title: Litter parameters and spontaneous abnormalities in Himalayan rabbits.
abstract: A joint study was undertaken in three testing facilities to evaluate cumulative background data of Himalayan rabbits. All litters were derived from control does. The conception rate was high (84.0-95.1%) but the average numbers of corpora lutea (7.9-8.7), implantation sites (6.5-7.5) and viable fetuses (5.8-6.9) were somewhat lower than that of most other strains of rabbit. Altogether 90 malformed fetuses (1.12%) and 425 fetuses with variations (5.27%) occurred among 8,060 virable fetuses.
