Latency to eat the concentrate or silage plus hayTime elapsed since heifers put the head in the restrainer until they start to eat the concentrate or silage plus hay (minutes)
Time eating the concentrate or silage plus hayEffective time spent eating the concentrate or silage plus hay without pauses (minutes)
Vocalizations of low magnitudeNumber of vocalizations performed with the mouth almost closed during their restrained period at the feed bunk
Vocalizations of high magnitudeNumber of vocalizations performed with the mouth wide open during their restrained period at the feed bunk
Sniffing, coughing, sneezingNumber of events when heifer sniffed or coughed or sneezed during their restrained period at the feed bunk
PausesNumber of times heifers interrupted eating the concentrate during one minute or more during their restrained period at the feed bunk
Tongue rollingNumber of events when heifers rolled their tongue during their restrained period at the feed bunk
