Reproduction
With the gestation period lasting around 160 days, the gazelles tend to breed in the winter and give birth in the early spring. Before giving birth, the mother will separate herself from the heard to give birth and then hide the newborn in the thick underbrush outside the herd, returning occasionally to nurse it. This occurs for the first month until the newborn begins to eat vegetation, but still relying on nourishment from its mother.
The Cuvier’s gazelle is one of the few gazelle species to frequently give birth to twins (40.5%), with singlets weighing an average of 2.99 kilograms (6.59 lb) and twins weighing an average of 2.85 kilograms (6.28 lb). Ten days after giving birth, the females may breed again, giving birth to two sets of offspring per year. Newborn females can become fertile as early as 27 weeks and can give birth as soon as 70 weeks of age.
As herbivorous ruminants, the diet of a Cuvier’s gazelle entirely contains leaves, grass, and other vegetation. They will consume large amounts of greenery and find a cool place during the day to finish chewing their cuds, remnant wads of food that return from the stomach (eructation) to be chewed a second time for further digestion.

“The chief function of the city is to convert power into form, energy into culture, dead matter into the living symbols of art, biological reproduction into social creativity.”
—Lewis Mumford (1895–1990)
“It is so characteristic, that just when the mechanics of reproduction are so vastly improved, there are fewer and fewer people who know how the music should be played.”
