Caracterización morfométrica y determinación de índices zoométricos de un hato de ganado criollo Blanco Orejinegro (BON) puro, en Pacho (Cundinamarca)

Abstract: Esta investigación fue realizada en Pacho, Cundinamarca, Colombia, donde se evaluaron vacas de la raza criolla Blanco Orejinegro (BON), tomando un total de 18 medidas Morfométricas por animal; con la ayuda de algunos materiales tales como cinta métrica y bastón zoométrico. Estas medidas permitieron la elaboración de una matriz de correlaciones para definir si estos animales responden a un modelo armónico; determinando así la “Caracterización Morfométrica de la Raza”. Según el análisis de correlaciones, se enco… Show more

“…Despite the adverse climatic conditions in the Andean highlands and the low-quality pastures for feeding the cattle in this region [13], the results obtained for the different biomorphometric parameters were superior to those reported in Creole cattle from different environments such as Mexico [4], Ecuador [3], Panama [9], Uruguay [37], Argentina [38], and Peru [35]. However, other studies conducted in other regions such as those reported for Argentine Creole cattle showed similar results to those obtained in the present study with slightly superior values of BL, RW, and RL [8,13], as well as for the Limonero from Venezuela [33] and the Creole Blanco Orejinegro from Colombia [36]. Since the anatomical characteristics of these biotypes have medium-high heritability, this could be improved in specific centers using selection programs as tools for genetic improvement in a few generations [39].…”

“…This fact may be due to the breeding and selection management scheme that is routinely carried out in the experimental research center where the measure values were taken, as well as to genetic factors inherent to the previous selection of the different biotypes [35]. Thus, it could be determined that Creole cattle maintained in the Andean highlands have not been influenced by other foreign breeds, being considered isolated biotypes [36]. It should be noted that the number of individuals was lower in some experimental groups than in others, and therefore, the results obtained might differ if the number of animals per group was increased.…”

“…Las medidas morfométricas de ACa y LCa del criollo mixteco de Oaxaca fueron similares a las reportadas en criollo lojano (ACa 21 ± 0.3, LCa 46 ± 0.6; Aguirre-Riofrio et al, 2019), pero diferentes a las obtenidas en criollo limonero (ACa 26.7, LCa 49.08; Contreras et al, 2012) y blanco orejinegro (ACa 49.0 ± 1.3, LCa 50 ± 2.4; Rojas-Jiménez et al, 2014). La importancia de esta región corporal radica en que permite establecer diferencias existentes en los estudios comparativos por sexo dentro de la raza y entre razas (Contreras et al, 2012).…”

“…Sin embargo, para generar un modelo morfométrico armónico de la raza fue necesario someter tales variables a un análisis de correlación lineal simple para determinar el grado de asociación entre las medidas morfométricas. Cuando en un grupo de animales o razas más del 50 % de las variables están correlacionadas, corresponde a un modelo morfométrico armónico; cuando 25 a 50 % de las variables están correlacionadas se define como un modelo medianamente armónico, mientras que cuando sólo están correlacionadas menos del 25 % de las variables corresponde a un modelo poco armónico (Contreras et al, 2011;Rojas-Jiménez et al, 2014).…”
