本試驗的目的是對1頭賓朗公豬(U)與7頭藍瑞斯女豬(L)交配所生之7胎56頭雜交一代(LU) 仔豬，應用生長性能測定與基因型篩檢方式，以瞭解其遺傳特質。雜交一代(LU) 仔豬公(N=11)與母(N=19)的150日齡日增重、飼料效率及背脂厚度，分別為0.52 kg與0.61 kg、2.55與3.11及1.78㎝與2.23㎝，其性能介於賓朗豬與藍瑞斯之間。將豬緊迫基因、多產基因及18個微衛星型遺傳標記所得到的遺傳標記交替基因分布頻率以套裝軟體BIOSYS分析，其結果顯示藍瑞斯女豬的平均異質性為0.49、賓朗公豬為0.30、雜交一代仔豬則為0.55，賓朗豬與藍瑞斯毛色皆為白色，而其雜交一代少部份仔豬有黑斑出現。
關鍵語：飼料效率、微衛星型標記、遺傳特性

The purpose of this study was to understand the genetic characteristics of seven litter hybrid pigs, bred from one Peinan boar and seven Landrace sows, by analysis of growth performance and genotype data. The average daily gain from birth to 150 days(ADG), feed efficiency (FE) and average backfat (BF) for hybrid boar and gilt were 0.52 kg and 0.61 kg, 2.55 and 3.10, and 1.78㎝and 2.23㎝, respectively. The growth performance of hybrid pig was between Peinan pig’s and Landrace pig’s. Allele frequencies of porcine stress gene, estrogen receptor (ESR) gene and 18 microsatellite markers were investigated and analyzed by the BIOSYS software package . The results showed that the mean heterozygosity of Landrace gilt, Peinan boar and hybrid pig were 0.49, 0.30,and 0.55, respectively. Peinan boar and Landrace sows are all white in color. In this study, some pigment spots were observed on the skin of F1 hybrids.
Key Words: Feed efficiency, Microsatellite marker, Genetic characteristics
