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

Real-Time Cattle Interaction Recognition via Triple-stream Network [PDF]

open access: yesarXiv, 2022
In stockbreeding of beef cattle, computer vision-based approaches have been widely employed to monitor cattle conditions (e.g. the physical, physiology, and health). To this end, the accurate and effective recognition of cattle action is a prerequisite. Generally, most existing models are confined to individual behavior that uses video-based methods to
