Abstract

The authors inadvertently omitted funding information for this study. The correct Acknowledgments section reads as follows: This study was supported by the earmarked fund for the China Agriculture Research System (CARS-36; Beijing, China), the National Natural Science Foundation of China (32150610478; Beijing, China), and the Program for Changjiang Scholar and Innovation Research Team in University (IRT_15R62; Beijing, China). We also thank the Dairy Association of China (Beijing, China) for providing the pedigree datasets. The authors have not stated any conflicts of interest. Genetic analyses of blood β-hydroxybutyrate predicted from milk infrared spectra and its association with longevity and female reproductive traits in Holstein cattleJournal of Dairy ScienceVol. 105Issue 4PreviewKetosis is one of the most prevalent and complex metabolic disorders in high-producing dairy cows and usually detected through analyses of β-hydroxybutyrate (BHB) concentration in blood. Our main objectives were to evaluate genetic parameters for blood BHB predicted based on Fourier-transform mid-infrared spectra from 5 to 305 d in milk, and estimate the genetic relationships of blood BHB with 7 reproduction traits and 6 longevity traits in Holstein cattle. Predicted blood BHB records of 11,609 Holstein cows (after quality control) were collected from 2016 to 2019 and used to derive 4 traits based on parity number, including predicted blood BHB in all parities (BHBp), parity 1 (BHB1), parity 2 (BHB2), and parity 3+ (BHB3).
