Care of the Infant and Juvenile Gibbon (Hylobates lar)
A breeding colony of six female and seven male gibbons (Hylobates lar) has been maintained at Litton Bionetics, Inc. (LBI) since July 1973, when they were obtained as a group from a pharmaceutical firm. At that time, all animals in the colony were mature or nearly so and had been in the United States for 2–5 years. The first attempts at breeding these animals began 10 months after they arrived at our facility, and in the intervening 2 years, 12 pregnancies have been diagnosed among the six females currently in the colony. These 12 pregnancies have resulted in six live births (two males and four females) with two cases of fetal wastage and four animals still pregnant.
