German Angora does were inseminated with either Pannon White (N) or heterospermic (N plus A) or Angora (A) rabbit semen to compare the reproduction and growth traits of 54 NxA, 53 (N plus A)xA and 65 AxA matings. The kindling rate was 59.3, 58.5 and 47.7 per cent, resp., the value of total born per litter averaged 7.09, 6.36 and 6.19, litter size at 21 days of age 5.73, 5.97 and 4.89, and litter weight at 21 days 1739, 1700 and 1446 g. In the (N plus A)xA group the ratio of NA and AA offspring at 21 days of age was 70.1 per cent and 29.9 per cent, which differed from the expected 1:1 distribution (P less than 0.05). Rabbits were weaned at 42 days of age. For 91 NA from NxA, 74 NA and 30 AA from (N plus A)xA, and 94 AA offspring from AxA mating combinations, the body weight averaged 317, 287, 288 and 303 g at 21 days and 1054, 993, 869 and 908 g at 42 days, and 2004, 1891, 1610 and 1594 g at 70 days, and the daily weight gain between 3 and 6 weeks of age was 35.0, 33.6, 27.7 and 28.8 g and between 6 and 10 weeks of age 33.4, 32.1, 25.4 and 24.7 g, resp. It was concluded that the Angora semen disadvantageously influenced the fertility and litter size.
