“…Genetic analysis of these cattle through molecular markers [2] showed that this population can be considered as a breed. This population shows the greatest degree of genetic similarity (> 0.10) to Iberian breeds such as Berrenda Colorada, Pajuna, Negra Andaluza and Canaria.…”

“…As a result, the number of this Creole population has been decreasing drastically. In spite of this, the existence of small and heterogeneous nuclei of Creole cattle is still reported in some remote places, such as the Southern Region of Ecuador (SRE) bordering on the north of Perú [2]. Due to their phenotypic and genotypic characteristics they have managed to survive and develop in these complex environments, acquiring their own characteristics that have allowed them to adapt and thrive in this hard habitat.…”

The breeding of creole cattle from the southern region of Ecuador, also known as Criollo Lojano, is a source of economic support and work for the communities located in the remote areas of the Andes mountains in this region. These cattle are grouped into four biotypes based on their phenotypic characteristics: Negro Lojano, Encerado, Colorado, and Cajamarca or Pintado. This study analyzes the morphometric variability of these creole cattle using least squares means (LSM) and restricted maximum likelihood Restricted Maximum Likelihood (REML) variance components. The evaluation parameters used to characterize these cattle were live weight plus 15 morphometric characteristics and nine morphometric indexes. The measurements came from 151 adult animals (28 male and 123 females). With the exception of Height at Withers (P = 0.06), the other morphometric characteristics do not show significant difference among these creole biotypes. Sexual dimorphism was found in live weight, thoracic circumference, height at withers, chest width, length of thorax, length of body, depth of thorax, depth of abdomen, length of head, and length of horns (P < 0.05). The adult Creole Lojano has an average live weight of 288 ± 12.9 kg (mean ± standard error), The Cephalic index is 45.6, the Corporal index is 115.9, the Pelvic index is 90.5, the Thoracic index is 58.3, the Proportionality index is 62.6, the Thoracic Capacity index is 2.1, the Lower Leg–Thoracic index is 9.9, the Transverse Pelvic index is 34.7, and the Pelvic Length index is 38.4. This creole bovine breed presents 4 biotypes that are similar; there are differences in the analysis with respect to sex (males are higher in 10 of the 16 characteristics analyzed); and on the basis of the indexes, this animal is small, has a triangular head, is longilinear with a long and narrow hip. It is a dual-purpose milk type with the exception of the Colorado biotype which is a dual purpose meat type.

Cattle are our most important livestock species because of their production and role in human culture. Many breeds that differ in appearance, performance and environmental adaptation are kept on all inhabited continents, but the historic origin of the diverse phenotypes is not always clear. We give an account of the history of cattle by integrating archaeological record and pictorial or written sources, scarce until 300 years ago, with the recent contributions of DNA analysis. We describe the domestication of their wild ancestor, migrations to eventually all inhabited continents, the developments during prehistory, the antiquity and the Middle Ages, the relatively recent breed formation, the industrial cattle husbandry in the Old and New World and the current efforts to preserve the cattle genetic resources. Surveying the available information, we propose three main and overlapping phases during the development of the present genetic diversity: (i) domestication and subsequent wild introgression; (ii) natural adaptation to a diverse agricultural habitat; and (iii) breed development.

“…In Peru, Creole bovine are of great interest for the rural farmers' economy in Andean region, supplying food (meat and milk), profits, among others [15,16]. Although, introduction of specialized breeds such as Holstein, Jersey, Brown Swiss, Angus, Brangus, Simmental, intends to increase productivity, they are more susceptible to harsh environmental conditions.…”

Bovine breeding began in Peru more than five centuries ago; since then, adaptation has started. Nowadays, Creole cattle are part of economic activities of Peruvian farmers, as they supply food and profits, among other things, for families in Andean region. Creole cattle have many strengths such as resistance to diseases, low nutrient requirements and easy adaptation to different levels of altitude and environmental conditions. However, even with all these attributes, they are not valued within production systems. Moreover, these valuable genetic resources are disappearing gradually in Perú. For this reason, this study aims to characterize the zoometry of Creole cows from the Southern Amazonas region of Peru. Biotype classification was performed by hierarchical cluster and multivariate factors analysis. Qualitative traits were analyzed with descriptive statistics and Duncan’s test (α = 0.05) was used to compare means among groups. Associations between qualitative traits were determined with Chi-square. We distinguished three biotypes of Creole cows with characteristics for meat and milk production. This information is helpful for future conservation programs for Creole cattle.
