"We recently received healthy offsprings of Chinkara, Gaur and four-horned antelope. While Chinkara and Gaur gave birth to a young one each, four-horned antelope gave birth to two offsprings," Riyaz Khan, zoo curator said.
The animals that gave birth were brought to the zoo as part of the National Zoological Park's exchange programmes, he said.
The young ones will be put on display only after the 'weaning period', which is the time period wherein animals cease to be dependent on the mother.
The doctor noted that the mother animals are being fed vitamin supplements.
"Sometimes mothers eject the babies. In that case, zoo officials have to hand-raise them. The weaning period usually takes 2-3 months, after which the offsprings start taking food." Bhawal said.
Delhi zoo currently houses 4 Chinkara, 7 four-horned antelopes and 6 Gaur (Indian bison).
