Are animals bred to make meat and produce milk more ethically than chickens bred by other humans?
A new study suggests the answer is yes, and it’s an important step toward more humane animal husbandhood.
The new study is the first to compare the welfare of a large group of captive chickens raised for meat production with that of an entirely unrelated group of chickens raised in the wild, and to look at their reproductive histories.
The researchers also looked at how many eggs they produced and whether they were viable.
The researchers found that the birds produced significantly fewer eggs than those raised in a controlled environment.
They produced a lower percentage of viable embryos.
And they produced fewer viable chicks than those in wild-caught chickens, which means the chickens that they bred in captivity had fewer offspring and thus less chance of reproducing.
The study authors concluded that the animals raised in factory farms were far more likely to be prone to human illness, disease and mortality than chickens that were raised in nature.
And the poultry raised in commercial poultry facilities also had more risk of disease and illness.
“The research clearly demonstrates that the welfare outcomes of captive-raised chickens are not comparable to those of their wild counterparts,” said the study’s lead author, Dr. Jonathan Coyle, a veterinarian at the University of Wisconsin-Madison.
The research team looked at two different populations of captive broiler chickens raised on farms and in zoos in Europe and the United States.
They found that at first glance, the birds in the captive broilers seemed to have a higher risk of developing health problems.
But the researchers found the animals in the zoos had similar reproductive outcomes as their wild ancestors.
The goal of the study was to determine how closely related the two populations of chickens were to each other, the researchers said.
But they found that their genetic data matched.
The authors noted that they used the same method for each group of birds, so that it would be hard to determine whether the results held true for all of the broiler chicken populations.
They also used the method for their wild-raised poultry, which meant the researchers could compare how the birds behaved during different times of the year.
The scientists noted that it’s difficult to determine which is the best way to raise poultry because there are several factors that influence how healthy an animal is when raised in different conditions.
For instance, a broiler bird raised in an artificial cage may be healthier in terms of its weight and health because it has a higher metabolic rate.
But the researchers noted that chickens raised with a wild-bred mother and a mother raised in captivity are very similar to each another.
They said the same should be true of chickens in commercial facilities.
They said that the research suggests that the way an animal breeds in the home environment should be considered a critical factor when determining how healthy it is.
But they said it’s still important to keep in mind that not all broilers and chicken populations are created equal.
For example, the chickens raised as pets in the United Kingdom tend to be sicklier, more likely for infections and less healthy than those born in captivity.
And it’s not clear that captive chickens, who are raised in their natural environments, will fare as well.
The USDA’s National Institute of Food and Agriculture said that broiler birds, chickens and other animals raised for food are often used in laboratories as a model of animal welfare, and that this work could help educate consumers on the welfare practices of different animal species.
