The dairy cows can be optimistic or pessimistic from a young age and their inherent perspective can & # 39; predicts their ability to cope with stress, new research from the University & # 39; British Columbia says.

Benjamin Lecorps, PhD student in animal welfare program, said the study has implications for animal welfare and suggests some commonalities between human and animal world.

"In humans, we know that the characteristics of personality can really affect how people cope with stress, coping with challenges or even affect their social life and so on. We really wondered if it was also applicable to -Customized, "said Lecorps.

The study, published work last month in Scientific Reports, examined how the calves were previously identified as & # 39; awesome & # 39 ;, sociable, pessimistic or optimistic reacted in & # 39; stressful situations as they transported from barn to another.

The stress tests came four & # 39; months after their personality characteristics were identified through testing when the animals were between 25 and 50 days.

The most pessimistic calves were more vocal and high temperatures were in the eyes, which are signs of & # 39; tension, he said.

The eye temperature increase when the animal feels threatened because the sympathetic nervous system is activated and increases blood flow to the eyes, said Lecorps.

While optimism has been studied as a key predictions about how humans cope with & # 39; stressuri, b & # 39; implications for social life and their mental health, just over pessimism focused studies and optimism in other species, he said.

Lecorps said the features of personality have often been studied as an average over species or herd, but it is important to look at individuals when considering the welfare of animals as calves are vulnerable to challenges from others.

The study can & # 39; is used to help farmers determine which animals will be more durable and to enable them to improve overall health in & # 39; dairy farm, he said.

"If we are animals more vulnerable to stress, x & # 39; is likely to be more likely to be later ill in life or substandard & # 39; of & # 39; challenging situations are subject in dairy -trobbija of & # 39; routine ", said Lecorps. .
