“… Schalkwyk et al (2000) noticed that hatchability amounted to 1·83% for an increase of 1° ( R 2 = 0·96) when ostrich eggs were rotated hourly through angles ranging from 60° to 90°. In a recent study, Guo et al (2021) recorded a shortened incubation duration and improvement in hatchability and goslings’ quality when eggs were turned at a wider angle (60° compared with 50°). They also observed an increase in late embryos and goslings’ weight correlate with a significant upregulation of genes in the somatotropic axis (GHRH, GH, and IGF-1 mRNA expression) and muscular development (pax7, MyoD, MYF5, and MRF4 mRNA expression).…”

“…Shortness of hatching windows when eggs were set with the small end down would lead to improved growth performances through early access to feed, which is crucial for post-hatch performances ( Gaglo-Disse et al, 2010 ; Wang et al, 2014 ). In addition to short hatching windows, Guo et al (2021) recorded an increase of goslings of high quality with a proper turning angle. According to Tona et al (2003a) , day-old chick quality and relative growth up to 7 days as well as slaughter performance are positively correlated ( Figure 4 ).…”

The chicken hatching egg is a self-contained life-supporting system for the developing embryo. However, the post-hatch performance of birds depends on several factors, including the breeder management and age, egg storage conditions and duration before incubation, and the incubation conditions. Studies have determined the effect of incubation factors on chick post-hatch growth potential. Therefore, chick physical quality at hatch is receiving increasing attention. Indeed, although incubation temperature, humidity, turning and ventilation are widely investigated, the effects of several variables such as exposure of the embryo to high or low levels, time of exposure, the amplitude of variations and stage exposures on embryo development and post-hatch performance remain poorly understood. This review paper focuses on chick quality and post-hatch performance as affected by incubation conditions. Also, chick physical quality parameters are discussed in the context of the parameters for determining chick quality and the factors that may affect it. These include incubation factors such as relative humidity, temperature, turning requirements, ventilation, in ovo feeding and delay in feed access. All these factors affect chick embryo physiology and development trajectory and consequently the quality of the hatched chicks and post-hatch performance. The potential application of adapted incubation conditions for improvement of post-hatch performance up to slaughter age is also discussed. It is concluded that incubation conditions affect embryo parameters and consequently post-hatch growth differentially according to exposure time and stage of exposure. Therefore, classical physical conditions are required to improve hatchability, chick quality and post-hatch growth.

“…In addition, egg characteristics are influenced by the age of geese of the parent stock and the laying period [28]. One of the technological methods of waterfowl egg incubation is to turn the eggs during incubation for an even distribution of temperature on the embryo [26,29]. Changes in the mRNA expression of regulatory genes of muscle development (e.g., [30,31]), such as myogenic factor 5 (MYF5), myogenic differentiation 1 (MYOD1), myogenin (MYOG), and myogenic factor 6 (MYF6, or MRF4), along with the activation of the genes for paired box 3 (PAX3) and paired box 7 (PAX7), explain the enhanced growth and development of limb muscles using a wider angle of rotation of the eggs during incubation.…”

Herewith, the development of goslings and the secretion of hormones of the somatotropic and thyrotropic axes are also intensified [29,32]. In addition, when calibrating eggs by weight in various poultry species, it was shown that the hatching qualities of the medium weight (modal) class were higher than those of small and large eggs (e.g., [33,34]).…”

One of the major problems impeding the sustainable development of goose production is low egg hatchability. Thus, it is imperative to develop more efficient ways to improve the hatching qualities of goose eggs. The present study aimed to investigate the effects of changes in the temperature regime of incubation on the availability of vitamins A (retinol) and E (α-tocopherol), as well as important elements of antioxidant protection in embryos and goslings. The initial heating of eggs at temperatures of 39 and 39.5 °C during the first 24 or 36 h was used as the main factor influencing goose embryo development. The dynamics in the content of antioxidant retinol and α-tocopherol were analyzed in the liver of embryos and goslings (up to 9 days of age) using the standard regime of incubation (at 38 °C) and the prior heating of eggs (at 39 °C and 39.5 °C) in the first 24 and 36 h of incubation. The obtained results provided new information about the effect of the initial heating of eggs on the function of antioxidants in the gosling’s body. It was confirmed that the age-related changes of retinol and α-tocopherol levels in goslings are similar to those found in chicks, ducklings, and turkey-poults. In addition, the effect of an egg’s weight on hatchability was established, with the hatchability of eggs in the medium weight class being higher than that of smaller and larger eggs. The efficiency of the redistribution of retinol from the yolk to the liver in day-old goslings was higher by 6% when exposing eggs to a temperature of 39.5 °C for 36 h. The initial heating regime at 39.5 °C led to an increased hatch of goslings, and to the evenness of their hatch from eggs of different weights, approaching the hatch values of the medium class. Overall, the α-tocopherol concentration in the liver of embryos and goslings, using the starting heating of eggs, was higher than that with the standard temperature mode of incubation. At the same time, the hatch rate of goslings increased by 9–13%, and the hatchability of eggs by 10–16%. For use in the practice of hatcheries and breeding poultry farms, it is recommended that goose eggs are heated for 36 h at 39.5 °C.

“…Incubation phase is a critical stage in the life cycle of poultry, which covers the phase from the start of embryogenesis to the beginning of the young bird stage or birth ( Gilbert and Knisely, 2000 ) and play an important role in the skeletal muscle growth and final meat quality in poultry ( Nyuiadzi et al, 2020 ; Guo et al, 2021 ). Skeletal muscle is the dominant component of poultry meat.…”

The Role of Incubation Conditions on the Regulation of Muscle Development and Meat Quality in Poultry

Muscle is the most abundant edible tissue in table poultry, which serves as an important source of high protein for humans. Poultry myofiber originates in the early embryogenic stage, and the overall muscle fiber number is almost determined before hatching. Muscle development in the embryonic stage is critical to the posthatch muscle growth and final meat yield and quality. Incubation conditions including temperature, humidity, oxygen density, ventilation and lighting may substantially affect the number, shape and structure of the muscle fiber, which may produce long-lasting effect on the postnatal muscle growth and meat quality. Suboptimal incubation conditions can induce the onset of myopathies. Early exposure to suitable hatching conditions may modify the muscle histomorphology posthatch and the final muscle mass of the birds by regulating embryonic hormone levels and benefit the muscle cell activity. The elucidation of the muscle development at the embryonic stage would facilitate the modulation of poultry muscle quantity and meat quality. This review starts from the physical and biochemical characteristics of poultry myofiber formation, and brings together recent advances of incubation conditions on satellite cell migration, fiber development and transformation, and subsequent muscle myopathies and other meat quality defects. The underlying molecular and cellular mechanisms for the induced muscle growth and meat quality traits are also discussed. The future studies on the effects of external incubation conditions on the regulation of muscle cell proliferation and meat quality are suggested. This review may broaden our knowledge on the regulation of incubation conditions on poultry muscle development, and provide more informative decisions for hatchery in the selection of hatching parameter for pursuit of more large muscle size and superior meat quality.
