Some pigs tend to be optimistic while others are pessimistic, according to a new research that is meaningful to animal welfare. The study, published in the journal Biology Letters, is the first to show that mood and personality interact in an animal, influencing judgment.
Asher, a researcher at the University of Newcastle's Institute of Neuroscience, and her team housed groups of pigs in two types of environment. One reflected standard commercial conditions and the other was cushier with more space and plenty of soft, deep straw. After the pigs got accustomed to these new homes over a few weeks, the researchers picked 18 pigs from each type to train and test their judgment.
“To do this, we trained each pig. In one corner of a training room there would be a bowl with chocolate sweets — pigs love them — and at the opposite side of the room there would be a bowl containing coffee beans, which pigs find bittertasting,” a researcher said.
Over a number of training trials, pigs learned to go to the bowl reliably when it was in the corner where they had figured out to expect chocolate sweets. On the contrary, they quickly learned to avoid the bowl when it was in the corner where they would expect to find the coffee beans.
The researchers next placed an unfamiliar bowl in different locations, to see how the pigs would react. Some gaily dashed to the bowl no matter what was inside, showing optimism that it would contain their favorite sweets. Others, however, behaved as though they expected it to contain coffee beans, displaying pessimism.
The findings suggest that a onesizefitsall answer to animal welfare issues does not exist. Even if pigs are just equal to bacon or other meat for some people, there is still cause for concern. Studies have suggested that how an animal is treated during its lifetime can directly affect meat quality and taste.
1.What was the study trying to figure out?
A.How to make pigs happier.
B.The similarities between humans and pigs.
C.How living environment affected pigs' mood.
D.How pigs' mood and personality affected their judgment.
2.What does the underlined word “cushier” in Paragraph 2 mean?
A.Simple. B.More comfortable.
C.Unpractical. D.Less free.
3.What do the findings of the new research imply?
A.People should treat pigs equally.
B.People's health relies on meat quality.
C.People should meet pigs' various needs.
D.People's attitude toward pigs is totally wrong.
