Digestibility and passage of standard zoo diet fed to greater mouse deer (Tragulus napu)

Conklin N.L., . and Dierenfeld E.S., . Digestibility and passage of standard zoo diet fed to greater mouse deer (Tragulus napu). pp. 41-51. ISSN 0025-1291

Feeding trials were conducted on 11 adult greater mouse deer Tragulus napu in 5 mixed sex groups at the Wildlife Conservation Park Bronx New York USA to quantify aspects of digestive physiology. Diets consumed contained (as-fed basis): 63 low fiber (16 ADF) commercial herbivore pellets 25 raw yam 7 kale and 6 fruit. Total feed intake averaged 6.4 of body mass; dry matter intake was 4.4. Apparent digestibilities of dry matter (75.8) crude protein (77.2) and total cell wall (42.2) were high on this medium/low fibre diet (25.8 NDF). Passage marker studies (three 6-day trials on one animal) revealed: mean transit time averaged 49.0 9.5 h peak 27.3 3.6 h and 5 to 95 retention time 16.0 0.0 h to 82.7 18.1 h. Mean transit was longer in the greater mouse deer compared with previously published data for the lesser mouse deer Tragulus javanicus. Additionally measured digestive capability in the greater mouse deer appeared superior to that of domestic sheep on the same fibre level

Abstract

Feeding trials were conducted on 11 adult greater mouse deer Tragulus napu in 5 mixed sex groups at the Wildlife Conservation Park Bronx New York USA to quantify aspects of digestive physiology. Diets consumed contained (as-fed basis): 63 low fiber (16 ADF) commercial herbivore pellets 25 raw yam 7 kale and 6 fruit. Total feed intake averaged 6.4 of body mass; dry matter intake was 4.4. Apparent digestibilities of dry matter (75.8) crude protein (77.2) and total cell wall (42.2) were high on this medium/low fibre diet (25.8 NDF). Passage marker studies (three 6-day trials on one animal) revealed: mean transit time averaged 49.0 9.5 h peak 27.3 3.6 h and 5 to 95 retention time 16.0 0.0 h to 82.7 18.1 h. Mean transit was longer in the greater mouse deer compared with previously published data for the lesser mouse deer Tragulus javanicus. Additionally measured digestive capability in the greater mouse deer appeared superior to that of domestic sheep on the same fibre level
