中文摘要 | 本調查的目的為利用統計分析方法,評估臺灣地區白肉雞生產性能,作為業者改進 之參考。統計資料係按月蒐集臺灣地區白肉雞契養戶之生產資料(1997年1月至12月),共 1,580批次,計39,650,062隻。依其出售月份計算,區分為4季,顯示白肉雞各項生產性能, 如:飼養日齡、育成率、出售體重、飼料換肉率、生產指數、飼料造肉成本等,並探討各生產 性能間的關係。分析結果顯示:1997年平均育成率91.49±5.86%,飼養日齡41.62±2.18日, 出售醴重1.89±0.10 kg,飼料換肉率1.92±0.15,生產指數220.11±36.06,飼料造肉成本 12.88±1.18元/0.6kg。育成率仍以第4季最佳,而第3季較往年同期有顯著提升。飼養日 齡、出售體重、飼料換肉率與往年比較差異不大。生產指數因受育成率影響,以第4季最佳, 第1、2季較差。飼料造肉或本較1996年下降0.3元/0.6kg,較前4年平均仍高出1.26元 /0.6kg。 |
英文摘要 | The purpose of this study was to assess broiler production performance in Taiwan for the year 1997. The data were collected monthly from contract farms from January to December of 1997. The total flocks were 1,580 with 39,650,062 broilers. Monthly sales were divided into 4 seasons to present production performance efficiencies, such as marketed age, livability, live weight, feed conversion, production index, cost over feed, and their relationships. The results were average livability 91.49±5.86%; marketed age 41.62±2.18 days; live weight 1.89±0.10 kg; feed conversion (feed/gain) 1.92±0.15; production index 220.11±36.06; cost over feed 12.88±1.18 NT/0.6 kg, respectively. The livability in the 4th season was still the highest and the production in the 3rd season was improved significantly as compared with the previous years. Marketed age, live weight of broilers and feed conversion were similar with that of previous years. The production index was better in the 4th season and lower in the second and 3rd seasons. Cost over feed decreased by 0.3 NT/0.6 kg, as compared with 1996, but increased by 1.26 NT/0.6 kg as compared with 1993-1996. |
