A common management practice in commercial dairy herds is to separate the calf from the cow the day after birth. After the cow and her calf have been separated they both vocalize, but what is yet to be determined is if after only being together for one day can the cow and calf recognize each other’s vocalisations and whether they respond to the calls made following the separation. Immediately following birth, 12 Holstein cow-calf pairs were moved into a single pen. Approximately 24h after birth the cow-calf pair was separated, the cow remained in the pen, while the calves were moved into individual pens in another building. The calls made by the cow and calf in the 24h period following the separation were recorded and strung together in a sequence to be played back to the animals 24h after separation. The cows and calves were also played white noise. The cows showed a stronger response to the calf vocalisations when compared the white noise. The heart rate of the cows was elevated after hearing the recording of their calf. The cows also responded by increasing the movement of their ears and heads. The cows could also distinguish between their calf and a strange calf as, they would move their heads less when their calf’s called was played compared to a strange calf’s call. The calves responded to the cows’ vocalisations, in contrast to their response to white noise, with increased head movements and fewer ear flicks. When the calf’s mother’s call was played, the calves responded with an increased heart rate, increased ear movements and decreased head movements, versus the responses to strange cow calls. The general inability of the cows and calves to definitely differentiate between the mother\/offspring versus unknown animal calls may be due to the lack of time spent together which would have prevented them from learning one another’s calls. However, past research has shown that cows and their calves are able to identify individuals through auditory clues at a very early age.<\/p>\n","protected":false},"excerpt":{"rendered":"
