Estimates of genetic correlations between days to calving and reproductive and weight traits in Nelore cattle
(2005-01-01)
Data comprising 53,181 calving records were analyzed to estimate the genetic correlation between days to calving (DC), and days to first calving (DFC), and the following traits: scrotal circumference (SC), age at first ...
Avaliação do Desempenho ao Primeiro Parto de Fêmeas Nelore e F1
(1999-07-01)
The objetive of this study was to compare the first calving performance of Nellore and F1 crossbred cows. Data used in the study came from 741 calving of Nellore and F1 cows born from the matting of Nellore cows with sires ...
Identification of genomic regions related to age at first calving and first calving interval in water buffalo using single-step GBLUP
(Wiley-Blackwell, 2020-10-05)
In Brazil, water buffaloes have been used to produce milk for mozzarella cheese production. Consequently, the main selection criterion applied for the buffalo genetic improvement is the estimated mozzarella yield as a ...

Genetic parameters for milk yield, age at first calving and interval between first and second calving in milk Murrah buffaloes
(2010-02-01)
In the present study, data of 1,578 first lactation females, calving from 1985 to 2006 were analysed with the purpose of estimating genetic parameters for milk yield (MY), age at first calving (AFC) and interval between ...

Comparison of models for the genetic evaluation of reproductive traits with censored data in Nellore cattle
(2016-06-01)
In typical genetic evaluation, often some females have missing records due to reproductive failure and due to voluntary and involuntary culling before the breeding season. These partially or unobserved phenotypes are known ...
