Nutritional composition of the diet of Alouatta palliate Mexicana females in different reproductive states

Observational data on the feeding and behavior of a semi free-ranging troop of mantled howler monkeys (Alouatta palliata mexicana) were collected and analyzed to determine whether differences exist in the nutritional composition of the diet of females at different reproductive states. The reproductive states selected for study were non-gestation (control), gestation, and lactation. Mean ingestion was calculated in grams/day and...

Effect of dietary fiber concentration on apparent digestibility and digesta passage in non-human primates. II. Hindgut-and Foregut fermenting folivores.

Two test diets with different acid detergent fiber (ADF) concentrations (15% ADF, 30% ADF) were fed to seven adult hindgut- and seven adult foregut-fermenting primates. Apparent digestibilities (%) of dietary dry matter (DM), gross energy (GE), and fiber components (neutral detergent fiber [NDF], ADF, hemicellulose [HC], and cellulose [C]) were measured. Rates of digesta transit (TT1) and retention (RGIT) times...

Vitamin D metabolites 25(OH)D and 1,25(OH)2D and Kidney function indices and the relationship to diet in Goeldi’s monkeys (Callimico goeldii)

In Brookfield Zoo’s Goeldi’s monkey colony, a large number of deaths related to renal disease has been documented. Review of post-mortem results from Goeldi’s monkeys in the past 20 years revealed that in deaths of animals over 18 months of age, renal disease was a primary pathologic diagnosis. Although the nutrient requirements of Goeldi’s monkeys have not been described, these...

Trace element intake of Cercopithecinae

The Fe, Zn, Cu, Mn and Mo intake was determined in 5 species of Cercopithecinae kept in captivity. The feed dry matter contained up to three times higher concentrations of trace elements compared to humans’ mixed and vegetarian diets. Although the mean body mass of the animals only amounted to 8% of the body mass of humans, they had a...

Chemical composition of Southeast Asian Colobine foods

Digestive disturbances have been considered a major health issue among captive colobines [Janssen, 1994; Calle et al., 1995]. Inadequate or inappropriate fiber sources may underlie some of these problems. Apart from maintaining normal gastrointestinal function [Van Soest, 1994 ], one critical issue in husbandry of these species is the necessity of providing a suitable diet for supporting pregastric [Stevens, 1988]...

Do new world primates really have elevated needs for protein and Vitamin D?

Phylogenetic variation in nutrient requirements is of both theoretical and practical interest. Although all vertebrates are thought to require a similar set of nutrients, quantitative needs can vary in relation to digestive, physiologic and reproductive performance (Allen and Oftedal, 1996). For example, among primates it is likely that the nutrient requirements of colobine monkeys such as colobus (Colobus) and langurs...

Callitrichids: nutrition and dietary and husbandry

Meeting the nutritional needs of Callitrichids is essential to their survival and reproduction in captivity. Development of appropriate dietary guidelines involves information on 1) feeding ecology, 2) published nutrient requirements, often from studies of laboratory primates, 3) food preferences, and 4) foods available in zoos for diet formulation. This monograph is meant to provide a general overview of the feeding...

Leaf-eating primates: nutrition and dietary husbandry

Species differences in natural feeding habits and digestive system structure suggest that all captive primates should not be fed in the same manner.28 Primates whose diets consist primarily or exclusively of leaf material possess highly developed, and delicately balanced digestive systems, which enable them to utilize this abundant food source. The order of Primates consists of several species whose natural...
