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