  • Two experiments were conducted on 132 fertile females of New Zealand White (NZW) and Californian (Cal) rabbits.The first experiment aimed to study the mating frequency and/or spermatozoa number effects on conception rate (GR), litter size and litter weight at birth. Six groups were designed to cover all possible combinations between O, 1 or 2 matings of vasectomized buck (SB) and 1 or 2 matings of fertile buck. Each group consisted of 6 NZW and 6 Cal does, for a total of 72 females. The studied characteristics were insignificantly affected by groups or breeds. The overall means were 79.2 % GR, 6.5 youngs per litter and 294 g litter weight at birth.The second experiment was conducted to determine the possibility of using SB as ovulation inducer in artificially inseminated rabbit (Al). Equal numbers of 15 fertile females Two experiments were conducted on 132 fertile females of New Zealand White (NZW) and Californian (Cal) rabbits.The first experiment aimed to study the mating frequency and/or spermatozoa number effects on conception rate (GR), litter size and litter weight at birth.
