"The Guzerat breed is well adapted to the tropical conditions of Brazil. After 1940, the widespread use of Guzerat cattle for crossing has reduced its population size," scientists in Brazil report.
"In 1994, a selection program for milk production traits was initiated in some purebred herds. However, its success is compromised by genetic drift and an increased inbreeding coefficient (F). The objective of this study was to evaluate the genetic status of the Guzerat population under selection for milk production in order to monitor genetic variability. Genealogical data from 10,051 animals were used to estimate genetic parameters. The average F for all animals and for inbred...
