中文摘要 | 本試驗之主要目的是建立客觀方法來評估本省雷克斯兔毛皮品質,以取代傳統的主觀評估方法。兔毛皮品質評估項目計有毛皮成熟度、剛毛量、毛密度及毛長度,評估方式係採毛密度測量儀、Image-pro Plus 2.0電腦影像處理分析軟體以及專家或評級員的主觀評級等。本研究係採用1993年畜試所146隻擬上市之雷克斯兔送往雲林縣養兔生產合作社屠宰,屠宰前先由合作社評級員評定等級,依優劣順序分為A、B、C三個等級(即市場交易評級)。屠宰後剝下的兔毛皮,由法籍專家Thebault先生分別依毛皮之成熟度、毛長度及剛毛量等性狀加以評估(INRA目測評級法)。由劣至優分為1~5五個等級,並使用毛密度測量儀(Compacimeter)測量毛密度(測量法)。此外,並使用Hi8攝影機拍攝後,以電腦數位影像處理分析軟體(Image-pro Plus 2.0分析兔毛皮之成熟度(影像法)。隨後則後用Pearson和Spearman相關係數比較本試驗之各種評估方法之相關性。結果顯示:Thebault先生目測評級兔毛皮成熟度與影像法分析結果有極顯著相關(r=0.68,P<0.0001)。另外,雲林縣養兔生產合作社評級員評級之兔毛皮品質等級與法籍專家應用測量儀測定之兔毛密度與目測剛毛量,兩者結果均極為一致性。 |
英文摘要 | This study was to set up a objective measurement for pelt quality instead of the traditional subjective evaluation system used for Rex rabbit in Taiwan. The criteria of pelt quality included in the study were maturity, bristle quantity, compactness and coat length. The evaluation was made by gauge apparatus (Compacimeter), Image-pro Plus 2.0 software or/and the subjective grade classified by specialist(s) or grader(s). One hundred forty-six Rex rabbits were sent to Yulin County Rabbit Production Cooperative (YCRPC) for grading by YCRPC's grader(s) before slaughtered in 1993. The subjective market grades included three categories, grades A, B and C representing the best, the average and the worst quality, respectively. Mr. Thebault (INRA's specialist) then evaluated the maturity, hair length and bristleless of fur quality and classified it to one to five grades from the worst to the best pelts. Furthermore, compacimeter was used by Mr. Thebault for measuring the compactness of pelts. Also, Hi8 camera recorder and Image-pro Plus 2.0 software were used to analyze the maturity of pelts. The Pearson and Spearman correlation coefficients were used to compare the evaluation methods used in the study. The results showed that there was significant correlation between maturity obtained by Mr. Thebault's evaluation and by image processing (P<0.001). Also, the grade of fur quality obtained by YCRPC's grader(s) was significantly consistent with results of compactness from compacimeter and of bristle quantity from INRA's specialist for plets. |
