An important goal in animal breeding is to improve longitudinal traits; that is, traits recorded
multiple times during an individual's lifetime or physiological cycle. Longitudinal traits were …

ABSTRACT A good health status of high-performing dairy cows is essential for successful
production. Feed intake affects the metabolic stability of dairy cows and can be used as a …

A total of 17 356 test-day milk yield (TDMY) records from 642 first lactations of Alpine goats
were used to model variations in lactation curve using random regression models (RRM) …

Accurate prediction of daily milk production is a crucial aspect of the dairy industry. During
the past decades, although many models using various data analytic techniques have been …

After calving, high-yielding dairy cows mobilize body reserves for energy, sometimes to the
detriment of health and fertility. This study aimed to estimate the genetic correlation between …

We proposed multiple-trait random regression models (MTRRM) combining different
functions to describe milk yield (MY) and fat (FP) and protein (PP) percentage in dairy goat …

Residual feed intake (RFI) is considered as a measurement of feed efficiency, which is
greatly related to the growth performance in pigs. Daily feeding records can be obtained …

Background Egg production traits are economically important in poultry breeding programs.
Previous studies have shown that incorporating genomic data can increase the accuracy of …

The objectives of the present study were to estimate genetic parameters of monthly test-day
milk yield (TDMY) of the first lactation of Brazilian Holstein cows using random regression …

The objectives of the study were to estimate genetic parameters for milk production traits of
Holstein cattle using random regression models (RRMs), and to compare the goodness of fit …
