Contribution of Lidia cattle breed historical castes to the paternal genetic stock of Spain.
The main objective of this work was to determine whether the five founding castes defined in the Lidia cattle breed actually have an important contribution to the Spanish paternal genetic stock as well as to the paternal genetic origin support. A total of 1300 Bos taurus male individuals were genotyped for five microsatellites (INRA189, UMN0103, UMN0307, BM861 and BYM1) and one indel (ZFY10). Microsatellite and indel alleles were combined into haplotypes, identifying a total of 38 haplotypes, 11 of them belonging to haplogroup Y1 and 27 to haplogroup Y2. Ten different haplotypes were found in the Lidia cattle breed, with five being exclusive to this breed. Our results agree with different male genetic stocks in the Lidia breed: one hypothetically representing the ancient Iberian bovine genetic stock (Gallardo, Navarra and Cabrera castes and some encastes from Vistahermosa) and a second one that is the result of the more recent breeding strategy of choosing the most aggressive individuals from traditional herds (including some Vistahermosa encastes and the Vazqueña caste). In terms of conservation, it would be better to not consider this breed as a unit but to consider the caste, or even better the encaste, as the target of putative conservation efforts.
