'No evidence' for an action means we have not yet found any studies that directly and quantitatively tested this action during our systematic journal and report searches. Therefore we have been unable to assess whether or not the action is effective or has any harmful impacts.

One replicated, before-and-after study in the UK reported that monkeys spent longer feeding in bowls positioned at the top of an enclosure than in bowls positioned on the floor.  Collected Evidencehttp%3A%2F%2Fconservationevidence.com%2Factions%2F1328http%3A%2F%2Fconservationevidence.com%2Factions%2F1328Thu, 13 Oct 2016 08:22:00 +0100Collected Evidence: Collected Evidence: Primates: Formulate diet to reflect nutritional composition of wild foods (including removal of domestic fruits) One before-and-after study in the USA found that replacing milk with fruit juice in gorilla diets led to a decrease in regurgitation and reingestion. One replicated, before-and-after study in the UK found that when lemurs were fed a fruit-free diet aggression and self-directed behaviour were lower.  Collected Evidencehttp%3A%2F%2Fconservationevidence.com%2Factions%2F1329http%3A%2F%2Fconservationevidence.com%2Factions%2F1329Thu, 13 Oct 2016 08:27:19 +0100Collected Evidence: Collected Evidence: Primates: Modify ingredients/nutrient composition seasonally (not daily) to reflect natural variability No evidence was captured for the effects of modifying ingredients/nutrient composition of primate feed seasonally (not daily) to reflect natural variability.

One before-and-after study in Italy found that in the presence of their groupmates monkeys ate more unfamiliar foods during the first encounter.  Collected Evidencehttp%3A%2F%2Fconservationevidence.com%2Factions%2F1343http%3A%2F%2Fconservationevidence.com%2Factions%2F1343Thu, 13 Oct 2016 08:56:07 +0100Collected Evidence: Collected Evidence: Primates: Feed individuals in subgroups No evidence was captured for the effects of feeding individual primates in subgroups.
