花畜鬥雞產蛋性能與繁殖性能之探討
Investigation of the reproduction and egg production performances of the HLAPS cockfighting
摘要
本試驗旨在探討經多世代繁殖選育之花畜鬥雞（Hualien Animal Propagation Station Cockfighting，以下簡稱HLAPS Cockfighting），其選育期間種雞產蛋性能與繁殖性能之結果。於2017－2021年間，共計蒐集306隻種母雞與114隻種公雞性能檢定資料顯示，花畜鬥雞產蛋性能初產日齡介於173－187天，初產體重平均介於2,920－3,126公克，初產蛋重介於38－42公克，40週齡產蛋率介於48－61%，40週齡產蛋數介於58－64枚，50週齡產蛋率介於46－56%。在公雞繁殖性能方面，30週齡種公雞的平均精液濃度5.25－7.04 × 10^9/mL、精子活力75.8－86.2%、精子存活率61.5－82.8%。而33－35週齡種母雞受精率為52－88%，種蛋出雛率為39－68%，花畜鬥雞於2021年受精率與出雛率分別為88%與68%，育成率也達95%。資料顯示經由選育出的花畜鬥雞種雞的產蛋性能與繁殖性能已有改進，其公雞可作為民間生產優質鬥雞母之公系種雞，而結果可作供研究臺灣鬥雞性能之基礎，並提供臺灣鬥雞種雞場種原擇選之參考，成為未來進行研究之依據，了解性狀之改進情形。

The purpose of this experiment was to study the reproduction and egg production performance of Taiwan HLAPS cockfighting during the breeding period, which came from the Hualien Animal Propagation Station. A total of 306 breeding females and 114 breeding males were collected in this selection. The results showed that in terms of egg production performance at 40 weeks of age. The body weight at first egg, age at first egg, and egg weight at first egg of the cockfighting hens were 2,920-3,126 g, 173-187 days, and 38-42 g. At 40 weeks of age, the laying eggs rate was 48-61%, hens were laying 58-64 eggs. At 50 weeks of age, the laying eggs rate was 46-56%. The body weight at first egg and age at first egg of the cockfighting hens were 2,920 g and 178 days in 2021, respectively. In terms of reproductive performance, semen quality of 30-week-old HLAPS cockfighting roosters was analyzed. The concentration of sperm was 5.25-7.04 × 10^9/mL, the sperm motility was 75.8-86.2% and the sperm survival rate was 61.5-82.8%, respectively. The rate of fertilization and the hatching at 33-35 weeks of age were 88% and 68%, respectively. Meanwhile, the breeding rate of 22-weeks was 95% in 2021. It is shown that the breeding birds of the HLAPS cockfighting cock have excellent egg-laying performance and reproductive performance. Their performances became steadily. This data will become the basis for studying the performance of Taiwan cockfighting and provide a reference for the selection of the original quality of Taiwan cockfighting breeding farms. It can also be used as a basis for researching to understand the improvement of the herd of Taiwan cockfighting in the future.
