Why are high-sugar, low-fiber cultivated fruits avoided for captive wildebeest?

Answer

They can cause gastro-intestinal disturbances

While wild populations may occasionally supplement their diet during scarcity, captive populations must adhere strictly to appropriate forage types. High-sugar, low-fiber cultivated fruits are deliberately avoided when feeding captive wildebeest because this type of diet is known to disrupt their specialized digestive systems, frequently resulting in adverse gastro-intestinal disturbances for the animals.
