Genetic evaluation of the lactational performance in Giza White rabbits and its relation with preweaning litter traits

Khalil, M. H.

Data were analysed on 325 litters from 40 sires and 115 dams. Kidding interval averaged 48.8 days, days open 17.9 days, litter size at birth 6.1, number of liveborn young per litter 6.0, litter size at weaning 4.7, litter weight at 21 days 1376 g, preweaning mortality 38.7%, and 35-day milk yield 3493 g. Days open, kidding interval and litter size traits were significantly affected by year-season and parity.
