In the present study 2 new reciprocal translocations are described in two hypoprolific boars. The first one, a Gascon/Meishan boar, has produced a mean value of 7.37 +/- 0.69 piglets, vs 12.41 +/- 0.22 piglets per litter in contemporaries. The second one, a Pietrain/Large-White boar, has produced a mean of 5.42 +/- 0.69 vs 12.41 +/- 0.22 piglets per litter in contemporaries. Each of these animals carries a new chromosome translocation involving chromosomes 6, 8 and 15, respectively. The first translocation seems to be a de novo occurring abnormality. The economic consequences of these abnormalities are discussed. Carrier of the gene HAL, the abnormal chromosomes 6 involved in these translocations are important, and could useful markers in gene mapping and flow cytometry studies in pigs.
在本研究中，描述了两头低产公猪的两种新的相互易位情况。第一头是加斯科尼/梅山公猪，其每窝产仔的平均值为7.37±0.69头仔猪，而同期的仔猪每窝平均产仔数为12.41±0.22头。第二头是皮特兰/大白公猪，其每窝平均产仔5.42±0.69头，而同期每窝平均产仔12.41±0.22头。这两头猪分别携带一种涉及6号、8号和15号染色体的新的染色体易位。第一种易位似乎是一种新生的异常情况。讨论了这些异常情况的经济后果。这些易位中涉及的异常6号染色体携带HAL基因，它们很重要，可能是猪基因图谱绘制和流式细胞术研究中的有用标记。
