Invited review: The welfare of dairy cattle housed in tiestalls compared to less-restrictive housing types: A systematic review.

open access: yesJournal of Dairy Science, 2021
Many dairy cattle worldwide are housed in tiestalls, meaning that they are tethered by the neck to individual stalls. On some farms, tied cattle are permitted seasonal access to pasture, but otherwise their movements are restricted compared with cows ...

An alternative interpretation of residual feed intake by phenotypic recursive relationships in dairy cattle

open access: yesJDS Communications, 2021
There has been increasing interest in residual feed intake (RFI) as a measure of net feed efficiency in dairy cattle. Residual feed intake phenotypes are obtained as residuals from linear regression encompassing relevant factors (i.e., energy sinks) to ...

Estimation of 305-day milk yield from test-day records of Chinese Holstein cattle

open access: yesJournal of Applied Animal Research, 2018
This study compared six models, namely the Gaines, Sikka, Nelder, Wood, Dhanoa and Hayashi models, for the estimation of 305 days milk yield in Chinese Holstein cattle. We compared their ability to reliably predict 305-day lactation yield from incomplete
