Comparison of milk yield based resilience indicators across dairy cattle breeds

Abstract

Resilience is increasingly recognized as an important trait for dairy cattle to improve their functioning and welfare. The log transformed variance (LnVar) and autocorrelation (rauto) of daily milk yield deviations from an expected lactation curve have been studied as potential resilience indicators, so far only using data of Holstein Friesian cattle. The aim of this research was to compare the resilience indicators between different breeds present at Dutch dairy farms and to estimate the effect of crossbreeding on these indicators. Significant differences in LnVar and rauto were found across twelve breeds, with the breed effects on LnVar different from the effects on rauto. We estimated negligible heterosis effects for rauto and LnVar. This study suggests that different breeds respond differently to environmental disturbances and that different breeds might have different levels or types of resilience.
