Abstract:
Ogye, an indigenous Korean chicken breed has entirely black external features and internal organs. White Leghron, an transboundary breed has white color features as opposed to Ogye. We make crossbreed (Ogye x White Leghorn) to investigate how the phenotype appeared in F1. In F0, 5 females and 1 male were selected for each parental type; 1) Ogye(♂) x White leghorn(♀), 2) White leghron(♂) x Ogye(♀). We A total of 321 individuals of F1 were made through artificial insemination. We measured body weights at birth, 8 weeks, 16 weeks, 24 weeks, and 32 weeks of age. In 1) type females, the average of body weight at each period was 39.04±0.32, 613.18±6.86, 1149.37±7.76, 1463.97±13.25, 1718.02±14.83 respectively. In 2 type females, that was 30.57±0.21, 543.19±7.54, 1069.63±12.92, 1410.06±10.80, 1527.53±13.73. The P-value values for each period were less than 0.05. In 1) type males, the average of body weight at each period was 39.18±0.34, 744.70±7.84, 1579.39±15.76, 2014.63±19.15, 2310.89±20.58. In 2 type females, that was 30.71±0.24, 683.75±9.51, 1419.79±15.76, 1800.00±18.88, 2064.79±19.68. The P-value values for each period were also less than 0.05. In the case of feather color, it was generally white, but black spots appeared only in females produced in type 1). Comb and beak color was generally also red, but black appeared only in in females produced in type 1). From these results, it can be estimated that paternal factors such as weight and appearance are greatly affected, and we plan to investigate the genetic patterns of each trait through F2 construction in the future.
