Phenotypic modeling of residual feed intake using physical activity and methane production as energy sinks.

Journal of dairy science - 1 Aug 2020

Abstract excerpt

Residual feed intake (RFI) is a measure of feed efficiency in dairy cattle. This study modeled phenotypic RFI of first- and second-parity Holstein and Jersey dairy cows within 9 lactation segments (consecutive segments of 4 wk each) covering the first 36 lactation weeks. We aimed to evaluate physical activity and daily methane production as additional energy sinks in the estimation of RFI, to examine the...
