Criollo Limonero cattle (Bos taurus) is an endangered bovine breed reared under the dry tropical areas of Venezuela. So far, the inbreeding and genetic diversity values of the Criollo Limonero cattle have not been assessed after more than five centuries of environmental adaptation. The main aim of the present research was to carry out a detailed analysis of the demographic status, reproductive performance, inbreeding and genetic diversity of the endangered Criollo Limonero dairy cattle using official genealogical information. Six populations were considered: historical population (individuals
