大白母系种猪优良性状的选育进展
Breeding progress of large white pig matriline with desirable characteristic
摘要
Abstract
In this study, the large white pig core group which consisted of eight independent bloodlines with ten boars and fifty sows was established. On-farm testing, individual breeding value estimated by GBS breeding software and the comprehensive selection in-dex were used to select generation core group. After four years breeding, the year average corrected weight of boars increased 7.90%, sows increased 7.41%, which reached the significant difference (P<0.05). The age up to 100 kg weight was shortened to 1.176 day and the average corrected backfat thickness of boars and sows dropped by 9.54% and 7.54% respectively, which reached the significant difference (P<0.05%).The breeding value of backfat thickness up to100 kg weight decreased 0.159 mm, the total number born in-creased year by year, the breeding value of number increased 0.029. Comprehensive selection index increased 3.84%.The results showed that specialized matriline of large white pig with high performance could be obtained through building excellent core breeding group and using hybridization between different strains.关键词
