title: Cytogenetic evaluation of boars with a low prolificacy: two new types of chromosome translocation.
abstract: Using the National Program for Sow Herd Management, two hypoprolific boars have been identified. The first one, a Large White, had produced on an average 7.2 piglets per litter in 24 litters. The second one, a Pietrain, had produced 6.11 piglets per litter in 28 litters. These animals are carrying two new chromosome translocations involving chromosomes 1 and 15 and 4 and 15, respectively. The animal production consequences of the chromosome translocations are discussed.
