The relationship of YAP gene polymorphism with some characteristics of local goats in Al-Muthanna Governorate

This study was conducted at the Postgraduate Laboratory / Department of Animal Production, College of Agriculture, University of Al-Muthanna, from October 12, 2024, to February 12, 2025. A total of 46 three-month-old male local goats were used in the experiment. Blood samples were collected from the animals at the beginning and end of the trial. Some of the partial tests were also conducted at the Marshes Research Center Laboratory, affiliated with Thi Qar University. The study aimed to investigate the relationship between Polymorphism of the YAP (576T>A) gene and the characteristics of local goats reared in Al-Muthanna Governorate. the results of the YAP (576T>A) polymorphism, showed no significant differences in initial body weights and body dimensions. However, there were significant differences (P ≤ 0.05) in final body dimensions, particularly in abdominal girth and breast height, which were 67.88 cm for TA and 71.03 cm for TT genotypes. The TA genotype also had significantly higher breast height than the TT genotype. There were no significant differences in biochemical parameters. Regarding hormones, no significant differences were found except for growth hormone, where the TT genotype was significantly higher (P≤0.05) than the TA genotype. Blood traits showed no significant differences, except for hemoglobin, where the TA genotype was significantly superior (P≤0.05) to the TT genotype.
