AGUDELO-GOMEZ, Divier Antonio. Results genetic evaluation for milk production until day 270 in buffalas in colombia, 2018. Ces. Med. Vet. Zootec. [online]. 2019, vol.14, n.1, pp.100-129. ISSN 1900-9607.  https://doi.org/10.21615/cesmvz.14.1.7.

The sixth genetic evaluation, for milk production up to day 270 in buffalos in Colombia, was carried out in collaboration between the CES University and the Asociación Colombiana de Bufalistas (ACB). The pedigree of 77,602 buffaloes and productive of 34,195 lactations of 9,969 buffalo were used from 15 herds. To estimate the heritability and the Predicted Transmitting Ability (PTA) of the animals, an animal model was used in which random effects were included: the genetic additive, the permanent environment and the residual effect; as fixed effects were used: number of calving and contemporary group. The average milk production was 989.2 kg. The estimated heritability was 0.31, this value suggests that the selection can be used as strategy to increase milk production in the Colombian buffalo herd. In the annexed files the lists of the animals (breeders and youngsters) with the best PTAs are presented.

Keywords : lactation breeding program; selection.
