Parentage testing and effect of misidentification on the estimation of breeding value in Gir cattle

Abstract: A correct relationship among sires is essential for an efficient breeding program. Microsatellite markers were used in progeny tests, to assess the paternity of seventy-four probable offspring of nine Gir dairy sires. A 36% misidentification rate was observed; however, these errors had minimal effects on the ranking of the nine bulls with regard to their genetic values. The results suggest that paternity tests should be performed in breeding programs, in order to prevent inappropriate paternities from influenc… Show more

“…The combined exclusion probability value for the 10 loci was 0.9989, an acceptable value more than ideal for parentage tests (Baron et al, 2002). Jia et al (2004) showed that the CEP value was 0.9957 for Holstein Friesian cattle using six microsatellite markers, while Radko et al (2002) obtained a CEP value of 0.9999 using 11 microsatellites and it is known that the CEP values found in Nellore cattle is lower than that of other taurine breeds (Heyen et al, 1997).…”

“…Paternity misidentification has been shown to vary from 10 to 20% in breeding programs in developed countries (e.g., Banos et al, 2001;Visscher et al, 2002;Weller et al, 2004;Jiménez-Gamero et al, 2006) and was estimated to be over 35% in Gyr cattle breeding in Brazil (Baron et al, 2002).…”

“…Otros estudios similares en la raza Brahman reportan valores semejantes, tales como 0,999 (Riojas et al 2009) y 0,993 (Gómez et al 2013), con el uso de 11 y 8 marcadores, respectivamente. Algunos estudios en otras razas reportaron valores de PEC que variaron de 0,842 a 0,999 al utilizar entre 6 a 10 marcadores microsatélite (Baron et al 2002, Curi y Lopes 2002, Visscher et al 2002, Carolino et al 2009). En todos los estudios se reitera la importancia del uso de los marcadores con mayor poder discriminatorio, ya que al descartar marcadores de baja informatividad, se puede aumentar la PEC con un menor número de marcadores.…”

“…Se han reportado tasas más altas de paternidades erróneas en ganado Gyr de Brasil (Curi y Lopes 2002), con 27,5% de rechazo en las paternidades (padre vs progenie vs. madre). Baron et al (2002), reportaron una tasa de identificación errónea (padre vs. progenie) de 36% y 22% en al menos 1 o 2 marcadores, respectivamente. Por otra parte, Rehout et al (2006) reportaron porcentajes de paternidad errónea en ganado Holstein de 10,7%.…”
