“…Because the positive association between hens’ body weight and their egg size was reported in chickens [ 67 , 68 ], heavier body weight of the MSTN mutant quail might have an indirect effect on bigger egg size in the mutant group compared to the WT group. Notably, egg weight was bigger in the MSTN mutant group than the WT group even relatively to their body weight [ 69 ], suggesting a potential direct effect on the egg weight by MSTN mutation in addition to the increased body weight of the mutant female quail. However, total egg production (egg weight (g) multiplied by produced egg numbers during the selected periods within the actively laying period) was similar between the two groups, because of lower number of eggs laid by the mutant group than WT group during the period [ 45 ].…”

The myostatin (MSTN) gene is considered a potential genetic marker to improve economically important traits in livestock, since the discovery of its function using the MSTN knockout mice. The anti-myogenic function of the MSTN gene was further demonstrated in farm animal species with natural or induced mutations. In poultry species, myogenesis in cell culture was regulated by modulation of the MSTN gene. Also, different expression levels of the MSTN gene in poultry models with different muscle mass have been reported, indicating the conserved myogenic function of the MSTN gene between mammalian and avian species. Recent advances of CRISPR/Cas9-mediated genome editing techniques have led to development of genome-edited poultry species targeting the MSTN gene to clearly demonstrate its anti-myogenic function and further investigate other potential functions in poultry species. This review summarizes research conducted to understand the function of the MSTN gene in various poultry models from cells to whole organisms. Furthermore, the genome-edited poultry models targeting the MSTN gene are reviewed to integrate diverse effects of the MSTN gene on different traits of poultry species.

“…In birds, the amount of nutrients needed for the chicken embryo is limited in the egg. Kim et al (2023) implies these nutrients cannot be increased or decreased naturally depending on the expression of genes that control egg size.…”

This study aims to determine the effect of in-ovo injection of L-arginine into local chicken eggs on embryo development and chick performance of local chicken. A total of 160 eggs were incubated using semi-automatic incubator with temperature of 37-38C and relative humidity of 55-65%. The injected L-arginine solution has a concentration of 0.5% (m/v). In treatment was divided into 4 groups, the first treatment was without injection (control), the second treatment was the injection of 0.2 mL L-arginine solution 0.5% (m/v)/egg, the third treatment was the injection of 0.4 mL L-arginine solution. 0.5% (m/v)/egg, and fourth treatment was the injection of L-arginine solution 0.6 mL 0.5%(m/v)/egg. The results showed that embryo mortality and hatchability were lower with L-arginine injection treatment than without injection. All treatments showed no effect on extraembryonic fluid absorption, but there was an increase in embryo weight in the injection treatment 0.2, 0.4, 0.6 mL L-Arginine 0.5% /eggs 2,355 g, 2,577 g, 2,705, respectively. In conclusion, an in-ovo injection of L-arginine in local chicken eggs has a good effect (the beneficial effect) on embryo death and embryo performance. Injection of 0.4 ml L-Arginine 0.5% /eggs improved hatchability and Newly Hatched Chick Weight (NHCW).
