Productive life, survival, discards and deaths of cows in different crosses of dairy breeds in a grazing system

The objective of this work was to evaluate the duration of productive life, survival to subsequent calving, discards and deaths in different crosses of dairy breeds in a grazing commercial dairy farm.

Vaca lechera adaptación fertilidad longevidad bienestar Dairy cow adaptation fertility longevity welfare The objective of this work was to evaluate the duration of productive life, survival to subsequent calving, discards and deaths in different crosses of dairy breeds in a grazing commercial dairy farm. Retrospective data from a commercial farm in the province of Santa Fe, Argentina, were analyzed. The period evaluated ranged from August 1, 2017, to January 12, 2021. The database consisted of 1,342 lactations of pure Holstein breed (HO; n: 799 cows), 344 lactations of HO x Jersey cross (JY; n: 164 cows), 190 lactations of the JY x Montbeliarde cross (MO; n: 96 cows) and 316 lactations of the MO x HO cross (XB; n: 134 cows). No significant differences were found between the survival curves of the productive life variable between the pure HO breed and the evaluated crosses (p=0.1281). When the survival to subsequent calving was analyzed, it was found that all the crosses were superior both in the second and in the third calving, with respect to the pure HO cows. No significant differences were found in culling and mortality variables between HO cows and the different crosses. It is concluded that the length of the productive life was similar between the pure breed HO and the studied crosses JY, MO and XB. Finally, culling and deaths were similar between the purebred (HO) and the JY, MO and XB crosses, although MO cows showed the lowest mortality rates. El objetivo de este trabajo fue evaluar la duración de la vida productiva, la supervivencia a los partos posteriores, los descartes y muertes en diferentes cruzamientos de razas lecheras en un tambo comercial a pastoreo. Se analizaron datos retrospectivos de un tambo comercial de la provincia de Santa Fe, Argentina. El período de tiempo evaluado fue desde el 1 de agosto del 2017 al 12 de enero del 2021. La base de datos constaba de 1342 lactancias de raza Holstein puras (HO; n: 799 vacas), 344 lactancias de cruza HO x Jersey (JY; n: 164 vacas), 190 lactancias de la cruza JY x Montbeliarde (MO; n: 96 vacas) y 316 lactancias de la cruza MO x HO (XB; n: 134 vacas). No se hallaron diferencias significativas entre las curvas de supervivencia de la variable vida productiva entre la raza HO pura y los cruzamientos evaluados (p=0,1281). Cuando se analizó la supervivencia a los partos posteriores, se encontró que todos los cruzamientos fueron superiores tanto en el segundo como en el tercer parto, con respecto a las vacas HO puras. No se encontraron diferencias significativas en las variables descarte y muerte entre las vacas HO y las diferentes cruzas. Se concluye que la longitud de la vida productiva fue similar entre la raza pura HO y los cruzamientos estudiados JY, MO y XB. Finalmente, los descartes y las muertes fueron similares entre la raza pura (HO) y los cruzamientos JY, MO y XB, aunque las muertes en las vacas MO mostraron los menores valores.
