中文摘要 | 發展休閒觀賞用豬種可間接地推動畜產休閒化。在1989年選用蘭嶼種公豬2頭與 配6頭杜洛克種母豬;及以3頭杜洛克公豬與配5頭蘭嶼母豬,採人工授精方式。杜洛克與蘭 嶼豬雜交後裔仔豬於8週齡時檢視體色,不論正反雜交的仔豬身體兩側均呈現黑色橫條紋與 紅棕色橫條紋交複排列型態。這類具有棕黑條紋的仔豬被選留為種畜,並採半同胞配種而產 下棕白相間條紋的仔豬,這類棕白相間條紋的仔豬被稱為迷彩豬,棕白相間條紋不能表現到 性成熟期。在1992年改以一年一世代6公18母做為棕白條紋體色的選育族群,進行後續四 個世代的選育試驗。試驗結果,第三代迷彩豬種母豬平均每胎產6.00±2.10頭活仔豬,第四 代仔豬呈現棕白條紋者有72.8%,較上一代的25.3%增加幾近三倍,而在第六代增加到100%。 迷彩豬棕白條紋已能表現到性成熟期,推測棕白條紋為一隱性基因。迷彩豬選育族群的經濟 用途上,除因其體型小與體色有特性,提供為休閒觀賞用豬種極具潛力外,亦可供醫學研究 用實驗豬。 |
英文摘要 | A new miniature pig for ornamental purpose was developed. In 1989, two Lanyu boars were used to mate six Duroc sows; and semen collected from three Duroc boars was used to inseminate five Lanyu sows. Their hybrid piglets were examined for coat color at eight weeks of age. Piglets exhibited longitudinal stripes from head to tail. Several brown stripes and black stripes appeared side by side on piglets from either Lanyu x Duroc crossing or Duroc x Lanyu crossing. Those piglets with brown-black stripes were then selected as breeding stocks and bred by half sib relation to produce brown-white stripping piglets, but the brown-white stripping faded at puberty. Brown-white stripping piglets were named as the Mitsai pig. A selection program for brown-white stripping was launched in 1992 with six male and 18 female pigs for each generation and for each year. Experimental results were as follows: The third generation (F3) of Mitsai sows produced 6.00 ±2.10 piglets born alive per litter and 72.8% of F4 piglets exhibited brown-white stripes as compared to 25.3% in F3, which increased almost three times. All F6 piglets exhibited brown-white stripes. Brown-white stripes exhibited and remained so even when pigs reached the mature age. The gene for brown-white stripping was postulated to be a recessive gene. For the economical usage, the Mitsai line with characteristics of miniature type and coat color could be used as ornamental pig for recreation. It could also serve as a laboratory animal for biomedical research. |
