Impacto de las evaluaciones genéticas en las tendencias genéticas de bovinos Jersey y Suizo Americano en México

Abstract: Introducción: El hato bovino lechero especializado nacional presenta pocas estimaciones de tendencias genéticas estimadas en años recientes. Esta falta de información limita la evaluación del progreso genético obtenido y la estimación del impacto de las evaluaciones genéticas (EG) nacionales. Los objetivos del estudio fueron cuantificar el progreso genético de las poblaciones bovinas lecheras Jersey y Suizo Americano, antes y después de la implementación de las EG nacionales, así como analizar las prin… Show more

“…Small and medium-scale herds in Mexico, predominantly Holstein, may benefit from evaluating alternative genotypes like Jersey for better adaptation to diverse conditions (Larios-Sarabia et al, 2020). However, a declining trend in genetic progress for certain breeds, as identified in previous studies, highlights the importance of restructuring national genetic improvement programs (Boichard et al, 2015;Larios-Sarabia et al, 2020).…”

“…The ARIMA models consisted of autoregressive (AR) and moving average (MA) components, integrating an order of differentiation (d) to ensure stationarity (Kirchgassner, 2007). Stationarity, crucial for the Box-Jenkins methodology (Box et al, 2015), was tested using the Dickey-Fuller (D-F) test: H: YtI(1); H1: YtI(0) (Dickey and Fuller, 1979).…”

“…The quantification of a population's genetic advancement can be determined by assessing its response to selection or genetic inclination. The latter assesses the genetic alterations achieved through the selection process over time (Larios, et al, 2020). Biotechnologies like AI Artificial Insemination and IATF Fixed Time Artificial Insemination have been crafted primarily for enhancing genetics within the livestock sector (Marizancen, 2017).…”
