【摘要】 对齐卡配套系兔产肉性能及部分品种特性的测定，显示该兔具备良好的产肉性能。在三个品系（Ｇ、Ｎ、Ｚ）中，Ｇ、Ｎ系兔产肉量和板皮厚度优于Ｚ系。成年Ｇ、Ｎ兔全净膛屠宰率５４％～５５％，肉骨比６．３～６．８：１，胴体长４５．５厘米。Ｇ、Ｎ系兔板皮重量占胴体的３２％以上。４月龄Ｎ、Ｚ系兔屠宰率４８％左右，肉骨比５．２６～５。７９：１，胴体长３６厘米。Ｇ系兔外貌最大特点为耳长大（１６～１８厘米），宽８～９厘米，体长４５～６０厘米，头围大（１８～２３．５厘米）。Ｎ系兔耳长１１．６～１３厘宋，耳宽６．６～７厘米，头围１８～２２厘米，体长４１～５０厘米。Ｚ系头型、体躯清秀，头围１７～２０厘米，体长４１～４８．５厘米。三个品系染色体核型都为２ｎ＝４４条，Ａｇ－ＮＯＲ定位于１３、１６、２０、２１号染色体上，Ａｇ－ＮＯＲ均数分别为Ｇ系４．０３、Ｎ系１．９５、Ｚ系２．９８。更多还原

【Abstract】 The meat production and some other species traitS of ZIKA arbbits were presented inthis study.Among the three strains(G,N and Z),the carcass percent of the adult G and Nstrains was 54%～55%;and the ratio of meat:bone was 6.3～6.8:1;the length of theircarcass was 46～50cm.For the Z strain,carcass percent was 50%and ratio of meat:bone 5.63:1,Carcass length 45.5cm.The carcass percent of N and Z rabbits at 4 month was about48%,ratio of meat:bone was5.3～5.8 and carcass length 36 cm.The results showed thatthe rabbits were good meat producer.The leather weight accounted for over 32%of their carcass for G and N strains.Theleather quality of G and Z was higher than that of Z strain.The G strain was characterizedwith big ears(16～18cm long and 8～9cm wide).It had 45～60cm body length and a bighead(18～23.5cm cycle length).The ear length of N strain was 11.6～13cm and its widthwas 6.6～7cm,head cycle 18～22cm and body length 41～50cm。The outside of head andbody of Z strain was clear,with a head cycle 17～20cm and body length 41～48.5cm.The chromosome of the three strains was 2n=44,Ag-NORs located at 13,16,20 and21 on their chromosornes.The Ag-NORs averaged 4.03,1.95 and 2.98 respectively for G,N and Z strains.更多还原
