Summary: The objective of the present study was to describe the frequency of the main racial traits of Morada Nova sheep and simulate the impact of this culling on the response to selection for birth weight. The data from sex, coat colour, hoof pigmentation, muzzle pigmentation, polled and cryptorchidism were collected individually at weaning from 385 Morada Nova sheep of the red variety, born between 2010 and 2012, which belonged to four different flocks in the state of Ceará, Brazil. To estimate the impact of culling of animals due to racial pattern on the genetic improvement of the Morada Nova population, the genetic gains in birth weight per generation were calculated considering the following different scenarios of culling due to racial pattern in a simulated population. The present results indicate that the most urgent step is flexibilization of the requirement of dark muzzles and hooves. The selection of Morada Nova sheep based on racial pattern has caused losses in the genetic gain for productive traits such as birth weight. Readaptation of the official racial pattern established for Morada Nova sheep is necessary so that the racial pattern is achieved and an adequate number of animals will be available for selection. Resumen: El objetivo del presente estudio fue determinar la frecuencia de los principales rasgos raciales de las ovejas Morada Nova y simular el impacto del descarte por incumplimiento del patrón racial sobre la respuesta a la selección por peso al nacimiento. Los datos de sexo, colour de la capa, pigmentación de las pezuñas, pigmentación del hocico, falta de cuernos y criptorquidia fueron tomados individualmente al destete sobre 385 corderos Morada Nova de la variedad roja, nacidos entre 2010 y 2012. Estos corderos pertenecieron a cuatro rebaños distintos del estado de Ceará, en Brasil. Para estimar el efecto del descarte de animales por incumplimiento del patrón racial sobre la mejora genética de la población Morada Nova, los incrementos genéticos del peso al nacimiento por generación fueron calculados considerando las siguientes situaciones de descarte por patrón racial en una población simulada. Los resultados indican que la medida más urgente es la flexibilización del requisito de hocico y pezuñas oscuros. La selección del ganado ovino Morada Nova por patrón racial ha causado pérdidas de ganancia genética en caracteres productivos tales como el peso al nacimiento. Se hace necesario readaptar el patrón racial oficial establecido para el ganado ovino Morada Nova de tal manera que se pueda alcanzar el patrón racial manteniendo aun así un número adecuado de animales disponibles para la selección.
