Phenotypic and genealogy date of Siboney de Cuba cows from 1984 to 2016 calving years was used. The goal of this study was to estimate the parameters and breeding values (VG) of production, reproduction and longevity traits. Besides to construct selection index (IS) using principal componente (CP)...

Abstract

Purpose: Canine primary closed-angle glaucoma (PCAG) is a complex disease caused by multiple genetic factors. A c.590 G >A variant in OLFML3 was recently reported to be a candidate for pectinate ligament abnormality (PLA) and PCAG in the Border Collie. We investigated the association of this...
