中文摘要 | 本試驗之目的在保存中國鵝固有的遺傳型質,並比較其生長及繁殖性能以作為選 育中國鵝品系之依據.在生長的性能方面,白色中國鵝之體高顯著較灰色中心鵝高(p<0.05); 灰色中國鵝之脛長及第八主翼羽長度均顯著較白色中國鵝為長(p<0.01),且灰色中國鵝之胸 寬及恥骨寬亦顯著較白色中國鵝為寬(p<0.01).在體重方面,白色中國鵝之公鵝較灰色中國鵝 之公鵝重6.6%,而品系間(合併性別)無顯著差異(p<0.05),品系與性別間有顯著交感作用 (p<0.05),體長、胸圍、脛長及第八主翼羽方面,品系間有顯著差異,性別間有顯著差異 (p<0.05),品系與性別間無顯著交感作用。1993年兩品系後之比較,在公、母鵝均以白色中 國鵝較灰色中國鵝為重。1994年公鵝以白色中國鵝較灰色中國鵝為重,而母鵝則以灰色中 國鵝較白色中國鵝為重。在繁殖性能方面,5年的產蛋期中,均以第2年產蛋數最多,年產 蛋均以灰色中國鵝較白色中國鵝為多;受精率之差異在品種間無一致性,但以白色中國鵝之 孵化率較灰色中國鵝為高。 |
英文摘要 | The aim of this study was to maintain the gene pool of Chinese geese and to investigate their growth and reproductive performance for breeding purposes. The results showed that the body height and knob of white Chinese geese were better than that of gray Chinese geese (p <0.05). The width of breast and pubic bone, length of tibia and the 8 th primary feather of gray Chinese geese were higher than that of white Chinese geese (p< 0.01). For male white Chinese geese the body weight were 6.6% heavier than those of gray Chinese geese .The body weight differed significantly (p<0.05 ) between sexes but not between lines. The length of body and 8 th primary feather and breast girth differed significantly between sexes but not between lines nor the interaction of line and sex (p>0.05). Compared with the offspring of two lines in 1993,the body weight of white Chinese geese was higher than that of the gray Chinese geese at all growing stages. The egg production of gray Chinese geese were better than those of white Chinese geese, It also showed that the egg production in the 2th year was the best among five years .The fertility rate between lines was not significantly different, but the hatchability rate of white Chinese geese was higher than gray Chinese geese. |
