Dataset of management and growth curve derivatives to predict first lactation milk yield

This dataset presents management and modeled variables of 78 Holstein-Friesian heifers. Spreadsheets consist of seven sets of training and testing data randomly split with replacement.

In each spreadsheet, the included variables are:

Variable name
Description

ID
Heifer ID tag

Mes
Month of birth of the heifer

Estacion
Birth season, according to Mes

L_305_F_2x2
First lactation milk yield is calculated as the integral from day 1 to 305 of a Fourier model representing daily milk yield (kg)

Edad_IA
Heifer's age at effective artificial insemination

servicios
Number of inseminations

Edad_1P
Heifer's age at first calving

P_parto
Heifer's weight at first calving (kg)

B_parto
Heifer's condition score at first calving

Sexo_C
Calf sex

Peso_C
Calf weight at birth (kg)

wt_3._F, wt_6._F, wt_9._F, wt_12._F, wt_15._F, wt_18._F, wt_21._F
Heifer's weight at various months after birth, as per a Fourier model of Heifer's growth curve (kg)

X1STd_3._F, X1STd_6._F, X1STd_9._F, X1STd_12._F, X1STd_15._F, X1STd_18._F, X1STd_21._F
First derivative at several months after birth, based on a Fourier model of Heifer's growth curve

X2STd_3._F, X2STd_6._F, X2STd_9._F, X2STd_12._F, X2STd_15._F, X2STd_18._F, X2STd_21._F
Second derivative at several months after birth, based on a Fourier model of Heifer's growth curve

wt_3._L to wt_21._L, X1STd_3._L to X1STd_21._L, 

X2STd_3._P to X2STd_21._P
