Female fertility in a Guzerat dairy subpopulation: Heterogeneity of variance components for calving intervals
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The objectives of the present study were to determine if variance components of calving intervals varied with age at calving and if considering calving intervals as a longitudinal trait would be a useful approach for ...
Genetic parameters for reproductive traits of crossbred buffaloes from Brazil, estimated by Bayesian inference
(2013-12-01)
The objective of the study was to estimate heritability for calving interval (CI) and age at first calving (AFC) and also calculate repeatability for CI in buffaloes using Bayesian inference. The Brazilian Buffaloes Genetic ...
Genetic Parameters for Reproductive Traits of Crossbred Buffaloes from Brazil, Estimated by Bayesian Inference
(Int Buffalo Information Ctr, 2013-01-01)
The objective of the study was to estimate heritability for calving interval (CI) and age at first calving (AFC) and also calculate repeatability for CI in buffaloes using Bayesian inference. The Brazilian Buffaloes Genetic ...
Genetic parameters for milk yield, age at first calving and interval between first and second calving in milk buffaloes
(2007-12-01)
Genetic parameters for the relation between the traits of milk yield (MY), age at first calving (AFC) and interval between first and second calving (IBFSC) were estimated in milk buffaloes of the Murrah breed. In the study, ...

Parturition intervals and distributions of parturitions by months of buffalo in Southern and South-eastern Brazil
(2007-12-01)
Reproductive rate is an important component of economic success in livestock production. Parturition interval (IEP) is a direct measure of the productivity of the animal. Long IEP reduce the number of calves produced per ...

Estimates of genetic parameters for stayability and their associations with traits of economic interest in Gir dairy cows
(Funpec-editora, 2016-01-01)
The objective of the present study was to estimate genetic parameters for stayability at 60 months of age (STAY60) and its association with first lactation cumulative milk yield (P305), age at first calving (AFC), and first ...
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 ...
