14-18, resulting in significant increases in percentages of these organs and heavier weights at hatch for TM chicks than control chicks(Yalcin et al, 2022).Regarding the time window of TM (early/late),Alkan et al (2013) explained that TM (+3.3°C) during late embryogenesis stage (ED12-14) decreased hatching weights in both sexes of Japanese quail embryo while early-stage TM (ED6-8) increased boilers final body weight at 35 days of age. It is worth noting that the regular growth and development of Japanese quail embryos are relatively slow during ED10-16(Bai et al, 2016).Concerning the duration of manipulation (length of exposure), an intermittent exposure for a short duration of the time combined with a relatively high temperature, for example, +1.5 or 2°C, 2-6 h/d, and longer duration combined with moderate elevation in temperature can bring out benefits to post-hatch growth.…”

The major efforts to improve feed conversion, increase the body weight and breast muscle yield of broilers have been focused on feeding and management at the post hatch period. However, incubation temperature is the most significant factor for the egg hatching rate, chick quality, and post hatch performance. Therefore, incubation factors affecting the performance should be taken with necessary precautions. Incubation temperature not only affects the early development of the hatchlings but also has a lasting impact on the characteristics of the chicks, such as final body weight and meat quality traits. This article provides an overview about embryonic thermal manipulation (TM) of domestic fowls and review the lucrative and deleterious effects of embryonic TM on embryo development, muscle growth, thermotolerance acquisition, and immunity.
