Saito, S. (Fukui Prefectural Livestock Experiment Station (Japan)) | Ishikawa, T. | Murata, F.
In this study, we investigated about reproductive trait of LW * B (L:Landrace, W: Large white, B:Berkshire) and LB * D(L:Landrase, B:Berkshire, D:Duroc) to develop 'New fukui pork'. The number of first litter of LB * D was less than these of LW * B and 'Fukui pork (LW * D)'. Total body weights of LB * D litter was also less than others. Daily feed of testing gilts was increased 500g per head for one week before expected childbirth day. In order to prevent a reduction in birth weight as a result of mating Berkshire. As a result, the average litter size of LW * B was as large as 'Fukui pork(LW * D)' and LB * D was the largest.
