An Association Study Of Microsatellite And Growth Traits In Boer Goat

Twenty microsatellite loci were selected from the goat linkage map in this study.The microsatellite DNA was amplified using PCR technique to examine the genetic structure and relationship between microsatellite DNA and growth traits including body weight, length,height,chest of birth,weaning and one-year-old.Twenty microsatellite loci analyzed were polymorphic in Boer goat population with all the observed number of alleles,the average effective number of alleles(Ne),an average number of alleles per locus,the average information content(PIC) and average heterozygosis(H) were 193,7.3287,9.65,0.8290 and 0.8478 respectively.Making use of the PROC GLM of SAS we get the result as the follows:(1) 228/228 of INRA011,238/238 and 246/216 of INRA040,193/167 of ILSTS034 were beneficial genotypes to birth weight.145/121 of BM1312,240/240 of INRA011,159/159 of MAF064,281/243 of IDVGA64,159/143 and 161/147 of LSSCV37,162/162 of BMS1248, 153/153 of CSSM047,198/172 of INRA129 were disadvantageous genotypes to birth weight.245/245 of IDVGA64,238/238 of INRA040,193/167 of ILSTS034,136/136 of BM0415 were beneficial genotypes to weaning weight.141/141 of MAF064,238/238 of INRA040,171/171 of CSSM047 were beneficial genotypes to one-year-old weight, 171/153 of CSSM047,311/275 of SRCRSP10 were disadvantageous genotypes to one-year-old weigh.(2) 145/117 of BM1312,238/238 of INRA040 were beneficial genotypes to birth length.240/240 of INRAO11,159/159 of MAF064,281/243 of IDVGA64,198/172 of NRA129 were disadvantageous genotypes to birth length.198/184 of MAF070 were beneficial genotypes to weaning length,136/136 of BM0415,203/203 and 207/207 of MCM527 were disadvantageous genotypes to weaning length.206/206 of CSSM011,238/238 of INRA040,171/171 of CSSM047,303/269 of SRCRSP10 were beneficial genotypes to one-year-old length.(3) 238/238 of INRA040 were beneficial genotypes to birth high.145/121 of BM1312,159/159 of MAF064,281/243 of IDVGA64, 159/143 and 161/147 of LSSCV37,162/162 and 142/142 of BMS1248,198/172 of INRA129 were disadvantageous genotypes to birth high.(4) 238/238 and 246/216 of INRA040,178/178 of INRA129 were beneficial genotypes to birth chest.198/172 of NRA129,161/147 and 159/143 of LSSCV37,159/159 of MAF064,281/243 of IDVGA64 were disadvantageous genotypes to birth chest.245/245 of IDVGA64 were beneficial genotypes to weaning chest,198/184 and 198/198 of MAF070 were disadvantageous genotypes to weaning chest.145/117 of BM1312 were beneficial genotypes to one-year-old chest.This study has a great significance because that it can give a theory gist for genetic marker assistant selection(MAS),Quantitative traits locus(QTL)locating, improvement of Boer goat breeding.
