Once a Pig, Always a Pig

Cloned animals same as uncloned peers

THURSDAY, Jan. 9, 2003 (HealthDayNews) -- A pig is a pig is a pig -- even if it's cloned.

Texas A&M University researchers compared the behavior of cloned pigs to normal pigs and found the cloned pigs behave like other pigs.

The study included two litters of cloned pigs and two litters of normal pigs. They were compared in tests that measured food preference, temperament and how they spent their time. The researchers also compared the pigs' physical characteristics, such as weight, length and growth rate.

The study found the cloned pigs and the normal pigs had the same kinds of variable behavior in terms of their play, sleeping, fighting and response to outside stimuli. Their physical characteristics were also similar.
