The Bulgarian Dairy Synthetic Population (BDSP) is the most numerous breed in Bulgaria. FABP3 gene plays a crucial role in hormone action and cellular functions. The aim of the study is to investigate the relationship of FABP3 gene polymorphism with litter size in ewes of BDSP. This experiment involved 110 ewes from the herd of the Agricultural Institute-Shumen. Ewes were selected by birth type (singles, twins, triplets) and with records of the number of lambs born from a minimum of two consecutive lambing. The average number lambing of ewe is 3.94. Two alleles and two genotypes were identified in the studied animals in exon 2 of the FABP3 gene (SNP3) by the PCR-RFLP technique with BseDI endonuclease. The association of FABP3 gene polymorphism with total litter size and litter size depending on the parity and type of birth of ewes was studied by the one-way analysis model of variance ANOVA. A certain superiority was observed in the examined traits of the animals born as twins and triplets, but no significant differences were found between the individual groups.
