Nutritional status of free-ranging Mexican howler monkeys (Alouatta palliata mexicana) in Veracruz, Mexico: Serum chemistry; lipoprotein profile; vitamins D, A, and E; carotenoids; and minerals
Abstract 10.1002/zoo.10078.abs The purpose of this work was to measure important nutritional status parameters for a group of free-ranging Mexican mantled howler monkeys (A. palliata mexicana) and compare those data to published data for primates. The nutritional status of six free-ranging Mexican mantled howler monkeys was examined using biochemical analysis. Blood samples were analyzed for […]
Phytochemical and mineral components of foods consumed by black howler monkeys (Alouatta pigra) at two sites in Belize
Abstract 10.1002/1098-2361(2000)19:23.3.CO;2-4 We analyzed the chemical composition of the diets of eight groups of free-ranging black howler monkeys (Alouatta pigra) in Belize, Central America. The study groups were located in two different forests: the Community Baboon Sanctuary (CBS) and the Cockscomb Basin Wildlife Sanctuary (CBWS). Two of the study groups were translocated from the CBS […]
Nutritional composition of the diet of Alouatta palliata mexicana females in different reproductive states
Abstract 10.1002/(SICI)1098-2361(1999)18:63.3.CO;2-I 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. […]
Effect of dietary fiber concentration on apparent digestibility and digesta passage in non-human primates. II. Hindgut- and foregut-fermenting folivores
Abstract 10.1002/(SICI)1098-2361(1999)18:63.3.CO;2-6 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 […]
The role of minerals in food selection in a black howler monkey (Alouatta Pigra) population in Belize following a major hurricane
As plants may contain low levels of some minerals including sodium, copper, and phosphorous, herbivores may become deficient in these nutrients. In 2001, Hurricane Iris hit the Monkey River Forest in Belize causing substantial damage to the food supply of the black howler monkey population (Alouatta pigra) living there. This included an 18-month absence in […]
