Genetic correlations between heifer subsequent rebreeding and age at first calving and growth traits in Nellore cattle by Bayesian inference
(Funpec-editora, 2012-01-01)
We estimated heritability for subsequent rebreeding (SR) of heifers and genetic correlations between this trait and weaning weight (WW), weight gain from weaning to yearling (WG), age at first calving (AFC), and mature cow ...
Influence of genetic type and level of concentrate in the finishing diet on carcass and meat quality traits in beef heifers
(Elsevier B.V., 2012-03-01)
Carcass and meat quality traits of thirty-six feedlot beef heifers from different genetic groups (GG) fed at two concentrate levels (CL) were evaluated using 12- Nellore (NE), 12 - 1/2Angus x 1/2Nellore (AN) and 12 - ...

Progesterone dose during synchronization treatment alters luteinizing hormone receptor and steroidogenic enzyme mRNA abundances in granulosa cells of Nellore heifers
(Elsevier B.V., 2021-02-01)
The objective was to investigate effects of progesterone (P-4) dose on abundance of luteinizing hormone receptor (LHCGR), aromatase (CYP19A1), 3 beta-hydroxysteroid dehydrogenase (HSD3B1), and other steroidogenic mRNA ...
Genetic evaluation of the probability of pregnancy at 14 months for Nellore heifers
(Amer Soc Animal Science, 2002-04-01)
To estimate the heritability for the probability that yearling heifers would become pregnant, we analyzed the records of 11,487 Nellore animals that participated in breeding seasons at three farms in the Brazilian states ...

Digestion of feed fractions and intake of heifers fed hydrolyzed sugarcane stored for different periods
(Sociedade Brasileira de Zootecnia, 2012-07-01)
The objective of this study was to evaluate, in Nellore heifers, intake and digestibility of hydrolyzed sugarcane stored for different periods. The experimental design used was a 4 × 4 Latin square, four diets, four Nellore ...
