摘要

The present study aimed to evaluate some genetic markers of blood proteins and their relationshipto some reproductive parameters in Purebred Arabian mare. Breeding records and data of Arabian mares havebeen collected and analysed regarding age of mares, number of parity, number of male parity, number of femaleparity, interval to foaling heat, interval to conception, length of gestation period with female/male fetus, lengthof gestation period with male fetus, overall length of gestation period in both fertile and low fertile mares. Genefrequencies and typing of both fertile and low fertile mare were done. Distribution of genotypes andfractionation of blood protein loci (Albumin (Al), Post albumin (Pal), Pre albumin (Pr), Transferrin (Tf), -globulin (F 2),,Estrase (Es), vitamine D binding protein(Gc)) were carried out. Results elaborated that theaverage age (years), average interval to foal heat(days) and the average interval to conception(days) were9.78±1.4, 15.6±6.41 and 54.24±7.8d for fertile mares while it was 13.65±2.63y, 38±18.54 and 155.5±8.5 for low fertilegroup. It was also found that the average length of gestation was significant (P<0.05) longer in fertile mares(331.6±5.22) than in low mares (322.07±4.14) while Fertility index was significantly (P<0.05) higher in fertile mares(75.67±3.96) than in low fertile mares (61.84±5.23). Results also showed high frequency of Al J, of PtrR, EsG, GcFgenes in fertile Arabian mare while low fertile mares were characterized by high frequency of ofPrN, F B and2EsGgenes. Results also showed significant (P<0.05) positive correlation of PrS and negative correlation of PrNgene marker with number of male parity. Al F was positively correlated with progesterone level, TfDgene markerwas positively correlated with age and interval of conception, while it is negatively correlated with length ofgestation in both male and female feti. TfO was positively correlated with the fertility index and predominatedin mares having stable gestation in both and male and female feti. PalSwas dominant in mares having highprogesterone level while PalDwas dominant in those having low progesterone level and low fertility index. EsGwas positively correlated with long gestation period with male feti while EsHshowed the reverse. This studyconcluded that the higher fertility of Purebred Arabian mares is tightly associated with high prevalence of TfO,PalSand AlFgene markers.
