Genetic relationship among reproductive traits in Nellore cattle
(Cambridge Univ Press, 2015-05-01)
In order to achieve improvements in production efficiency in livestock, herds of high sexual precocity and good fertility are needed. These traits increase the availability of animals in herd, either for sale or selection, ...
