Brazil has the largest herd of beef cattle in the world, estimated at approximately 200 million
animals. Production is predominantly pasture-based and low input and hence time to …

Data from 23,120 Nellore animals were used to estimate genetic parameters for age at first
calving, average gains from weaning to yearling and from yearling to after yearling, weaning …

Com objetivo de estimar parâmetros genéticos para perímetro escrotal medido aos 12
(PE12) e aos 18 meses de idade (PE18) de machos e peso a um ano de idade (P365), peso …

Dados de 14.918 animais da raça Nelore nascidos entre 1991 e 2000, provenientes de
rebanhos localizados nas regiões Sul e Sudeste do País, foram utilizados para estimar …

Components of (co) variance and genetic parameters were estimated for adjusted weights at
ages 120 (W120), 240 (W240), 365 (W365) and 450 (W450) days of Polled Nellore cattle …

Age at first calving (AFC) measures the entry of heifers into the beef cattle production
system. This trait can be used as a selection criterion for earlier reproductive performance …

Neste trabalho foram analisadas 286 observações de intervalo do primeiro ao segundo
parto (IEP1) e 1.106 observações de intervalo de partos, considerando-se todos os partos …

The total meat yield in a beef cattle production cycle is economically very important and
depends on the number of calves born per year or birth season, being directly related to …

This research evaluated a multivariate approach as an alternative tool for the purpose of
selection regarding expected progeny differences (EPDs). Data were fitted using a multi-trait …

In southern Brazil, beef cattle production systems generally rely on grazing on natural
pastures. However, their forage production, and consequently metabolizable energy (ME) …
