What is The breeding program of the Segureño meat sheep breed about?

Segureño sheep breed count with more than 1.7 millions of breeding females distributed in the southeastern Spain, always linked to family exploitations with a mean size of 300 animals. These animals are specialized in the meet production in hard conditions, so they are collaborating in the fixation of people to land in a depressed region of Spain. Anyway the good work of ANCOS (Breeders Association) have got the development of meet control programs, artificial insemination circuits; and a Breeding program exemplar in Spain. The Breeding program is taking into account prolificacy and weight and daily gains at physiological points such as birth, weaning and slaughtering. The productive files count with 282,961 lambing from 97,481 ewes (2.91 lambing /ewe) to work with prolificacy; on the another hand we have 27,864 valid weights from 7,428 lambs to work with weights and daily gains. The pedigree file is formed by 99,635 individuals (2,154 rams) distributed into 220 flocks. The pedigree has been contrasted with genealogical molecular test, reaching values of 89% of right assignation of parents. We used the MTDFREML package to analyze these data by mean of an animal model with repeated
